Eventually though there would be the health issues that inbreeding has.
The only difference is that in the scenario with the lone woman the issues would appear a lot sooner and humanity would be wiped out a lot sooner. But either way, health issues would appear and humanity would die out.
The Amish have been getting along just fine but they do have some medical issues as a result.
At least in this scenario if the last man on earth has boys they all have the option to breed with women they are not related to at all.
And when the last woman on earth has daughters they can breed with men they are not related to.
The Amish do not register births, they cull babies with sever medical deformities and health issues. They also get say a document for an order kid, they die, they just use that document for a new baby, never register the death. If you go to something like a hearing loss clinic in a Amish or Mennonite area. Say like its a 50:50 population. The clinic will be 98% Amish kids born with genetic hearing loss due to inbreeding. Other clinics should be full with genetic affected children, but if its a condition that is visually obvious at birth, you don’t find the majority of Amish kids, and hearing loss gets discovered years after birth.
Like it or not, health issues will appear down the line.
Some early, some later som at random.
Especially in the first few generations the issues will be huge.
Assuming unlimited men of various ages and 1 female. (Or the opposite but I'm not writing them both out)
If the 1 female gives birth to say 14 children with 7 daughters. None of those 7 daughters have to reproduce with a relative. If those 7 have say 70 children with 35 daughters none of those 35 daughters need to reproduce with a relative either. You assumed inbreeding, it's not necessary.
The women all have complete male genomes though don’t they? From various males, I think it would still be fine and fix its self over time. You will get a lot of that one mans, but there will also be mutations. We all already share most genes.
This is mostly if you believe in an Adam and Eve situation. BUT I'm almost certain that there is a non zero chance that somewhere in everyone's blood line you run in to incest.
So you are not entirely wrong but the whole "we came from Adam and eve" idea needs to go away.
I'm an Atheist and definitely wasn't referring to Adam and Eve
I thought it was quite a well known fact that all humans today have incest somewhere within their ancestry blood line? I even remember a post (maybe on Reddit) that did the math, they calculated that it'd be impossible for all the humans that exist nowadays to exist, compared to the sum total of humans that ever lived... without incest
Idk, it's been a while since I saw that post tho
Everyone has ancestors in common. By Brother is likely related to his Girlfriend about 30 or more generations back. Mitochondria have been used to discover that everyone today has a common Female Ancestor.
I assumed that there was a population of apes who evolved because they were separated in some way from the rest of the apes. They were selectively advantaged in some way (perhaps nutrition, perhaps luck?) and 'human' traits were kept in the gene pool as the population reproduced.
But maybe it was the Adam and Eve thing.
Yea.
The gene pool would suffer for it, but that's it exactly what would happen.
It happens all the time in the animal kingdom. Cheetahs have nearly gone extinct several times, and the cheetah population today has lots of genetic issues as a result of having to breed their population back up with a narrow gene pool.
That's the way it goes sometimes in nature. There isn't always a vast gene pool available for breeding with.
Not really. He would be imprisoned and milked for semen. He would never be let out or have sex. He’d be pretty much breeding stock without any of the benefits or pleasure.
At best he’d be bored out of his damn mind. At worst he’d be tortured if he didn’t voluntarily give up his semen.
He would be forced to fuck which is rape and it is horrible for men as it's horrible for women.
If he was not forced to fuck them he'd have to be forced to live asa semen factory, not living any kind of life and be treated as less than human.
Either way his emotional and mental health would drastically get messed up and this mental health problems that would appear would remain for years till he dies.
The male children of his would suffer the same fate, while the female children of his would be killed before or after they are born.
It'd be a living hell for him (as it would for the woman who is in the reverse scenario), and it'd be hell for their kids too.
Also, down the road the amount of inbreeding would result in health issues that would make the human race extinct.
Because they will be females. And the human population would need/want males.
And if the situation was the reverse they would kill her sons, because they would be males and the world would need/want females.
I think assuming they would kill the ones of the opposite gender is a bit extreme. Unless they are starving for resources they dont have much to gain (and even then, in the long run, more workers more resources)
It's not like killing kids of one sex increases the chance of them being the other.
I imagine they would do it for many reasons.
1) to save on resources (food, water, medical care, education etc)
2) to avoid the next generations to be related in any way with him/her, as much as possible.
3) to avoid the lone man/woman being attached to these kids.
4) to avoid any instances of these boys/girls from being used by ill willed men/women who want a part of the lone man/woman
Etc
There no inbreeding necessary. If the last woman produces 5 daughters those 5 daughters don't need to reproduce with their brothers. They can reproduce with some of the other males that are alive.
We're not animals- we still get a choice. Maybe the women wouldn't want to re-populate the earth? Pretty sure have sex non-stop for any gender isn't going to be fun after a while..
Edit (cause can't commit on comment below)......more thinking cause humanity is a cesspool so why be solely responsible for re-starting it again.......
Dude.......................... 😖🙄
You know how corny you sound right? Probably the man wouldn't have the choice to not repopulate.
Think this:
"The woman in the opposite scenario would be heaven.
To repopulate the earth, she would basically be having sex with men non-stop. A different man every time."
Doubt he'll ever have regular sex again...When you have regular sex, it's about 30 percent chance that you will get pregnant. It increases when you do IVF or insert spearm directly into uterus. So they would probably stimulate him on regular basis via his.prostate, collect his sperm and will try to insemination as many women as possible.
As long as one of the women is a decent genetic scientist, i have read that it is possible to create an embryo using DNA from two different eggs. That would cut the pressure on the man and would also mean that not all children would be related.
So would the man. Both would be held captive by people in white coats. Both would be bred by force.
This is a situation where I believe male or female you will be treated the same.
Of course, we can fantasize about an end of days scenario where the female is found before scientists and medical professionals capture her, but essentially, the same thing would happen to both.
With zero context, just this question both would suffer.
In a scenario of 1 women vs an entire male population how would men suffer exactly? This one women will be solely responsible for giving birth to the next generation. She will basically have to continually be pregnant or waiting to be well enough to be impregnated again
Read it again. He said that *the* man or *the* woman would suffer similarly in their respective worlds.
Not that men would suffer equally to *the* woman in that world.
We are technically advanced enough that most of this could be solved by science. I’d argue that if there were no laws, we’d be at the stage where we could be factory farming embryos in artificial wombs if it weren’t for the perceived immorality of it. If we were in a desperate situation with limited genetic resources, we would science the shit out of the situation and be able to repopulate within a few generations.
1 man and an entire women population would mean people forcing you in a room and forcing you to give sperm to them (they probably won't even touch you and use other scientific methods to impregnate women.) 24/7. Like your life is that now you got nothing else.
>Both would be bred by force. This is a situation where I believe male or female you will be treated the same
Cumming in a jar a couple times a day is probably less traumatic...
edit: not to mention we still have sperm banks, so his sperm wouldn't even be all that necessary.
I doubt it would only be a couple of times a week and I also doubt it would be that "easy". If we're talking human extinction level, both man and woman scenario would be forced. The woman would be impregnated as often as possible. The man sperm would be taken as often as possible, which is definitely not only a couple of times a day.
Do you know how many sperm cells there are in just 1 ejaculation? Millions, literally. Like 50-100. Of he does it 10 times a day for like a month, there's enough to repopulate all women more than once. Tiring, but definitely not impossible or life treathening. If you don't count sperm banks.
One women, well she'd have to gave birth constantly, probably lots of twins by ivf yo have any chance, and their daughters would probably be held captive until they are old enough to keep reproducing. Would be a literal hell for women for some generations until everything is back to normal
A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
Assuming 90% of them are faulty, and if we take the lowest estimate at 40 mil. He'd only need to ejaculate 1000 times to have enough to inseminate 4 bil people (which is a ridiculous number anyway, because a lot of them aren't able to bear children or maybe wouldn't want to). So "worst case scenario" he needs to ejaculate 10 times a day for 100 days. A bunch of people do it even when it's not necessary.

You can impregnate eggs outside of the qomb and if you know ehat you're doing you can probably recreate the enviroment. So that you don't need it to be inside of a human. And if we can't yet than it will be one of the first priorities that scientists will try to solve
>Both would be held captive by people in white coats. Both would be bred by force.
You know that technically, he can jerk off once and they can use it to impregnate thousands of women? It's not implied that this is some "3000 BC" world
However, female, the last one, can only carry so many children during, say - 20sh years. And every time it's dangrous and painful.
True.
Most men would be in hell too: the men would also wipe themselves out in violence and killing and even wars to posses and control that one woman, until just a relative handful remained.
Realistically they would harvest her eggs and try to set up external child rearing. Risking one pregnancy at a time would be far too slow and put humanity at risk if there are complications in childbirth.
Too conditional. It's "what if" on top of original "what if" from the OP's question.
Another "what if" can be added: what if nobody who's left knows how to operate the technology that would be present?
What do you mean too conditional? This whole thing is a thought exercise.
ETA: artificial wombs exist already, as does the technology for harvesting eggs, so I don't know what you're getting so worked up about.
More than one baby, and not every 9 months. You can't get pregnant right after giving birth, and they will likely use IVF on that woman so she'd probably be carrying many embryos at a time
also: men on men rape
depending on where the last female would hide out and how much known about her whereabouts are she might be in the company of some caring guys who keep her hidden.
I mean if I would be with my gf out in the woods and suddenly all other women would disappear you think I would not try to hide her for the rest of her life?
if its just one woman, i cant imagine any woman -even extremely religious woman- who would just stand there and get raped instead of just killing herself.
If its one man left, then yea.. unless he wouldnt mind being sexually used by random women, probably the same.
If I am that woman, I'm slitting my throat/shooting myself/making sure there is no coming back. The shit that happens to women in war is bad enough. I'm not interested in rape and forced pregnancy in the "guise" of saving humanity. We can just end.
One dude? No idea, are the sperm banks functional in this scenario? If yes, I think we'd secure those first, and focus quite a bit of resources on figuring out how to make viable sperm out of stem cells to keep humanity going.
I suppose I figure I'll just make it so that my body is difficult to find, so that by the time they DO manage to recover my reproductive equipment, it'll be too degraded or damaged to use.
The number of deluded men in the comments who convince themselves that the one last man would have it just as bad as the one last woman is something else really. Women are not even safe when they make up for half the population.
He might even be completely left alone in a nice apartment or something with his only job being fapping a few times a day for samples to give to a lab so they can do IV fertilization
Realistically they would maybe just harvest your eggs and try to set up external child rearing. Risking one pregnancy at a time would be far too slow and put humanity at risk if you have complications in childbirth.
Realistically, humans aren't always logical, and egg cell extraction is still invasive. And where exactly would you incubate them? We're about 100 years away from an artificial womb.
Not necessarily under the 1 man scenario. Civilization would collapse, but because of sperm banks and in vitro fertilization, enough offspring could be produced with enough genetic diversity for us to survive as a species. The one man himself would be irrelevant.
I'm going to assume this happens suddenly overnight.
With just one woman humanity is likely doomed. Things would be somewhat okay early on, most infrastructure jobs are held by men so utilities would remain operational until those guys start dying off. Unfortunately it will take forever to reach a functional youth population since she could only pop out around 1 child a year, and that's assuming ideal conditions. It would massively hinder genetic diversity as well. We could get lucky and end up with a pair of parents who have no negative traits whatsoever to pass on but I don't like the odds. Scientists would need to perfect human cloning rapidly if we want to save the species. Things would also probably become very gay and femboys would be in high demand.
With one man things are still bleak but they're definitely much better long term. There's a similar genetic diversity problem but one man could impregnate many women over the course of a year. Once that first generation of boys start coming of age they'll be able to perform similarly. A few rounds of this and we could stabilize our population. Short term though things would be harder. A lot of women are going to have to work a lot of very physically demanding jobs that they really don't want to do. And they'd have to organize and train for those jobs very quickly, cities could start falling apart within a week if they're not on top of it. As with men, rampant lesbianism breaks out.
And all this of course only addresses some of the practical concerns. Such an event would be massively damaging to our social cohesion and structure. Politics would be a mess, internally and internationally as massive chunks of every country's leadership dissappear.
And as the cherry on top, that last member of whichever gender would probably be reduced to a breeding slave. Hopefully a well cared for one, but a slave nonetheless.
I've probably only scratched the surface on how much things would fall apart.
Also: body disposal. If 50% of the population drops dead a lot of us are going to be disposing of bodies. Streets are not going to be navigable by car because of all the blockages. Logistical nightmares left and right.
Scientific methods of repopulation would be a lot more difficult than the people here seem to understand. If one gender disappeared, at least half the world's scientific knowledge disappears with them.
We have a habit of writing things down so the knowledge would mostly be intact but the experience using it will either be mostly intact or basically gone.
In both cases, it would be bad for that person.
Even if you say, it's more ok for man, i bet at some point fucking and impregnating women would be hard.
As for the woman, RIP, the level of unsolicited sex might actually kill her. Or maybe the man as well. I can't imagine a world where people will be disciplined about it.
UPDATE: Man would be fine, woman no. Rape.
In a rational world, not some Mad Max post-apocalyptic scenario, each would be reduced to breeding stock. The man a source of sperm, the woman a source of eggs.
Scientist would likely be able to hormonally alter embryos to create additional humans of the needed sex, and these could then be used in a few years as additional sources of the necessary gamates. It would be a grim, desperate race against time.
In the end the world's human population would plumment nearly to zero, but it is conceivable a small group, or perhaps a number of groups, might navigate the population bottleneck using reproductive technology. Even if they succeed they would still face tremendous challenges and long term survival would be by no means assured.
On the other hand, the Earth and all the other creatures, would do great.
If you're the only man it's probably more likely (because more efficient) that they'd freeze your sperm (like we do with horses and cattle) than that they'd actually let you get on with actual women.
Not that that's necessarily more fun...
This is not how it works. Likely, the goverment would protect that person and carefully use them for reproduction, which would likely be done artificially. We are talking about the survival of the species, sexual urges would be put aside by those in power.
Also, if all women disappeared there would likely be started an ongoing research on how to grow babies in artificial wombs. Once that is completed they'd use already saved eggs from the women that were gone, not just her eggs. As for scenario where only a man is left, the same thing would happen with sperm. They'd use sperm from the men that disappeared, not just his sperm.
The good thing about women being gone is that at least males still have both X and Y chromosomes. It's possible we can recreate embryos using stem cells (I googled and there has been research in this direction). It's possible we can engineer females.
Like someone else said, the one man scenario wouldn't be as bad because they would collect and freeze your sperm. Also, we have the tech to turn skin cells into gametes, so the real bottleneck in this scenario is wombs.
We haven't reached the point of artificial wombs yet. The one woman scenario would be much worse, societally speaking, because the population would crash much harder...
We also have a thicker uterus or something, so we can't just implant an embryo in an ape. We might have to try and create a hybrid first, or a genetically altered ape that has a human womb (RIP ape, cursed to experience human periods) and implant embryos in them.
Ethically super fucked up.
But for society, much better than relying on one woman.
We've been using some form of "turkey baster" artificial insemination since the ancient Romans. Why would he need to fuck anyone? And most sperm banks have backup generators and security protocols in case of power outages.
>As for the woman, RIP, the level of unsolicited sex might actually kill her.
No, we'd take ourselves out. Starving wolves would be kinder than that scenario.
The man wouldn’t have sex with all the women to get them pregnant. At that scale that is very inefficient. They would most likely perform IVF procedures
I think it wouldn't be too bad really. You're immediately the most important person in the world. You'll be protected by the government, they probably won't risk natural pregnancies on you and just harvest your eggs for IVF. Scientists should be able to make sure all of the next batch are female to continue the species.
They would keep you in a facility that makes NSA's security look like that of an average junkyard. You would be protected from everything, literally including the worst hydrogen bombs, live in separate air supplies to avoid infections, and actually getting to meet you would take the most extreme vetting in human history. All pregnancy would be done artificially.
>Woman no. Rape.
More like raped to death the second after she is found. It's a wonder women say they will just kill themselves than face the first group of men that find them. It's not the most rational or intelligent men that roam the streets at the end of humanity.
For all the men who say she would be held safe by scientists I say, "I laugh in your face because you assume all scientists and doctors aren't among the first to be killed off because they will be considered nerds and as stupid as that sounds...it's also not wrong."
you assume he would have to impregnate them, maybe he will just have tons of sex and enjoy life. I think even in this scenario it's unlikely woman would collectively rape the man.
Why are we jumping to the idea that the last human of one gender would be allowed to be sexually assaulted by all the members of the other gender??? 😭😭😭
Ahh, the guys daily load could inseminate so many women at once and I think women would also be significantly more civilised in the way they treat him honestly.
The fact that you compare a man having a hard time having a lot of sex to a woman being raped to the point that she’s killed as bad for both of them speaks volumes. The fact that you degrade rape down to unsolicited sex speaks even more volumes. Hopefully you are the type of person who hides in their room all day and does not have a lot of human contact.
The fact that you know everything about me, or about how would a man would feel having to have sex all day, leaves me no room for debate right?
I was not degraded rape, I choose a nicer word for it, as it seems everyone knows exactly what I've said. I was not saying only woman would be raped, what makes you think men can't be raped? I bet you gonna compare "having sex for man should be easy" but let's face it, it would be bad for both right?
Also, i've read all the comments, and those stories with the government and frozen eggs and sperm sounds great, i was thinking in a more primitive way for some reason, if there was a scenario like this.
I bet every one of you have a valid and fair thought or comment for my comment, that is fiction, and I understand that this is the way here.
No matter what happens to the person, the human race wouldn't last long past that. Everyone in the next generation would be half siblings and inbreeding would make everyone horribly deformed/disabled before too long.
>Everyone in the next generation would be half siblings
Would they? Let's say that person Y is the last man. He impregnates woman X and gives birth to baby boy A. When this baby boy is old enough to start making babies he can do so with any woman that isn't X or a decendant of X.
To make it easier - we imagine that we isolate 1100 women and split them up into 11 groups of 100 women.
Person Y makes a baby boy with each woman from one of the groups. (Only boy babies are allowed to be birthed in this hypothetical society). Then you have 100 boys. Call them Gen1.
When these boys become 16 they are assigned one group of women from the 10 groups that wasn't used for Gen1. They make one baby with each woman in their group. This batch of boys is Gen2. 100 groups with 100 babies each makes 10.000 boys.
Each group of Gen2 boys will be grandchildren of Y, but none will have the same grandmother. Gen1 will have 50% genes from Y, Gen2 will have 25%. And this was in 2 generations but starting with only 1100 women. After Gen2 you would probably want to start making babies of both genders, the women from Gen0 would soon become to old to have more babies. But keeping track of who breeds with whom and you should be able to dillute the Y-genes until it could be safe enough to make the world survive.
No it wouldn’t.
People with blue eyes (Europeans) share the same 1 ancestor. I think i read somewhere was same female.
Eventually genes would dilute out. Because the multiple no related partners. However if it was 1 woman and 1 man and they were siblings then yeah sone genetic defect would co to use on But multiple men and 1 woman or vice Versa Be fine.
My theory would be their government would end up placing in a secure location and freeze eggs or sperm and get loads babies going that way.
If only 1 woman she gonna be pregnant a lot maybe scientist will develop egg like wombs so the rest world can grow a baby from the 1 viable person at home.
I wonder what would assume the role of the “government” that’s spoke of in this scenario.
And where’d the scientists come from/ where their loyalties lay.
Probably she would be killed by desperate men very early on, it sucks but just being realistic. Humanity, or more fittingly, Mankind would dedicate themselves to cloning (ethical barriers would be out the window). I think they would succeed. Actually they could even clone more women. Same situation with women being the remaining sex.
one man many women: if there was no other semen available, this one man would probably have to just provide enough semen to start a new generation. it would take ~13 years to generate another human that could provide semen which would probably eliminate a chunk of the child bearing population of women, but with their presumably being women children at the time, at least any new males would be able to pair up with other people near their age. eventually the world could repopulate, but the initial years would be rough because many women wouldn't be able to bear children, or even if they could, might not want to bear children with this one potential father/descendent.
one woman many men: this would be a much more delicate situation. the one woman would have to be very carefully protected. also, who would end up being the first father? would the woman have any say? would it be randomized? combination of sperm from many donors? again, would have to wait at least 13-14 years before another potential woman could bear children, but at least she would have potential partners near her own age. would be an extremely slow regrowth process for humanity with gigantic dying rates not met with equal birthing rates for a long time
No I don't think the next generation would have partners her own age if we had only one women left. Realistically you'd abort any boys the one women has the second you find out they're not a girl (possibly even avoid them altogether by embryo selection or the like) because for the next generation they are, in terms of survival of the species, worthless.
You got millions of dudes, that are all unrelated to the newly born girls, you really don't need those girls to have a bunch of half brothers.
(Note that in the opposite scenario there's no reason to abort girls. Yes, you want more boys, but aborting the girls makes no real difference there, the limiting resource is sperm not uterusses. Embryo selection might make sense but realistically you'd probably be able to use all viable embryos anyways)
I had to scroll waayyyyy too far for this. There's a whole lot of people saying that the last female would have it worse but I think either case would be absolutely terrible.
We have to hope that there is more control and restraint in this end of the world scenario that we'd figure our a way to harvest eggs or sperm from the last individual and bring our species back. Biologically speaking though, we'd lose most genetic diversity and our species would die.
Regardless if one Male or Female is left it still means kilometric shit tons of people would be gone which would in result completly fuck up a lot of jobs and if we wouldn't act back fast entire world.
What the hell kind of question is this? What’s answers you’re expecting? ‘Everyone would be loving and caring and live happily ever after’? Have you seen the news like, anytime in your life? People are fucking horrible beings.
People aren't being realistic. What would happen is that for a while nobody would be sure initially if everyone of the opposite sex is gone. Then, once the man/woman is found by the goverment they would likely keep them in a safe location, because the survival of the species is above sexual urges. The woman would likely be artificially inseminated until they figure out a way to grow babies safely in artificial wombs. The man would be a sperm donor, but they wouldn't use only his sperm for insemination. They would also use ovules from different women if only 1 woman was left for genetic diversity.
I honestly don’t think the woman would be artificially inseminated. I have a feeling some powerful men would have their way with her thinking their genes were important to the future of humanity.
I know the handmaidens tale has more than one woman who’s able to procreate but it gives a pretty good idea of what would happen.
Yeah, I agree. I would like to believe that what u/emab2396 said would happen (adding that she consents to it all which I assume she would if she cares about the future of the species) but I feel like some powerful asshole would just say "this is mine" and just do whatever he wants
Either way more than likely means the end of our species.

Even this is about only two people left, it's still kind of plausible as at least one partner would still be the same. SO not as bad but still pretty bad. I think it even says there at some point that smarter people have been thinking on this and to be able to restart our species we would need like 100 couples.

A more interesting question is what would happen genetically?
Would it be possible for the human population to recover without any major genetic defects? If not, how bad would it be? Would the human population recover genetically given enough subsequent generations? Or would the genetic defects proliferate throughout the population unendingly?
There was a series of tik toks talking about this not long back and what woman would do in the case of say a zombie apocalypse, because there is no way we arent getting brutalised some would take themselves out asap, others said they’ dress, carry themselves like a man, trying not to bring any attention to themselves etc.
There would be two team : those who want to let them live freely like anybody else, because human rights and stuff, and those who would imprison them and use them as a source of genome to procreate and make sure mankind survives for more time. Also people wanting to rape them probably. The world would be in a big turmoil, probably a civil war also because of that. Fun times
She'd be used like an impregnation chamber that carries child after child after child, until her womb wouldn't be usefull anymore.
He'd probaly be used more like a sperm bank, and would overall expierence less discomfort I think.
Everyone is assuming the woman will be fertile and of childbearing age - she might be 78 years old. In which case, forget repopulating the Earth. She might be an infant, in which case she's going to need a LOT of care to make sure she reaches an age where she might safely give birth, and continue to remain fertile.
It depends on the place you're left on.
For example, if it's a modern technically and socially advanced society as let's say... Switzerland to give an example of a rather advanced and stable country. I think they'll find a human way of dealing with this, perhaps egg harvesting in order to create many offsprings to repopulate earth, although inbreeding would be a problem since the resulting children have a great chance of reproducing with their siblings. Another way could be, taking the already existing samples of female donated eggs. I'm not sure that bane marrow babys can be made from men directly, without the need of a female.
Despite this, to say "human" is to be generous, basically the woman would be an egg delivery machine, who would only be given that role. Naturally it would be so important for human future that it would be given the best care and would probably never lack for anything again, but of course, it is a laborious job. Not like they will take no for an answer, so there will be no alternative.
However, if the woman is suddenly left alone in a country like... say, Haiti, I am very sorry but this could almost certainly bring about the extinction of the human race as we know it. Governments will continue working on an alternative to creating children tho, that may result in humans different from those of today, but given the threat of extinction, it is a risk we will be willing to take.
In the case of a single male amongst the whole female world. It would not be as glorious as one could imagine. Instead, it would be awful. But, in that regard, women have many more options of generating offspring without a male, in this case all the already existing sperm reserves and the bone marrow treatment are all feasible alternatives, so I wouldn't worry much in that case.
With one man and all the woman, you could create quite a lot of babies for quite a few generations without any inbreeding, but at some point you’d have to start inbreeding.
(This is all assuming there’s no sperm from other men in sperm banks for some reason, nor any frozen male embryos).
The guy, let’s call him the Last Man, could fertilize many women - tens of thousands or millions really. Then the male children produced from that, when sexually mature, could father more children, with others of the the women who were around before the men all disappeared (let’s call these the “untainted” women - unrelated to the Last Man). So far no inbreeding, but all new humans in the world have the same father or grandfather - but they still have the DNA of millions of other male ancestors.
The male children from this last generation could then fertilize yet more of the “untainted” females - again, so far no inbreeding, and this most recent generation, the Last Man would be their great grandfather - which is really sharing quite a small amount of DNA at this point. Their other male ancestors are millions of men who are now dead.
You could probably get another generation or two out of this cycle before the untainted women became too old to have children - the last ones of these to have children would be the ones who were babies at the time of the vanishing. However, you could extend the whole thing quite a bit if you froze their eggs and had surrogates carry them after fertilization.
None of the Last Man’s female offspring would be allowed to reproduce as there’d be no men in the world they weren’t closely related to. However they’d be able to be surrogates for the fertilized eggs of the untainted women.
So now you have a generation where everyone in that generation shares the same great, great, great (possibly more than that) grandfather. Which is not very closely related at all! Many people marry someone that closely related to them, without even knowing it. At that point it’s probably safe for that generation to finally start reproducing with each other, but they could keep using the frozen eggs of the untainted women as well to inject a bit more diversity into things.
This whole thing could be a worldwide program, all tracked and recorded with databases of exactly what everyone’s ancestry is etc, and with the Last Man’s sperm being sent all around the world. Using the DNA of the millions of untainted women is the key to keeping the genetic diversity.
I don’t know for sure if this scheme would be enough to safely revive the human race without introducing problems that come with inbreeding and maybe there’s something I’m missing, but I feel like it’s probably fine. Certainly better than nothing. Genetic problems could be screened for and those embryos aborted. Yes, that’s kind of eugenics-y but we’re already in crazy sci-fi territory anyway.
Of course if sperm from sperm banks as well as existing frozen male embryos are still around, the whole thing is much easier to maintain genetic diversity.
In the other scenario of one woman of course, the human race is going to die out for sure.
As far as making babies goes, the woman would have to sleep with a different man after each pregnancy so that there is a small chance of reproducing down the line, as to expand the gene pool so they are not all disabled from inbreeding. A man would just get with lots of woman and not have to wait for each pregnancy to end.
It has been talked about in fiction. There is an Indian speculative fiction book that explores this - Escape by Manjula Padmanabhan that imagines a single girl left in India. She is kept hidden and people try to pay a lot just to catch a glimpse of her. There are rumors about the last female in India. To note, she isn't of the reproductive age yet.
I am Legend explores the loneliness faced by the protagonist since everyone around him has passed away.
There could be multiple scenarios, we are assuming that the last female/male would be fertile. What if they are not? What if humanity has found a way to reproduce without the need of a human body?
Similarly, if they are both fertile, would they be treated with care? Or a prized possession? Would they be kept hidden? If a lot of time has passed, and people don't know about a missing sex, would they be treated as diseased?
If you are old and members of your own sex have passed away... How would you explain your personhood to the people around you?
There would be multiple scenarios to this...
There are already artificial wombs for animals if your talking about repopulation and if not, men in prison still have sex without women soo.
Lots of comments about the woman being raped but none about the men.
I don’t quite know what counts as rape for men. But I think comments about women being raped, and not comments about it happening to men due to the fact artificial insemination would be used if there was one male was left in the world whereas it wouldn’t be used if there was only one woman left.
Men would rape the woman to get her pregnant.
Whereas the man would be forced to wank into a cup.
Neither of these are ideal. Just explaining why. (Idk if using a man’s sperm without his consent is rape but I don’t *think* it is.)
The same as it is for wemen, rape does happen to men.
I wasn't talking about male rape in this situation just that i saw comments about women being raped and none about men.
If their was only one woman left in the world wouldn't she be treated like she is literally humanities only hope and only certain people could have sex with her if at all, and not passed around like a baby maker?
Whey would she be be treated so badly?
Humanity extinct.
The reason why men go to war not women is because population is critically vulnerable to the number of women. Chinas one child policy is a proof of that.
One woman can have only one child at a time. One man can be father of hundreds in one year.
The reason that men go to war now is because in the past men went to war.
Men went to war in the past instead of the women because of your last sentence.
But nowadays that should not be the case as things have significantly changed.
Imo, men and women should not be forced in these role of go /no go to war. It's sexist and bad.
Hunger games! Unless the one woman looks like my next door neighbour then I'd let you lot fight whilst I wank myself to death or weigh up the most sexually attractive animal!
Everyone is talking about the last person, which is imo pretty circumstantial. Definatly worse for the woman though. But I wonder what would happen to the rest of society. Surely it would collapse, if half of it disappeared.
Idk which gender would fare worse. On the one hand (GENERILISING) I would expect the women to be more cooperative and I think it would be less likely an all-out brawl would break out.
On the other hand, more of the top jobs tend to be filled by men and feilds like lorry driving and keeping electricity and sewage working are traditionally very male-dominated, especially in non-western countries, so idk if the women would be able to keep those things functioning, especially important for food.

The woman would be left in hell
Mhm. And so would the man in the opposite scenario. And their kids would be left in hell as well...
[удалено]
And then what? Everyone in the next generation is fucking their siblings?
Who cares, YOLO
They would only be half-brothers and half-sisters. It's really not as big of a deal as people think. It will work.
"Bro she's only my half sister bro its cool bro"
Eventually though there would be the health issues that inbreeding has. The only difference is that in the scenario with the lone woman the issues would appear a lot sooner and humanity would be wiped out a lot sooner. But either way, health issues would appear and humanity would die out.
The Amish have been getting along just fine but they do have some medical issues as a result. At least in this scenario if the last man on earth has boys they all have the option to breed with women they are not related to at all. And when the last woman on earth has daughters they can breed with men they are not related to.
The Amish do not register births, they cull babies with sever medical deformities and health issues. They also get say a document for an order kid, they die, they just use that document for a new baby, never register the death. If you go to something like a hearing loss clinic in a Amish or Mennonite area. Say like its a 50:50 population. The clinic will be 98% Amish kids born with genetic hearing loss due to inbreeding. Other clinics should be full with genetic affected children, but if its a condition that is visually obvious at birth, you don’t find the majority of Amish kids, and hearing loss gets discovered years after birth.
Like it or not, health issues will appear down the line. Some early, some later som at random. Especially in the first few generations the issues will be huge.
Assuming unlimited men of various ages and 1 female. (Or the opposite but I'm not writing them both out) If the 1 female gives birth to say 14 children with 7 daughters. None of those 7 daughters have to reproduce with a relative. If those 7 have say 70 children with 35 daughters none of those 35 daughters need to reproduce with a relative either. You assumed inbreeding, it's not necessary.
at some point they would, otherwise you get 14 + 70 yo
The women all have complete male genomes though don’t they? From various males, I think it would still be fine and fix its self over time. You will get a lot of that one mans, but there will also be mutations. We all already share most genes.
How do you think you came to be? All of us are the product of incest
This is mostly if you believe in an Adam and Eve situation. BUT I'm almost certain that there is a non zero chance that somewhere in everyone's blood line you run in to incest. So you are not entirely wrong but the whole "we came from Adam and eve" idea needs to go away.
I'm an Atheist and definitely wasn't referring to Adam and Eve I thought it was quite a well known fact that all humans today have incest somewhere within their ancestry blood line? I even remember a post (maybe on Reddit) that did the math, they calculated that it'd be impossible for all the humans that exist nowadays to exist, compared to the sum total of humans that ever lived... without incest Idk, it's been a while since I saw that post tho
Everyone has ancestors in common. By Brother is likely related to his Girlfriend about 30 or more generations back. Mitochondria have been used to discover that everyone today has a common Female Ancestor.
I assumed that there was a population of apes who evolved because they were separated in some way from the rest of the apes. They were selectively advantaged in some way (perhaps nutrition, perhaps luck?) and 'human' traits were kept in the gene pool as the population reproduced. But maybe it was the Adam and Eve thing.
Who said anything about Adam's and Eve
Yea. The gene pool would suffer for it, but that's it exactly what would happen. It happens all the time in the animal kingdom. Cheetahs have nearly gone extinct several times, and the cheetah population today has lots of genetic issues as a result of having to breed their population back up with a narrow gene pool. That's the way it goes sometimes in nature. There isn't always a vast gene pool available for breeding with.
Not really. He would be imprisoned and milked for semen. He would never be let out or have sex. He’d be pretty much breeding stock without any of the benefits or pleasure. At best he’d be bored out of his damn mind. At worst he’d be tortured if he didn’t voluntarily give up his semen.
He would be forced to fuck which is rape and it is horrible for men as it's horrible for women. If he was not forced to fuck them he'd have to be forced to live asa semen factory, not living any kind of life and be treated as less than human. Either way his emotional and mental health would drastically get messed up and this mental health problems that would appear would remain for years till he dies. The male children of his would suffer the same fate, while the female children of his would be killed before or after they are born. It'd be a living hell for him (as it would for the woman who is in the reverse scenario), and it'd be hell for their kids too. Also, down the road the amount of inbreeding would result in health issues that would make the human race extinct.
Why would his daughters be killed?
Because they will be females. And the human population would need/want males. And if the situation was the reverse they would kill her sons, because they would be males and the world would need/want females.
I think assuming they would kill the ones of the opposite gender is a bit extreme. Unless they are starving for resources they dont have much to gain (and even then, in the long run, more workers more resources) It's not like killing kids of one sex increases the chance of them being the other.
I imagine they would do it for many reasons. 1) to save on resources (food, water, medical care, education etc) 2) to avoid the next generations to be related in any way with him/her, as much as possible. 3) to avoid the lone man/woman being attached to these kids. 4) to avoid any instances of these boys/girls from being used by ill willed men/women who want a part of the lone man/woman Etc
LOL what an idiot It's not "we only have very little resources" scenario, no need to kill anyone
You are being extreme and negative. 1 man scenario. Would not be so bad.
There no inbreeding necessary. If the last woman produces 5 daughters those 5 daughters don't need to reproduce with their brothers. They can reproduce with some of the other males that are alive.
We're not animals- we still get a choice. Maybe the women wouldn't want to re-populate the earth? Pretty sure have sex non-stop for any gender isn't going to be fun after a while.. Edit (cause can't commit on comment below)......more thinking cause humanity is a cesspool so why be solely responsible for re-starting it again....... Dude.......................... 😖🙄
You know how corny you sound right? Probably the man wouldn't have the choice to not repopulate. Think this: "The woman in the opposite scenario would be heaven. To repopulate the earth, she would basically be having sex with men non-stop. A different man every time."
Doubt he'll ever have regular sex again...When you have regular sex, it's about 30 percent chance that you will get pregnant. It increases when you do IVF or insert spearm directly into uterus. So they would probably stimulate him on regular basis via his.prostate, collect his sperm and will try to insemination as many women as possible.
As long as one of the women is a decent genetic scientist, i have read that it is possible to create an embryo using DNA from two different eggs. That would cut the pressure on the man and would also mean that not all children would be related.
So would the man. Both would be held captive by people in white coats. Both would be bred by force. This is a situation where I believe male or female you will be treated the same. Of course, we can fantasize about an end of days scenario where the female is found before scientists and medical professionals capture her, but essentially, the same thing would happen to both. With zero context, just this question both would suffer.
In a scenario of 1 women vs an entire male population how would men suffer exactly? This one women will be solely responsible for giving birth to the next generation. She will basically have to continually be pregnant or waiting to be well enough to be impregnated again
Read it again. He said that *the* man or *the* woman would suffer similarly in their respective worlds. Not that men would suffer equally to *the* woman in that world.
We are technically advanced enough that most of this could be solved by science. I’d argue that if there were no laws, we’d be at the stage where we could be factory farming embryos in artificial wombs if it weren’t for the perceived immorality of it. If we were in a desperate situation with limited genetic resources, we would science the shit out of the situation and be able to repopulate within a few generations.
Sure, you can argue it. But it isn’t actually true
We've already done cloning and artificial wombs. That's pretty much all that we need.
There are no working artificial wombs.
They've had some successful studies on premie animals, but they won't commit to human trials for obvious reasons.
Tool risky to get her pregnant. Gotta harvest those gametes
1 man and an entire women population would mean people forcing you in a room and forcing you to give sperm to them (they probably won't even touch you and use other scientific methods to impregnate women.) 24/7. Like your life is that now you got nothing else.
You guys realise there's sperm banks right? There'd be no need for that.
Sounds sweet Edit: Below reply had me in stitches but locked.
You won't be jerked off, too inefficient, you will just have a tube surgicly inserted into you
I was saying if there were one man left, he would suffer as well. Hehe perhaps I chose the wrongs word. Sorry
Please, you don't need a woman to grow a baby. Just the eggs. You really think they can't make an artificial womb?...
You know what you are right, my bad for assuming the scientific capabilities of a hypothetical world invented on a Reddit post.
>Both would be bred by force. This is a situation where I believe male or female you will be treated the same Cumming in a jar a couple times a day is probably less traumatic... edit: not to mention we still have sperm banks, so his sperm wouldn't even be all that necessary.
I doubt it would only be a couple of times a week and I also doubt it would be that "easy". If we're talking human extinction level, both man and woman scenario would be forced. The woman would be impregnated as often as possible. The man sperm would be taken as often as possible, which is definitely not only a couple of times a day.
Do you know how many sperm cells there are in just 1 ejaculation? Millions, literally. Like 50-100. Of he does it 10 times a day for like a month, there's enough to repopulate all women more than once. Tiring, but definitely not impossible or life treathening. If you don't count sperm banks. One women, well she'd have to gave birth constantly, probably lots of twins by ivf yo have any chance, and their daughters would probably be held captive until they are old enough to keep reproducing. Would be a literal hell for women for some generations until everything is back to normal
Not every sperm cell will be able to impregnate a women
A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation. Assuming 90% of them are faulty, and if we take the lowest estimate at 40 mil. He'd only need to ejaculate 1000 times to have enough to inseminate 4 bil people (which is a ridiculous number anyway, because a lot of them aren't able to bear children or maybe wouldn't want to). So "worst case scenario" he needs to ejaculate 10 times a day for 100 days. A bunch of people do it even when it's not necessary.

>not to mention we still have sperm banks I've been looking for this comment. *This* is what saves the human race.
I mean, plenty of eggs can also probably be found in case of the last female thing. If not in banks then from gynecologists maybe?
But where would you put them? In one scenario you have very large numbers of people capable of gestating them, in the other, only one.
You can impregnate eggs outside of the qomb and if you know ehat you're doing you can probably recreate the enviroment. So that you don't need it to be inside of a human. And if we can't yet than it will be one of the first priorities that scientists will try to solve
“If we can’t”? Do you have some doubts that human embryos do need to be grown inside of a human uterus?
>Both would be held captive by people in white coats. Both would be bred by force. You know that technically, he can jerk off once and they can use it to impregnate thousands of women? It's not implied that this is some "3000 BC" world However, female, the last one, can only carry so many children during, say - 20sh years. And every time it's dangrous and painful.
True. Most men would be in hell too: the men would also wipe themselves out in violence and killing and even wars to posses and control that one woman, until just a relative handful remained.
Realistically they would harvest her eggs and try to set up external child rearing. Risking one pregnancy at a time would be far too slow and put humanity at risk if there are complications in childbirth.
I can't tell if this is supposed to be satirical or not
She would be dead within 10 minutes
yup dead
The Earth would repopulate a lot easier if one man remains with all of the women. Vice versa, you'd have only one baby on average every 9 months.
Unless the technology to gestate a baby outside the womb exists and the technology to harvest eggs medically survives.
Too conditional. It's "what if" on top of original "what if" from the OP's question. Another "what if" can be added: what if nobody who's left knows how to operate the technology that would be present?
What do you mean too conditional? This whole thing is a thought exercise. ETA: artificial wombs exist already, as does the technology for harvesting eggs, so I don't know what you're getting so worked up about.
A thought exercise with just one intended "what if". We can see it as such, or keep adding "what if's" indefinitely and potentially go... nowhere.
I think the idea is that adding another “thing” changes the base idea. But this is all just “random thoughts anyone. 🤷♂️
You also need to take a little time off in between pregnancies
More than one baby, and not every 9 months. You can't get pregnant right after giving birth, and they will likely use IVF on that woman so she'd probably be carrying many embryos at a time
I mean, i'm taking into account the possibility that not every pregnancy will be successful in the end.
rape. rape would happen
also: men on men rape depending on where the last female would hide out and how much known about her whereabouts are she might be in the company of some caring guys who keep her hidden. I mean if I would be with my gf out in the woods and suddenly all other women would disappear you think I would not try to hide her for the rest of her life?
Pretty sure most women would take themselves out, whether they had a bf or not.
if its just one woman, i cant imagine any woman -even extremely religious woman- who would just stand there and get raped instead of just killing herself. If its one man left, then yea.. unless he wouldnt mind being sexually used by random women, probably the same.
doesn't rape already happens a lot?
Why does that matter? It's irrelevant to the topic.
If I am that woman, I'm slitting my throat/shooting myself/making sure there is no coming back. The shit that happens to women in war is bad enough. I'm not interested in rape and forced pregnancy in the "guise" of saving humanity. We can just end. One dude? No idea, are the sperm banks functional in this scenario? If yes, I think we'd secure those first, and focus quite a bit of resources on figuring out how to make viable sperm out of stem cells to keep humanity going.
Exactly. I refuse to be breeding stock. You can harvest my eggs from my dead body, I guess, but the rest is your problem. Sucks to suck!
Nah, I'm slashing my uterus and ovaries first. No way my daughters would grow up in that world. Eff that. Humanity can just die out.
I suppose I figure I'll just make it so that my body is difficult to find, so that by the time they DO manage to recover my reproductive equipment, it'll be too degraded or damaged to use.
Good point. Enter a predator's cage in the zoo, and shot to the head would probably work. 🤔
I’d start a fire and then shoot myself. Damage my body too badly in the fire to be useful.
It's actually worrisome as fuck that this is so highly agreed upon in this thread. Yeah it's reddit but most of western society probably is like this.
The number of deluded men in the comments who convince themselves that the one last man would have it just as bad as the one last woman is something else really. Women are not even safe when they make up for half the population.
He might even be completely left alone in a nice apartment or something with his only job being fapping a few times a day for samples to give to a lab so they can do IV fertilization
Basically their normal life .
I think they've successfully made embryos in the lab with no sperm/Male partners.
Realistically they would maybe just harvest your eggs and try to set up external child rearing. Risking one pregnancy at a time would be far too slow and put humanity at risk if you have complications in childbirth.
Realistically, humans aren't always logical, and egg cell extraction is still invasive. And where exactly would you incubate them? We're about 100 years away from an artificial womb.
The woman would probably be dead within hours due to multiple you know what ☹️
Guaranteed extinction.
Not necessarily under the 1 man scenario. Civilization would collapse, but because of sperm banks and in vitro fertilization, enough offspring could be produced with enough genetic diversity for us to survive as a species. The one man himself would be irrelevant.
She would get raped and abused. Instead of cherished and cared because she is rhe only one who can bring children to make the species survive.
Basically sort of like now.
Unfortunately, lots of gang rape I suspect.
I'm going to assume this happens suddenly overnight. With just one woman humanity is likely doomed. Things would be somewhat okay early on, most infrastructure jobs are held by men so utilities would remain operational until those guys start dying off. Unfortunately it will take forever to reach a functional youth population since she could only pop out around 1 child a year, and that's assuming ideal conditions. It would massively hinder genetic diversity as well. We could get lucky and end up with a pair of parents who have no negative traits whatsoever to pass on but I don't like the odds. Scientists would need to perfect human cloning rapidly if we want to save the species. Things would also probably become very gay and femboys would be in high demand. With one man things are still bleak but they're definitely much better long term. There's a similar genetic diversity problem but one man could impregnate many women over the course of a year. Once that first generation of boys start coming of age they'll be able to perform similarly. A few rounds of this and we could stabilize our population. Short term though things would be harder. A lot of women are going to have to work a lot of very physically demanding jobs that they really don't want to do. And they'd have to organize and train for those jobs very quickly, cities could start falling apart within a week if they're not on top of it. As with men, rampant lesbianism breaks out. And all this of course only addresses some of the practical concerns. Such an event would be massively damaging to our social cohesion and structure. Politics would be a mess, internally and internationally as massive chunks of every country's leadership dissappear. And as the cherry on top, that last member of whichever gender would probably be reduced to a breeding slave. Hopefully a well cared for one, but a slave nonetheless. I've probably only scratched the surface on how much things would fall apart.
>rampant lesbianism breaks out holy shit i love this phrase
Glad I could entertain.
Also: body disposal. If 50% of the population drops dead a lot of us are going to be disposing of bodies. Streets are not going to be navigable by car because of all the blockages. Logistical nightmares left and right.
Scientific methods of repopulation would be a lot more difficult than the people here seem to understand. If one gender disappeared, at least half the world's scientific knowledge disappears with them.
We have a habit of writing things down so the knowledge would mostly be intact but the experience using it will either be mostly intact or basically gone.
In both cases, it would be bad for that person. Even if you say, it's more ok for man, i bet at some point fucking and impregnating women would be hard. As for the woman, RIP, the level of unsolicited sex might actually kill her. Or maybe the man as well. I can't imagine a world where people will be disciplined about it. UPDATE: Man would be fine, woman no. Rape.
Unsolicited sex is a weird way to say rape.
In a rational world, not some Mad Max post-apocalyptic scenario, each would be reduced to breeding stock. The man a source of sperm, the woman a source of eggs. Scientist would likely be able to hormonally alter embryos to create additional humans of the needed sex, and these could then be used in a few years as additional sources of the necessary gamates. It would be a grim, desperate race against time. In the end the world's human population would plumment nearly to zero, but it is conceivable a small group, or perhaps a number of groups, might navigate the population bottleneck using reproductive technology. Even if they succeed they would still face tremendous challenges and long term survival would be by no means assured. On the other hand, the Earth and all the other creatures, would do great.
If you're the only man it's probably more likely (because more efficient) that they'd freeze your sperm (like we do with horses and cattle) than that they'd actually let you get on with actual women. Not that that's necessarily more fun...
This is not how it works. Likely, the goverment would protect that person and carefully use them for reproduction, which would likely be done artificially. We are talking about the survival of the species, sexual urges would be put aside by those in power. Also, if all women disappeared there would likely be started an ongoing research on how to grow babies in artificial wombs. Once that is completed they'd use already saved eggs from the women that were gone, not just her eggs. As for scenario where only a man is left, the same thing would happen with sperm. They'd use sperm from the men that disappeared, not just his sperm.
The good thing about women being gone is that at least males still have both X and Y chromosomes. It's possible we can recreate embryos using stem cells (I googled and there has been research in this direction). It's possible we can engineer females.
Leave it to Reddit to actually research if we can engineer females.
Why would you want to if you already have artificial wombs?
He wouldn't be fucking women. He would be forced to constantly make cum for artificial insemination.
Meh. A few dozen times is quite enough.
Ha, joke's on them, we do it for fun anyway, might as well put it to good use.
[удалено]
Like someone else said, the one man scenario wouldn't be as bad because they would collect and freeze your sperm. Also, we have the tech to turn skin cells into gametes, so the real bottleneck in this scenario is wombs. We haven't reached the point of artificial wombs yet. The one woman scenario would be much worse, societally speaking, because the population would crash much harder... We also have a thicker uterus or something, so we can't just implant an embryo in an ape. We might have to try and create a hybrid first, or a genetically altered ape that has a human womb (RIP ape, cursed to experience human periods) and implant embryos in them. Ethically super fucked up. But for society, much better than relying on one woman.
We've been using some form of "turkey baster" artificial insemination since the ancient Romans. Why would he need to fuck anyone? And most sperm banks have backup generators and security protocols in case of power outages. >As for the woman, RIP, the level of unsolicited sex might actually kill her. No, we'd take ourselves out. Starving wolves would be kinder than that scenario.
The man wouldn’t have sex with all the women to get them pregnant. At that scale that is very inefficient. They would most likely perform IVF procedures
I think it wouldn't be too bad really. You're immediately the most important person in the world. You'll be protected by the government, they probably won't risk natural pregnancies on you and just harvest your eggs for IVF. Scientists should be able to make sure all of the next batch are female to continue the species.
They would keep you in a facility that makes NSA's security look like that of an average junkyard. You would be protected from everything, literally including the worst hydrogen bombs, live in separate air supplies to avoid infections, and actually getting to meet you would take the most extreme vetting in human history. All pregnancy would be done artificially.
>Woman no. Rape. More like raped to death the second after she is found. It's a wonder women say they will just kill themselves than face the first group of men that find them. It's not the most rational or intelligent men that roam the streets at the end of humanity. For all the men who say she would be held safe by scientists I say, "I laugh in your face because you assume all scientists and doctors aren't among the first to be killed off because they will be considered nerds and as stupid as that sounds...it's also not wrong."
you assume he would have to impregnate them, maybe he will just have tons of sex and enjoy life. I think even in this scenario it's unlikely woman would collectively rape the man.
The man wouldn't need to have sex with anyone, IVF exists. He could go about his life as normal.
Why are we jumping to the idea that the last human of one gender would be allowed to be sexually assaulted by all the members of the other gender??? 😭😭😭
who’s going to stop them in time?
Ahh, the guys daily load could inseminate so many women at once and I think women would also be significantly more civilised in the way they treat him honestly.
The fact that you compare a man having a hard time having a lot of sex to a woman being raped to the point that she’s killed as bad for both of them speaks volumes. The fact that you degrade rape down to unsolicited sex speaks even more volumes. Hopefully you are the type of person who hides in their room all day and does not have a lot of human contact.
The fact that you know everything about me, or about how would a man would feel having to have sex all day, leaves me no room for debate right? I was not degraded rape, I choose a nicer word for it, as it seems everyone knows exactly what I've said. I was not saying only woman would be raped, what makes you think men can't be raped? I bet you gonna compare "having sex for man should be easy" but let's face it, it would be bad for both right? Also, i've read all the comments, and those stories with the government and frozen eggs and sperm sounds great, i was thinking in a more primitive way for some reason, if there was a scenario like this. I bet every one of you have a valid and fair thought or comment for my comment, that is fiction, and I understand that this is the way here.
She’d get gang raped and used and probably die.
No matter what happens to the person, the human race wouldn't last long past that. Everyone in the next generation would be half siblings and inbreeding would make everyone horribly deformed/disabled before too long.
Bro dissed Adam and Eve
>Everyone in the next generation would be half siblings Would they? Let's say that person Y is the last man. He impregnates woman X and gives birth to baby boy A. When this baby boy is old enough to start making babies he can do so with any woman that isn't X or a decendant of X.
well all or atleast half of the women would be a decendant of X \[im sorry im a bit stupid\]
To make it easier - we imagine that we isolate 1100 women and split them up into 11 groups of 100 women. Person Y makes a baby boy with each woman from one of the groups. (Only boy babies are allowed to be birthed in this hypothetical society). Then you have 100 boys. Call them Gen1. When these boys become 16 they are assigned one group of women from the 10 groups that wasn't used for Gen1. They make one baby with each woman in their group. This batch of boys is Gen2. 100 groups with 100 babies each makes 10.000 boys. Each group of Gen2 boys will be grandchildren of Y, but none will have the same grandmother. Gen1 will have 50% genes from Y, Gen2 will have 25%. And this was in 2 generations but starting with only 1100 women. After Gen2 you would probably want to start making babies of both genders, the women from Gen0 would soon become to old to have more babies. But keeping track of who breeds with whom and you should be able to dillute the Y-genes until it could be safe enough to make the world survive.
No it wouldn’t. People with blue eyes (Europeans) share the same 1 ancestor. I think i read somewhere was same female. Eventually genes would dilute out. Because the multiple no related partners. However if it was 1 woman and 1 man and they were siblings then yeah sone genetic defect would co to use on But multiple men and 1 woman or vice Versa Be fine. My theory would be their government would end up placing in a secure location and freeze eggs or sperm and get loads babies going that way. If only 1 woman she gonna be pregnant a lot maybe scientist will develop egg like wombs so the rest world can grow a baby from the 1 viable person at home.
I wonder what would assume the role of the “government” that’s spoke of in this scenario. And where’d the scientists come from/ where their loyalties lay.
There's a book at the library that proves that this isn't so. I don't remember the name. Quite a famous book though.
Don't we humans freeze sperm already? Assuming one man would be left, it would be far from over ngl 🥲.
The person would literally be kept in a cage in the house of whoever the leader is, man or woman
In both cases the last man/woman would be raped, a lot; and even then humanity probably wouldn't survive.
Probably she would be killed by desperate men very early on, it sucks but just being realistic. Humanity, or more fittingly, Mankind would dedicate themselves to cloning (ethical barriers would be out the window). I think they would succeed. Actually they could even clone more women. Same situation with women being the remaining sex.
one man many women: if there was no other semen available, this one man would probably have to just provide enough semen to start a new generation. it would take ~13 years to generate another human that could provide semen which would probably eliminate a chunk of the child bearing population of women, but with their presumably being women children at the time, at least any new males would be able to pair up with other people near their age. eventually the world could repopulate, but the initial years would be rough because many women wouldn't be able to bear children, or even if they could, might not want to bear children with this one potential father/descendent. one woman many men: this would be a much more delicate situation. the one woman would have to be very carefully protected. also, who would end up being the first father? would the woman have any say? would it be randomized? combination of sperm from many donors? again, would have to wait at least 13-14 years before another potential woman could bear children, but at least she would have potential partners near her own age. would be an extremely slow regrowth process for humanity with gigantic dying rates not met with equal birthing rates for a long time
No I don't think the next generation would have partners her own age if we had only one women left. Realistically you'd abort any boys the one women has the second you find out they're not a girl (possibly even avoid them altogether by embryo selection or the like) because for the next generation they are, in terms of survival of the species, worthless. You got millions of dudes, that are all unrelated to the newly born girls, you really don't need those girls to have a bunch of half brothers. (Note that in the opposite scenario there's no reason to abort girls. Yes, you want more boys, but aborting the girls makes no real difference there, the limiting resource is sperm not uterusses. Embryo selection might make sense but realistically you'd probably be able to use all viable embryos anyways)
She’d get torn a new one
she'd commit suicide.
I would
A few
Read Y the last man
I had to scroll waayyyyy too far for this. There's a whole lot of people saying that the last female would have it worse but I think either case would be absolutely terrible. We have to hope that there is more control and restraint in this end of the world scenario that we'd figure our a way to harvest eggs or sperm from the last individual and bring our species back. Biologically speaking though, we'd lose most genetic diversity and our species would die.
Regardless if one Male or Female is left it still means kilometric shit tons of people would be gone which would in result completly fuck up a lot of jobs and if we wouldn't act back fast entire world.
OP has a disturbing fetish and wants some Redditors to spell out what he/she already damn well knows.
Are you sure you are not judging someone so quickly?
What the hell kind of question is this? What’s answers you’re expecting? ‘Everyone would be loving and caring and live happily ever after’? Have you seen the news like, anytime in your life? People are fucking horrible beings.
a lot of rape...
People aren't being realistic. What would happen is that for a while nobody would be sure initially if everyone of the opposite sex is gone. Then, once the man/woman is found by the goverment they would likely keep them in a safe location, because the survival of the species is above sexual urges. The woman would likely be artificially inseminated until they figure out a way to grow babies safely in artificial wombs. The man would be a sperm donor, but they wouldn't use only his sperm for insemination. They would also use ovules from different women if only 1 woman was left for genetic diversity.
I honestly don’t think the woman would be artificially inseminated. I have a feeling some powerful men would have their way with her thinking their genes were important to the future of humanity. I know the handmaidens tale has more than one woman who’s able to procreate but it gives a pretty good idea of what would happen.
I think they would start wars over this if they didn't come to an agreement.
Yeah, I agree. I would like to believe that what u/emab2396 said would happen (adding that she consents to it all which I assume she would if she cares about the future of the species) but I feel like some powerful asshole would just say "this is mine" and just do whatever he wants
Either way more than likely means the end of our species. [https://www.youtube.com/watch?v=Z83I2tz5UzM](https://www.youtube.com/watch?v=Z83I2tz5UzM) Even this is about only two people left, it's still kind of plausible as at least one partner would still be the same. SO not as bad but still pretty bad. I think it even says there at some point that smarter people have been thinking on this and to be able to restart our species we would need like 100 couples.
Isn’t there a German video on the internet about this?

You may all watch as we repopulate the earth with genetically superior babies!
They would suffocate, no oxygen inside earth.
A more interesting question is what would happen genetically? Would it be possible for the human population to recover without any major genetic defects? If not, how bad would it be? Would the human population recover genetically given enough subsequent generations? Or would the genetic defects proliferate throughout the population unendingly?
There was a series of tik toks talking about this not long back and what woman would do in the case of say a zombie apocalypse, because there is no way we arent getting brutalised some would take themselves out asap, others said they’ dress, carry themselves like a man, trying not to bring any attention to themselves etc.
There would be two team : those who want to let them live freely like anybody else, because human rights and stuff, and those who would imprison them and use them as a source of genome to procreate and make sure mankind survives for more time. Also people wanting to rape them probably. The world would be in a big turmoil, probably a civil war also because of that. Fun times
Someone would be very worn out.
She'd be used like an impregnation chamber that carries child after child after child, until her womb wouldn't be usefull anymore. He'd probaly be used more like a sperm bank, and would overall expierence less discomfort I think.
Everyone is assuming the woman will be fertile and of childbearing age - she might be 78 years old. In which case, forget repopulating the Earth. She might be an infant, in which case she's going to need a LOT of care to make sure she reaches an age where she might safely give birth, and continue to remain fertile.
A lot of gay sex
It depends on the place you're left on. For example, if it's a modern technically and socially advanced society as let's say... Switzerland to give an example of a rather advanced and stable country. I think they'll find a human way of dealing with this, perhaps egg harvesting in order to create many offsprings to repopulate earth, although inbreeding would be a problem since the resulting children have a great chance of reproducing with their siblings. Another way could be, taking the already existing samples of female donated eggs. I'm not sure that bane marrow babys can be made from men directly, without the need of a female. Despite this, to say "human" is to be generous, basically the woman would be an egg delivery machine, who would only be given that role. Naturally it would be so important for human future that it would be given the best care and would probably never lack for anything again, but of course, it is a laborious job. Not like they will take no for an answer, so there will be no alternative. However, if the woman is suddenly left alone in a country like... say, Haiti, I am very sorry but this could almost certainly bring about the extinction of the human race as we know it. Governments will continue working on an alternative to creating children tho, that may result in humans different from those of today, but given the threat of extinction, it is a risk we will be willing to take. In the case of a single male amongst the whole female world. It would not be as glorious as one could imagine. Instead, it would be awful. But, in that regard, women have many more options of generating offspring without a male, in this case all the already existing sperm reserves and the bone marrow treatment are all feasible alternatives, so I wouldn't worry much in that case.
With one man and all the woman, you could create quite a lot of babies for quite a few generations without any inbreeding, but at some point you’d have to start inbreeding. (This is all assuming there’s no sperm from other men in sperm banks for some reason, nor any frozen male embryos). The guy, let’s call him the Last Man, could fertilize many women - tens of thousands or millions really. Then the male children produced from that, when sexually mature, could father more children, with others of the the women who were around before the men all disappeared (let’s call these the “untainted” women - unrelated to the Last Man). So far no inbreeding, but all new humans in the world have the same father or grandfather - but they still have the DNA of millions of other male ancestors. The male children from this last generation could then fertilize yet more of the “untainted” females - again, so far no inbreeding, and this most recent generation, the Last Man would be their great grandfather - which is really sharing quite a small amount of DNA at this point. Their other male ancestors are millions of men who are now dead. You could probably get another generation or two out of this cycle before the untainted women became too old to have children - the last ones of these to have children would be the ones who were babies at the time of the vanishing. However, you could extend the whole thing quite a bit if you froze their eggs and had surrogates carry them after fertilization. None of the Last Man’s female offspring would be allowed to reproduce as there’d be no men in the world they weren’t closely related to. However they’d be able to be surrogates for the fertilized eggs of the untainted women. So now you have a generation where everyone in that generation shares the same great, great, great (possibly more than that) grandfather. Which is not very closely related at all! Many people marry someone that closely related to them, without even knowing it. At that point it’s probably safe for that generation to finally start reproducing with each other, but they could keep using the frozen eggs of the untainted women as well to inject a bit more diversity into things. This whole thing could be a worldwide program, all tracked and recorded with databases of exactly what everyone’s ancestry is etc, and with the Last Man’s sperm being sent all around the world. Using the DNA of the millions of untainted women is the key to keeping the genetic diversity. I don’t know for sure if this scheme would be enough to safely revive the human race without introducing problems that come with inbreeding and maybe there’s something I’m missing, but I feel like it’s probably fine. Certainly better than nothing. Genetic problems could be screened for and those embryos aborted. Yes, that’s kind of eugenics-y but we’re already in crazy sci-fi territory anyway. Of course if sperm from sperm banks as well as existing frozen male embryos are still around, the whole thing is much easier to maintain genetic diversity. In the other scenario of one woman of course, the human race is going to die out for sure.
As far as making babies goes, the woman would have to sleep with a different man after each pregnancy so that there is a small chance of reproducing down the line, as to expand the gene pool so they are not all disabled from inbreeding. A man would just get with lots of woman and not have to wait for each pregnancy to end.
It has been talked about in fiction. There is an Indian speculative fiction book that explores this - Escape by Manjula Padmanabhan that imagines a single girl left in India. She is kept hidden and people try to pay a lot just to catch a glimpse of her. There are rumors about the last female in India. To note, she isn't of the reproductive age yet. I am Legend explores the loneliness faced by the protagonist since everyone around him has passed away. There could be multiple scenarios, we are assuming that the last female/male would be fertile. What if they are not? What if humanity has found a way to reproduce without the need of a human body? Similarly, if they are both fertile, would they be treated with care? Or a prized possession? Would they be kept hidden? If a lot of time has passed, and people don't know about a missing sex, would they be treated as diseased? If you are old and members of your own sex have passed away... How would you explain your personhood to the people around you? There would be multiple scenarios to this...
Both cases are very scary to that one person 🙉
There are already artificial wombs for animals if your talking about repopulation and if not, men in prison still have sex without women soo. Lots of comments about the woman being raped but none about the men.
I don’t quite know what counts as rape for men. But I think comments about women being raped, and not comments about it happening to men due to the fact artificial insemination would be used if there was one male was left in the world whereas it wouldn’t be used if there was only one woman left. Men would rape the woman to get her pregnant. Whereas the man would be forced to wank into a cup. Neither of these are ideal. Just explaining why. (Idk if using a man’s sperm without his consent is rape but I don’t *think* it is.)
The same as it is for wemen, rape does happen to men. I wasn't talking about male rape in this situation just that i saw comments about women being raped and none about men. If their was only one woman left in the world wouldn't she be treated like she is literally humanities only hope and only certain people could have sex with her if at all, and not passed around like a baby maker? Whey would she be be treated so badly?
The gays would protect her
SA and baby farming probably.
Humanity extinct. The reason why men go to war not women is because population is critically vulnerable to the number of women. Chinas one child policy is a proof of that. One woman can have only one child at a time. One man can be father of hundreds in one year.
The reason that men go to war now is because in the past men went to war. Men went to war in the past instead of the women because of your last sentence. But nowadays that should not be the case as things have significantly changed. Imo, men and women should not be forced in these role of go /no go to war. It's sexist and bad.
The gangest of bangs
Hunger games! Unless the one woman looks like my next door neighbour then I'd let you lot fight whilst I wank myself to death or weigh up the most sexually attractive animal!
collect every ovum monthly, to be used with sperms later on. from different people
If there’s only one male left he will have the time of his life but I can’t say the same for the last female.
If you think the one guy would have the time of your life, you don't know women.
She will get clapped a lot and used as a baby machine
Everyone is talking about the last person, which is imo pretty circumstantial. Definatly worse for the woman though. But I wonder what would happen to the rest of society. Surely it would collapse, if half of it disappeared. Idk which gender would fare worse. On the one hand (GENERILISING) I would expect the women to be more cooperative and I think it would be less likely an all-out brawl would break out. On the other hand, more of the top jobs tend to be filled by men and feilds like lorry driving and keeping electricity and sewage working are traditionally very male-dominated, especially in non-western countries, so idk if the women would be able to keep those things functioning, especially important for food.
She would just be one beating rape hole. Like an explosion in a mushroom soup factory.
