Sperm Made From Female Bone Marrow, Men Obsolete? 459

Posted by ScuttleMonkey from the what-some-women-have-been-saying-for-years dept.
Shaitan Apistos writes "British scientists have discovered a way to turn female bone marrow into sperm, allowing women to reproduce without the need of male companionship. All children born of this method would be female, due the lack Y chromosomes, and there is high chance of birth defects. Eggs also can be created from male bone marrow, but men looking to reproduce would still need to find a surrogate mother to handle the gestation period. I'd like to take a moment to welcome our new amazonian overlords and remind them that men are still very good at mowing lawns and fixing cars."

    From a sexual point of view, most women are still part conditioned and part pre-programmed to want male ahem companionship. (I could put this much more crudely but I won't). Without these urges our species wouldn't exist. You can't suddenly replace that in a generation. If you had many generations that could survive just as well (ie elliminate high birth defects etc) perhaps you'd see human sex drive die off. I like sex, so let's hope not.

    From a social and evolutionary point of view, while men and women can replace each other for most things it is still true that the male tends to be physically bigger and buliker, and prefer science and math while women tend to be smaller and have more interests in social bonds, fashion and nest-making. We'd need to change both society and biology to change that. (Note that I'm not saying a man can't be a splendid nest-maker or that a woman can't do heavy work, or even that this should be discouraged - nothing sexier than a woman with a brain, or one that can kick arse - I'm just stating what the trend is currently and that it takes time to change such trends.)

    So while a few scornful women may wish to bomb men out of existence but we ain't going anywhere anytime soon. Let's all be friends, instead.

        Doesn't this also allow women to reproduce without the need of female companionship? Just make sperm from your own marrow and use this to fertilise your own eggs. Of course the daughter would then be a clone of the mother. But she would only inherit birth defeats, not engender new ones.
        • It wouldn't be a clone of the mother, as genes that existed in the mother may not be in the offspring, and genes that there was only one of in the mother could have 2 in the offspring.
          • Which bring up an interesting point about why the birth defects are so likely: with cloning you end up with an individual who is identical.

            With this, essentially combining two seperate strands of DNA, if a woman uses sperm generated from herself, you basically have the most extreme case of inbreeding imaginable. Birth defects between siblings or parent/children pairings are so high because they share roughly 50% of their genetic code. Sharing 100% and "mating" would be VERY likely to cause problems.

          They've pretty much proven that both gender and sexual preference are hardwired into the brain (lots of studies, some quite good, one or two quite unethical (I read a story about one where they cut a babies penis off at birth and raised him as a girl.. of course as soon as he got the chance he reverted to being male - he 'knew' he was male despite nobody ever telling him)).

          If course there's two ways that a 'reverse' preference could happen... either it's genetic, or something happens during the development of the foetus.

          I seem to remember a pair of identical twins, one gay one straight, though (can't provide a link as it's too vague for even google to help) which would count against the genetic theory.

        Come to that, why should people with disabilities be allowed to stick around, when a fully able-bodied society would be perfectly viable? Why should people with dark skin be allowed to stick around, when a fully-white society would be perfectly viable? Why should Jews be allowed to stick around, when a fully Jew-free society would be perfectly viable?

        Most people view such questions as shocking, revolting, taboo. We have collectively decided that such questions simply have no place in our lives. We do not need any explanations or justifications: the idea that all these groups have a fundamental and irrevocable right to exist is taken as axiomatic. It's one of the foundations of our modern western civilisation, period, and there is simply no further room for debate.

        The question of whether men should be "allowed" to exist is the same question, asked in a different way. Therefore the answer, to people in our society, will be the same: of course men must be allowed to exist. No justification will be required.

        While feminists like to exaggerate the bad properties and general uselessness of men and the superior characteristics of women, they fail to realize that those properties have been genetically selected by their sexual counterpart. If men are really that useless, this must mean that women really suck at selecting a sexual partner.

      From a sexual point of view, most women are still part conditioned and part pre-programmed to want male ahem companionship.

      I take it you haven't fathered any offspring. That "want" you're referring to is at its height during the brief courtship phase. Past that, it's replaced with something very different.

      Here's how it works. The girl gets pregnant and your "companionship" privileges are revoked with occasional but increasingly rare exceptions using rules that only a woman could understand.

      The child is born. Companionship has been replaced by sharing of duties. A year or two passes, and the privileges return occasionally, but only if you've met your workload. That continues for several years (in an ideal environment) until lust and love are relegated to "remember when?" memories. The bond between the mother and child is strong and unbreakable. The bond between the two of you is weak. You're now living the life of someone who's entered into a series of complex, interwined legal and financial agreements. Satisfy all those agreements and you may reach the 6-7 year mark. Fail, or complain about the loss of companionship, you'll discover what misery really means.

      If you've come this far, and you're unhappy, then it's hookers and blackjack for you (she's busy and has "her" kids to think about). On the other hand, if she's unhappy, she will consider you as unimportant, and leave. The legal and financial agreements stay, so she gets the kids and house, and you get the bills. The world will be supportive of her decision, and you end up like a stray dog wandering the streets.

      Let's all be friends, instead.

      Only if you were friends to begins with. Good friends are sufficiently motivated to work things out. But then, ask yourself often people marry their friends?

    1.) This is an argument against all those advocating to ban same sex marriage, because they "cannot reproduce". Quite the common argument recently. Despite my second point.

    2.) THEY DID THIS FIVE YEARS AGO. Really. While I was still in high school I cheered the first time someone pulled this off. I used it in a debate with someone on the case of gay marriage. Its in my old Science News... I mean this might be a team doing it again, or doing it better, but they are still not the first.

    Just my 2 cents.

    This could be a great way towards extinction.
    1. Phase out men.
    2. When there are no men you can only breed through a procedure.
    3. Wait for a major war or some major problem where a lot of people die and a good chance many with the knowledge of the procedure will die to. (Just because the world is run by woman don't think for a second that they will solve all the problems that we have)
    4. Then a slow extinction.

    Generally it is a bad idea. There is also the issue rejecting half of the genetic code and the biological and psyological difference that men have give a major advantage to the specie.
  • That's the craziest thing I ever heard of. As soon women get any rights, the first thing they do is stop having babies. The old 1980's battle of the sexes is a two way street. If men may be obsolete sperm providers, then it follows that a woman is useless unless she is pregnant!

    The Daily Mail is considered a tabloid rag by many of us who have lived in the UK because they cater to people with a palate for sensationalist headlines and content. The referenced New Scientist article [newscientist.com] talking about Karim Nayernia's research was published in April of 2007 but The Daily Mail chose to report it many months later. Regardless, since last year there have been few tangible gains in this field. The problem rests in the fact that converted stem cells can achieve the first 2 of 3 stages towards mature sperm development. Even once this is done there is no guarantee the sperm can actually be used in IVF to create a viable/implantable fertilized egg.

    The implications of this research are great but rags like The Daily Mail focus on the most provocative uses such as gay/lesbian couples conceiving and auto-reproduction. Before we can approve this research for use in the public we must ascertain whether the manipulations necessary to force conversion of bone marrow stem cells into spermatogonium or the products of these cells potentially introduce undetectable abnormalities within the genetic code. Next, during the process of spermatogenesis chromosomal crossover introduces genetic variability. Without more details in the original article I wonder if one of the failing stages of development involves this important process. Lastly, auto-reproduction is nearly impossible. Every person carries a set of lethal recessive alleles which manifest themselves in incestuous reproductive pairings--hence why most societies have shunned this sort of relationship. This would almost certainly guarantee the fetus would spontaneously abort.

    The real application of this research is injecting spermatogonium eggs in women or men who are infertile. This would revolutionize reproductive medicine because it would allow couples to conceive naturally. However, being in the medical field, there are very valid natural reasons why couples may not be able to reproduce (i.e. certain genetic abnormalities) or why fetuses spontaneously abort that we need to decide as a society whether its prudent to interfere. I don't claim to have the answers but I would welcome discussion in this direction so we can make informed choices in the medical breakthroughs we're bound to see in the next few decades.

    Incidentally, the New Scientist published a new article [newscientist.com] today on the matter discussing the implications of this research. Without having a subscription I can't read more but I certainly wouldn't count out fathers just yet. Having a child is only the first part of the equation. Raising an emotionally and psychologically well-adjusted child still necessitates their role--although many single-parents or LGBT couples may argue this point. Anyway, as a community I hope we're a bit more careful of citing sensationalist publications.

    But parking aside, this sounds like the kind of thing that would have us in genetic hot water in only a few generations. It would be much more encouraging to hear about research into the "shrinkage" [wikipedia.org] of the y-chromosome that seems to be occurring in humans and some other mammals. It would be nice to be able to "fix" this if it ever becomes a real problem.

  • The late Valerie Solanas [wikipedia.org] would have been thrilled [sbc.edu] to hear this news.
  • The summary states all children conceived this way would have a high risk of birth defects. But the article only states that there is a high risk of birth defects if the same woman is both the mother and father. It does not say anything about a high risk of birth defects if two people make a child that way.
