    The prospect of all-female conception

    By Steve Connor, Science Editor
    Friday, 13 April 2007
    Scientists are seeking ethical permission to produce synthetic sperm cells from a woman's bone marrow tissue after showing that it possible to produce rudimentary sperm cells from male bone-marrow tissue.


    The researchers said they had already produced early sperm cells from bone-marrow tissue taken from men. They believe the findings show that it may be possible to restore fertility to men who cannot naturally produce their own sperm.


    But the results also raise the prospect of being able to take bone-marrow tissue from women and coaxing the stem cells within the female tissue to develop into sperm cells, said Professor Karim Nayernia of the University of Newcastle upon Tyne.


    Creating sperm from women would mean they would only be able to produce daughters because the Y chromosome of male sperm would still be needed to produce sons. The latest research brings the prospect of female-only conception a step closer.


    "Theoretically is it possible," Professor Nayernia said. "The problem is whether the sperm cells are functional or not. I don't think there is an ethical barrier, so long as it's safe. We are in the process of applying for ethical approval. We are preparing now to apply to use the existing bone marrow stem cell bank here in Newcastle. We need permission from the patient who supplied the bone marrow, the ethics committee and the hospital itself."


    If sperm cells can be developed from female bone-marrow tissue they will be matured in the laboratory and tested for their ability to penetrate the outer "shell" of a hamster's egg - a standard fertility test for sperm.
    "We want to test the functionality of any male and female sperm that is made by this way," Professor Nayernia said. But he said there was no intention at this stage to produce female sperm that would be used to fertilise a human egg, a move that would require the approval of the Human Fertilisation and Embryology Authority.


    The immediate aim is to see if female bone marrow can be lured into developing into the stem cells that can make sperm cells. The ultimate aim is to discover if these secondary stem cells can then be made into other useful tissues of the body, he said.


    The latest findings, published in the journal Reproduction: Gamete Biology, show that male bone marrow can be used to make the early "spermatagonial" stem cells that normally mature into fully developed sperm cells.


    "Our next goal is to see if we can get the spermatagonial stem cells to progress to mature sperm in the laboratory and this should take around three to five years of experiments," Professor Nayernia said.


    Last year, Professor Nayernia led scientists at the University of Gottingen in Germany who became the first to produce viable artificial sperm from mouse embryonic stem cells, which were used to produce seven live offspring.
    His latest work on stem cells derived from human bone marrow suggests that it could be possible to develop the techniques to help men who cannot produce their own sperm naturally.


    "We're very excited about this discovery, particularly as our earlier work in mice suggests that we could develop this work even further," Professor Nayernia said.


    Whether the scientists will ever be able to develop the techniques to help real patients - male or female - will depend on future legislation that the Government is preparing as a replacement to the existing Human Fertilisation and Embryology Act.


    A White Paper on genetics suggested that artificial gametes produced from the ordinary "somatic" tissue of the body may be banned from being used to fertilise human eggs by in vitro fertilisation.

    Making babies without men - a literary view
    LYSISTRATA
    Aristophanes (c. 411BC)
    After 21 years of war, the women of Athens, led by Lysistrata, take matters into their own hands. Lysistrata suggests every wife and mistress should refuse all sexual favours until peacetime. Before long it proves effective, peace is concluded and the play ends with festivities.
    HERLAND
    Charlotte Perkins Gilman (1914)
    On the eve of the First World War, an isolated society entirely comprising Aryan women is discovered by three male explorers. The women reproduce asexually and live in an ideal society without war and domination. This feminist utopia is a 20th-century vehicle for Gilman's then-unconventional views of male and female behaviour, motherhood, individuality, and sexuality. It is said to be based on Gilman's version of utopia through Aryan separatism.
    DISAPPEARANCE
    Philip Wylie (1978)
    At four minutes and 52 seconds past four one afternoon, the world shatters into two parallel universes as men vanish from women and women from men. With families and loved ones separated from one another, life continues very differently as an explosion of violence sweeps one world while stability and peace break down in the other.
    THE CLEFT
    Doris Lessing (2007)
    In her novel, which has made this year's International Man Booker shortlist, Lessing portrays a group of near-amphibious women who have no need of men, known as Squirts, as they are impregnated by the wind, wave or moon. But this is no feminist utopia: the women behave brutally, mutilating male babies before placing them on a rock for eagles to devour. The eagles turn out to be the men's allies, transporting the babies to the forest where they are suckled by does. Lessing reveals she was inspired by a scientific claim that "the primal human stock was probably female, and that males came along later, as a kind of cosmic afterthought".

    How Absolutely Boring.

    Probably appeals to the lesbians, though.

    It's sounds so science fiction, but when you watch Star Trek, Lost in Space, or any old sci-fi movies, they're using cell phones, which at that time seemed highly improbable, and now they're part of daily life. If something like this were to happen, I don't see it as just a lesbian thing. Straight women who are single or have a b/f or husband who can't get them pregnant may see this as an option. The weird part is that they'd only be having girls, which would change the natural rhythm of the population ever so slightly, unless it really caught on and then women would be the rulers of the universe.

    Women can already go to the Sperm Bank and pick "la crème de la crème" from the gene pool without ever having to know the name of the donor.

    Come to think of it Pirate Wench has a point... this is a big dick support forum...not likely many lesbians here to think is a real option...

    But it does kind of change the debate on homosexuals not being able to reproduce using their own DNA without using surrogate sperm.

    This allows them to use fem/fem DNA. No sperm or male needed.

    Yes, but they don't know who the father is. This girl they are creating is 100% theirs; their creation, if you will.

    Except this allows them to reproduce using their own connective tissue from their partner...not some foreign donor they don't know...

    I think that's a big difference, you can look at your child and see both of each other's features.

    I mentioned that because I read an in-depth article about how incredibly picky some of the sperm recipients were. While they didn't want the donor involved in any way, they wanted to know everything about his attributes, including voice, profession, education, family history, ....

    Some only wanted sperm from tall, athletic, Ivy League types who were also artistic and harbored no genetic predisposition to any known disease: in essence, perfection.

    Did a paper on this WAY back in the day..

    did you know most sperm banks are run by lesbians?

    Did you know that the very thing that women rebell against about being engineered to look for the best provider is evident in the sperm donor business?

    Comparitive pyschology and ethology states for the male species -their whole purpose in life is to get their DNA out there. Female species is to find the best provider, best DNA, survival, etc. All the women in our class railed against this.

    yet when you compare species it's true.

    Did the paper on sperm banks. read another article on a guy that volunteered and his experience.

    Did you know that if you were enrolled in a health studies class as a graduate student they classified you as a medical student?

    If you were over 6 feet tall your sperm was more likely to be used?

    Men with job descriptions of custodians, mechanics, were less likely to be used.

    That is women looked for more sperm donors that had advanced degrees or were pursuing them and were over 6 feet tall. Their selection was all about the best provider of DNA. ;)

    You're so gross, but the Ricky Nelson 'vahine' thing was a good catch. You got nose rings in your Lesbians cunts?

    Oh those things were posted and said about me, not things that I embrace...I just leave it up as a reminder about WHO is accusing me of being ignorant, the same special soul that calls me a cunt and any other reference to it. Mr. H and invisbleman had me laughing in tears on the spread a rumor about the person above you thread. The booger thing is about how we don't have a choice (more sarcasm, but hey you work with what you've got).

    Okay, sorry, but you see, if you 'weren't there', you could easily be suspected of being a 'hiding in plain sight' booger enthusiast...:lol:

    Wait, but if the sperm comes from their own bones, then there's no one to sue for child support.

    I imagine you would sue your female partner - who gave the bone marrow.

    yes but if that really were an option and the propagation of girls shot up, women would outnumber men...as they would only reproduce girls.

    Of course it is way more fun. But you could have this female Not_Punny clone created from your bone marrow.
