Gays have children

Gays can't have children, therefore they can't marry!

Women might soon be able to produce sperm in a development that could allow lesbian couples to have their own biological daughters, according to a pioneering study published today.

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.

Although, there may be complications:
The research also raises questions about the long term genetic effects of creating sperm in this way which could have implications for the health and development of embryos and the children and adults they eventually become.

However the general consensus amongst scientists is that this is unlikely because embryos generally require genetic material from both a male and a female to develop normally.

I wish they'd, you know, quoted any such scientists. And all the other articles I looked at didn't say anything of the sort, but that may not mean much.
