Who said two women couldn't have a baby without a man and this is an argument against DADT?

The new approach, which could allow infertile women to have genetically related babies, does not constitute cloning, since any resulting child would have genes from a father as well as a mother. But it is similar enough to cloning to be illegal in California and perhaps in other states where broadly worded anti-cloning legislation has been passed, said Jamie Grifo, the New York University doctor who is leading the experiments.
The work breaks new ethical ground by being the first to mix significant amounts of DNA from two women's eggs into a single egg. That means any resulting child will have two genetic mothers -- although one woman contributes vastly more than the other and so will clearly be the dominant biological mother.
Grifo described the novel approach here yesterday to an electrified audience at the annual meeting of the American Society for Reproductive Medicine. Experts said the research offers the latest evidence that in the fast-paced field of reproductive medicine, the line between promising therapeutic techniques and ethically questionable genetic manipulations is getting blurrier every day.
The goal, Grifo emphasized, is to provide an alternative to infertile women. Today, the only options for these women are adoption or creation of a baby through in vitro fertilization using an egg donated by another woman.
Many cases of female infertility are caused by an inability to produce eggs. But many others, including among most older premenopausal women, involve eggs that for one reason or another are defective. The method used by the New York team is based on scientists' growing recognition that in many of these cases the problem is not with the DNA inside a woman's eggs but with the fluid, called cytoplasm, that surrounds that DNA. That suggests that their DNA could be used to make a baby if it could be drenched in healthier cytoplasm.
In the new work, the researchers removed the main mass of DNA, called the nucleus, from an infertile woman's egg and injected it into a healthy donor's egg whose nucleus had already been removed. When the reconstituted egg was mixed with sperm in the laboratory, it began to grow into an embryo that the doctors then placed in the infertile woman's womb.

The sperm will to be 'borrowed' but both women would have the genes of the two women involved.
