Two-mother conception.

Will lesbian couples ever be able to conceive a child together? If researchers in the United Kingdom are successful, they might.

Scientists from the U.K.'s Newcastle University were recently given government approval to create a human embryo with genetic material from two mothers. The research, intended to prevent the transmission of genetic defects, does not involve human cloning, they said. It would use normal in vitro fertilization procedures, but before the sperm and egg fused, the components of a nucleus from a human embryo created by a man and a woman would be implanted into the unfertilized egg.
