The couple became pregnant using donor sperm and Thomas's eggs, through artificial insemination, after relocating in 2005 to Bend, Ore., where they operate a T-shirting printing business.

Their baby girl is Thomas's first child. "The only thing different about me is that I can't breastfeed my baby. But a lot of mothers don't,"

Beatie says the baby was not delivered via C-section. He intends to publish a book about his experience this fall.
