A US man who was born a woman before undergoing gender realignment surgery has given birth to a baby girl, US media reported Thursday.

Thomas Beatie, who is legally male but decided to keep his female sex organs during chest reconstruction surgery and testosterone therapy, attracted worldwide attention in April after revealing his pregnancy.

The 34-year-old gave birth to a baby girl at a hospital in Bend, Oregon, ABC News reported, without providing further details.

Beatie, who sports a beard, was dubbed the 'pregnant man' after appearing on Oprah Winfrey's television talkshow to discuss his pregnancy.

"I feel it's not a male or female desire to have a child. It's a human need. I'm a person and I have the right to have a biological child," Beatie told the chat show queen.

Beatie's unusual situation first became public when he wrote an article, Labor of Love, in the leading US gay magazine The Advocate in March.

"To our neighbors, my wife, Nancy, and I don't appear in the least unusual," he wrote, explaining that his wife was unable to have a child after undergoing a hysterectomy. So he chose to become pregnant by artificial insemination, he said.

"Our situation sparks legal, political, and social unknowns," Beatie wrote, adding the couple had experienced opposition from health care professionals, friends and family.

One doctor refused to treat the couple, after consulting an ethics board.

"How does it feel to be a pregnant man? Incredible. Despite the fact that my belly is growing with a new life inside me, I am stable and confident being the man that I am," Beatie wrote.
