Thomas Beatie, the world's first transgender man to give birth, is expecting a third child any day now, first reported.

Beatie gave birth to his first child, daughter Susan, on June 29, 2008 in an Oregon hospital. Austin followed a year later.

β€œHe's in full-term now and passed his due date,” an unnamed source close to the family said.

Beatie's 2008 announcement that he was pregnant in gay monthly The Advocate drew controversy and stirred emotions about Beatie's claimed masculinity. He defended his right to have a child on The Oprah Winfrey Show, saying: β€œI 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, a beauty queen in his former life, had sex reassignment surgery in 2002, but opted to keep his reproductive sexual organs. He then legally changed his birth certificate from Tracy to Thomas and married Nancy, a mother of two divorcee, in 2003. The couple decided he should get pregnant after learning that Nancy was unable to bear another child due to a hysterectomy.

The couple says they do not know the sex of the baby and want to be surprised.
