Thomas Beatie, a married man who used to be a woman, has told America's ABC News that after giving birth to Susan on June 29 he did not go back on the male hormone testosterone so he could have another baby.
"I feel good," he told ABC News' Barbara Walters. "I had my checkups ... And everything is right on track."
Beatie, who lives with his wife Nancy in Bend, Oregon, said the baby is due on June 12.
Beatie was born a woman but underwent hormone therapy before he was legally declared a man.
He had a mastectomy but kept his female reproductive organs when he underwent a sex change in the late 1990s.
He and Nancy decided they wanted to start a family and he underwent artificial insemination late last year.
Walters said on her television talkshow, "The View," that Beatie had revealed his second pregnancy to her during an interview for a d0cumentary to air on U.S. television Friday night.
Prior to her birth, he released a photo showing his bearded face and pregnant belly. It sparked a worldwide media frenzy.
