Pregnant man on Oprah
Transsexual Thomas, 34, shocked the world when a picture was released showing his bearded face and growing belly.
The Hawaiian ex-lesbian kept his female reproductive organs and is nearly six months pregnant.
In clips from the show, which will be aired tomorrow, Thomas says: “I’m a person and I have the right to have my own biological child.”
The amazing revelations have been questioned by sceptics, but the Chicago-based talk show said Oprah had interviewed Thomas, his wife Nancy, their doctor and pals of the pair.
According to the clips from the show, Nancy tells how a hysterectomy left her unable to conceive.
Thomas said: “If Nancy could get pregnant, I wouldn’t be doing this.”
When he switched gender, Thomas had his breasts removed and began taking testosterone in a bid to grow facial hair.
But after keeping his female reproductive organs, Thomas fell pregnant through artificial insemination.
He expects to deliver a girl around July 3.
In an interview with an American magazine, he wrote: “Wanting to have a biological child is neither a male nor female desire, but a human desire.”
