Thomas Beatie stripped off for the cameras and bared his baby bump and also revealed pictures from his beauty queen days as a young woman.
However, the 34-year-old transsexual also told chat show host Oprah Winfrey that he feared for his own safety and admitted doctors had warned him his baby could be killed because of the revulsion at her birth.
Now six-months pregnant, Beatie walked onto the show with a grey cardigan stretched over the growing bump.
The TV chat show queen was filmed patting Beatie's bulging stomach during the hour long interview with his wife Nancy.
The 34-year-old transsexual was filmed for the show undergoing an ultrasound scan and preparing for the birth of their daughter.
Blurred images of the baby girl could clearly be seen as a smiling Beatie looked on.
Beatie said many doctors had refused to treat him and one warned him: "People would try to kill my baby because it is an abomination."
His appearance on US TV was part of a media blitz to knock down suggestions the pregnancy was a hoax.
As well as the Oprah show, Beatie also gave a detailed interview to People magazine.
The former beauty pageant queen, who conceived through artificial insemination, confessed many people saw him as a "freak".
He said some of his own family members had referred to the baby as "monster".
He accepts that not everyone will understand why he and his 45-year-old wife decided to have a child, which is due in July.
The couple, from Bend, Oregon, said they had already thought about the task of telling their child how she came into the world.
"When she's old enough, we'll sit her down and tell her everything," Beatie said.
"We will tell her how her parents love each other and love her very much.
"Our daughter is beating these incredible odds to get here - physical obstacles, social obstacles, everything.
"And in my dreams I dream the world will see her the way we do,as this amazing gift to us. As a miracle."
Beatie,who was born Tracy LaGondino in Hawaii, caused a worldwide sensation last week when he revealed the pregnancy in the gay magazine The Advocate.
But after neighbours in Oregon poured scorn on the pregnancy it was thought to be an elaborate hoax.
Beatie legally became a man after undergoing a sex change operation - but kept her female reproductive organs.
He told People magazine he decided to get pregnant after wife of five years Nancy had a hysterectomy.
"But who hires a surrogate if they are perfectly capable of carrying their own child?
"Why would I trust someone else when I know I'll do a better job of taking care of my body than anyone?
"And I'll be the father and Nancy will be the mother.
Beatie said he was afraid of how people would react when he gives birth.
"I want to make it easier for the next couple like us, but I'm afraid.
"Afraid of how people will react for our safety. I don't want to lose the life we have." Nancy, a mother of two, added: "We know this is a hard thing for some people to understand.
"But to us we're just a husband and wife who are having a baby."
