It is being reported that the world's second known "pregnant man" is set to give birth to a baby boy next month.
Scott Moore and his partner, Thomas, were both born as girls. However, they underwent surgery and hormone treatments to change their sex.
While Scott, 30, is legally married to Thomas, he still has a female birth certificate.
"We know some people will criticise us, but we are blissfully happy and not ashamed," the Telegraph quoted Scott as saying.
The couple from California already has two adopted boys, Gregg, 12, and Logan, 10,
Both are the children of a former female partner of Thomas's.
"We want to show the world that trans-families can be healthy, loving and nurturing," said Thomas.
Scott originally born a girl called Jessica. He first realised he wanted to be a man when he hit puberty aged 11.
And started taking male hormones at the age of 16, with the consent of his parents. He also got his 36DDD chest removed.
"I opted not to have a penis because I couldn't afford it and I didn't think the results were very good - it had nothing to do with wanting children because back then I didn't think I'd ever have them," said Scott.
Thomas, who was originally born Laura began his transition aged 19.
He also started taking testosterone in 1999 and had his 44GG breasts removed at the UCSF medical centre in San Francisco in 2004.
Later that year he had a hysterectomy and a penis made out flesh from his thigh.
