Thomas Beatie, who is legally male but decided to keep his female sex organs during chest reconstruction surgery and testosterone therapy, attracted worldwide headlines last year after revealing his pregnancy.

The 35-year-old gave birth to a baby girl in Oregon last July and on Tuesday celebrated the arrival of a second child, a baby boy, ABC News reported.

Mr Beatie was last year dubbed the 'pregnant man' after appearing on Oprah Winfrey's television talkshow to discuss his pregnancy.

"I 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," he said.

Mr Beatie revealed that he'd been "shocked" by the amount of publicity the couple had received, insisting they were just like any other family.

"We are a man, woman and child. It's ironic that we are so different but yet, we're just a family, just the same as anyone else," he said.

When asked why he made many people uneasy, he said, "I think that people are not used to seeing the image of a pregnant man.

"And it's causing a lot of people to think. … I used my female reproductive organs to become a father."
