UK based Sundance Films is moving ahead with plans to produce a documentary on the life of Thomas Beatie, the world's first transgender man to give birth. The hour-long documentary, titled Pregnant Man, tells the story of Beatie and his family.

Born Tracy Lagondino, a former Miss Hawaii Teen USA beauty pageant finalist, Tracy transgendered to Thomas in his early twenties. He confessed on The Oprah Winfrey Show that his childhood was troubled.

Beatie legally married his wife Nancy in 2003, a mother of two divorcee. He decided to get pregnant after learning that Nancy was unable to bear another child due to a hysterectomy. Beatie had retained his reproductive sexual organs when he transgendered to a man.

Speaking to Oprah Winfrey, he defended his right to have a child. β€œI feel it's not a male or female desire to have a child,” Beatie said. β€œIt's a human need. I'm a person and I have the right to have a biological child.”

The couple became pregnant through artificial insemination and gave birth to a healthy baby girl at an Oregon hospital on June 29th.

September Films has already sold United Kingdom rights to the BBC's Channel 4. United States distribution has not been released.
