Thomas Beatie, the female-to-male transgender who caused controversy in 2007 when he became pregnant, has separated from his wife of nine years, according to People magazine.

Beatie, who has had three children with wife Nancy, announced the separation during a taping of CBS' "The Doctors."

"Like all marriages, we have our ups and downs, and we're going through a rough patch right now. At the moment, we're separated," Beatie said on the show, according to People magazine.

Also during the taping, Beatie revealed that he had the final female-to-male gender reassignment surgery, People reports.

"Nancy hasn't seen the new me yet," Beatie, 38, says.

Beatie, who was born female in 1974 and named Tracy Lagondino, had sex-reassignment surgery in 2002 and legally changed from female to male in Hawaii. But Beatie had never undergone "bottom" surgery, known as phalloplasty, to create an artificial penis, until now. He also left his female reproductive organs in place and said the decision to bear children came after his wife, Nancy, found out she could not.

Beatie first made headlines in 2007 when he appeared in photos, bearded with a pregnant belly. He was then known as "the world's first pregnant man."

Beatie's three children, daughter Susan and sons Austin and Jensen, were all born between June 2008 and July 2010 through artificial insemination using donor sperm.

In October, Beatie, Nancy, and their three children appeared on another episode of "The Doctors" in which Beatie revealed he was considering a hysterectomy.

The new episode of "The Doctors" airs Monday, May 7.
