Thomas Beatie, a transsexual who made headlines for giving birth to three children as a legally recognized male, has spilt from his wife of three years.

The 38-year-old recently underwent the final stages of his female-to-male gender reassignment surgery after separating from his wife Nancy, he revealed on the TV Show The Doctors.

Like all marriages, we have our ups and downs, and we're going through a rough patch right now, he said.

Nancy had two children from a previous relationship, but when she couldn't bear anymore, Beatie stepped in. He stopped taking his hormone medication and became fertilized through artificial insemination (using a sperm donor.)

Beatie had not had phalloplasty surgery, to create an artificial penis, and therefore was able to give birth.

By this stage Beatie had legally become recognized as a male, making him the world's first known man to give birth, the Global Post reported.

Beatie made headlines in 2008 when he had his first child. No one really understood how it was possible for him to give birth.

I stopped taking my bimonthly testosterone injections, Beatie said. It had been roughly eight years since I had my last menstrual cycle, so this wasn't a decision that I took lightly. My body regulated itself after about four months, and I didn't have to take any exogenous estrogen, progesterone, or fertility drugs to aid my pregnancy, Beatie told The Advocate, during the time.

Beatie's three children, daughter Susan and sons Austin and Jensen, were all born between June 2008 and July 2010. If Nancy could get pregnant, I wouldn't be doing this, Beatie told People Magazine. Who hires a surrogate if they are perfectly capable of carrying their own child?

But now, having spilt from wife Beatie has undergone the final stage of his surgery and will not be able to give birth in the future.

Before becoming a trans-sexual, Beatie was a model and finalist in Miss Hawaii Teen USA. He started to dress like a man in his 20s. His sex change has been gradual. First taking hormones and having his breasts removed, before undergoing sex reassignment surgery in 2012.
