Thomas Beatie - who shot to fame in 2008 when he became the world's first 'pregnant man' - has announced plans to have a fourth child. But this time his partner, Amber Nicholas, will be the one carrying the baby.
Thomas, 39, was born a woman and had a sex change when he was in his early twenties. He gave birth to three children - Jenson, Susan and Austin - with his ex-wife Nancy Beatie, but the couple have since separated.
In an interview with US news magazine show Inside Edition, Thomas discussed his plans to expand his family with new partner Amber.
Medical issues prevent Thomas from giving birth again, so his girlfriend Amber will carry the baby - but because Thomas is younger, she will be using one of his eggs. The couple hope to use the same sperm donor as Thomas used with his three older children.
"I actually really like the idea of her carrying my child," Thomas explains in the interview. He also is keen to stress that in day-to-day life theirs is a typical family, despite their unusual situation.
