The world's first pregnant man has been photographed showing off his post-baby body.
Thomas Beatie, 37, who has had three children in three years, is pictured playing in a pool with his youngest son, Jenson.
Jenson was born naturally on July 25 last year.
His toned stomach suggests he has worked hard to get his body back post pregnancy and birth.
As well as baby Jenson, Mr Beatie, who lives in Arizona with his wife Nancy, has a two-year-old son called Austin, and a three-year-old daughter, Susan.
Thomas was born Tracy Lagondino, in Hawaii in 1974, but began having testosterone injections in his twenties to give him male characteristics.
He had a mastectomy in 2002 and legally became a man, but as he chose to keep his vagina, uterus and other female sexual organs he was able to bear children.
His wife Nancy, 47, had a hysterectomy when she was younger and so was unable to conceive - she did, however, breastfeed all three of the couple's children.
