A Spanish trans man who was due to give birth to twin boys in September has miscarried.

Ruben Noe Coronado, 25, who was born a woman, had stopped his course of hormone treatments in order to fall pregnant via artificial insemination. He had not yet had surgery to remove his female reproductive organs.

He decided to carry the babies himself after his wife was told she could no longer conceive. The couple are planning to try again, which means further interruption of his transisiton.

Coronado told El Mundo: “I started having a few problems this week, there were days when my belly was a little low and I was surprised. I went to the doctor and I had to undergo a surgical scrapping.”

American trans man Thomas Beatie gave birth to his second child on Tuesday. Born female, he has undergone some gender realignment surgery but, like Coronado, had kept his female reproductive organs.

Last year Spain passed a law allowing those with a “a sexual identity problem” to officially change their sexual status without gender realignment surgery.
