How did 'The Pregnant Man' get pregnant?

Answer 1

The "Pregnant Man" was born female. He went through a Sexual Reassignment Surgery to remove his breasts (if he had some), then they constructed a small male genitalia and called him a man. He kept his female reproductive system so he and his wife could conceive children. They are legally married, because he is legally a man.

There was another story about a "pregnant man" who was born with his twin brother inside him. Just thought you might like to know. Did you read that thing about a baby having a foot removed from his brain?
The pregnant man is a transsexual man, meaning he was born with female parts instead of male parts. He still had lady parts, and thus all he had to do was stop taking male hormones and let himself become fertile again.
