re: Transgender man gives birth to son

So this person use to be a man, but is now a chick who can get pregnant but can still grow facial hair? I am not judging I am just trying to figure this out. If you feel as if you are a chick and go through the surgery, why would you grow facial hair? That just blows the frick out of people's mind.. You have a dude face, facial hair, a dude haircut.. but pregnant.
