Reply #24: The past cases where that's happened have ended badly

Brains are gendered. You can't turn a male brain into a female one, no matter how early you start hormones, it was all decided in the womb. Kids who were subject to gender assignment/reassignment as the result of ambiguous genitals or traumatic injury grow up much like transpeople, feeling they aren't at home in their own bodies, only with the added complication of deception by parents and medical people and anger when it's found out. Some of them pursue surgical correction later. Some of them kill themselves, as happened in the most famous case, which involved a boy who was reassigned and raised as a girl after his penis was destroyed in a botched circumsicion. I don't think I've ever heard of a case that worked out at all well, in terms of the child growing up happy and comfortable with their assigned gender.

Anyhow, nothing could make him a functional female. A surgically created vagina is more convincing than a surgically created penis, and with hormones he'd be able to grow breasts and all, but he'll never have really functional (either reproductively or sexually- normally the latter is less of an issue but the erogenous tissue of the penis is generally used to create a vagina in MTF reassignments and in this case that's a non-option) sex organs of either sex. If he can't have anything near functionality in any case, he's almost certainly better off with a body that will mirror his self-perception
