Another of your failures, Bingo boy. A female having her breasts lopped off doesn't change gender.It's in the link you dumb bitch.But here, I'll quote it for the lazy and the incapable trailer park crowd.
Gender identity - NHS England Digital
Gender identity is a way to describe a person’s innate sense of their own gender, whether male, female, or non-binary, which may not correspond to the sex registered at birth.
For many, but not all people, the sex they were registered at birth is the same as their current gender.
A simple concept you Bingo's have difficulty understanding.
