Sure.
But what does that prove?
If you take a female fetus and expose it to large amounts of androgens (male hormones) while it's in the womb, it will come out with a male-type brain. So it's still "biologically" a woman in the sense of chromosomes, but the brain is not like that of a normal woman.
And then it naturally follows that we should modify the body to be the same as the brain (because we can't modify the brain to change sex with our current technology, and it would probably be highly unethical to do so even if we could)

The exposure to these hormones would have to be the result of their own bodies for this to occur. And since this is a "female" body and not a "male" one, the glands would secrete estorogen. This would over ride a pre-pubecent child's "male" brain.
They had a tomboy and decided to mutilate the kid to make her "normal"
NO! Then it would come out with disfigured or ambiguous genitalia.
As usual you don't know what the hell you're talking about.
