Are M to F transgenders still able to become hard? An produce sperm? I wonder just what changes go on down there while this change is going on?
In male to female reassignment surgery, the erectile tissues [the structures that cause an erection] and testicles are removed, and skin of the penis and scrotum are 'inverted' in side the body to create a functional vagina. Orgasm can still be achieved, but there's generally no ejaculate and certainly no sperm produced.
