I have to confirm this -- but I am going to say that one's sex (not gender WTF) cannot be changed because the development of the body, if allowed to grow to maturity, is 'hard coded' in the genes. You can pump a male full of estrogen and etc, but it would just result in a chemically imbalanced male.

I can't even imagine how you can synthetically force a male to have a uterus, but you can (I guess) implant one. However I don't think it will be functional, and furthermore I think the body will reject it regardless.

HOWEVER if we pretended that it would be possible, the result would be either a very close genetic copy to the parent or just a close genetic variation of the 'male's' family gene pool.
