All that told me was that if you castrated a mouse on day one of it's birt and injected it with hormones, it would alter. If you left the testes in, however, it would remain masculine.
All you "answer" did was prove my point.
Unless "She" was more of an "it" (which a statement like "She's still biologically a girl" would disagree with) then hormones alone would do nothing, even at an early age.
Thank you for your post, sorry it took so long, went out of town.
