It never fails to amaze me that the learned doctors are willing to administer the opposite sex hormone and mutilate the child before trying the same sex hormones to see if they can realign the person with his whole, natural body. Apparently they think the mind is not affected by the hormonal imbalance, and that imagining one would be happier as the opposite sex is a rational decision in a person with an obvious hormonal imbalance.
At 12, I'd say that the hormones aren't really in full swing yet. Shouldn't he have to "give it a shot" before they whack anything off?
