I don't think screwing around with their hormones and macabre surgery is the answer. I think the answer is intensive psychiatric treatment. For these "doctors" to be recommending and giving out hormones to children who do not have a genetic disorder and who have healthy and normally functioning body parts . . . that is sooo unethical.
Therapy is normal for these kids, don't worry about it.
What you want is for someone to stand them naked before a mirror and say see, you're a boy. That's great unles their mind says that's not true.
The true sex organ, the true gender organ, is the brain. Over time that, not the body, tells you who you are.
