I consider it my business to speak out against the sterilization of gay, autistic, and sexually abused youth. I consider it my business to oppose eugenics experiments on children.
"Eugenics"? I hope you are using hyperbole. The real complex of issue of trans people does not involve keeping them from having children (i.e. eugenics), but treating them in a fair and humane fashion.
If you are not using hyperbole, then I find it hard to take your view seriously, since it appears to be based by delusions.
Cross sex hormones administered during puberty almost always result in the child being sterile. Testosterone destroys ova, especially if taken before menarche. Estrogen taken before spermarche can prevent maturation, and make male children sterile. Puberty blockers taken early in puberty for more than a very short period of time prevent sexual maturation - the prevent the penis from elongating, prevent the scrotum from dropping further from the body, prevent the enlargement and increased elasticity of the uterus, and prevent the maturation of the mammary ducts in breasts resulting in an inability to produce milk even if the individual doesn't have a mastectomy.
The suite of drugs given to youth experiencing dysphoria frequently result in them being sterile.
They're not reversible, they're not safe, and they're certainly not solution. Children should be allowed to fully mature out of their juvenile state before being turned into permanent medical patients.
