We have been using puberty blockers for a long time. They were around when I was prepubescent. They’re established medicine, and doctors deem whatever the side effects are to be worth helping the children’s mental and physical health.

All medicine is like this. Very little medication has no side effects at all. Yet we give children medicine all the time. Because it does more good than harm.

Who decides if it does more good than harm? Medical professionals. Not laymen on the Internet.
