The answer
Evidence from precocious-puberty care is relevant to known drug effects. It does not by itself show that blocking normally timed puberty improves gender dysphoria or that the full blocker-to-hormone pathway has a favorable long-term risk-benefit balance.
The comparison also has to account for what happens next. In pediatric gender medicine, suppression may be followed by cross-sex hormones, with unresolved questions about bone development, fertility, sexual function, and long-term psychosocial outcomes.
