Doctors pump children with damaging irreversible puberty blockers

Puberty blockers are GnRH analogues, a class of medication used for decades in children with precocious puberty, where the goal is exactly the same: to pause a process before it runs ahead of where a child is. When the medication stops, puberty resumes. That is what reversible means, and it is not in serious dispute. The word "damaging" does a lot of work in that sentence without doing any of the evidence: the honest picture is that research is ongoing, that clinicians weigh benefit against risk for every individual child, and that this is exactly what careful medicine looks like in any speciality. What is not in dispute is the cost of getting the timing wrong. Puberty does not pause while a family searches for certainty, and every month of an unwanted one leaves physical changes that no amount of later treatment can fully undo. Families frightened away from an early clinical conversation by the word "irreversible" are not being kept safe: they are being handed a door that closes a little more with each passing month.
