It "might be said" but that makes no sense to anyone who knew firmly what their gender identity was from early childhood. The norm is around 4 years of age. It also makes no sense given that dysphoria does disappear for a portion of patients irrespective of which hormones they're on. As well as for those on puberty blockers. The entire point of puberty blockers is allow for delaying the decision on going on hormones or surgery as long as needed for the patient to be able to make an informed choice.

And of course a lot of the kids given hormones will end up getting surgery, because their dysphoria is highly unlikely to resolve itself with or without hormones and for those whose dysphoria does not resolve surgery will be the best option for many - hence the very low regret rates.

And hence the drive to get puberty blockers to delay the need to decide on either.

You're buying into a hysteria founded on ignoring the actual and immoral harm being inflicted on trans youth by those seeking to deny them care in order to try to pretend they mostly don't exist. It's at best deeply misguided, at worst deeply bigoted.
