Puberty blockers and hormones are different things, that's why they have different names. Puberty blockers do not cause infertility or a lack of sexual function. So 96% of children go on to become adults that choose to take hormones because they made the right decision going on puberty blockers. There is a good reason why children should have access to puberty blockers, and to not suffer through a puberty that isn't in line with their gender; it's so they don't kill themselves.
Another is to consider that while over 96% of children given puberty blockers proceed to cross-sex hormones, those treated with watchful waiting desist in around 85% of cases.
This suggests that puberty blockers are much more likely to cement gender dysphoria, rather than treat it.
Furthermore, there is no evidence to show that not being prescribed puberty blockers causes gender dysphoric children to kill themselves.
"There is a significant inverse association between treatment with pubertal suppression during adolescence and lifetime suicidal ideation among transgender adults who ever wanted this treatment. These results align with past literature, suggesting that pubertal suppression for transgender adolescents who want this treatment is associated with favorable mental health outcomes."
