You are wrong. Puberty blockers do not cause infertility or lack of sexual function. Your statements are incorrect and incongruent with established medical knowledge and advice. Also, trans is an adjective, not a plural noun.
There's no good reason why these children can't experience their normal, untarnished puberty, and defer the decision to medically trans themselves to later on, in adulthood, when they are older and wiser.
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."
