This is not true...
A: Puberty blockers on their own do not affect fertility. When blockers are stopped, puberty will resume along with normal sexual function and fertility. But if a teen decides to go directly from blockers to cross-sex hormones, which can affect fertility, patients can risk not having mature eggs or sperm to preserve, depending on their age when they started treatment.
For this reason, medical experts and organizations like the Endocrine Society recommend that transgender youth are "fully informed of fertility preservation options prior to initiating puberty-delaying treatment."
No, you are not leaving them alone. If it weren't for you (pl), they would be figuring themselves out on their own, making informed decisions as adults when they are able to consent and fully comprehend the ramifications of these procedures and the lifelong commitment to treatment it take$. The "doctors" and medical professionals doing this to CHILDREN should have their licenses revoked, their parents prosecuted for child abuse, and people like you shunned by polite society for encouraging and promoting this psychological contagion.
Children need to be kept from you polluting their minds, not "educating" them into the nonsense you were brainwashed by.
That is leaving them alone, not you people encouraging them with your ideological perversions and for-profit pseudo-science.
Fix yourselves while you still can.
