Puberty blockers

Puberty blockers are the same class of drugs used for chemical castration in prostate cancer — GnRH agonists that shut down sex hormones and stop the physical changes of puberty: breast growth, voice change, facial hair, and the rest. (NCI · Cleveland Clinic · FDA Lupron label)

Unethical and ideological doctors give them to children in distress about their sex, so those children will not go through puberty. The idea is that growing into a man or a woman would be too traumatic, and would make it harder for them to pass as the opposite sex. That is the published clinical rationale, not a caricature. (Endocrine Society 2017 · HHS 2025 review)

They are given at the onset of puberty, around the time pubic hair first starts to grow. The technical term for when clinics recommend starting them is Tanner Stage 2. (Endocrine Society 2017)

Starting in the Netherlands in the 1990s, these drugs were first given to children with severe and prolonged gender dysphoria that had begun at a young age. (HHS 2025 · Sweden Socialstyrelsen)

The drug most often used is a GnRH analogue such as Lupron. It was first approved for advanced prostate cancer in men as a chemical alternative to physical castration. (NCI · FDA label)

In some jurisdictions, hormonal “chemical castration” is also used on sex offenders before they are eligible for parole. (Statutes often name medroxyprogesterone or equivalents; GnRH agonists are used in some clinical settings.) (Alabama code · AP) The ACLU of Alabama called mandatory chemical castration of sex offenders cruel and unusual punishment and opposed it. (WSFA · Vox) In our upside-down world, that same ACLU has repeatedly sued to keep these same kinds of drugs flowing to children — what amounts to chemically castrating them — calling it life-saving care. (Brandt v. Rutledge · ACLU press release)

GnRH analogues have other uses, such as for endometriosis in women. In that case, the FDA advises women not to take the drug for longer than six months because the side effects — including bone loss — are so severe. (FDA endometriosis label)

Let that sink in. Only six months for women with an actual medical need — but clinics give these drugs to children for years through puberty, and keep them on the drugs when cross-sex hormones begin. (Endocrine Society 2017 · clinical follow-up · GnRHa consortium · Hopkins dosing)

There are no good long-term trials showing this helps children. Systematic reviews and evidence assessments in Finland (COHERE), Sweden (SBU · Socialstyrelsen), England (Cass Review), Canada (McMaster systematic review), and the U.S. (HHS 2025) have all found the evidence for benefit is weak or unproven, while the harms to bone density, fertility, and sexual development are serious.

Puberty blockers combined with cross-sex hormones commonly cause permanent infertility — especially when started early in puberty. (Human Reproduction · HHS 2025 · Cass)

We already know the better path. In older clinic studies — before these drugs were given to dysphoric kids — most children’s distress about being male or female went away after natural puberty. Puberty was the cure. Now clinics block the cure. (Steensma et al. · Singh & Zucker · Cass)

Children cannot consent to this. They do not have the ability or maturity to understand what they are signing up for. Gender doctors know this, but keep harming these children anyway. See the WPATH Files (excerpts) and the systematic reviews above for their own admissions.
