“puberty blockers have never been put through clinical trials for use in gender medicine, and are not licensed by their manufacturers for this purpose. Their main uses are to treat hormone-related conditions in adulthood, in particular endometriosis and prostate cancer, and to ‘chemically castrate’ sex offenders. The two studies that looked at what happened when they were used to delay puberty in animals suggested this caused defects in spatial memory and increased behaviours thought to be analogous to depression in humans.”

“It beggars belief that clinicians somehow learned to predict exactly which children would persist, exactly when they started using puberty blockers. Far more plausible is that puberty blockers, as well as blocking the physical changes that puberty brings, also blocked the developmental process whereby gender dysphoria often resolves”
