Little Is Known About the Effects of Puberty Blockers
February 25, 2021
(The Economist) – All drugs offer a mix of harms and benefits. But despite their popularity, the effects of puberty blockers remain unclear. Because they are not licensed for gender medicine, drug firms have done no trials. Record-keeping in many clinics is poor. A 2018 review by researchers at the University of Melbourne described the evidence for their use as “low-quality”. In December British judges likewise flagged the lack of a “firm evidence base” when ruling that children were unlikely to be able to give meaningful consent to taking them. Britain’s National Health Service recently withdrew a claim, still made elsewhere, that their effects are “fully reversible”. The studies that do exist are at once weak and worrying.
