Cass warns indefinite puberty blocker ban will harm more children than trial would

Dr Hilary Cass, author of the independent review that prompted the ban on puberty blockers for under-18s, stated on 22 June that more children will be harmed without a clinical trial than with one. Her review recommended trials only within research protocols, not an indefinite prohibition. The government made the ban permanent in December 2024, creating tension between Cass's original recommendation and the policy it triggered.
