Last month, the UK’s four-year-long review of medical interventions for transgender youth was published. The Cass Review, named after Hilary Cass, a retired pediatrician appointed by the National Health Service to lead the effort, found that “there is not a reliable evidence base” for gender-affirming medicine. As a result, the report concludes, trans minors should generally not be able to access hormone blockers or hormone replacement therapy (HRT) and instead should seek psychotherapy.
