A UK clinical trial called Pathways, investigating puberty blockers for children, has been paused after the Medicines and Healthcare products Regulatory Agency (MHRA) raised concerns. The MHRA recommended a minimum age limit of 14 due to potential long-term biological harms. The trial sponsor, King's College London, will discuss these wellbeing concerns with the MHRA. The Department of Health and Social Care (DHSC) stated the trial will not proceed until the issues are resolved and expert advice deems it safe and necessary. The trial was initiated following a review that found weak evidence supporting the benefits of puberty blockers for young people with gender dysphoria. The DHSC emphasizes that the safety and wellbeing of children are the top priority.
