The UK sets a minimum age of 11 for children to be recruited into a clinical trial of puberty-blocking drugs, according to reporting from the BBC and RTE. The trial is intended to study the use of puberty blockers for gender-questioning children. Both outlets report that eligibility is limited by age, with participants needing to be at least 11 years old. RTE also notes that some campaigners argue the trial should be stopped entirely, raising concerns about potential harm to young people. The BBC focuses on the new age threshold as the key change, describing it as a requirement for entry into the study. Together, the coverage highlights that the trial is continuing under agreed recruitment criteria, while public debate persists around the appropriateness and safety of puberty blockers for children. The reports do not provide additional clinical or procedural details beyond the minimum age requirement and the existence of ongoing controversy.
