Regulator blocks puberty blocker trial over child safety concerns

The MHRA blocked a government trial of puberty blockers for children, citing grave concerns about long-term biological harm and infertility risks. The regulator stated the trial risks putting children too young on a pathway they cannot consent to, with potential permanent bone damage and loss of brain function. This decision follows warnings from clinicians, campaigners, and the public about the irreversible consequences of such medical interventions for minors.
