UK maintains persistent prohibition on puberty blockers for individuals under the age of 18
The United Kingdom has effectively implemented a de facto ban on prescribing puberty blockers to under-18s outside clinical trials, starting from 2024. This decision follows the Cass Review, which recommended more research before routine use due to limited evidence and concerns about safety and long-term impact, particularly on brain development and psychosocial outcomes.
The ban is not a formal legislative prohibition but a practical halt on prescribing outside research settings [1][3][5]. The ban was announced by the Department of Health and Social Care, citing independent expert advice from the Commission on Human Medicines that stated there is currently an unacceptable safety risk in the continued prescription of puberty blockers to children [5].
Timeline:
- April 2024: The final Cass Review was published, concluding that evidence for puberty blocker use in youths is limited and recommending caution and further study [1].
- Late 2024 to 2025: The planned start of the NHS clinical trial ("Pathways") was delayed from late 2024 to 2025. This trial is now the only route to access puberty blockers within NHS care for minors [1][5].
- Post-review 2024-2025: The NHS closed the original Gender Identity Development Service (GIDS) and opened smaller regional centers focused on holistic care emphasizing mental health and psychosocial support rather than hormone treatment [1][5].
- 2025: Health services in practice stopped issuing prescriptions for puberty blockers and gender-affirming hormones to new under-18 patients outside clinical research, despite no formal legislative ban [1].
Reasons for the ban/pause:
- The Cass Review found that existing evidence for the efficacy, safety, and long-term impact of puberty blockers was insufficient [1].
- Ethical concerns have been voiced around consent and control groups in the proposed studies, leading to controversy about how the research is conducted [2].
- Legal cases and NHS policy shifts have emphasized safeguarding and avoiding irreversible medical interventions without robust evidence, influencing clinical decision-making and referral processes [2][4].
Implications:
- Many trans youth report harm from the loss of access, including worsened mental health symptoms like anxiety and depression due to experiencing puberty changes they cannot medically pause [3].
- Families are left uncertain about how to support their children under current restrictions; some seek private or overseas treatments, raising concerns from social services and increasing safeguarding investigations [2].
- The NHS is focusing on "holistic care" with fewer referrals (around 30 per month vs. 5,000 previously), emphasizing psychosocial support over medical interventions [1].
- The extended pause and study requirement have sparked criticism from medical and trans advocacy groups internationally, charging that the UK is raising the bar for gender-affirming care higher than for other pediatric treatments and undermining established clinical best practices [2][5].
In summary, the UK has not legislated a formal ban but rather instituted a de facto ban on puberty blockers for under-18s by restricting access to clinical trials only, driven by concerns over insufficient evidence and safety, with profound mental health and care access impacts for transgender youth and their families [1][3][5]. This ban applies to new patients only, with NHS and private patients already receiving these medicines for gender dysphoria continuing to have access. The ban will be reviewed in 2027.

- The United Kingdom's de facto ban on prescribing puberty blockers to under-18s, starting from 2024, is driven by concerns over insufficient evidence and safety in light of the Cass Review's findings.
- The ban on routine use of puberty blockers has led to profound mental health and care access implications for transgender youth and their families, with many reporting worsened symptoms of anxiety and depression.
- Despite the de facto ban, the NHS continues to allow access to clinical trials involving puberty blockers for minors, marking a shift towards holistic care emphasizing mental health and psychosocial support.
- The UK's approach to gender-affirming care has sparked criticism both domestically and internationally, with opponents charging that the UK is raising the bar higher than for other pediatric treatments and undermining established clinical best practices.
