BMA reverses stance on Cass review after internal reevaluation

The British Medical Association (BMA) has withdrawn its opposition to the Cass review, a major assessment of NHS gender identity services for young people. The decision follows a new internal evaluation by 12 union members, reversing the BMA’s earlier stance against the review’s recommendations.

The Cass review, led by Dr. Hilary Cass, examined care for children and adolescents with gender dysphoria. It found that routine medical interventions, such as sex hormones for under-18s, lacked sufficient evidence. The report also concluded that patients had been poorly served by weak research and that gender services were 'built on shaky foundations'.

Initially, the BMA council voted to oppose the review’s 32 recommendations, calling them 'unsubstantiated'. The union had refused to endorse the findings and criticised their implementation. Now, after further assessment, the BMA has shifted its position. Professor David Strain, chair of the BMA’s board of science, described the review process as constructive. He noted that clinicians with differing views had engaged respectfully and that the evidence was carefully examined. Strain also highlighted consistent respect for the data and the ethical challenges involved.

The BMA’s change in stance means the Cass review’s recommendations may now face fewer obstacles. The review’s warnings about weak evidence and flawed service structures remain central to the debate. Clinicians and policymakers will need to address these findings as they shape future gender identity care.
