Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, if he will commit to publishing the results of the Tavistock clinical trial into puberty blockers for children.

There have been at least two studies relating to puberty-suppressing hormones and the Tavistock clinic. The Early pubertal suppression in a carefully selected group of adolescents with gender identity disorders study, sponsored by University College London, published its findings in 2021. The Outcomes and Predictors of Outcome for Children and Young People Referred to UK Gender Identity Development Services: A longitudinal Investigation study, funded by the National Institute for Health and Care Research, was due to end in July 2025. We would expect the study findings to be published in a peer reviewed academic journal within 12 months of the completion of the study.

In addition, NHS England, in conjunction with the National Institute for Health and Care Research, is commissioning a data linkage study, which will provide different and separately valuable evidence to both understand the experience and outcomes of former patients of the Gender Identity Development Service and inform future National Health Service gender care. We would similarly expect the study findings to be published.
