Question to the Department of Health and Social Care:

To ask His Majesty's Government whether they have commissioned research to establish the rate at which patients treated at adult Gender Dysphoria Clinics subsequently detransition, express regret about their transition, or discontinue treatment.

The Cass Review concluded that the percentage of people who subsequently detransition following medical intervention remains unknown due to the lack of long-term follow-up studies.

In response to the recommendations of the Cass Review and the Operational and Delivery Review of Adult Gender Services, NHS England plans to consult on a service specification for a detransition pathway later this year, an element of which will be proposals for building the evidence through data collection, formal research and clinical audit.
