Rethinking Youth Gender Medicine with Dr Louise Irvine
18 June 2026
With Dr Louise Irvine
UK
Dr Louise Irvine, a General Practitioner and co-chair of the Clinical Advisory Network on Sex and Gender (CAN-SG), joins the podcast ahead of CAN-SG's London conference on rethinking youth gender medicine. She reviews the evidence failures that allowed a clinical field to outpace its own research base, recaps the WellBN clinic investigation, and examines how NHS institutions became captured by gender-identity ideology. The episode draws on the Cass Review's findings and looks ahead to the clinical and research reforms that could put youth gender medicine on a sound footing.
Dr Louise Irvine is a General Practitioner and GP trainer based in the UK, and co-chair of the Clinical Advisory Network on Sex and Gender (CAN-SG). CAN-SG brings together clinicians concerned that healthcare institutions adopted gender-identity frameworks without adequate evidential scrutiny. Recorded ahead of CAN-SG's two-day London conference on 5 and 6 July, this episode outlines what the conference aims to achieve and why a clinical reckoning is now overdue. The conference, titled Rethinking Youth Gender Medicine, is designed to address the field comprehensively: aetiology, evidence quality, ethics, cultural pressures, and what sound clinical practice should actually look like. Irvine argues that for too long, clinicians who raised concerns were marginalised, and that the field accumulated a body of practice that ran far ahead of any robust evidence base. The conference is intended to provide a professional space where those questions can finally be examined systematically. A significant part of the conversation concerns the WellBN clinic investigation. WellBN emerged among the new regional gender services that followed the Cass Review's recommendation to move away from the single centralised model that had existed at the Tavistock. Irvine recaps what the investigation found and what it reveals about the risk of reproducing old approaches under new institutional names. The episode makes clear that structural reorganisation alone does not resolve the underlying clinical and governance failures the Cass Review documented. Irvine also reflects on how NHS institutions became captured by gender-identity ideology in the first place. She traces the role of ideological assumptions in shaping which research questions were permitted, the barriers encountered by those who questioned the dominant framework, and the way clinical governance mechanisms failed until sustained external scrutiny — most consequentially the independent Cass Review — forced the reckoning that is still under way. This dynamic, in which a professional consensus hardens before the evidence warrants it, is central to understanding what went wrong. The episode takes up the concept of tooth fairy science — research that investigates the properties of an intervention while never questioning whether the foundational premise holds. Helen Joyce's framing is discussed as a way of understanding how a thin evidential base was presented in the language of settled medicine. The NHS England puberty blocker trial is addressed in this context, with attention to what rigorous, ethically designed research in this area would actually require. The conversation closes on what research is genuinely needed going forward: longitudinal follow-up of young people who went through the gender clinic pathway, meaningful data linkage across health records, and honest appraisal of outcomes. Irvine represents a cohort of clinicians who believe the field can be rebuilt on firmer foundations, and that the path forward depends on the kind of clinical transparency and evidential rigour the CAN-SG conference is designed to model.
