Helen Webberley fact-checks Dr Hilary Cass's recent radio interview, examining the claims made and their clinical context.22 February 2026
Dr Hilary Cass's appearance on RNZ National generated significant discussion in gender healthcare circles. As someone working clinically with trans and non-binary patients, I wanted to offer a careful, detailed review of what was said and how it stands up against the evidence.
This analysis explores the key claims made during the interview, looks at what the research actually shows, and considers the broader clinical context that sometimes gets lost in shorter broadcast segments. My aim is to help readers understand not just what was said, but what it means for the young people and families navigating gender healthcare.
