Cori Cohn
Detransitioner and legislative campaigner
Cori Cohn underwent genital surgery in 1994, aged nineteen — years before British waiting lists and long before Tavistock became a household name. Now in his early fifties and identifying as neither male nor female, he has become one of America's most prominent detransitioner voices. His testimony offers a sobering long-view as the NHS rebuilds its gender services after the Cass Review.
In 1994, at the age of nineteen, Cori Cohn underwent genital surgery — a decision made at a time when the concept of gender identity had barely entered public consciousness and American gender clinics operated with little of the oversight that reformers now argue was always necessary. In the episode 30 Years After Transition, Cori Cohn Speaks Out (#32), he told hosts Stella O'Malley, Mia Hughes and Dr Bret Alderman that he now considers himself neither male nor female, and that the certainty he felt as a teenager dissolved across the decades that followed.
Since coming to terms with his regret, Cohn has channelled his experience into sustained advocacy, testifying before multiple US state legislatures in support of measures to restrict medical transition for minors. His case rests not on ideology but on the distance between what he was told to expect and what he has actually lived — a distance, he argues, that was never adequately put to him or his family before surgery.
For British listeners, Cohn's account carries particular weight. The Cass Review established that thousands of young people passed through the Tavistock GIDS without rigorous assessment and that long-term outcomes were almost never tracked. Cohn is precisely the kind of witness that failure produced: an adult surveying three decades of consequence from an irrevocable procedure undertaken in adolescence. His testimony makes viscerally concrete what systematic follow-up neglect looks like in a single human life.
As NHS England builds new regional gender services on an evidence-based model, voices like Cohn's are shaping the clinical and legislative debate on both sides of the Atlantic. His refusal to fit a tidy narrative — neither fully returned to his birth sex nor at peace with transition — makes him one of the more honest and unsettling witnesses in a conversation that rarely welcomes ambiguity.
