For nearly a hundred years the Tavistock and Portman NHS Foundation Trust has been at the forefront of exploring young minds. This series, with exclusive access to the Trust, goes behind the doors at the Tavistock for the first time. The Tavistock’s gender service is the country’s only NHS-run gender clinic for children and young people with gender dysphoria – a profound distress caused by feeling they’ve been born into the wrong body. With transgender issues and stories rarely out of the news, the gender specialists have seen a 100% rise in referrals, but still understand very little about why children feel this way. Led by Consultant Psychologist Dr Polly Carmichael, the gender team have to decide whether or not to prescribe controversial drugs to children and teens.
