Summary The development of gender identity in children from around the age of 3 years is described. Wishes for transgender identity are distinguished from gender-atypical behaviour. Reasons for the recent rise in transgender referrals in the early teen years are discussed. The now widely used protocol developed by the Amsterdam group for assessing transgender children and young people and, where appropriate, offering them puberty blockers, cross-sex hormones and sex reassignment surgery is described. Evidence for the effectiveness of this approach is considered. The competence of young people to give consent to these procedures is discussed. Finally, proposals are made for topics urgently requiring further research.
