The medical 'management' of individuals with atypical sex characteristics, or intersex variations, has been under scrutiny since the beginnings of intersex activism in the 1990s. This article explores a history of intersex surgeries in Britain and the interaction with medical and popular discourses around 'sex-change' between 1930 and 1955. A focus on this period in Britain helps to critically elaborate on debates in intersex scholarship; provides historical context for the introduction of approaches and protocols based on John Money and colleagues' work in the USA in the mid-century; and analyses a long history of tension and intersection between trans and intersex experiences, treatments, politics and popular representations that continue into the present.
