Healthcare for transgender people is in crisis. Many of the problems stem from bureaucracies within the health system, limiting conceptualizations of sex and gender, and the requirement for a diagnosis of ‘gender dysphoria’. This book presents a unique argument for full demedicalization of transness as a crucial step towards removing existing barriers to good healthcare.Resisting the current norm of separating sex and gender, it also argues for an understanding of them as necessarily interlinked and co-constructed. By elevating trans voices and experiences, this book offers a new perspective on transness, medicalization and research methodologies to help trans people, practitioners and policy makers better understand the barriers faced by trans people when seeking healthcare.
