Gender is a fast-evolving and topical field which is often the centre of attention in the media and in public policy debates.

Gender diverse young people are not only developing new ways of describing gender, but they are also shaping what is required of clinical interventions. Emerging cultural, social and clinical trends, such as increases in referrals, shifts in sex ratio and diversification in gender identification, illustrate that gender diverse individuals are not a homogeneous group. How do evolving concepts of gender impact the clinical care of gender diverse young people presenting to specialist gender clinics today?
