 The research literature on adolescent gender dysphoria, GD, does not provide enough evidence to adequately inform clinical decision making. Studies have shown an increase in the number of adolescents seeking help for GD, but the lack of whole population studies means that the prevalence of GD remains unknown. Additionally, the majority of studies are based on small samples, and many of them are limited by methodological flaws such as lack of control groups and inconsistent definitions of GD.
