This review identifies gaps in knowledge, and provides recommendations foci for future research. Recent findings Increasing numbers of gender nonconforming youth are presenting for care. Clinically useful information for predicting individual psychosexual development pathways is lacking. Transgender youth are at high risk for poor medical and psychosocial outcomes. Longitudinal data examining the impact of early social transition and medical interventions are sparse. Existing tools to understand gender identity and quantify gender dysphoria need to be reconfigured to study a more diverse cohort of transgender individuals. Increasingly, biomedical data are beginning to change the trajectory of scientific investigation. Summary Extensive research is needed to improve understanding of gender dysphoria, and transgender experience, particularly among youth. Recommendations include identification of predictors of persistence of gender dysphoria from childhood into adolescence, and a thorough investigation into the impact of interventions for transgender youth. Finally, examining the social environments of transgender youth is critical for the development of appropriate interventions necessary to improve the lives of transgender people.
