Additional Study Information: We know that puberty is a major time of change! Adolescents develop new decision-making skills and independence. It is possible that some of these changes are due to the hormonal changes during puberty. One of the ways we treat transgender and gender non-conforming teens is to suppress or "block" puberty. We know that this is a safe thing to do for teens because we use it in people who start puberty too early (precocious puberty) and in people who are born very small in order to prolong their growth potential. We are doing this study to continue to understand the impact of this therapy on adolescent cognition and psychosocial functioning when it is used for gender dysphoria.
