Psychological evaluation and medical treatment of transgender youth in an interdisciplinary "Gender Management Service" (GeMS) in a major pediatric center.

In 2007, an interdisciplinary clinic for children and adolescents with disorders of sex development (DSD) or gender identity disorder (GID) opened in a major pediatric center. Psychometric evaluation and endocrine treatment via pubertal suppressive therapy and administration of cross-sex steroid hormones was offered to carefully selected patients according to effective protocols used in Holland. Hembree et al.'s (2009) Guidelines for Endocrine Treatment of Transsexual Persons published by the Endocrine Society endorsed these methods. A description of the clinic's protocol and general patient demographics are provided, along with treatment philosophy and goals.
