A Retrospective Study of the Use of Gonadotropin-Releasing Hormone Analogs and Testosterone in Transgender Boys: Who, What, When, and for How Long?

A retrospective review of gender-affirming hormone therapy was conducted in 101 transgender boys followed in the pediatric endocrine clinic. Eighty-seven percent were postmenarchal at the initial visit. Of the 44% prescribed gonadotropin-releasing hormone analogs (GnRHas), insurance coverage was denied in 34% and an average of 4.5 months elapsed before treatment could be started in the remainder. Patients prescribed GnRHas were younger than those who were not, 13.7±2.1 versus 15.5±2.0 years, <0.001. Continued menstrual bleeding was reported by patients receiving testosterone alone at doses ranging from 50 to 200 mg every 2 weeks.
