Hormone Therapy in Transgender Men

Abstract

Currently, transgender medicine is not a strong part of the medical curriculum, although a large number of transgender persons will search for some kind of gender-affirming care. As psychopathology is clearly reduced in transgender persons after the initiation of hormone therapy, we believe all endocrinologists should become familiar with endocrinological care for transgender persons. In transgender men, testosterone therapy is initiated, aimed at achieving cisgender male reference values of serum testosterone in order to induce virilization. Although gender-affirming hormonal therapy with testosterone is considered safe, endocrinological follow-up is advised in all transgender people receiving gender-affirming hormonal care and will be discussed in this chapter for transgender men.
