It is also important to note that, under current guidelines, an adolescent must first undergo a comprehensive biopsychosocial mental health evaluation prior to starting pubertal suppression to ensure the clinical team has a comprehensive understanding of the adolescent’s mental health, that all potential gender supports that are needed are put into place, and that the adolescent and their guardians have a strong understanding of the medical intervention, its risks, side effects, and potential benefits. In addition, consent must be provided by parents or legal guardians, whereas adolescents themselves provide assent. Several studies have linked access to pubertal suppression, when indicated for gender dysphoria, to improved mental health outcomes (for example, van der Miesen and colleagues, Turban and colleagues, de Vries and colleagues, and Costa and colleagues).6-9
Later adolescence and gender-affirming hormones
Later in adolescence, transgender youth may be candidates for gender-affirming hormone treatment (for example, estrogen or testosterone) to induce pubertal changes that align with their gender identities. Once again, under current guidelines, a comprehensive mental health biopsychosocial evaluation must be conducted prior to initiation of these treatments. Part of this evaluation includes fertility counseling and consideration of fertility preservation (for example, oocyte or semen cryopreservation), given the potential for these medications to impact fertility. It also involves discussion of several of the physiologic changes from these medications that can be irreversible (for example, voice changes from testosterone are particularly difficult to reverse in the future). Tables of the physical changes from these medications, when they begin after starting, and when they generally reach their maximum are available in the Endocrine Society guidelines.2 The past endocrine society guidelines recommended not initiating gender-affirming hormones until age 16. The most recent guidelines note that there may be instances in which providers may consider starting them as early as age 13 (for example, to reduce risk of falling behind on bone density, or if a patient is having psychological distress related to their peers going through puberty while they are still in a prepubertal state). The latest World Professional Association for Transgender Health Standards of Care removed specific age cutoffs, highlighting the importance of a multidisciplinary team of mental health and hormone prescribing providers working together to understand the best course of action for a particular patient. As with pubertal suppression, several studies have linked access to gender-affirming hormones to improve mental health for adolescents with gender dysphoria (for example, Turban and colleagues, Chen and colleagues, de Vries and colleagues, Allen and colleagues, and Tordoff and colleagues).10-14
Gender-affirming surgeries
The vast majority of gender-affirming surgeries are not considered until adulthood. The most notable exception to this is masculinizing top surgery for trans masculine and nonbinary adolescents. As with all surgeries, this is a major decision, and requires agreement from a mental health provider, a medical provider, and the surgeon. Early research suggests such surgeries result in improved chest dysphoria and that regret rates appear to be low.15,16 While the latest World Professional Association for Transgender Health similarly removed strict age cutoffs for gender-affirming surgery, again noting the importance of individualized care, I suspect most will read this change in the context of the Endocrine Society guidelines and past WPATH guidelines that noted gender-affirming genital surgeries are not offered until adulthood (a rare exception perhaps being someone pursuing a gender-affirming vaginoplasty at say age 17 in the summer prior to college to avoid needing to take off from school for surgical recovery). Gender-affirming genital surgeries are generally much more involved surgeries with prolonged recovery times.
Given the substantial proportion of young people who openly identify as transgender,17 and the proliferation of misinformation, political rhetoric, and legislation that can impact gender-affirming care for adolescents with gender dysphoria,18 it is essential that providers have accurate, up-to-date information on what this care entails and how it is provided.
