Eligibility for gender affirming surgery often involves a comprehensive evaluation. Candidates typically need to have a diagnosis of gender dysphoria, as defined by the DSM-5, and must meet specific criteria, which may include: - Persistent, well-documented gender dysphoria. - Capacity to make a fully informed decision and to consent for treatment. - Age of majority in a given country (age 18 in many places). - If significant medical or mental health concerns are present, they must be reasonably well controlled. - Typically, one year of continuous hormone therapy and living in a gender role congruent with one’s identity (for certain surgeries).
