Supporting evidence for providing gender-affirming treatments and procedures
Transgender people may seek any one of a number of gender-affirming interventions, including hormone therapy, surgery, facial hair removal, interventions for the modification of speech and communication, and behavioral adaptations such as genital tucking or packing, or chest binding. All of these procedures have been defined as medically necessary by the World Professional Association for Transgender Health. Lower quality research has found improvements in a range of psychosocial measures after gender-affirming treatments such as hormones or surgery.[2-5] Sevelius' Model of Gender Affirmation describes the ways in which denial of access to gender affirmation is associated with high risk behaviors and increased rates of HIV infection. Conversely, not all transgender people seek all interventions, and some may seek none. In contrast to past practices in which a set pathway involved a requirement of psychological assessment → hormones → genital surgery, the current standard of care is to allow each transgender person to seek only those interventions which they desire to affirm their own gender identity.
Gender-affirming hormone therapy is the primary medical intervention sought by transgender people. Such treatment allows the acquisition of secondary sex characteristics more aligned with an individual's gender identity.
A wide range of gender-affirming surgeries are available to transgender people. These include surgeries specific to gender affirmation, as well as procedures commonly performed in non-transgender populations.
Surgeries specific to transgender populations:
- Feminizing vaginoplasty
- Masculinizing phalloplasty / scrotoplasty
- Metoidioplasty (clitoral release/enlargement, may include urethral lengthening
