<unk>  is the medical aspect of gender transitioning, that is, modifying one's sex characteristics to better suit one's gender identity. It can consist of hormone therapy to modify secondary sex characteristics, sex reassignment surgery to alter primary sex characteristics, and other procedures altering appearance, such as permanent hair removal for trans women. In appropriately evaluated cases of severe gender dysphoria,<unk>  is often the best when standards of care are followed. There is academic concern over the low quality of the evidence supporting the efficacy of<unk>  as treatment for gender dysphoria, but more robust studies are impractical to carry out; as well, there exists a broad clinical consensus, supplementing the academic research, that supports the effectiveness in terms of subjective improvement of<unk>  in appropriately selected patients. Treatment of gender dysphoria does not involve attempting to correct the patient's gender identity, but to help the patient adapt. Major health organizations in the United States and UK have issued affirmative statements supporting<unk>  as comprising medically necessary treatments in certain appropriately evaluated cases.
