They noted a decrease in suicidal ideation among youth who have access to gender-affirming care and comparable levels of depression to cisgender peers among socially transitioned pre-pubertal youth. In its 2017 guideline on treating those with gender dysphoria, it recommends puberty blockers be started when the child has started puberty (Tanner Stage 2 for breast or genital development) and cross-sex hormones be started at 16, though they note "there may be compelling reasons to initiate sex hormone treatment prior to the age of 16 years in some adolescents with GD/gender incongruence". They recommend a multidisciplinary team of medical and mental health professionals manage the treatment for those under 18. They also recommend "monitoring clinical pubertal development every 3 to 6 months and laboratory parameters every 6 to 12 months during sex hormone treatment".A review published in Child and Adolescent Mental Health found that puberty blockers are fully reversible, and that they are associated with such positive outcomes as decreased suicidality in adulthood, improved affect and psychological functioning, and improved social life.More rigorous studies are needed to assess the effectiveness, safety, and long-term benefits and risks of hormonal and surgical treatments. For instance, a 2020 Cochrane review found insufficient evidence to determine whether feminizing hormones were safe or effective. Several studies have found significant long-term psychological and psychiatric pathology after surgical treatments.In 2021, a review published in Plastic And Reconstructive Surgery found that less than 1% of people who undergo gender-affirming surgery regret the decision.
This suggests that the distress of gender dysphoria is mostly not caused by the cross-gender identity itself, but by difficulties encountered from social disapproval by ones culture. Overall, it is unclear whether or not gender dysphoria persists in cultures with third gender categories. Classification as a disorder
The psychiatric diagnosis of gender identity disorder (now gender dysphoria) was introduced in DSM-III in 1980. Arlene Istar Lev and Deborah Rudacille have characterized the addition as a political maneuver to re-stigmatize homosexuality. (Homosexuality was declassified as a mental disorder in the DSM-II in 1974.) By contrast, Kenneth Zucker and Robert Spitzer argue that gender identity disorder was included in DSM-III because it "met the generally accepted criteria used by the framers of DSM-III for inclusion." Some researchers, including Spitzer and Paul J. Fink, contend that the behaviors and experiences seen in transsexualism are abnormal and constitute a dysfunction. The American Psychiatric Association stated that gender nonconformity is not the same thing as gender dysphoria, and that "gender nonconformity is not in itself a mental disorder. The critical element of gender dysphoria is the presence of clinically significant distress associated with the condition. "Individuals with gender dysphoria may or may not regard their own cross-gender feelings and behaviors as a disorder. Advantages and disadvantages exist to classifying gender dysphoria as a disorder.
