Freud believed treatment of homosexuality was not successful because the individual does not want to give up their homosexual identity because it brings them pleasure. He used psychoanalysis and hypnotic suggestion as treatments, but showed little success. It was through this that Freud arrived at the conclusion that homosexuality was "nothing to be ashamed of, no vice, no degradation, it cannot be classified as an illness, but a variation of sexual function". He further stated that psychoanalysts "should not promise to abolish homosexuality and make normal heterosexuality take its place", as he had concluded in his own practice that attempts to change homosexual orientations were likely to be unsuccessful. While Freud himself may have come to a more accepting view of homosexuality, his legacy in the field of psychoanalysis, especially in the United States viewed homosexuality as negative, abnormal and caused by family and developmental issues. It was these views that significantly impacted the rationale for putting homosexuality in the first and second publications of the American Psychiatric Association's DSM, conceptualizing it as a mental disorder and further stigmatizing homosexuality in society.
