Homosexuality is a field of scientific research.
In recognition of the scientific evidence, the American Psychiatric Association removed homosexuality from the DSM in 1973, stating that "homosexuality per se implies no impairment in judgment, stability, reliability, or general social or vocational capabilities
Although early writers also used the adjective homosexual to refer to any single-sex context (such as an all-girls school), today the term is used exclusively in reference to sexual attraction, activity, and orientation
