In 1973, the American Psychiatric Association issued an advisory stating that homosexuality should no longer be considered a mental disorder. [6] Consequently, homosexuality was removed from the Diagnostic Statistical Manual (DSM), which is the diagnostic reference for all North American health and social service professionals. In 1990, the World Health Organization (WHO) approved the 10th edition of the International Statistical Classification of Diseases and Related Health Problems (ICD-10), which recognized that “sexual orientation (heterosexual, bisexual or homosexual) by itself is not to be regarded as a disorder.”[7] In 2007, the American Academy of Family Physicians rejected the use of “conversion” therapy for LGBT persons.[8]
