What do medical experts say about homosexuality?

The vast majority of modern medical and scientific experts agree that:
  • Homosexuality is not a disorder. It is a normal variation of human sexuality.
  • Sexual orientation cannot be changed. An attempt to do so may be harmful.

The normalcy of homosexuality has been generally accepted by the greater scientific community for over 30 years - the American Psychiatric Association removed homosexuality as a mental disorder from the Diagnostic and Statistical Manual of Mental Disorders (DSM) in 1973.
