Psychiatry hasn't helped society in this issue at all, and I for one doubt that the practice ever could.
Within the field of psychiatry, especially reperative therapy as outlined by NARTH and other organization, has helped many homosexuals to a large degree with their unwanted homosexual attractions. You see, that's the key from what I have read. If a homosexual is tired of their lifestyle that significantly improves their odds of becoming heterosexual through therapy. Remember, there
are many documented studies of lesbians coming back and totally leaving the lesbian lifestyle.
