No. Psychologists, psychiatrists and other mental health professionals agree that homosexuality is not an illness, mental disorder or emotional problem. Much objective scientific research over the past 35 years shows us that homosexual orientation, in and of itself, is not associated with emotional of social problems.
Homosexuality was thought to be a mental illness in the past because mental health professionals and society had biased information about homosexuality since most studies only involved lesbians and gay men in therapy. when researchers examined data about gay people who were not in therapy, the idea that homosexuality was a mental illness was found to be untrue.
In 1973 the American Psychiatric Association confirmed the importance of the new research by removing the term ‘homosexuality’ from the official manual that list all mental and emotional disorders. In 1975 the American Psychological Association passed a resolution supporting this action. Both associations urge all mental health professionals to help dispel the stigma of mental illness that some people still associate with homosexual orientation. Since original declassification of homosexuality as a mental disorder, this decision has subsequently been reaffirmed by additional research findings and both associations.
