"Clinicians should be aware that there is no evidence that sexual orientation can be altered through therapy, and that attempts to do so may be harmful. There is no empirical evidence adult homosexuality can be prevented if gender nonconforming children are influenced to be more gender conforming. Indeed, there is no medically valid basis for attempting to prevent homosexuality, which is not an illness. On the contrary, such efforts may encourage family rejection and undermine self-esteem, connectedness and caring, important protective factors against suicidal ideation and attempts. Given that there is no evidence that efforts to alter sexual orientation are effective, beneficial or necessary, and the possibility that they carry the risk of significant harm, such interventions are contraindicated."
