In 2009, a research survey into mental health practitioners in the United Kingdom concluded that "a significant minority of mental health professionals are attempting to help lesbian, gay and bisexual clients to become heterosexual. Given lack of evidence for the efficacy of such treatments, this is likely to be unwise or even harmful." "Scientific American" reported on this: "One in 25 British psychiatrists and psychologists say they would be willing to help homosexual and bisexual patients try to convert to heterosexuality, even though there is no compelling scientific evidence a person can willfully become straight", and explained that 17% of those surveyed said they had tried to help reduce or suppress homosexual feelings, and 4% said they would try to help homosexual people convert to heterosexuality in the future.
