Can Sexual Orientation Be Successfully Changed?

PRO (yes)

The Catholic Medical Association stated in its 2005 online publication, "Homosexuality and Hope":

"Reviews of treatment for unwanted same-sex attractions show that it is as successful as treatment for similar psychological problems: about 30% experience a freedom from symptoms and another 30% experience improvement...

Those who claim that change of sexual orientation is impossible usually define change as total and permanent freedom from all homosexual behavior, fantasy, or attraction in a person who had previously been homosexual in behavior and attraction...

For a Catholic with same sex attraction, the goal of therapy should be freedom to live chastely according to one's state in life. Some of those who have struggled with same-sex attractions believe that they are called to a celibate life. They should not be made to feel that they have failed to achieve freedom because they do not experience desires for the other sex. Others wish to marry and have children. There is every reason to hope that many will be able, in time, to achieve this goal. They should not, however, be encouraged to rush into marriage since there is ample evidence that marriage is not a cure for same-sex attractions. With the power of grace, the sacraments, support from the community, and an experienced therapist, a determined individual should be able to achieve the inner freedom promised by Christ."

Joseph Nicolosi, PhD, President of NARTH, et al., wrote in a 2000 study published in Psychological Reports, that:

"We present the results of a survey of 882 dissatisfied homosexual people whom we queried about their beliefs regarding conversion therapy and the possibility of change in sexual orientation...

Of the 882 participants, 726 of them reported that they had received conversion therapy from a professional therapist or a pastoral counselor...

Before treatment or change, only 2.2% of the participants perceived themselves as exclusively or almost entirely heterosexual, whereas after treatment or change, 34.3% perceived themselves as exclusively or almost entirely heterosexual...

As a group, the participants reported large and statistically significant reductions in the frequency of their homosexual thoughts and fantasies that they attributed to conversion therapy or self-help. They also reported large improvements in their psychological, interpersonal, and spiritual well-being."

Robert L. Spitzer, MD, Professor of Biometric Research at Columbia University, wrote in his study "Can Some Gay Men and Lesbians Change their Sexual Orientation? 200 Participants Reporting a Change from Homosexual to Heterosexual Orientation," published in the Oct. 2003 issue of Archives of Sexual Behavior:

"This study tested the hypothesis that some individuals whose sexual orientation is predominantly homosexual can, with some form of reparative therapy, become predominantly heterosexual...

The majority of participants gave reports of change from a predominantly or exclusively homosexual orientation before therapy to a predominantly or exclusively heterosexual orientation in the past year. Reports of complete change were uncommon...

Thus, there is evidence that change in sexual orientation following some form of reparative therapy does occur in some gay men and lesbians."

[Editor's Note: Dr. Spitzer retracted this study in Apr. 2012 in a letter to Ken Zucker, the editor of Archives of Sexual Behavior, quoted by the Truth Wins Out website in its Apr. 25, 2012 report "Exclusive: Dr. Robert Spitzer Apologizes to Gay Community for Infamous 'Ex-Gay' Study":

"I offered several (unconvincing) reasons why it was reasonable to assume that the subject's reports of change were credible and not self-deception or outright lying. But the simple fact is that there was no way to determine if the subject's accounts of change were valid.

I believe I owe the gay community an apology for my study making unproven claims of the efficacy of reparative therapy. I also apologize to any gay person who wasted time and energy undergoing some form of reparative therapy because they believed that I had proven that reparative therapy works with some 'highly motivated' individuals."]

US Surgeon General David Satcher, MD, PhD, wrote in a July 9, 2001 article "The Surgeon General's Call To Action To Promote Sexual Health and Responsible Sexual Behavior":

"Sexual orientation is usually determined by adolescence, if not earlier, and there is no valid scientific evidence that sexual orientation can be changed."

The American Psychological Association wrote in its online article, "Answers to Your Questions About Sexual Orientation and Homosexuality" (accessed Dec. 7, 2004):

"The reality is that homosexuality is not an illness. It does not require treatment and is not changeable."

The American Psychiatric Association Commission on Psychotherapy by Psychiatrists wrote in a 2000 article, published in the American Journal of Psychiatry:

"[A]necdotal reports of 'cures' are counterbalanced by anecdotal claims of psychological harm. In the last four decades, 'reparative' therapists have not produced any rigorous scientific research to substantiate their claims of cure.

'Reparative' therapy literature also tends to overstate the treatment's accomplishments while neglecting any potential risks to patients."

The Human Rights Campaign, in their 1999 publication "Mission Impossible: Why Reparative Therapy and Ex-Gay Ministries Fail," stated:

"The psychological, medical and psychiatric establishments agree that sexual orientation cannot be changed, and that so-called 'reparative therapy' aimed at altering gay peoples' orientations does not work and may, in fact, be harmful...

The purveyors of 'reparative therapy' are well outside mainstream research and thinking in the psycho-therapeutic world."
