An “ex-gay” therapist promises he can fix gay people's brains, leaving behind no evidence of their former sexual orientation.

Appearing on Daystar's Joni Table Talk, Texas-based Dr. Jerry Mungadze, originally from Zimbabwe, claimed that his technique for altering a person from gay to straight, which he calls Right Brain Therapy, literally changes the brain's structure.

“The good news is, at least with the people that I've seen, not a lot of people, when the healing takes place those areas of the brain that were showing the homosexuality show heterosexuality,” he said on the show. “I have had several people who when I looked at them I couldn't tell the difference between a heterosexual who never was homosexual and them, which means the brain is able to go back and fire the way it is supposed to be, which is an argument against the whole idea of someone was born that way.” (The video is embedded on this page.

In a blog post, Wayne Besen of Truth Wins Out, offered Mungadze $10,000 to “rewire” his brain.

“I won't hesitate to say the truth: Dr. Mungadze is a sleaze and a con artist who is ripping off vulnerable and desperate people,” Besen wrote. “He is committing consumer fraud, misleading his clients, and profiting from their pain. I will give him $10,000 if he can scientifically prove his scam therapy works.”
