Chris Birch's story of being turned gay by a stroke was featured during a segment Tuesday on CBS' The Doctors.

When Birch, 26, regained consciousness after suffering a stroke, he claimed his sexual orientation had been altered. He broke up with his fiancee, ditched his bank job, started a career as a hairdresser and eventually moved in with his 19-year-old boyfriend.

“I was gay when I woke up and I still am,” Birch told the UK's Daily Mail. “It sounds strange but when I came round I immediately felt different.”

“I wasn't interested in women any more. I was definitely gay. I had never been attracted to a man before – I'd never even had any gay friends.”

On The Doctors, Dr. Neil Martin, a neurosurgeon, backed Birch's claim, saying some stroke patients can become “hypersexual” or experience a “change in sexual orientation.”

“This is just one piece of evidence that suggests that the difference here is not some social personal preference,” Martin said. “The difference is a fundamental biological issue between individuals who are gay and who are straight. You're born that way.” (The video is embedded in the right panel of this page. Visit our video library for more videos.)
