Large Study Finds ‘Pretty Good Indication’ Of Genetic Link To Homosexuality


Researchers believe they are finding a genetic link to homosexuality in a study of almost 800 gay brothers.

A new, large study of almost 800 gay brothers is leading researchers to believe they have found a genetic link to homosexuality. Dr. Alan Sanders of the NorthShore University HealthSystem Research Institute in Evanston, Illinois, says his work "is not proof but it's a pretty good indication" of genes on the X chromosome influencing sexual orientation, according to the AP.

Dr. Robert Green, a medical geneticist at Harvard Medical School, called the new study "intriguing but not in any way conclusive."

The work was published Monday by the journal Psychological Medicine. The National Institutes of Health paid for the research.

Study participant Dr. Chad Zawitz, a Chicago physician, called the research "a giant step forward" toward answering scientific questions about homosexuality and helping reduce the stigma gays often face.

Being gay "is sort of like having certain eye color or skin color — it's just who you are," Zawitz said. "Most heterosexuals I know didn't choose to be heterosexual. It's puzzling to me why people don't understand."

The study appears to be accepting new applicants.
