Did your brother make you gay?

By RealJock Staff

Scientists say you can "blame" (or thank!) your big brother for your homosexuality.

What do you think of the study's findings? We're doing an informal poll to see if RealJocks validate the research. Tell us about your brothers (or lack thereof) and what you think of the research.

Take the survey.

A study reported in Science News magazine in June shows that the more older male siblings a man has, the more likely he is to be gay.

Even if your older brothers were all off at college when you were born, you're more likely to be gay if you have biological older brothers (step, half and adoptive brothers don't increase your homosexual tendencies), psychologist Anthony F. Bogaert of Brock University in St. Catharines, Ontario, told Science News.

Bogaert told Science News that, regardless of the amount of time spent with older brothers during childhood, the number of biological older brothers correlated with the propensity for homosexuality.

The reason for this birth-order link is unknown. Bogaert postulates in Science News that a mother's immune system may treat male fetuses as foreign bodies, attacking them with antibodies that alter sex-related brain development, Bogaert suggests in Science News.
