Does an older brother increase a younger brother's chances of being gay?

Filed under: Just For Moms, Development/Milestones: Babies

According to researchers at Brock University, St. Catharines, Canada, if a boy has several older brothers his chances of becoming a homosexual will increase from 3% to 5%. The affect does not apply to step-brothers or adopted brothers, only blood brothers can have the psychological impact on a younger brother to influence the outcome of his sexuality. The research team gives credit to a biological basis for being gay; the link must come through the mother and then through her older sons. While there have been previous similar studies, this is the first one to eliminate social and environmental factors.

This study seems a bit hooey to me. Sure it's interesting, it stops you for a moment and makes you think, "Hmmm." But does this mean that my two year-old's chances of being gay have increased by 2% simply because he happens to have an older brother? I couldn't care less if he does grow up and announce that he is gay at some point, he's my son and I will adore him regardless. What about you? What do you think?
