Pro to the question "Is Sexual Orientation Determined at Birth?"
Co-author of book Born Gay, which states that the genes involved in sexual orientation produce receptors in the brain which absorb male hormones released by the developing baby's testicles. It is thought that in gay men these receptors are less sensitive or are blocked. The absence of testosterone results in the brain developing certain female characteristics, including attraction to men.
