Anthony Bogaert, PhD Biography

Associate Professor at Brock University
Pro to the question "Is Sexual Orientation Determined at Birth?"

“I demonstrate that the number of biological older brothers, including those not reared with the participant (but not the number of nonbiological older brothers), increases the probability of homosexuality in men. These results provide evidence that a prenatal mechanism(s), and not social and/or rearing factors, affects men’s sexual orientation development.” (accessed July 11, 2006)
