Anthony Bogaert

Bogaert is known for studying multiple subjects related to human sexuality, including asexuality.^[1][2] He has also published studies examining the relationship between the number of brothers a man has and his sexual orientation. These studies have concluded that the more older brothers a man has, the more likely he is to be gay, and that this effect is due to prenatal factors, not environmental ones.^[3][4][5][6] In his early career, Bogaert worked with J. Philippe Rushton to publish a paper hypothesizing biological evidence of Race differences.^[7] This paper was critiqued two years later by Michael Lynn who stated:

First, they did not explain why natural selection would have favored different reproductive strategies for different races. Second, their data on race differences are of questionable validity because their literature review was selective and their original analyses were based on self-reports. Third, they provided no evidence that these race differences had significant effects on reproduction or that sexual restraint is a K characteristic. Finally, they did not adequately rule out environmental explanations for their data.^[8]
