While LeVay's study did find a difference in brain size between homosexual and heterosexual men, the fact that many of the homosexual participants had died from HIV complications introduces a confounding variable. Therefore, it is difficult to determine whether the difference in brain size is a result of sexual orientation or the effects of the disease. Additionally, it is important to note that LeVay's findings have not been consistently replicated, and that sexual orientation is likely determined by a complex interaction of genetic, environmental, and biological factors.
