What measurable differences are apparently related to homosexual versus heterosexual orientation in adult men?​

Quizplus · Accepted Answer

Research has found that there is a difference in the size of certain parts of the hypothalamus between homosexual and heterosexual men. In particular, the interstitial nucleus of the anterior hypothalamus (INAH-3) is typically larger in heterosexual men compared to homosexual men. The other options (testosterone levels, estrogen levels, and dendritic branching in the cerebral cortex) have not consistently been found to have measurable differences between homosexual and heterosexual men.
