Quizplus · Accepted Answer

Several studies have found differences in the size or structure of the hypothalamus between homosexual and heterosexual individuals. Specifically, one study found that homosexual men had a smaller hypothalamic region called the suprachiasmatic nucleus (SCN) than heterosexual men. The SCN is involved in regulating circadian rhythms and is also implicated in sexual behavior. However, it should be noted that these findings are not consistent across all studies and the causes and implications of such differences are not fully understood.
