The research showed that when both heterosexual women and gay men are exposed to a testosterone derivative found in men's sweat, a region in the hypothalamus is activated. Sexual Hormones and the Brain: Twin studies additionally point to genetic explanations as the underlying force for same-sex partner preference in men and neuroticism , a personality trait that is comparable to anxiety. The INAH3 size of the homosexual men was apparently smaller than that of the heterosexual men, and larger than that of the heterosexual women, though neither difference quite reached statistical significance.
