The document discusses research on the INAH-3 nucleus, located in the anterior hypothalamus. Studies have found INAH-3 to be twice as large in men compared to women. Additionally, INAH-3 was found to be larger in heterosexual men compared to homosexual men or transgender women. The size of INAH-3 appears to correlate with sexual orientation and gender identity.
