Brian Structures and Sexual Orientation

Males and Females have the same structures within the brain, though particular structures disagree in sizing of it of it, one structure, the Third Inistitial Nucleus of the anterior Hypothalamus (INAH 3) is primarily larger in the male population (LeVay, 1991) turn out in work force who atomic number 18 paederastic. LeVay (1991) has shown that homosexual males have convertible surface structure of the INAH 3 to wo workforce. The similarity in INAH 3 size between homosexual men and straightaway women maybe a cause of femininity as Gorman (1994) stated that homosexuality is said to follow femininity in males. human men have an attraction toward other men, sound as heterosexual women have an attraction toward men, with similar INAH 3 size do these female structures within the male brain make the one-on-one a homosexual or do these morphological differences add up utility(prenominal) to homosexuality? Structural differences in the INAH 3 that argon present at or bef ore birth (possibly cod to prenatal environment) should be able to be explained by biology (LeVay, 2003) while differences in structure size that occur secondary (after the individual recognises himself as homosexual) should be able to be explained finished social experiences (Harrison, Everall and Catalan, 1994). This paper will discuss homosexuality in reference to males only, unless stated otherwise, as studies into female homosexuality are few.

Biology shows differences in brain structures between men and women, size differences in structures, in particular the INAH. The INAH is found in the digest of the brain, down the stairs the hypothalamus and is composed of four regions INAH 1 through to 4, homosexual men have sim! ilar INAH 3 structural size to heterosexual women (Gorman, 1994) while homosexual women have similar structures to heterosexual men (LeVay, 1991). It has been suggested that sexual orientation may be hardwired (Harrison et al, 1994) as roughly homosexual men say that they were born...
