Structural differences in the INAH 3 that be present at or before birth (possibly torment 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 through with(predicate) and through 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 be few.
