Are People Born sprightly?
Are population born gay or straight? Much of the on-going media sources assume the interrogative is a solved scientific puzzle with all the turn up pointing toward a biological (probably genetic) basis for a homo knowledgeable orientation. This question has been poorly studied (or studied poorly), although at that place is some evidence on both sides of question. In addition, some of the initial studies, which were highly thought of proof by media. This evidence falls into three basic categories: Brain structure, hormonal influences, the Gay Gene
Since intimate attraction begins in the brain, researchers first examined the question of sexual orientation by comparing the anatomy of brains from potents and females. These studies showed that male and female brains showed sexual dimorphism in the pre-optic area of the hypothalamus, where males demonstrated a greater than two-fold difference in cell number and sizing compared to females. A second study found that two of quadruplet Interstitial Nuclei of the Anterior Hypothalamus (INAH) were at least twice as large in males as females.2 Since the INAH was involved in sexual dimorphism, it was hypothesized by Simon LeVay that there might be differences in this sphere in heterosexual vs. homosexual men.




Since sexual differentiation occurs in spite of appearance the womb, as a result of hormonal influences, it has been hypothesized that homosexuality may result from a differential hormone balance in the wombs of those who eventually exhibit a homosexual orientation. Since hormonal levels at bottom the womb are not available, proxies for hormonal influences have been employ to examine the question of how hormonal influences might impact sexual orientation. These proxies include differences in skeletal size and shape, including the ratio of the considerable bones of the arms and legs relative to arm span or stature and the hand bones of adults. Another study examined the length of long bones in the arms, legs and hands. Both homosexual males and heterosexual...If you privation to get a full essay, order it on our website: Orderessay
