If a young boy has a feminine throw he may be homosexual. Also if he has a soft or high voice this would be another detection that one would be homosexual. There have been many conclusions and statements as to what causes homosexuality. These are the traits that normally are classed with someone who is homosexual. The popular argument in todays society is that homosexuality is something that is inborn, genetically linked to an enlarged gland in the brain or due to a particular chromosome. This would prove that it is natural, and that it is luck of the draw whether one is homosexual. There have been many studies done to prove this theory, but due to a lack of evidence it has remained just that, a theory. Homosexuality, contrary to popular beliefs, is not inborn and has yet to be proven.Dr. Simon LeVay, a neuroscientist at the Salk institute of Biological Studies in San Diego, conducted a series of autopsies in order to seek out the reason for sexual orientation. In 1991, he conducted autopsies on forty-one people in search of an answer (Winslow 2). Among these cadavers, nineteen were allegedly homosexual men, sixteen allegedly heterosexual and six allegedly heterosexual women. His study was primarily centered towards a group of neurons in the hypothalamus structure. This structure is called the interstitial nuclei of the anterior hypothalamus, or otherwise known as the INAH3 (Dallas 111). His reports showed that he found a portion of the brain that he believed regulated to sexual behavior in men. The gland he discovered was twice as large in men assumed to be homosexuals as it was in those who were homosexual(Winslow 2). In the same year that Dr. LeVay performed his research, there was a pair of researchers out for the same answer to homosexuality, that it is inborn. Dr. Michael Bailey, a psychologist at Northwesten University and psychiatrist Dr. Richard Pillard of Boston University School of Medicine experimented with twins compari...
