orientation done by Alan Bell, Martin Weinberg, and Sue Hammersmith showed some stunning results. The three researchers interviewed 979 gay men and lesbian women and 477 heterosexual men and women in the San Francisco area. Their results basically concluded that, “…all the environmental explanations are inadequate and are not supported by the data.” And also, “Sexual orientation seems to be determined before adolescence.” Their findings leans more towards the idea that sexual orientation is mainly determined by biological factors. “Nature, not nurture, is the main factor involved in sexual orientation.” This statement is made to assist the idea that a person does not get to choose whether they will be homosexual or heterosexual because they’re born into it. It also means that it is not our surroundings and our environment that channels us into our sexual orientation. Rather, it is our biological make up that decides which route we will take. There have been many researches conducted to support this statement. One of these researches is Simon LeVay’s study on the human brain. In his 1991 study, LeVay, a neuroscientist in La Jolla, California, found that the hypothalamus, the section of the brain that controls sexual activity, was less than half the size in gay men than in the heterosexuals. It also appears that the hypothalamic cells of the homosexual male were more similar to those of women compared to those of heterosexual males. Also in 1991, Michael Bailey and Richard Pillard did a research on sexual orientation, but their research was based on twins. They recruited heterosexuals and homosexuals that had twins, either identical or non-identical. They found that within 56 gay men who had an identical twin brother, 52% of them were both gay. But among 54 gay men with a non-identical twin brother, only 22% of them were both gay. Two years later, this study was done...
