Essay about Correlations between Biology and Male Homosexuality

According to Frank Worthen, “Homosexuality is a learned behavior which is influenced by a number of factors like a disrupted family or maybe lack of unconditional love, a failure to identify with the same sex parent. Later these problems can result in a search for love and acceptance, envy of the same or the opposite sex, a life controlled by various fears and feelings of isolation. One thing that does seem clear, homosexuality is brought about by a multitude of root

Following the declassification of homosexuality as a disease in 1973, a variety of methods have been made in attempts to help members of the LGBT community become

A pattern emerges where the scholarly literature exploring this topic is largely focused on males. Reason being is that it appears that males are the sex who are predominantly homosexual in their orientation (LeVay & Baldwin, 2012). However, the sensitivity within the discourse of sexual orientation arises when it is debated upon whether one 's sexual preference is innate at birth, hence a force of nature or biology, or if it is a result of culture, nurture or environmental factors (Emmanuele et al., 2010). Furthermore, an experimental design will be proposed to further examine this topic. Comparing the three chosen studies, it is evident that a biological and endocrinological perspective does account for sexual orientation (Kraemer et al., 2006; Manning et al., 2007; Miller et al., 2008). Of the studies that currently exist on this topic, data shows that prenatal testosterone levels are indicative of sexual orientation (Kraemer et al., 2006; Manning et al., 2007; Miller et al., 2008). This paper addresses a topic that is relevant in today 's society; a topic that has, for the most part, been written off as having any scientific roots (Emmanuele et al., 2010). This paper counters that belief and in reading this essay, it will be evident that biology and endocrinology have a much stronger influence on sexual orientation than previously thought.

A different possibility is that prenatal hormone levels influence the developing fetus (Levay, 2011). According to the prenatal hormonal theory of homosexuality, some male fetuses are exposed to too little testosterone. Similarly, some female fetuses are exposed to too much testosterone. These differences, in turn, can impact sexual orientation (Mustanski, Chivers, & Bailey, 2002). Regardless, homosexuality is not caused by hormone imbalances in adulthood; the hormone levels of most gay men and lesbians are within the normal range (Banks & Gartrell, 1995).

He contradicted the argument that homosexual behaviour is related to genetic, hormonal or biological disorder. To abolish these views, the author mentions that ‘no school of medicine, medical journal or professional organization has ever recognized such claims (p. 2) - at least at the time he wrote the article in 1994.

It is a fair assumption to say that America is approaching a new age in understanding and accepting the many variations of human sexual orientation. More same-sex couples have fostered children than ever before in our nation 's history. Institutions such as military and professional sports have (slowly but surely) began to accept openly gay members. Most importantly, a recent amendment to the Marriage Act of 1961 now defines marriage as a union of two people; an amendment which removed the prohibition of same-sex marriages. These landmarks in the progression of social awareness surrounding sexual orientation are derivative of scientific findings disputing the "choice" theory. As outlined in Simon LeVay 's book, Gay, Straight, and the Reason Why, the result of someone 's sexual orientation "emerges from the prenatal sexual differentiation of the brain" (LeVay 2011: 271) What LeVay means in this context is, "whether a person ends up gay or straight depends in large part on how this process of biological differentiation goes forward, with the lead actors being genes, sex hormones, and the brain systems" (LeVay 2011: 271). Much research, proven and theoretical, has been done on the concept of what makes people gay. Many factors surrounding socialization in regards to sexual orientation have undergone extensive scientific scrutiny (LeVay 2011: 77). Although there is evidence that suggests social and environmental elements play a role in sexual orientation, it is

If sexual orientation is something that we can’t change or choose, then how are these specific preferences such as heterosexuality and homosexuality created? How does one person progress to either heterosexuality or homosexuality? Studies showed that there were genetic factors linked to influencing sexual orientation in males before they were born by increasing the female reproductive capacity in mothers during multiple births. (Iemmole, Ciani, 2008: 393) Though that doesn’t mean that there technically is a “gay gene” that has been discovered, just that several human genome studies has suggested promising areas of research that are pointing to that direction. (Iemmole, Ciani, 2008: 393) With more

In one article by Marcia Malory, “Homosexuality & Choice: Are Gay People ‘Born This Way’”, she goes into multiple studies on the genetics of a gay child's parents. A study conducted in 1993 the “gay gene” matter arose when it was looked into the homosexual children's parents having a different X chromosome marker. Nonetheless genes do not control our behavior completely as does environment. The brain may also play a role in sexual preference, like the study in 1991 showing the difference in neurons and pituitary glands. Later in the 2000s more studies showed that gay men have more symmetrical hemisphere and amygdala resembles that of women's. The brain develops in the womb and continues through late adulthood. When did a fetus choose its

There are multiple theories people hold on how they believe homosexuality started or is generally caused. However, after multiple studies and ongoing research the likelihood that it is nature, rather than nurture, based is going strong. Although, as of now, there has been no exact consensus among researchers, after examining possible genetic, hormonal, developmental, social, and/or cultural influences, to prove that homosexuality is completely one or the other, but it is usually found that people cannot choose their sexual orientation, but rather only

The world has come very far with all the dramatic changes we have faced over the years. Wouldn’t you agree? As much change as the world has been through there are still numerous social problems that still exist in society today. Amongst those numerous social problems, sexual orientation and inequality stand out to me. Research from biology, psychology, and sociology is where our understanding of sexual orientation comes from. There are two hypothetical theories researchers have discovered examining the biological basis toward sexual orientation. One concept is the neurohormonal theory, biologist contend that homosexuality is caused by abnormal sex hormone levels in utero. The alternative theory is based on behavioral genetics, determining the source and magnitude of genetic impact on sexual orientation. This theory suggested the concept that gay men were genetically female. Later this theory was proven to be false. Homosexuality was considered as a pathology or mental illness. Not every psychologists agreed with that perspective. A researcher by the name of Havelock Ellis stated that homosexuality was congenital and for that reason it could not be considered as a disease. Sigmund Freud another theorist had the concept that everyone is born bisexual and that either homosexuality or heterosexuality is developed through social and personal experience. Ellis and Freud both concurred that homosexuality was not a mental illness. Despite these researchers’ opinions in 1973,

Science is uncovered origins a lot of things over the centuries and the human created much great inventions and even explored the surface of the moon; however, one question still on everyone’s mind and science may have solved one of greatest mysteries yet which is: how did homosexuality and heterosexuality evolve? Many psychologist, biologist and scientist may agree with sexual orientation is output from a combination of biological, hormonal, environmental and emotional factors and those many factors that influence to a development of human sexual orientation. However, being homosexual or bisexual is not mentally ill or abnormal in certain ways, although sexual minority is part of social problems that makes output from misinformation or prejudicial attitude. Diversity in sexual orientation has been a subject that has been seen in different perspectives by the different people (LeVay, 2010). Today there are the homosexuals, heterosexuals and bisexuals orientated people are forming a part of our society. This paper conduct an overall study of important and strong factors and provides accurate information and explanation for those who want to better understand development of sexual orientation.

Even though there are many studies that are reliable, there are some studies aren't reliable. Researcher Dean Hamer of the National Cancer Institute did a behavioral trait study using a common linkage study where it looks for a link between a behavioral trait and a certain genetic structure. The results for his study concluded that there was a link on the "q28"region of the X chromosome in homosexual males. Then a while

It has long been debated where our sexual orientation comes from, particularly whether its biological or social forces driving these behaviors. In regards to homosexuality and bisexuals, some have argued that it may be a choice that these individuals are making.(Levay 2012: 41)Some have even said it is a mental disorder that one can recover from, but there is plenty of data that says otherwise.(Levay 2012: 41)(Levay 2012: 65) I believe diverse sexual orientations develop in humans due to sex hormones during fetal life, gene influences, and other effects such as birth order influences. I’ve come to this conclusion based on the narrative provided via Dr. Simon LeVay’s book Gay Straight, and the Reason Why, and the research that has been compiled showing strong influences from a multitude or reasons. I will also be looking at a research paper by Francesca Iemmola and Andrea Camperio Ciani, who looked into genetic factors influencing sexual orientation in men. It is clear there are gender differences between men and women, and this is probably one of the strongest indicators that hormones can affect the outcome of variations in gender traits.

If the argument of homosexual animals is not convincing enough, one must also consider the possibility of genetics. There is research suggesting that certain genetic markers on the x-chromosome are associated with homosexuality: “Using genetic mapping, the team found that a set of five genetic markers at the tip of the long arm of the X chromosome were identical in 33 of 40 pairs of homosexual brothers” (Journal Watch). This does not positively conclude that a person will be gay if he or she has these markers, but it does suggest that there are genetic factors at play rather than sexuality being merely a choice. Much of this research was done in 1993, and: “The same year, a study of twins found a significantly higher correlation of sexual orientation between identical as opposed to fraternal twins” (Bernstein 34). Two people with the same genetic makeup are more likely to both be gay or both be straight than two people with similar but not quite identical genetics.

Most researchers agree that homosexuality is multi-causal and complex; many factors contribute to the development of same-sex attraction. They also believe that the homosexuality has nothing to do with the biological or genetic. If homosexual impulses are not inherited, what kinds of influences do cause strong homosexual desires? Some researchers believe that causes of homosexuality include the individual, family, society and media.
