Homosexuality Nature Or Nurture Analysis

Susan Ferguson stated that the basal ganglia system and the striatum are thought to create positive and negative

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.

Addictions are a diverse set of common and complex diseases that are to some extent tied together by shared genetic and environmental factors. Addiction includes alcohol use disorders, cannabis and cocaine use disorders, nicotine dependence, as well as non-substance–related behaviors. Both genetic and environmental variables contribute to the use and abuse of addictive substances, which may eventually lead to addiction.

Homosexuality is a choice; you are not born gay. People choose that life, it doesn’t choose you. It is impossible for you to be born gay because the gay trait would be recessive and would have died out a long time ago. Homosexuality is an ideal; those brought by experience and thoughts.

If sexuality is developed at an early stage in a person’s life, then how does homosexuality occur? Homosexuality in Darwin’s selection theory doesn’t even exist. (Roughgarden, 2009, 127) Some say that it’s based on the person’s surrounding environment and influences while others say that it’s purely genetic. There has been substantial evidence that points to both genetic and environmental factors in developing homosexuality, but no one factor that clearly pushes over the top to define the origins of homosexuality. Statistically if a male is straight then there is a 4% percent chance that his brother might be gay, but if the male himself is gay, then the percentage jumps to 22%. (Roughgarden 2009: 247) These statistics simply show that gay males tend to group in families, it doesn’t necessarily point out anything specific about the environment’s effects or the male’s genetic makeup. (Roughgarden, 2009, 247)

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

It seems that none of these options are conclusive, and it's reasonable to suppose that the cause, like human behaviour in general, is too complex to fit into a single simplistic model.

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 nature and nature of homosexuality is heavily debated. Some people believe that homosexuality is biologically determined and others believe it’s base on ones environment. This topic can be argue to be base on both nature and nurture. Studies conducted in the past decades support both the biological and environmental aspect of homosexuality.

The article concludes that homosexuality although still a mystery has a biological basis for why it occurs and the question is what and how does that biological mechanism play in the role of homosexuality. It seems there may be a difference between men and women as well in regards to the biological basis of homosexuality. I think that the human genome is immensely complicated not only do we have to deal with the sequencing data but we also have to take into account epigenetics factors which have been shown to change the actual sequencing data the genotype. Therefore, to me it is very complicated. The questions are what changes are happening in a person’s sexuality when genes are turned off, versus turned on? Understand how homosexuality occurs

Homosexuality has been a recent controversial topic, but many do not know that homosexuality has been around for thousands of years. Over the past years, there have been many speculations about causes homosexuality, such as it is a disease, or a choice, or just bad parenting. Slowly, homosexuality has been gained some support over the recent years, and there have been many types of research conducted to help explain how a person’s sexual orientation comes about. Over the years homosexuality has been heavily focused in psychology, but slowly has been merging into biology; mainly focusing on genetics. The purpose of this review is to summarize observations and results of previous research covering the connections between homosexuality and genetics.

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.

what ever decision has been made, it has been done so on the basis of

This paper is aimed to address the question of whether homosexuality is biologically based. This topic is quite relevant today because homosexuality is a huge civil rights issue which is also conflicting with the church 's moral standards. While many religious bodies claim that homosexuality is a choice and a "sin", many in the homosexual community have strongly refuted that claim, instead saying they were born this way and their sexual identity is not a choice for them. Currently one of the biggest debates regarding the rights of homosexuals is same sex marriage . If scientist are indeed able to show evidence that homosexuality is result of biologic or genetic

The study of its causation, however, has been greatly expanded only within past two centuries. Many theories have been formulated to attempt to explain what causes sexual variance, and in particular, homosexuality. These theories can be grouped into two main categories: nature and nurture. The theories which fall under the nature category maintain that homosexual behavior results from biological, innate differences between homosexuals and heterosexuals. The nurture theories, in contrast, state that homosexual tendencies form as a result of one’s sociological environment, and that homosexuality is an acquired trait.
