Biological Factors In The Development Of Homosexuality

Is Sexual Orientation Biologically Based or Choice? Over the years there has been many debates and experiments to try to come to the conclusion of whether sexual orientaion is biologically based or choice. Sexual orientation is a pattern of emotional, romantic, or sexual attractions to men, women or both sexes. Sexual orientation is defined in terms of relationships with others since their identity is based off of their attractions. Sexual orientation can be noted through behaviors such as holding hands or kissing, sharing goals and values, mutual support, and ongoing commitments. Sexual orientation can be broken down into three categories heterosexual, homosexual, and bisexual. While this break down may seem very black and white, there are

Biology Genes tend to play in important part in the sexual orientation. Prenatal hormones also play a major role in sexual orientation. According to Broderick and Blewitt, (2015) “Girls who are exposed to high levels of prenatal androgens are often found to have a greater frequency of homosexual experiences and fantasies than their non-cognitive adrenal hyperplasia female relatives”

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

3. Based on the nature theory homosexual behavior in men and women can be related to hormonal imbalance. Sexual orientation is determined by the early levels (probably prenatal) of

What Causes Homosexuality? 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

Causes & Explanations As it stands, there is no concrete evidence explaining why some individuals are homosexuals. There are however, two contradictory causes to homosexuality: (1) homosexuality is innate and (2) homosexuality is a choice.

Is Homosexuality Biologically Based The scientists’ opinions about the origin of homosexuality differ and neither of them have been proved enough yet. The aim of the present essay is to find out pros and contras for both theories: whether homosexuality is a moral or biological aspect. One of the strongest arguments in

Another research suggests that sexual orientation is impacted by a gene or genes found on the X chromosome. Though genetic tendencies for homosexuality may be passed from mothers to their children (Rahman & Wilson, 2003). During human evolution, homosexuality was developed to minimize competition between males for a limited number of potential female mates (Schulling, 2004).

One theory that many psychologist and scientist are trying to prove is that homosexuality has a fundamental biological basis. Similar to most mammalian species, humans at conception are females (McKnight 22). Toward the end of the first trimester is when the babies with a “male genetic message” begin to have small doses of two hormones, chorionic gonadotropin and luteinizing hormone, which start the altering process of the gonads into testes (McKnight 22). The hormones two jobs are to control the sexual development and control their function (McKnight 22). When the brain starts to develop masculine characteristics and lose the feminine characteristics, the processes are separate and occur at different

The predictor for sexual orientation has been debated and analyzed for a long time. Two explanations that have established possible predictors are biological factors and envionrmental factors, more commonly known as the "nature vs. nurture" debate. According to various studies, these factors play a unique role in determining ones sexual orientation. For clarification, sexual orientation as illustrated here is defined as "distinct preferences consistently made after adolescence in the presence of clear alternatives" (King, 226).

The research article suggests a structure within the human brain and a genetic link indicate the biological factor for male homosexuality. The journal investigates an experiment about the role of male genetics in sexual orientation by analysing the hypothalamus in autopsy specimens from homosexual and heterosexual men. Increased possibilities of same-sex orientation were discovered in the maternal male cousins and uncles of the participants, instead of their father or parental relatives. Also, the researchers discovered a brain cell group ‘INAH’ had a potentiality of being the sex-orientated DNA, indicating that the reason of homosexuality may be related to genetics.

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)

Homosexuality: Biological or Learned Behavior Axia College of University of Phoenix Homosexuality is at the front lines of the nature versus nurture debate. Many studies have been conducted, but a clear cause has yet to be found. Anti-homosexuals, consisting mainly of religious groups, believe that homosexuality is abnormal, unnatural, and can be changed. Because of their beliefs, homosexuality must be a learned behavior. Whether homosexuality is biological or learned behavior is still a mystery, but scientists are finding more evidence to suggest the former.

I believe that there is no way to definitively explain how people become interested in certain sexual desires, although an argument can be made for those who were sexually exploited as a child, which I will also discuss. I think that people are constantly evolving, and as we change through
