In today’s day in age, different sexualities and gender identities are quickly becoming more accepted in mainstream society. Despite this change, there are many people who believe that having a different sexual orientation or gender identity is a choice that is frowned upon. In order to refute this belief, research and biology of the brain is necessary. Researching the brain on the basis of sexuality is a fairly new topic of discussion because it is somewhat difficult and confusing. This paper will explore the different identities of gender, sex and sexual orientation and the main biological reasons behind these. There is also some validity of different sexual orientations and identities through the evidence of sexual disorders like Klinefelter’s and Turner’s Syndrome and gender dysphoria.
In order to discuss the biology of gender identity and sexual orientation, it is necessary to first examine the differences between multiple definitions that are often mistakenly interchanged: sex, gender, sexual orientation, and gender identity. Sexual orientation is defined by LeVay (2011) as “the trait that predisposes us to experience sexual attraction to people of the same sex as ourselves, to persons of the other sex, or to both sexes” (p. 1). The typical categories of sexual orientation are homosexual, heterosexual and bisexual. Vrangalova and Savin-Williams (2012) found that most people identify as heterosexual, but there are also groups of people that identify as mostly heterosexual and mostly gay within the three traditional categories (p. 89). This is to say that there are not three concrete groups, but sexual orientation is a continuum and one can even fluctuate on it over time. LeVay (2011) also defines gender as “the ...

Homosexuality is a product of biology because according to research, the hormones of the females are stronger. Dr. Hamer states that sexual orientation, male homosexuality is genetically influenced. This is passed down through their mothers to the hormone of their offspring. Sexual identity is wired into the genes, which discounts the concept that homosexuality and transgender sexuality are a choice. Since sexual differentiation occurs within the womb, as a result of hormonal influences, it has been hypothesized that homosexuality may result from differential hormone balance in the wombs of those who eventually exhibit a homosexual orientation. According to a study, the question is whether homosexual practice changes the brain or whether the brain results in homosexual practice. According to Dr. Hamer, male homosexuality might be linked to a set of five DNA sequences located on the Xq28 region of the X chromosome. Therefore, if homosexual orientAtion were completely genetic, one would expect that it would not change over the course of one's life.
...ignificant evidence for my research argument indicates that the nature of gender/sex consists of a wide consensus. The latter is significant to original sex differences in brain structure and the organized role through sex differential prenatal hormone exposures through the term used in the article as (the ‘hardwiring’ paradigm). The article is limited to scientific shortcoming that presents neuroscientific research on sex and gender for it lacks an analysis that goes beyond the observed results. The article is based on neuroscience studies and how it approached gender, yet the article suggests that gender should be examined through social, culture studies, ethnicity and race. This article will not form the foundation of my research but will be used a secondary material. The neuroscience evidences will be used to support my argument and will be used as an example.
It is a common misconception that gender, sex, and sexuality are linked. In reality, sex refers to biology, whether a person was born with male or female chromosomes and genitalia,
Many people relate sex, gender, and your sexual orientation as the same thing grouped in two categories of male or female traits and preference, however as both authors argue it is imperative to view each as a separate and ever changing category in order to protect peoples beliefs who contradict the earlier statement. “Educating legislators and policymakers about the damage inflicted by sexism and gender stereotyping is a critical component of winning
Oestrogen receptors in the brain are believed to cause gender-appropriate behaviour. Oestrogen, a hormone found in the female genital tissue, acts as a ligand and, by activating the oestrogen receptors found on the surfaces of brain cells, causes notable changes in behaviour. Professors at Yale University have studied the effects of oestrogen and found the hormone increases neural connectivity in the brain resulting in a more accurate memory. Turnham et al (2002) supports this as upon investigation...

What controls a human's sexual orientation? The long-standing debate of nature versus nurture can be extended to explaining human sexual orientation. Is it biological or environmental? The biological explanation has been gaining popularity amongst the scientific community although it is only based on speculations. It is argued that sexual orientation is linked to factors that occur during sexual differentiation. The prenatal exposure to androgens and their affect on the development of the human brain play a pivotal role in sexual orientation (2). Heredity is also part of the debate. Does biology merely provide the slate of neural circuitry upon which sexual orientation is inscribed? Do biological factors directly wire the brain so that it will support a particular orientation? Or do biological factors influence sexual orientation only indirectly?
Despite the large collection of literature of sexuality that has been accumulating, human asexuality has been largely ignored. Asexuality is controversially considered to be a sexual orientation and people who identify as asexual are people who typically do not experience sexual attraction (Asexuality Visibility and Education Network, 2013). Though research on sex and sexual orientations has been done for centuries, the first real suggestion that there might be people who fall outside of the heterosexual – homosexual orientation spectrum came from Kinsey and colleagues in 1948. These individuals were put into a separate category and were identified as having no erotic response to hetero- or homosexual stimuli, but otherwise they were largely ignored by the researchers (Kinsey, 1953). Later, researchers linked asexuality with negative traits and pathologies, including depression and lower self-esteem (Masters, Johnson, & Kolodny, 1986; Nuius, 1983). An issue with these studies, however, is that the researchers defined asexuality in a way that most current asexuals do not agree with. For example, in a study done by Bell and Weinberg (1978), there were references made to asexual homosexuals who simply hid their homosexuality. Many asexuals, otherwise known as Aces, would struggle with this definition because homosexuality implies a type of sexual attraction: attraction to your same sex. Because Aces typically do not feel sexual attraction to anyone or anything, they should not be classified under the same label as a closeted homosexual. Another issue is that none of these studies actually focused on asexuality. Instead, they were added on the side and generally ignored.
Since the 1800's, psychiatrists and psychologists have concluded that homosexuality is a mental disorder. They have believed it is brought about by misguided upbringing and their social environments. For instance, it was believed that if the child was lacking a male - figure in the home, he would most likely be gay. Or that child abuse can lead to lesbianism when the special needs of a little girl are denied, ignored, or exploited and the future womanhood of the child is in risk. However, inconsistencies in the research subjects' abuse records ruled these theories out. And if this were the case, then why is homosexuality present in different cultures? Some believed homosexuality was caused by a difference in brain structure. In 1991, Simon LeVay published research stating that sexual orientation may be the result of differing brain structures. The hypothalamus, a region in the brain that governs sexual behavior, was the structure that LeVay was pointing as the structure at fault. In his studies of the hypothalamus, he found that in homosexual men, the hypothalamus was smaller than that of heterosexual men. Instead, it was the size of the female hypothalamus, consequently explaining their sexual tendencies.
Genetics, biology, and upbringing are all key aspects in determining one’s sexual orientation. Many of the factors are combined to make up how a person feels or who he or she is attracted to. There is no definite answer to why someone has a particular orientation, but there are studies that sugge...
Gender has been around throughout history; however, within recent years, gender has separated itself from the traditional view of sex, e.i., male or female, and has become centered on ones masculinity or femininity. Of course gender is more than just ones masculinity or femininity, gender has become a way for one to describe, he or she, in a way in which they are different from everyone else. Gender has turned into a sense of identity, a way for one to feel different and fulfilled among all of those around them. Of course gender’s sense of freedom would seem outside of structure and only affected by one’s own agency, however, structure is a key component in establishing gender. We can look into both ethnic Mexican’s culture practices regarding sexuality, children songs and games, and see that cultural traditions still heavily influence gender, creating what is masculine and what is feminine and what is the role of each gender, as well as challenging the notions that gender is solely based on agency.

Sexual orientation is a key aspect in any person’s life. The way of life for a gay, lesbian, and all sexual minorities are drastically different than those who are heterosexual. The critical time period for sexual development is in the early stages of childhood. Although childhood is a critical period, many studies have been conducted ranging from those in their twenties and thirties (Carver, Perry, & Egan, 2004). Storms (1981) believes that the content of one’s sexual fantasies that arouses the stimuli of their erotic orientation. Storms (1981) also stated that sexual orientation is a combination of social development and sexual development that takes place during an individual’...
The American Psychiatric Association does not define atypical sexual interests as a disorder unless it causes personal distress, causes another person psychological or physical injury, or involves a person unwilling or unable to give legal consent. These distinctions were made to show that individuals who engage in atypical sexual behavior must not be inappropriately labeled as having a mental disorder. When we think of sexual orientation, we usually think of the continuum of gay, straight, and bisexual, but sexual orientation is a deep-seated attraction toward a certain kind of person. Erotic desire includes attention, attraction, fantasy, thoughts, urges, genital arousal, and behavior. It is further complicated by variations of dominance or submission, sadism and masochism, fetishes, and consent or no consent. These interests may be single or multiple, exclusive or nonexclusive, idiosyncratic or opportunistic, stable or fluid. Possible legal consequences, lack of opportunity, and unwillingness or inability to act all work to constrain our behavior. The sooner we learn this concerning human sexual behavior, the sooner we shall reach a sound understanding of the realities of sex. The reasons for our sexual choices are analyzed obsessively, imposing an undue emphasis on categorization rather than accepting the great diversity of same-sex attractions. But the act of categorizing all of these atypical sexual attractions does not mean that acting on them is either legal or morally acceptable nor unacceptable. Explanations for all of the elements of our sexual attractions are complex and probably unknowable. All research runs the risk of reductionism, but when research on sexuality focuses exclusively on genital sexual activity --to the exclusion of considerations of attraction, affection and affiliation--it falls short in understanding our
Gender and sexuality can be comprehended through social science. Social science is “the study of human society and of individual relationships in and to society” (free dictionary, 2009). The study of social science deals with different aspects of society such as politics, economics, and the social aspects of society. Gender identity is closely interlinked with social science as it is based on an identity of an individual in the society. Sexuality is “the condition of being characterized and distinguished by sex” (free dictionary, 2009). There are different gender identities such as male, female, gay, lesbian, transgender, and bisexual that exists all around the world. There is inequality in gender identities and dominance of a male regardless of which sexuality they fall under. The males are superior over the females and gays superior over the lesbians, however it different depending on the place and circumstances. This paper will look at the gender roles and stereotypes, social policy, and homosexuality from a modern and a traditional society perspective. The three different areas will be compared by the two different societies to understand how much changes has occurred and whether or not anything has really changed. In general a traditional society is more conservative where as a modern society is fundamentally liberal. This is to say that a traditional society lists certain roles depending on the gender and there are stereotypes that are connected with the genders. One must obey the one that is dominant and make decisions. On the other hand, a modern society is lenient, It accepts the individual’s identity and sexuality. There is no inequality and everyone in the society is to be seen as individuals not a part of a family unit...
