Sex Unknown

Gender is actually a set of rules, customs and traditions assigned to people of a particular sex. Gender is not biological but sex is. Rather, according to Lorber, it is influenced by our society and our culture. By proving this claim, Judith Lorber has put forth the example of the man and this example is efficient in distinguishing “gender” as a practice than as an innate attribute.

| Researchers have found that the female hippocampus tends to be larger than the male hippocampus. Based on evidence presented in the Critical Thinking box in the text, “ 'His ' and 'Her ' Brains?” you would be justified in asserting which of the following?1. Because of the differences in the size of the hippocampus, females will be

Assumptions about gender are embedded in scientific bias. In Cordelia Fine’s From Scanner to Sound Bite: Issues in Interpreting and Reporting Sex Differences in the Brain, the author examines four scientific issues that are overlooked about sex differences in the brain. She concludes that there are numerous misinterpretations of neuroimaging research that ultimately influence gender biases, and society should be cautious when reading these articles about sex differences.

In 1997, Rolling Stone Magazine published The True Story of John/Joan. This true story, about the real life Bruce Reimer, chronicled the diagnosis and lifetime of a man who was given gender reassignment surgery as a small child due to an accident during the circumcision process. Every attempt was made by both parents and doctors to raise him as a female and according to the female gender roles appropriate to the times. Nonetheless, Bruce remained adamant in his own gender identity as a male, rejecting feminine options from the very beginning (Colapinto, 1997). Despite clear evidence of the enormous social impact on the development of gender roles and suggestions that gender roles

Gender is one of the most prominent features of a human being and not enough people pay attention to the development of such delicate trait. Our gender contributes a lot to our daily lives. Whether we are shopping or talking to somebody, people act differently based on your gender. Penelope Eckert and Sally McConnell-Ginet wrote just about this peculiarity in their article “Learning to be Gendered”. Penelope Eckert’s and Sally McConnell-Ginet’s article exposes some things that define a boy as a boy and a girl as a girl.

Kimura’s scientific article Sex Differences in the Brain provides an excellent scientific basis and intermingles social implications with scientific discoveries. It’s use of graphs and tables allow for readers to easily understand each point being driven and makes excellent use of past references to allow a full scope of comparisons. Borchers’ social science article Sociological differences between women and men: Implications for autoimmunity gives genuine insight into the differences of men and women’s abilities regarding everyday tasks and duties but falls short in it’s delivery and scope. I suffers from confusing in text statistics and poorly places graphs that make it difficult for a reader to understand. While of the same topic, the Kimura’s scientific article does a better job of not only presenting ideas but creating them as well. Bringing several different approaches to understanding how men and women function, the scientific article is the superior of the two for this

In a recent study done in August of 2013, scientists found that autism had a peculiar affect on the female brain. Researchers were looking to find differences between the two genders, something to support the already explored EMR theory, (also known as the “Extreme Male Brain Theory”), but they did not expect the possibility of the female autistic brain having a masculine resemblance. Scientists studied several men and women, with and without autism, which led to the discovery of the differences between the two genders.

Thus, concluding that the explanation of biological, psychodynamic and learning approaches does influence on gender development. Each of these approaches explains how gender is developed in their own way. From the biological approach, we found out that gender differences are seen as resulting from sex differences. In other words, women and men act, think and feel differently because of differences in how their brains work. These brain differences may result from chromosomal differences and may also be the result of hormonal differences.

William Reiner and John Gearhart conducted an experiment where sixteen males with an inadequate or no penis were reassigned to be female. The sex change took place within two weeks of age for thirteen of the subjects, and within twelve weeks for one subject. Although they were made into anatomical girls, and were raised as girls by their respective families, most of the children did not feel feminine. At the end of the experiment, five of the subjects claimed female identity, three were unclear of their gender identity, and eight of the subjects claimed male identity. The subjects who identified as female admit that they struggle to fit in with other girls, but all subjects agree that getting along well with males is easy. They also all displayed

In Stockholm, Sweden, an article stating researchers discover gay brain activity closely matches that of heterosexuals of the same sex was published in The National Geographic entitled, “Gay Men, Straight Women Have Similar Brains”. Figure one shows “Covariations with the respective amygdala seed region in hetero- and homosexual subjects. The Sokoloff scale indicates T values. Clusters detected at T = 3.0 are superimposed on the standard MR image of the brain” Which simply means that homosexual men and straight women showed more neural connections across the two brain hemispheres than heterosexual men did.

As the ethicist Dr. Alice Dreger points out, "one quickly runs into a problem. . .when trying to define 'key' or 'essential' feminine and masculine anatomy. In fact, any close study of sexual anatomy results in a loss of faith that there is a simple, 'natural' sex distinction that will not break down in the face of certain anatomical, behavioral, or philosophical challenges" (3).

There are many theories and approaches to gender in terms of biology and science in general, which aim to suggest or prove that gender is natural and inherent. The first of these is the effect of hormones, more specifically testosterone, which causes male behaviour patterns such as aggression, competitiveness and a higher sexual drive. Testosterone also helps in the development of the brain. The brain is divided into two hemispheres, a left and a right. The left side of the brain is specialised in language skills whereas the right hand side of the brain is used for more non-verbal such as spatial awareness skills. Shaywitz et al (1995) used MRI scans to examine the brain whilst males and females carried out language tasks of varying difficulties. It was found that females used both hemispheres of the brain to complete the task whereas males only used the

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.

Studies have also been carried out into whether or not there are differences between male and female brain size and whether this affects how we relate to each other in terms of gender. Simon Baron-Cohen believes that male brains are wired towards systematic understanding and females are wired towards empathy. In addition he says that this is not necessarily always the case but the majority are wired in this way: “Both sexes have their strengths and weaknesses. Neither sex is superior overall.” (Baron-Cohen, S. 2003).

As evident from the generalized patterns found in differences in behaviour and outlook observed between the sexes, it may be tempting, as has been done in the past, to conclude that gender is an unavoidable aspect of human existence as determined purely from one 's genes. Indeed, human physiology is subject to sexual dimorphism; statistically significant differences in brain size and rate of maturation of specific substructures in the brain exist between males and females (Giedd, Castellanos, Rajapakese, Vaituzis, & Rapoport, 1997), yet these physical differences fail to explain how individuals form their concept of their own gender, and why they tend to conform to their perceived gender roles as defined by the society in which they live, when these roles are ever-changing. Thus, it is important to differentiate between the physical and nonphysical traits, and how the labels of femininity and masculinity should not confuse the two aspects. As defined by Unger (1979), “sex” would be used to refer to the biological differences in males and females, while “gender” describes socioculturally determined, nonphysiological traits which are arbitrarily designated as being appropriate for either females or males. With more recent awareness and interest in matters of gender nonconformity and individual gender identity, new research now explains how these concepts of gender are shaped by social influences (Perry
