What is the distinction between sex and gender? Is there even a distinction between the two? How are these concepts shaped? Are these two concepts constructed by the same source? The distinction between sex and gender was not popularized until the 1970s, when it became the foundation of Western feminist thought. A traditional feminist definition of sex and gender is included in Ann Oakley's book, Sex, Gender, and Society, where sex is defined as a biological characteristic and gender as a "matter of culture: it refers to the social classification into masculine and feminine. (16). Using Oakley's definition of “gender,” we begin to view the difference between male and female attitudes and behaviors as distinct features of the social order. The definition is, however, very limited in understanding the whole concept of gender. Does gender derive from sex? Does sex necessarily determine gender? Harold Garfinkel, a sociologist, conducted a study on Agnes, who was born a man and underwent sex reassignment surgery to become a woman. In her article “Passing and the Managed Achievements of Sex Status in an Intersexed Person,” Agnès states that she always felt and was like a girl (65 years old). That said, we cannot assume that sex (genitals) is the only source that determines gender, because in Agnes we see a knowledge that seems to have contributed to the construction of her gender identity even before she was physically transformed into a woman. This awareness is also observed in Agnes when she mentions that before her operation, she was also trying to go out in society, find a job, go to clubs and interact with others, displaying a feminine appearance, like wearing dresses, heels, fixing clothes. her hair and putting on makeup (61). In the middle of the article, they continue to focus on gender after leaving their main discourse [family life], and how they "establish themselves as part of socially structured communities that connect individuals to social institutions and cultural ideologies” (8). Gender evolution is a continuous journey due to certain manifestations that evolve certain aspects of society. As we move through different stages of life, or as we move from our Primary Discourse to secondary Discourses [public institutions other than the family or a passionate group], we begin to understand "new" ways of becoming a girl. or a boy. By constantly analyzing the "doing of gender" between women and men, we begin to see a social reproduction, or in this case, a reproduction of gender norms, not only in how these gendered practices construct identity, but also on the way in which identity constructs and maintains the ideological conception. gender and gendered acts.
