The World Health Organization refers to sex as “the biological and physiological characteristics that define and differentiate men and women.” Although gender is now widely referred to as the more social and cultural aspect of this "[differentiation]", accepted cultural perspectives on gender are often conflated with sex, dictating that women and men are categories of be naturally and unequivocally defined, with distinct psychological and behavioral characteristics. propensities that can be predicted based on their reproductive functions and/or anatomical makeup. In this sense, the practice of gender could be considered a sexual practice in which the performance of gender is only an extension or prescription within the plasma framework of the individual. This is the fundamental principle of the idea defended by those who attempt to present scientific arguments concerning the “feminine”. and “masculine” behaviors. This is illustrated in the study “The Moral Molecule” by renowned neurobiologist and economist Paul J. Zak (2012), in which he argues that because there are higher levels of oxytocin production ( a hormone that facilitates intimacy), women tend to be more nurturing, more nurturing, more trustworthy, and more empathetic. Men have a higher concentration of testosterone, a “scientific fact” long established by early gender experiments (Vermeulen, Goemaere, & Kaufman, 1998; Seeman, 1998; Gupta, Lindemulder, & Sathyan, 2000; Stanton, Wirth, Waugh and Schultheiss, 2009). ). Testosterones, as Zak claims, are a very potent inhibitor of oxytocin, which "explains" the tendency for men to be stoic or more detached during social interactions and relationships. Coupled with the fact that the amygdala (often associated with aggression) is an area of ​​the brain in men that grows faster than the rest of the...... middle of paper ...... social truths can be explained through classic sociological conceptualizations of identity. Herbert Blumer (1969) popularized the term "symbolic interactionism", a continuation of GH Mead's (1913) theory of the self and CH Cooley's (1902) mirror self, arguing that human behavior is unique in that we react to symbols. This identity is formed through a process of reflection, making meaning of the world around us and the way we act corresponds to our understanding of these meanings. This notion of "meanings" is explored in the "linguistic turn", a postmodern development in Western philosophy and sociology rooted in the impression that all of society is made up of "signs and symbols" and that they do not mean than what we assume they represent. (Wittgenstein, 1953). These hypotheses, however, are not formulated objectively..
