The determination of gender identity is much deeper than whether a person is born a male or a female. The exact identifier that separates gender identity is currently unknown but researchers believe that genetics, hormones, reproductive organs, biological, and environmental factors all play a role in distinguishing a person’s gender identity. A person’s physical gender and their sense of gender are formed at two different times in two different parts of the body. A person’s gender is whether they are born male or female, but the way they identify themselves may be the opposite, which is not uncommon and has occurred since the beginning of time. In culture males are known to be the stronger, more aggressive sex, while females are the fairer, more nurturing sex. Usually, by the age of four, individuals have identified their gender identities aside from what gender they were born as physically. Throughout this paper, I will discuss the biological factors of gender identity (nature), environmental factors (nurture), and the role between hormones and behavior, and how these interactions all affect the determination of one’s gender identity.
Gender identification begins to develop while the fetus is in the beginning stages of development. Between weeks six and twelve of gestation is when the fetus begins developing reproductive organs and that is when the fetus takes on the role of male or female. Hormones are produced in both the nervous system and the endocrine system and are transported through the blood stream. Specifically, hormones are chemicals that combine and respond to certain cell receptors. Hormones like testosterone and androgen are mainly found in the male gender while estrogen is mainly found in the female gender. Testosterone is a contributing factor to behaviors like aggression. “Gender identity, an individual’s self-awareness of maleness or femaleness, and gender role, are programmed for the child within his mother’s womb,” (Institute of...
