Assigned sex is the label given at birth by medical professionals based on an individual's chromosomes, hormone levels, sex organs, and secondary sex characteristics. As a note, the term "biologic sex" is understood by many to be an outdated term, due to its longstanding history of being used to invalidate the authenticity of trans identities. Although sex is typically misconceptualized as a binary of male (XY) or female (XX), many other chromosomal arrangements, inherent variations in gene expression patterns, and hormone levels exist. Intersex categorizations include variations in chromosomes present, external genitalia, gonads (testes or ovaries), hormone production, hormone responsiveness, and internal reproductive organs. Medical classification of intersex individuals is not always done at birth, as many intersex traits do not become apparent until puberty or later in life. Currently, there are at least 40 known variations that fall into intersex classifications (Carpenter, 2018). Notably, complex biologic variations can occur in everyone, and sex may best be viewed as a spectrum comprised of many traits. Gender is widely understood to be distinguished from sex and is an experienced aspect of self and a social construct of norms, behaviors, and roles that varies between societies and over time.
