Biological Sex: A scientifically established categorization of male, female, and intersex based on the anatomical structures (genitalia, secondary sex traits), hormone levels (androgen and estrogen), and genetic composition (XX, XY, or other chromosome combinations). It is more complex than the sex assigned at birth, which is only determined by the appearance of genitalia.

Sex Assigned at Birth: Refers to the biological anatomy that is assigned at birth and categorizes individuals into male (has male anatomy), female (has female anatomy), or intersex.3 Sex assigned at birth is determined by doctors based on the appearance of genitalia in ultrasound or at birth. One’s sex assigned at birth and gender identity may differ, see Gender Dysphoria and Transgender

Cisgender: An individual whose gender identity matches their sex assigned at birth.Cisgender men are assigned male at birth, and cisgender women are assigned female at birth.1

Sex: Used in a variety of ways. A person’s identity as being male, female, or intersex. This term may refer to one’s biological sex or sex assigned at birth, often the latter. This term is also used to refer to sexual behavior.1

Gender Expression: The many ways in which an individual displays femininity, masculinity, neither, or both. Gender can be expressed through behavior, speech, pronouns, clothing, etc.3

Gender Fluid: A person who is able to display and adapt to various genders.This is another way of saying genderqueer or non-binary. 

Gender Binary: The classification of only two genders: either male or female.Often the view of many people that there are only two genders that can lead to strict representations and expectations of masculinity and femininity in culture. This classification excludes transgender or genderqueer individuals.

Gender Roles: Expectations, rules, behaviors, and roles given to males and females by society, such as masculine traits for males and feminine traits for females.4 Gender roles are socially constructed, and the expectations and pressures of a certain gender’s roles can be toxic in certain situations and for certain people.

Non-binary: An umbrella term for all gender identities that do not fall into the gender binary. Also used as a gender identity on its own.

Concluding Remarks

It is extremely important to respect an individual’s self-identification. A person should never assume another person’s identity based on behavior and appearances. If you are ever unsure about a person’s identity, we recommend asking the individual how they self-identify (in a respectful manner), as well as by which pronouns they prefer to be called. Always make sure to respect their choices.2 When introducing yourself to a new person or group of people, it may be helpful to express which pronouns you use.
