Hi! I’m here to help you explore the subject of body parts. This is all about biological sex, which, for a long time, was thought to be pretty simple. If you’re born with a penis, you’re a boy, right? It turns out, we are as different on the inside as we are on the outside. In this section, we dig into the science behind biological sex and what it means to more than just male or female. Let’s get started…
Explore the many ways in which our bodies can differ.

(Noun) A social construct used to classify a person as a man, woman, or some other identity and ascribe qualities of masculinity and femininity to people. Gender characteristics can change over time and vary between cultures.
(Noun) Clinically significant distress caused when a person does not identify with the sex they were believed to be at birth. Can also describe a desire to change the characteristics that are the source of the distress, such as physical anatomy.
(Adj.) Describes a person who identifies their gender as shifting within a spectrum of gender identities and expressions. A person who is gender fluid may always feel like a mix of two (or more) genders, but may feel more one gender some days, and another gender other days. Gender-fluid people may or may not also identify as transgender.
(Noun) An umbrella term for more than twenty distinct medical conditions in which a person is born with physical sex markers (genitals, hormones, gonads, chromosomes, or secondary sex characteristics like breasts or body hair) that are neither clearly male nor clearly female. Also referred to as disorders of sexual development (DSD).
Sex / Sex assigned at birth / Biological sex
(Noun) A person's sex (male, female, or intersex) is often determined based on the appearance of the genitalia, either in ultrasound or at birth. In reality, biological sex is more complicated, referring to a combination of anatomical, physiological, genetic, and physical attributes. These include genitalia, gonads, hormone levels, hormone receptors, chromosomes, genes, and secondary sex characteristics. The phrase "sex assigned at birth" is used by some to emphasize that genitalia alone are not always a sufficient indication of a person's sex, as well as the fact that a person's gender identity is not always aligned with the sex characteristics observed at birth.
