There is much to learn about the biology underlying sex and gender development, and how sex differences result in higher or lower incidences of disease and responses to treatments. Check these links to learn about WashU investigators who study sex differences, published findings, and additional resources related to sex and gender.

Glossary

  • Assigned sex: determination made at a person’s birth based on an infant’s anatomy and/or sex chromosomes.
  • Cisgender: when one’s gender identity and assigned sex coincide with societal norms (e.g., man and male).
  • Gender identity: a label used to describe one’s identity within a given society’s understanding of gender.
  • Nonbinary: a person who does not subscribe to conventional gender categories but identifies with neither, both, or a combination of genders. Related terms include genderqueer, gender fluid, and more.
  • Transgender: when gender identity and sex do not coincide with societal norms.
