Assigned female at birth (AFAB) is a term used to describe someone classified as a female at birth. This typically occurs because the attending doctor feels that the baby's genitals appear more feminine than masculine.
The term encompasses people who are biologically female as well as intersex individuals who were female-assigned. It is most commonly used in trans, non-binary, and genderqueer communities.
Assigned female at birth may also be referred to as female assigned at birth (FAAB) or designated female at birth (DFAB).
