Birth assignment

Birth assignment, also called gender assignment or assigned gender at birth (abbreviated AGAB), refers to the gender or sex that was assigned to an infant upon their birth, usually based only on the appearance of their external genitalia. This is done with the assumption that an individual's eventual gender identity will match their birth assignment&mdash;assigned male at birth (AMAB) or assigned female at birth (AFAB). This is not the case for transgender people. Birth assignments are recorded as "sex" on birth certificates.
