What does natal sex refer to?

Natal sex refers to the classification of an individual as male or female based on their physical characteristics, specifically the genital anatomy present at birth. This term emphasizes the biological aspects of sex, which are typically observed in newborns. It involves the assignment of sex based on observable anatomical features such as the presence of a penis or vagina.

In contrast, concepts related to gender identity, social roles, or medical conditions present at birth address different aspects of human identity and existence, which do not solely define an individual's natal sex. Thus, recognizing natal sex as tied to physical anatomy helps clarify the distinction between biological sex and other constructs related to gender and identity.
