Refers to anatomical, physiological, genetic, or physical attributes that determine if a person is male, female, or intersex. These include both primary and secondary sex characteristics, including genitalia, gonads, hormone levels, hormone receptors, chromosomes, and genes. Often also referred to as “sex,” “physical sex,” “anatomical sex,” or specifically as “sex assigned at birth.” Biological sex is often conflated or interchanged with gender, which is more societal than biological and involves personal
identity factors.[2]
