Intersex

Describes a range of variations in primary and secondary sex characteristics that do not fit into binary notions of female or male bodies. Variations may involve sex chromosomes, external genitalia, gonads, hormone production, hormone responsiveness, and/or internal reproductive organs, and may be identified prenatally, at birth, during puberty, or later in life. Some people with an intersex variation choose to label their gender identity as intersex. People with intersex variations are typically assigned a female or male sex at birth; in a few jurisdictions, an infant may be assigned intersex at birth. Another medical term for intersex is differences of sex development.
