Definition of Intersex
Intersex: A group of conditions sometimes referred to as disorders of sexual development (DSDs) in which there is a discrepancy between the appearance of the external genitalia and the type of internal (testes and ovaries) genitalia. The condition was formerly termed hermaphroditism or pseudohermaphroditism. One example of intersex is androgen insensitivity syndrome, in which the body's receptors to male hormones do not function properly. In this case, individuals have a male genetic makeup (XY) and testicular tissue but have incompletely formed or female external genitalia. In some cases, known as true gonadal intersex, a person has both ovarian and testicular tissue.
