A condition in which components of both testes and ovaries are present in the same individual. Although true hermaphroditism is common among lower forms of animals such as annelids and mollusks, it is rare in humans. A more common condition in humans is pseudohermaphroditism, which simulates hermaphroditism. In female pseudohermaphroditism, or gynandry, the external sexual characteristics are in part or wholly of the male aspect, but internal female genitalia are present. In male pseudohermaphroditism, or androgyny, the individual has external sexual characteristics of female aspect, but has testes (usually undescended).
