Intersex

• Developmental abnormalities resulting in discordance between genetic, gonadal or phenotypic sex.
• Includes true hermaphrodites, pseudohermaphrodites and other forms of sex reversal.

Hermaphroditism

• Individual possessing gonads of both sexes.
• Rare

Aetiology

• Failure of embryological differentiation of gonads during foetal life leads to the presence of both ovarian and testicular tissue (ovotestis or one of each type).

Consequence

• The tract is predominantly female, although there is often an enlarged clitoris and reduced vulval lips.
• Usually XX with H-Y antigen (protein normally coded for by Y chromosome).
