Persistent mullerian duct syndrome.

Persistent mullerian duct syndrome is a rare form of internal male pseudohermaphroditism in which mullerian duct derivatives are present in a genotypic (46XY) and phenotypic male. We report a rare case of persistent mullerian duct syndrome in an adult fertile male in whom mullerian duct derivatives (uterus and fallopian tubes) were found in the right hernia sac at herniotomy.
