Inguinal hernia containing a paramesonephric (Müllerian) duct in an adult male. A case report.

This article describes the extremely rare contents of a right indirect inguinal hernial sac in an adult male, namely a paramesonephric duct. Radiological investigation at operation by means of 'salpingography' demonstrated the connection of this 'uterus' with the prostatic utricle. 'Salpingohysterectomy' was performed. Sex typing of the patient determined him to be a male. His family history revealed siblings with intersex features; the prenatal determination of sexual identity is discussed and reference made to the fate of the mesonephric (Wolffian) and paramesonephric (Müllerian) remnant.
