We report on 2 brothers with congenital absence of the vas deferens discovered in childhood during inguinal hernia repairs. The vas is absent unilaterally in one sib and bilaterally in the other. The unusual presentation of inguinal hernias in these children is discussed as well as mechanisms of inheritance and associated risk of renal anomalies.
