精管欠如症について

Abstract

Congenital absence of the vas deferens has been rare l y reported and a literature review also shows that this condition is rather uncommon. Here we reported five cases of this anomaly, three occured bilaterally and two unilaterally. All cases ever reported in Japan was tabulated. B ilateral absence of the vas is obviously a cause of sterility in the male and should be kept in our mind when we examine a childless couple.
