Sterility caused by functional absence of ejaculatory ducts.

Abstract

Five patients with functional absence of genital excretory ducts are presented, with emphasis on the scarcity of physical and complementary data obtained. The low impairment of spermatogenesis is pointed out. Seminal characteristics are analysed and the diagnostic importance of spermogram data stressed. The importance of the qualitative determination of fructose for the diagnosis of this syndrome is noted, as well as the incidence of this syndrome as the cause of azoospermia and sterility. The existence of a unilateral congenital absence of ejaculatory ducts is demonstrated. Cases of this sort cannot be detected unless a contralateral acquired lesion occurs.
