Congenital anomalies of the seminal ducts.

The frequency of individual congenital anomalies of the deferens, the seminal vesicles, the ejaculatory ducts and the utricle in 158 patients treated for sterility was determined by the method of deferentovesiculography by punction. Congenital anomalies were found in 14 patients (8.8%). Anomalies of rare occurrence are demonstrated in detail. The relation of such anomalies to sterility of patients is described.
