[Hemodynamic changes in varicoceles and their relation to fertility].

Hemodynamic changes in the vascular bed of the affected testis were studied in 45 sterile and 6 fertile patients with varicocele. The examination method used was modified abdominal angiography. The most frequently recorded change in the arterial bed was persistence of the contrast medium in the left internal testicular artery (5 patients). All these patients were from the group of sterile subjects. The most frequent finding in the venous bed was venous reflux from the left renal vein into the left internal testicular vein (45 sterile and 2 fertile patients). In some sterile patients pathologic opening or origin of the vessels was observed. The substantially higher rate of hemodynamic changes in sterile patients suggests their direct relationship to spermiogenesis.

X-ray findings on the testicular artery in varicocele.

X-ray findings on the internal testicular artery following abdominal aortography are described. A group of 32 patients with left-sided varicocele were examined. The course of internal testicular artery was visualized in 27 patients. In 5 sterile patients prolonged filling of the left internal testicular artery up to the venous phase of the abdominal aortography has been observed. The non-physiological courses of the artery are described.

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.
