[Varicocele as a cause of disorder in fertility (author's transl)].

In this study the pathophysiological connections in varicocele genesis are discussed, as well as its effect upon spermiogenesis and the causal factors. In 73 patients the high retroperitoneal ligature of the testicular vein was performed. Indication was given either on the basis of subjective complaints or on the proof of subfertility. In 79% of the cases a good anatomic result was obtained after operation. Of the spermiograms established prior to operation 56% showed postoperatively a distinct improvement in quality. In 52% of the sterile marriages conception occurred following operative intervention. In our clinic the operative method according to Bernardi is preferred, since it meets best the criteria of an ideal varicocelectomy. Operative intervention should take place early for possible preventing of spermiogenetic lesion.
