[Varicocele and male hypofertility. Report of 100 cases].

100 cases of man-hypofertility associated with a varicocele have been submitted to a varicocelectomy using Ivanissevitch's procedure. Pre-operative spermogram and spermocytogram as well as testicular biopsy proved to be of no prognostic value. The only difference between pre-operative and post-operative spermocytograms concerns sperm motility. The main prognostic factor seems to be normal findings in the gynecologic examination of the female partner. Ligation of spermatic artery appears to be associated with a higher rate of failure.
