Popis: Summary Efficacy of surgical varicocelectomy versus embolization of the spermatic vein was studied in 137 men diagnosed as suffering from left varicocele. The men were divided randomly into three groups according to the methods of treatment: A -embolization of the internal spermatic vein (51 men); B - Ivanissevich technique of high ligation of the spermatic veins (43 men); and C - Bernardi technique of high ligation (43 men). The groups were similar in terms of age, duration of infertility and possessed semen characterized as oligoteratoasthenozoospermia. The fertility of the female partners was evaluated carefully and they were found to be potentially fertile. Varicocele was diagnosed by at least two of the following methods: physical palpation during valsalva manoeuvre, venography, or scrotal scanning using the technetium pertechnate radioactive method. Semen quality was assessed before treatment and at 3, 6 and 9 months post-treatment. Fecundity was followed-up for 18 months. The major results were: (i). Shrinkage of the varicocele was found in all three groups studied. The same rate of recurrence was recorded in the three groups (24%, 37% and 35% in groups A, B and C, respectively). (ii). Improvement of sperm quality was significant in groups A and B, with better results in group B. (iii). The pregnancy rate was significantly higher in group B, compared with A (38.2% vs. 20.6%; P
