Comparison of inguinal approach , scrotal sclerotherapy and subinguinal antegrade sclerotherapy in varicocele treatment : a randomized prospective study . We compared outcome and complications of three simple varicocelectomy techniques . Groups were divided according to whether they would receive the Ivanissevich technique ( n = 55 ) , Tauber 's technique ( n = 51 ) or subinguinal sclerotherapy ( n = 49 ) . Selection criteria were : infertility > 1 year , subnormal semen , sonographic diameter of veins > 3 mm and time of regurge > 2 s. Patients were randomly assigned to the groups of treatment , with follow-up every 3 months for 1 year . Improvement was only in sperm count and total motility for all groups . Pregnancy rates were 20 , 13.73 and 12.24 % , respectively , with no significant difference between groups . Hydrocele occurred only in the group which received the Ivanissevich technique ( 5.5 % ) . Tauber 's technique is simple ; however , it has the disadvantage of multiple branching of small veins .
