Objective: To evaluate the effect of varicocelectomy on sperm retrieval at testicular sperm extraction (TESE) and at spermiograms in patients with nonobstructive azoospermia. Materials and Methods: An observational study was conducted from April 2008 to December 2011. The study included men with a clinical diagnosis of nonobstructive azoospermia with a history of clinical unilateral varicocele (only grade III). After providing consent, the patients were treated with 2 different strategies according to the timing of varicocelectomy: group 1, varicocelectomy before microsurgical TESE (3 months); and group 2, varicocelectomy during microsurgical TESE. At 6 months after varicocelectomy, we evaluated the semen analysis findings for all patients. All patients underwent subinguinal microsurgical varicocelectomy. We also evaluated the percentage of sperm retrieval during TESE. Results: During the study period, 35 patients were enrolled. Group 1 included 19 patients and group 2, 16 patients. The sperm retrieval rate during the spermiograms was significantly greater in group 1 (57.8%) than in group 2 (37.5%). The percentage of sperm retrieval during TESE between the 2 groups was significantly greater in group 1 (57.8%) than in group 2 (27%; P <.05). conclusion: our results have suggested that varicocele repair significantly increases the sperm retrieval rate in patients with clinical varicocele and nonobstructive azoospermia at both tese and spermiogram.>
