RÉSUMÉ

OBJECTIVES: The most common indication for treatment of varicocele is still male subfertility. The aim of this study was to explore the effect of infertility duration on semen parameters and spontaneous pregnancy rate after varicocelectomy. MATERIALS AND METHODS: The medical records of 183 infertile patients with clinical varicocele were retrospectively reviewed. The patients were divided into three groups according to the duration of infertility (group I, 1-3 years, group II, 3-6 years and group III, > 6 years). Total sperm motility counts (TMCs) before and after varicocelectomy and spontaneous pregnancy rate among these groups were statistically compared. RESULTS: The greatest changes, regarding preoperative and postoperative TMCs and spontaneous pregnancy rate were noticed between group I and III. Preoperative TMCs in group I and III was 15.2 ± 1.2, 7.8 ± 1.4, respectively (p < 0.05). Postoperative TMCs in group I and III was 33.7 ± 2.5, 25.2 ± 1.9, respectively (p < 0.05). An overall spontaneous pregnancy rate of 34.4 percent was achieved after inguinal varicocelectomy. The greatest spontaneous pregnancy rate was achieved in Group I (37.3 percent), and the lowest pregnancy rate in Group III (26.3 percent) (P < 0.05). CONCLUSIONS: Surgical varicocelectomy improves the total sperm motility counts especially in patients who have a TMCS more than 5 million and improves the spontaneous pregnancy rates. The improvement in the spontaneous pregnancy rates after varicocelectomy correlates negatively with the duration of infertility. Therefore, duration of infertility should be considered in treating a patient with a varicocele as a cause of infertility.
