Varicocelectomy with primary gubernaculum veins closure: A randomised clinical trial

Abstract

To evaluate the effect of microsurgical inguinal varicocelectomy with testicular delivery on semen parameters. A total of 416 patients, diagnosed with grade III varicocele, were randomised into two groups. One group underwent microsurgical inguinal varicocelectomy without testicular delivery. For the other group, testicular delivery and ligation of gubernacular and all collateral veins were performed. A semen analysis was performed before and 6 months after the procedure. Mean age of the patients in the case and control groups was 27.3 ± 6.1 years and 25.9 ± 4.6 years respectively (p = .1). The total number of recurrence after 6 months in the conventional and testicular delivery groups was 13 (6.5%) and 3 (1.5%) (p < .05). No case of hydrocele formation was observed in any of the groups. All sperm parameters were improved 6 months after the surgery in both groups. But comparing the mean improved difference between the two groups revealed a significant difference in improvement in sperm motility for patients who had undergone varicocelectomy with testicular delivery (p = .05). Microsurgical inguinal varicocelectomy is a safe and efficient technique with a minimum chance of post-operative complications and recurrence and also may have role in improvement of sperm motility compared with conventional techniques.
