Impact of varicocelectomy on premature ejaculation in varicocele patients

摘要

In a prospective manner, we studied the effect of varicocelectomy on premature ejaculation and testicular hormonal function in patients with varicocele. Microsurgical subinguinal varicocelectomy was carried out in 73 patients with clinical varicocele associated with premature ejaculation (group 1) and compared with 56 patients without operative intervention (group 2; control). The primary efficacy variable was the mean change in the Premature Ejaculation Diagnostic Tool. The changes in International Index of Erectile Function questionnaire, total serum testosterone and testicular size were also assessed. In group 1, the Premature Ejaculation Diagnostic Tool decreased significantly after varicocelectomy, from 15.56 to 11.37 (P<0.001), indicating improvement of premature ejaculation. Thirty patients (41.1%) showed improvement of premature ejaculation compared to 5.3% in the control group (P<0.001). In group I, but not in group II, testosterone levels and International Index of Erectile Function values increased significantly when compared with pre-operative values (P<0.001 and 0.040 respectively). Testicular size increased after varicocelectomy, but this increase was nonsignificant till the end of study (P=0.054). We concluded that varicocelectomy is clearly related to improvement of premature ejaculation and testicular hormonal function in varicocele patients.
