OBJECTIVE: To investigate the intra-vaginal ejaculation latency time (IELT) of varicocele patients, the influence of spermatic vein ligation on IELT, and the relationship of Visual Analogue Score (VAS) with IELT.
METHODS: We selected 112 males who had regular sexual life after spermatic vein ligation and conducted follow-up visits for 6 months. According to preoperative IELT, we divided the patients into an IELT < or = 2 min group and an IELT > 2 min group, and compared their IELT, VAS and Chinese Index of Sexual Function for Premature Ejaculation-5 (CIPE-5) scores before and 6 months after operation.
RESULTS: Follow-up was accomplished in 81 of the patients, 18 in the IELT < or = 2 min group and 63 in the IELT >2 min group. Compared with the baseline, IELT was significantly prolonged postoperatively in both the IELT < or = 2 min group ([1.26 +/- 0.37] vs [4.53 +/- 1.69] min, P < 0.01) and the IELT >2 min group ([5.14 +/- 2.03] vs [7.69 +/- 4.51] min, P < 0.05); the postoperative CIPE-5 scores were remarkably improved in the former (11.27 +/- 3.52 vs 15.64 +/- 2.37, P < 0.05) but insignificantly in the latter group (20.42 +/- 4.65 vs 21.83 +/- 5.49, P > 0.05); the postoperative grades of the CIPE-5 scores showed significant differences in both groups (chi2 = 6.353, P = 0.042 and chi2 = 3.910, P = 0.048); the postoperative VAS was markedly increased (3.18 +/- 0.92 vs 1.56 +/- 0.83 and 3.24 +/- 0.95 vs 1.74 +/- 0.79, P < 0.05), with significant differences in the grades of VAS in both groups (chi2 = 4.433, P = 0.035 and chi2 = 10.088, P = 0.001). The variation of VAS was negatively correlated with that of IELT in both groups (r = -0.572, P < 0.01 and r = -0.465, P < 0.05).
CONCLUSION: Varicocele may be one of the causes of premature ejaculation, and some of the varicocele patients with IELT < or = 2 min may benefit from spermatic vein ligation. Improved VAS is negatively correlated with prolonged IELT. The relationship between varicocele and premature ejaculation deserves further studies.
