title: [Spermatic vein ligation and intra-vaginal ejaculation latency].
abstract: 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).
  
  
  CONCLUSIONS
  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.
