Lower urinary tract symptoms (LUTSs) and ED are clearly correlated, but to date no correlation with ejaculatory dysfunction (EjD) has been identified. Therefore, this study evaluated the impact of erectile function in men with LUTS on EjD and premature ejaculation (PE). Erectile function, PE and EjD of 239 men (mean age, 53.0 ± 10.65 years), International Prostate Symptom Score (IPSS), International Index of Erection Function (IIEF), intravaginal ejaculatory latency time (IELT) and the seven-item Male Sexual Health questionnaire (MSHQ)-EjD were used to compare with the degree of LUTS. Ages were divided into five groups (<40, 40-49, 50-59, 60-69 and >70 years). The IPSS categorized patients into three symptom groups: mild, 1-7; moderate, 8-19; and severe, >19. ED was classified into five categories based on IIEF-EF scores: severe (0-6), moderate (7-12), mild-to-moderate (13-18), mild (19-24) and normal (25-30). The correlations among age, IIEF-EF, IELT and the MSHQ-EjD domain were studied through regression and cross-tabulation analyses. The results revealed that aging significantly affected each item of the MSHQ-EjD (P<0.05). The IIEF-EF domain was also correlated with each question on the MSHQ-EjD (P<0.05). PE (IELT <1 min) increased in incidence as patients got older but was not linked to IIEF-EF (P>0.05). These results indicate that EjD is closely related to age and erectile function, and that PE is closely related to age, although PE is not related to erectile function.
下尿路症状 (LUTS) 和 ED 显然相关，但迄今为止，尚未发现与射精功能障碍 (EjD) 相关。因此，本研究评估了患有 LUTS 的男性的勃起功能对 EjD 和早泄 (PE) 的影响。对 239 名男性（平均年龄 53.0±10.65 岁）的勃起功能、PE 和 EjD、国际前列腺症状评分 (IPSS)、国际勃起功能指数 (IIEF)、阴道内射精潜伏期时间 (IELT) 和七项男性性健康问卷 (MSHQ)-EjD 进行评估，并与 LUTS 程度进行比较。年龄分为五组（<40、40-49、50-59、60-69 和 >70 岁）。IPSS 将患者分为三组症状：轻度，1-7；中度，8-19；严重，>19。根据 IIEF-EF 评分将 ED 分为五类：严重（0-6）、中度（7-12）、轻度至中度（13-18）、轻度（19-24）和正常（25-30）。通过回归和交叉表分析研究了年龄、IIEF-EF、IELT 和 MSHQ-EjD 域之间的相关性。结果表明，衰老显著影响 MSHQ-EjD 的每个项目（P<0.05）。IIEF-EF 域也与 MSHQ-EjD 的每个问题相关（P<0.05）。PE（IELT<1 分钟）随着年龄的增长而增加，但与 IIEF-EF 无关（P>0.05）。这些结果表明，EjD 与年龄和勃起功能密切相关，而 PE 与年龄密切相关，尽管与勃起功能无关。
