Our aim was to evaluate the relationship between lower urinary tract symptoms (LUTS), age, and sexual dysfunction in the Iranian men aged 50 to 80 years.
A total of 357 men aged 50 to 80 years presenting at the urological clinic were enrolled in this study. The International Prostatic Symptom Score (IPSS) and the International Index of Erectile Function (IIEF) questionnaires were used to assess the LUTS and sexual function, respectively. The questionnaires were completed by face-to-face interview. Logistic regression model was used for multivariate analysis of the risk factors of sexual dysfunction and its domains assessed by the IIEF.
Of the patients, 332 (93%) were sexually active with a median sexual attempts of 4.6 times per month. Frequency of sexual attempts was inversely related to LUTS severity (P < .001). Advanced age was positively associated with LUTS severity (r = 0.534, P < .001). Sexual dysfunction, defined as IIEF score of 20 and less, was present in 68.2% of the patients. All IIEF domain scores and the overall score were correlated with age (P < .001) and the IPSS (P < .001). In a multivariate analysis, age, diabetes mellitus, and the IPSS were strong independent predictors of the overall IIEF score.
Sexual activity as an important component of the quality of life continues in the majority of men over 50 years. However, their sexual function can be severely affected by LUTS and its severity.
我们的目的是评估50至80岁伊朗男性下尿路症状（LUTS）、年龄与性功能之间的关系。
本研究纳入了357名年龄在50至80岁之间到泌尿外科门诊就诊的男性。分别使用国际前列腺症状评分（IPSS）和国际勃起功能指数（IIEF）问卷来评估下尿路症状和性功能。问卷通过面对面访谈完成。采用逻辑回归模型对性功能障碍的危险因素及其通过IIEF评估的各个领域进行多因素分析。
在这些患者中，332名（93%）有性活动，每月性尝试次数的中位数为4.6次。性尝试频率与下尿路症状严重程度呈负相关（P < 0.001）。高龄与下尿路症状严重程度呈正相关（r = 0.534，P < 0.001）。68.2%的患者存在性功能障碍，定义为IIEF评分≤20分。所有IIEF领域评分和总分均与年龄（P < 0.001）和IPSS（P < 0.001）相关。在多因素分析中，年龄、糖尿病和IPSS是IIEF总分的强有力独立预测因素。
性活动作为生活质量的一个重要组成部分，在大多数50岁以上男性中仍持续存在。然而，他们的性功能会受到下尿路症状及其严重程度的严重影响。
