To evaluate quantitatively and qualitatively the degree of sexual dysfunction in an unselected population of men attending a prostate-assessment clinic using a sexual-function inventory, and to ascertain the degree of correlation between sexual dysfunction, urinary symptoms and age.
In all, 168 men with symptomatic BPH attending a prostate assessment clinic were investigated prospectively using the International Prostate Symptom Score (IPSS), BPH Impact Index (BPHII), a measurement of urinary flow rate and residual urine volume, and a sexual function questionnaire. The results were assessed using Spearman's rank order correlation to discern any correlations between the measured variables.
The data from 140 patients were available for analysis; of these, low scores were obtained in 59% for sexual drive, in 56% for erections (with 46% of men satisfying the National Institute of Health criterion for impotence) and in 38% for ejaculation. There was a statistically significant rank order correlation between age and the sexual symptom scores for each of the three categories (sexual drive, erection and ejaculation), but no correlation between age and the problem assessment scores for these domains, suggesting that the older patients are just as bothered by their sexual dysfunction as the younger men. Furthermore, the BPHII scores correlated weakly but significantly with all aspects of sexual function, including overall sexual satisfaction, in contrast to the poor correlation seen with the total IPSS and sexual function scores.
There is a significant number of patients with symptomatic BPH who have sexual dysfunction, with the proportion increasing with advancing age and with the older men still showing a high degree of bother from their symptoms. Sexual function scores were better correlated with BPHII scores than with the total IPSS, although some of the individual IPSS questions correlated well.
使用性功能量表对一家前列腺评估诊所中未经挑选的男性人群的性功能障碍程度进行定量和定性评估，并确定性功能障碍、泌尿系统症状与年龄之间的相关程度。
前瞻性地对一家前列腺评估诊所的168名有症状的良性前列腺增生（BPH）男性患者进行调查，采用国际前列腺症状评分（IPSS）、BPH影响指数（BPHII）、尿流率和残余尿量测量以及一份性功能问卷。使用Spearman等级相关分析结果，以识别测量变量之间的任何相关性。
140名患者的数据可供分析；其中，性欲得分低的占59%，勃起得分低的占56%（46%的男性符合美国国立卫生研究院的阳痿标准），射精得分低的占38%。年龄与三个类别（性欲、勃起和射精）中每一类的性症状评分之间存在统计学上显著的等级相关，但年龄与这些领域的问题评估评分之间无相关性，这表明老年患者与年轻男性一样受到性功能障碍的困扰。此外，与IPSS总分和性功能得分之间的弱相关性相比，BPHII得分与性功能的各个方面（包括总体性满意度）之间存在较弱但显著的相关性。
有相当数量有症状的BPH患者存在性功能障碍，其比例随年龄增长而增加，老年男性仍因症状而有高度困扰。性功能得分与BPHII得分的相关性优于与IPSS总分的相关性，尽管IPSS中的一些个别问题相关性良好。
