Abstract

Background: The Erectile Function Domain of the International Index of Erectile Function (IIEF6) is inaccurate in assessing erectile function in men who are not practicing sexual intercourse. Improvement through a modification was recently tested on patients after radical prostatectomy. This study examines the application of this modification in a population-based cohort of middle-aged men.

Aim: To assess the feasibility of a modified IIEF6 in a population-based random sample of 50-year old men in Germany.

Methods: 4924 men were included. IIEF6, Erection Hardness Score (EHS), and causes for the absence of sexual intercourse within the previous 4 weeks were assessed. Modified calculation (double weighting of non-intercourse IIEF6 questions) was applied in case of absence due to external circumstances.

Outcomes: Impact of the modification on erectile dysfunction (ED) prevalence and agreement between IIEF6 and EHS in ED classification.

Results: As a result of the modified calculation, ED prevalence in the overall study sample decreased by 6.2% to a rate of 27.2%. Agreement between IIEF6 and EHS was increased from 2.7% to 73.4% in men with no sexual intercourse due to external circumstances.

Clinical implications: An additional inquiry into the reason for the absence of sexual intercourse and modified calculation enhances the accuracy of IIEF6 in evaluating erectile function of the individual man.

Strengths and limitations: This study comprises a large population-based sample. As the study population was exclusively 50-year-old men, results may not be representative of the population average.

Conclusion: A more accurate evaluation of an individual man's erectile function may be achieved by using a modified version of the IIEF6.

IIEF6 的修正计算方法--对中年男性勃起功能更准确的评估。

背景：国际勃起功能指数（IIEF6）的勃起功能域在评估无性交行为的男性的勃起功能时并不准确。最近对根治性前列腺切除术后的患者进行了测试，结果表明通过修改该指标可以改善勃起功能。目的：在德国 50 岁男性人群中随机抽样，评估修改后的 IIEF6 的可行性。方法：纳入 4924 名男性。方法：纳入 4924 名男性，评估 IIEF6、勃起硬度评分（EHS）以及前 4 周内未发生性行为的原因。如果是由于外部原因导致缺失，则采用修改后的计算方法（对无性交的 IIEF6 问题进行双重加权）：结果：修改对勃起功能障碍（ED）患病率的影响，以及 IIEF6 和 EHS 在 ED 分类中的一致性：结果：修改计算方法后，整个研究样本中的 ED 患病率下降了 6.2%，降至 27.2%。在因外部环境而没有性生活的男性中，IIEF6 和 EHS 的一致性从 2.7% 提高到 73.4%：临床意义：对没有性生活的原因进行额外调查并修改计算方法，可提高 IIEF6 评估男性勃起功能的准确性：优点和局限性：本研究包含大量人口样本。优点和局限性：本研究包含了一个基于人口的大型样本，由于研究对象仅为 50 岁的男性，研究结果可能无法代表人口的平均水平：结论：使用改进版 IIEF6 可以更准确地评估男性的勃起功能。
