Modified calculation of the IIEF6-a more accurate assessment of erectile function in middle-aged men.
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.
期刊介绍：
The Journal of Sexual Medicine publishes multidisciplinary basic science and clinical research to define and understand the scientific basis of male, female, and couples sexual function and dysfunction. As an official journal of the International Society for Sexual Medicine and the International Society for the Study of Women''s Sexual Health, it provides healthcare professionals in sexual medicine with essential educational content and promotes the exchange of scientific information generated from experimental and clinical research.
The Journal of Sexual Medicine includes basic science and clinical research studies in the psychologic and biologic aspects of male, female, and couples sexual function and dysfunction, and highlights new observations and research, results with innovative treatments and all other topics relevant to clinical sexual medicine.
The objective of The Journal of Sexual Medicine is to serve as an interdisciplinary forum to integrate the exchange among disciplines concerned with the whole field of human sexuality. The journal accomplishes this objective by publishing original articles, as well as other scientific and educational documents that support the mission of the International Society for Sexual Medicine.
