Abstract
Aim. To describe age-related male sexual functioning in a representative Dutch general population using internationally accepted and validated questionnaires.
Material and Methods. A random selection of 1404 men from the general populations in the Netherlands were asked to participate. Men primarily completed the International Index of Erectile Function (IIEF), but also provide medical history, details of daily activities, the Body Image Scale, the SF-36 Health Survey, the Hospital Anxiety and Depression Scale, and the Multidimensional Fatigue Inventory. Participants’ representativeness was assessed by comparison with data from the Dutch Central Agency for Statistics and the Dutch Health Monitor. Main outcome measurements were the age-related domain scores of the IIEF.
Results. Responses were obtained from 333 of 1404 men (24%). Participant characteristics were broadly comparable to those of the Dutch population, except for underreporting homosexuals, immigrants, age <40 years and mid-level educations. Overall, 39% of respondents were sexually inactive, and inactivity increased significantly with advancing age. All IIEF domain scores decreased markedly with increasing age, except for overall satisfaction. The prevalence rates of mild and severe erectile dysfunction were 22% and 5%, respectively, and both increased significantly with advancing age.
Conclusion. Four of the IIEF domain scores (i.e., erectile function, orgasmic function, sexual desire, and intercourse satisfaction) decrease with increasing age, whereas the overall satisfaction domain scores remain stable throughout life.
