Objective: To assess changes in terms of overall satisfaction (OS) and intercourse satisfaction (IS) domains of the International Index of Erectile Function (IIEF) according to the IIEF-EF domain score across different patients ages.

Materials and Methods: Complete data were available for 1010 patients visiting a single academic center in 2005-2017 for erectile dysfunction (ED). Every patient was asked to complete the IIEF questionnaire at first assessment. Patients were categorized as young (<50 yrs), middle-aged (50-64) and old (>=65), respectively. Similarly, patients were categorized as having severe (IIEF-EF<11), moderate (IIEF-EF 11-21), mild (IIEF-EF 22-25) ED or normal EF (IIEF-EF>26) according to the IIEF-EF score, respectively. The one-way analysis of variance tested the mean OS and IS domain scores according to the IIEF-EF categories and within age groups. Linear regression analyses tested the association of both IIEF-OS and IIEF-IS scores with patients’ age and IIEF-EF score.

Results: Overall, 499 (49%), 366 (36%) and 147 (15%) patients were categorized as young, middle-aged and old, respectively. Of all, 32% (327), 28% (281) and 20% (200) of patients had severe, moderate and mild ED, respectively. At linear regression analyses, both age and EF score were linearly associated with either OS and IS score, showing that the older the patient, the higher the increase in the satisfaction scores for the same increase in the EF score (p<0.01). Among old men, mean OS and IS scores were not significantly different between those with mild ED and normal EF (OS: 8.4 vs. 8.4; IS: 10.7 vs. 11.5; p>0.5). Likewise, the increase in the IIEF-EF score was not associated with a significant increase of the OS and IS domain scores among old patients with mild ED (p>0.2). Conversely, both young and middle-aged men showed a linear increase in the satisfaction scores associated with the increase of IIEF-EF score, across all ED categories (p<0.01).

Conclusions: Patients’ perception of EF-related sexual satisfaction changes throughout aging. Our findings suggest that the older the patient the higher the increase of overall and intercourse satisfaction for any EF increase; however, patients of 65 years or older with mild ED may not necessarily benefit from treatment since a further improvement in their sexual satisfaction is not expected.
