Aspects of Sexual Satisfaction in Men with Erectile Dysfunction: A Factor Analytic and Logistic Regression Approach

Factor analysis detected close relationships among satisfaction questions in IIEF, SEP, and EDITS instruments, each of which, apart from IIEF Q6 (intercourse frequency), appeared to be an independent measure of satisfaction. Cultural differences may explain different satisfaction correlations with baseline ED severity in different regions. Clinicians may make use of the correlation between intercourse frequency (Q6) and satisfaction when prescribing a PDE5 inhibitor for ED, by explaining that the inhibitor should enable more frequent intercourse.
