Introduction. Erectile dysfunction (ED) is a common, and multifactorial medical problem with significant impact on quality of life. Knowledge about baseline potency is highly important in men undergoing treatment for prostate cancer (PCa) as it might influence judgments about impact of treatment and thereby treatment decisions. Aims. To analyze the baseline potency rate of men with clinically localized PCa prior to radical prostatectomy (RP). Furthermore, it was of interest to identify comorbid factors of preoperative ED. Main Outcome Measure. Preavalence of preoperative ED and association between comorbidities and ED in men prior to RP in bi- and multivariable logistic regression analyses. Methods. Retrospective analysis of a large single center cohort of 1,330 evaluable PCa patients who were preoperatively assessed with the abridged 5-item version of the International Index of Erectile Function (IIEF) also described as Sexual Health Inventory for Men. Baseline potency and comorbidity rates, and their distribution were described. The risk of baseline ED associated with age, body mass index (BMI), the presence of hyperlipoproteinemia (HLP), non-insulin-dependent diabetes mellitus (NIDDM), hypertension, and depression were analyzed in bi- and multivariable logistic regression analyses. Results. Using the IIEF-5 cutoff value of 21, 48% demonstrated some degree of ED. Severe, moderate, mild to moderate, mild, and no ED was observed in 9.2, 4.0, 10.2, 24.7, and 52% respectively. In univariable analyses, ED significantly increased according to increasing age, BMI, presence of HLP, hypertension, NIDDM, and depression (P ≤ 0.045). In multivariable analysis, age, BMI, NIDDM, and depression represented independent risk factors of baseline ED (all P ≤ 0.005). Conclusions. It is important to note that one in two men diagnosed with a clinically localized PCa experiences some degree of baseline ED of which 23.4% are moderate to severe prior to local therapy. Age, BMI, NIDDM, and presence of depression represent important independent risk factors of baseline ED.
