Coexisting lower urinary tract symptoms and erectile dysfunction: a systematic review of epidemiological data

Objective: Assess and categorise the available prevalence data on coexistent LUTS and ED in the general population and among individuals consulting a healthcare provider for any reason or when seeking treatment for LUTS and/or ED. Methods: Literature search of English-language articles published during the last 15 years. Results: Of 23 relevant studies identified, 12 used both the International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF) as assessment tools and 11 used alternative approaches. In studies using both IPSS and IIEF, overall prevalence of coexistent LUTS/ED of any severity was not assessable for men in the general population, but rates ranged from 1437% based on alternative assessments. In the general male population, 1329% had moderate to severe LUTS and 835% had moderate to severe ED. In studies using both IPSS and IIEF, overall prevalence of coexistent LUTS and ED of any severity was 7180% among men seeking treatment for LUTS, and 74% based on alternative assessments. Among men who sought treatment for either condition, 67100% had moderate to severe LUTS and 4359% had moderate to severe ED. Coexistence of LUTS and ED increased with age, ranging from 5986% among men aged 40s to 60s in primary care to 79100% in treatment-seeking men with LUTS aged 50s to 70s. Impact on QoL varied, but health-related QoL was generally worse in treatment-seeking men compared with men in the general population. Conclusions: Although less than one-third of middle-aged and older men in the general population have coexisting LUTS and ED, most men seeking treatment for either LUTS or ED have both conditions. Symptom severity and impact on QoL in each condition increase when LUTS and ED coexis
