Erectile dysfunction in men with lower urinary tract symptoms

Objective: To investigate the incidence of erectile dysfunction( ED) in men with lower urinary tract symptoms( LUTS) and the correlation between LUTS and ED.Methods: We enrolled 1 000 men aged 40-80 years with regular sex partners,evaluated their erectile function using IIEF-5,and investigated LUTS among them by International Prostate Symptom Score( IPSS).We studied the relationship between ED and LUTS by univariate conditional Logistic regression analysis.Results: LUTS were found in 42.81% of the men investigated( 426 /995),and ED in 76.18% of the subjects( 758 /995) and 82.16% of those with LUTS( 350/426).Logistic regression analysis revealed a significant relation of ED with aging and LUTS( P 0.01).Conclusion: The incidence of ED is high in men with LUTS and increases with aging and the severity of LUTS.
