Association between lower urinary tract symptoms and sexual dysfunction in Taiwanese men.
The study investigated the association between lower urinary tract symptoms (LUTS) and sexual dysfunction in ageing men. It was a cross-sectional study in an unselected consecutive sample of 398 men aged >40 years attending a urology clinic. LUTS and sexual function were assessed by validated symptom scales, including the International Prostate Symptom Score (IPSS) and the International Index of Erectile Function-5 (IIEF-5). Clinically the severity of total and obstructive IPSS showed no significant correlation with age, but irritative IPSS is statistically correlated with age (P < 0.05). The prevalence of moderate to severe ED (IIEF-5 < 12) was significantly associated with LUTS severity (P < 0.05) and the severity of IIEF-5 correlated significantly with age (P < 0.01). A consistent inverse correlation was found between IIEF-5 and IPSS severity across the age groups, with the strongest effect within aged 60 to 69 years (r = -0.286, P < 0.01). The irritative IPSS showed a significant correlation with IIEF-5 severity across all age groups. These results reveal a significant correlation between LUTS and the severity of ED, especially on the irritative domain.
