Abstract
Objectives: To examine the association between α-blocker use and sexual dysfunction among men participating in a population-based cohort of men residing in Olmsted County, MN. Lower urinary tract symptoms (LUTS) in men have previously been associated with sexual dysfunction. The use of α-adrenergic receptor blocking agents results in an improvement in LUTS for many men. If sexual dysfunction and LUTS share a common etiology, α-blocker use might also be associated with a decreased risk of sexual dysfunction. Methods: White men, aged 40-79 years, were randomly selected in 1990 and assessed for α-blocker use and LUTS severity. Sexual function was assessed using the Brief Male Sexual Function Inventory. Men who used α-blockers before any sexual dysfunction were considered "exposed." Hazard ratios and 95% confidence intervals were estimated separately for each sexual function domain using Cox proportional hazard models. Results: Of the 1724 men with a regular sexual partner included in the present study (mean age 57.74 years), 263 (15.3%) reported α-blocker use. α-Blocker use was associated with a decreased risk of sexual dysfunction across all domains for men ≥50 years old (age-adjusted hazard ratio 0.53-0.69). A decreased risk of erectile dysfunction and low libido remained significant only among those using α-blockers who also experienced an improvement in LUTS (P = .01). Conclusions: The use of α-blockers for LUTS was associated with a decreased risk of sexual dysfunction. Improvement in sexual function correlated with the improvement in LUTS more strongly among those using α-blockers.
