title: Prevalence and pathogenesis of impotence in one hundred uremic men.
abstract: In a study of dialysis patients 79% of men complained of sexual dysfunction and 61% erectile impotence following uremia and the onset of regular dialysis therapy. Plasma testosterone levels were significantly higher in patients treated by continuous ambulatory peritoneal dialysis (p = 0.001) but the incidence of sexual dysfunction was not different from patients treated by hemodialysis. Although follicle-stimulating hormone levels were higher (p = 0.001) and penile blood pressure index levels lower (p less than 0.05) in patients with impotence, sexual function was not improved by exogenous testosterone, and vasculogenic impotence was identified in only 6% of patients. These findings suggest that a major component of uremic impotence is unrelated to primary testicular failure or penile vascular insufficiency.
