Int J Impot Res. 2007 Nov-Dec;19(6):564-7. doi: 10.1038/sj.ijir.3901570. Epub 2007 Jun 14.


This randomized-controlled trial examined the efficacy of wonderful variety pomegranate juice versus placebo in improving erections in 53 completed subjects with mild to moderate erectile dysfunction. The crossover design consisted of two 4-week treatment periods separated by a 2-week washout. Efficacy was assessed using International Index of Erectile Function (IIEF) and Global Assessment Questionnaires (GAQ). Of the 42 subjects who demonstrated improvement in GAQ scores after beverage consumption, 25 reported improvement after drinking pomegranate juice. Further, 17 subjects showed preference of one beverage to the other. Subjects were more likely to have improved scores when pomegranate juice was consumed (P=0.058). Although overall statistical significance was not achieved, this pilot study suggests the possibility that larger cohorts and longer treatment periods may achieve statistical significance.
