Research: Eighty-five men 45 years of age or older were recruited for a randomized, double-blind, placebo-controlled trial to assess the effects of saw palmetto on urinary symptoms, sexual function and urinary flow rate. Participants were evaluated using the International Prostate Symptom Score--a sexual function questionnaire--and by measurement of urinary flow rate.
Results: The mean symptom score decreased from 16.7 to 12.3 in the saw palmetto group compared with 15.8 to 13.6 in the placebo group. There was no change in sexual function questionnaire results in either group. The peak flow rate increased by 1.0 mL/s and 1.4 mL/s in the saw palmetto and placebo groups, respectively. Saw palmetto led to a statistically significant improvement in urinary symptoms in men with lower urinary tract symptoms compared with placebo. Saw palmetto has no measurable effect on the urinary flow rates. The mechanism by which saw palmetto improve urinary symptoms remains unknown.
