Effect of Saw Palmetto Soft Gel Capsule on Lower Urinary Tract Symptoms Associated With Benign Prostatic Hyperplasia: A Randomized Trial in Shanghai, China

Purpose: We determined the effect of Prostataplex™ in men with lower urinary tract symptoms associated with benign prostatic hyperplasia.Materials and Methods: A total of 92 Chinese men between 49 and 75 years old with lower urinary tract symptoms were randomly assigned in this double-blind, placebo controlled trial.
