6mg ethanolic extract of Reishi, once daily, was able to reduce lower urinary tract symptoms (benign prostatic hyperplasia, overactive bladder, incontinence) as assessed by IPSS (International Prostate Symptom Score) self-report. Testosterone was unaffected, and peak urinary flow and residual urine were unaffected despite total symptoms being reduced.
