Studies reported that Serenoa repens was effective in relieving lower urinary tract symptoms ( LUTS ) .
This study indicated that Serenoa repens had the same effect in treating BPH compared with tamsulosin in terms of IPSS , QoL , and PVR after at least 6-month treatment cycle , however , the latter had a greater improvement in PV compared with the former .
And Serenoa repens did not increase the risk of adverse events especially with respect to ejaculation disorders and libido decrease
Randomized, double-blind, placebo-controlled trial of saw palmetto in men with lower urinary tract symptoms.
OBJECTIVES To assess the effects of saw palmetto on urinary symptoms , sexual function , and urinary flow rate in men with lower urinary tract symptoms using a double-blind , r and omized , placebo-controlled trial . METHODS The eligible patients were 45 years of age or older and had an International Prostate Symptom Score of 8 or greater . After a 1-month placebo run-in period , 85 men were r and omized to receive saw palmetto or placebo for 6 months . Patients were evaluated using the International Prostate Symptom Score , a sexual function question naire , and by measurement of the 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 ( P = 0.038 ) . The quality -of-life score improved to a greater degree in the saw palmetto group , but this difference was not statistically significant . No change occurred in the sexual function question naire 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 ( P = 0.73 ) . CONCLUSIONS Saw palmetto led to a statistically significant improvement in urinary symptoms in men with lower urinary tract symptoms compared with placebo . Saw palmetto had no measurable effect on the urinary flow rates . The mechanism by which saw palmetto improves urinary symptoms remains unknown
