Saw Palmetto is widely used to promote prostate health. The prostate gland is responsible for production of seminal fluid and ejaculation. As men age, the prostate gland naturally enlarges. This leads to lose of ejaculation control and reduced blood circulation to genitals. A derivative of testosterone called DHT is responsible for prostate enlargement. Saw Palmetto prevents the conversion of testosterone to DHT, thus reducing enlargement, improving genital blood circulation, and raising testosterone levels. The combined result is better sex drive, erection, and ejaculation control.
