Kamagra Polo is a generic Viagra drug. It contains the same active ingredient called as sildenafil citrate. The very same Sildenafil citrate is known to increase the amount of blood supply to the pelvic region as it is a vasodilator. Vasodilators are substances that are known in increase the diameter of the arteries for a short while. Kamagra Polo inhibits the action of the agent that makes the man impotent. This agent is called as PDE5, an enzyme that can inhibit the action of cGMP. This cGMP is the main factor that increases the amount of blood flowing into the male reproductive organ. Once PDE5 is inhibited, the action of cGMP is restored, so the organ can feel the excitement and become erect at the right time.
