Caverta enables men with impotence to attain the hard state of the male reproductive organ. When a man is aroused, the arteries in the reproductive system of men gets relaxed and widen, allowing more blood to flow into it. As the arteries expand and harden, the veins that normally carry blood away from the male reproductive system gets compressed, restricting the blood flow out of it. With more blood flowing in and less flowing out, the male reproductive organ enlarges and stays on strong for sufficient time. Please understand that this pill is not a hormone or aphrodisiac, you need to have love-making urge to get the effect of caverta tablets. No need to concern about impotency as this medication will prevents its occurrence.
