VIAGRA dilates blood vessels of penis when men become sexually excited or stimulated. This results in the penis’ increase of blood flow and vascularity, which leads to a normal erection. VIAGRA is a new approach to the impotence treatment. For a relatively long time VIAGRA (sildenafil citrate), the product by the American company "Pfizer", has been used in medical practice for the impotence treatment in the whole world. The medicine VIAGRA is extremely popular, in spite of its high price. Before the VIAGRA’s introduction, generally either penis’ prosthesis or cavernous drug’s bodies were used. Less spread were vacuum methods and penis’ vascular surgery. In this aspect VIAGRA represents a new approach to the impotence treatment, as the positive effect is achieved after the assumption of just one VIAGRA pill. VIAGRA is meant for men who have a condition known as erectile dysfunction or impotence. Men with such problems do not achieve erection when they become sexually excited. The drug has an effect only as a response to sexual excitement or stimulation. VIAGRA has no impact on reproductive function.
