Erectile dysfunction can be caused by a number of health conditions, but it is almost always the result of another condition, even if the man affected isn’t entirely sure what that condition is. The most commonly seen causes are diabetes, circulatory problems, stress, depression, prostate problems, prior damage to the genitals, and a number of other disorders. Regardless of the cause, erectile dysfunction occurs when there is not enough blood entering the penis for a long enough period of time during arousal. This is where Generic Viagra chimes in. Viagra is comprised mostly of a chemical called sildenafil citrate which works by enhancing a process that occurs naturally in your body. In order to best understand how sildenafil citrate works, it is important to understand how the natural mechanism it enhances works.
When any part of your body receives an external stimulus, your body’s immediate reaction is to send an onrush of blood to that area. This can be seen, for example, if you stub your toe, because the affected area will almost immediately become red with the increased blood flow. With the rush of blood, your body also sends out an enzyme called PDE-5 whose job it is to stop the excess blood flow, because it isn’t healthy to sustain increased blood flow in one area of the body for a prolonged period of time. However, for men with erectile dysfunction, this enzyme is far more of a hindrance than a help because it stops the flow of blood to the penis before a proper erection has been achieved. Viagra works by inhibiting this enzyme, allowing for more blood to enter the penis at a faster rate during arousal. Because it works within your circulatory system rather than your reproductive or nervous systems, sildenafil citrate has virtually no side effects and it has a very limited physical effect on your body because it works with your body’s natural processes rather than against them. For men with erectile dysfunction, Viagra is an effective solution that is safe and easy to take.
