How erections work and how Viagra can help

There are two cylindrical masses of soft erectile tissue in the penis, corpus cavernosa, surrounded by muscle. When these muscles relax, they allow for blood flow into the tissue, resulting in an erection. The muscles relax when a signal from the brain is received, which is sent when sexually aroused.

When a man suffers from Erectile Dysfunction (ED), the signal from the brain that inform the corpus cavernosa to relax is either not there, or limited. What Viagra and over ED drugs do, is relax the walls of your blood vessels. This allows for greater blood flow into the erectile tissue, which of course, results in an erection.

It takes around 30 minutes to an hour for the effect to kick in. The effect will persist for 2 or 3 hours before it begins to decline. I can last in full, up to 5 hours, possibly longer. However, how long it lasts and the effectiveness of the drug, of course like all drugs, can vary depending of variety factors. Of course by dosage, but also age, diet, exercise, general health, or any other medications or substances. Interestingly it can also be effected by the mental state of the user. Anxiety, depression and discomfort can all reduce the effects.

When will a Doctor prescribe Viagra?
