How it Works

To achieve an erection blood flow to the ercectile tissue increases causing these cylinders to fill with blood which then results in the penis becoming erect.

Erectile Dysfunction can happen for many different reasons such as medical conditions or as a side effect of an existing medication. These can all cause an interference with the natural erection process. When the penis cannot fill with enough blood the man cannot have an erection. This is called erectile dysfunction if it becomes a frequent problem. Erectile Dysfunction means blood cannot flow to the erectile tissue and prevents an erection from being achieved. Taking Viagra increases the flow of blood to the erectile tissue meaning an erection is achieved and maintained.

Viagra eliminates the PDE (phosphodiesterase) that is decomposing the cGMP (Cyclic Guanosine Monophosphate), so cGMP builds up in the penis and has a larger effect on the artery walls. The larger the amount of cGMP the greater the blood flow, the greater the blood flow the greater degree of the erection.
