All good things come to an end

All good things come to an end. This statement, unfortunately, applies to erection as well. Erection comes over almost right after ejaculation, because ejaculation is a signal to stop the release of cyclic AMP. But even before your erection will be over by itself because of ejaculation, there will be a series of chemical reactions in the penis directed to protect the organ from exhaustion.

Malicious enzyme that counteracts erectogenic cycle of the cyclic AMP or neutralizes the cyclic AMP, is called 5-phosphodiesterase, or PDE5. This enzyme is another point of application of Viagra due to which it is able to prolong the time of erection.

The active ingredient of Viagra links with PDE5 preventing the contact of the enzyme with the cyclic AMP. Thus the release of new molecules of the cyclic AMP is not interrupted, and the total number of the cyclic AMP continues to grow supporting the arteries to be dilated, and the penis continues to receive new portion of the blood. As a result, many men whose arterial blood flow in the area of the penis was not intense enough and they could not achieve a full erection before, now can overcome these disorders.

Whatever the cause of the erectile dysfunction is, whether any psychological problem or dysfunction of cardiovascular or nervous system responsible for erection, Viagra most often can help overcome any difficulty and to obtain qualitative and full erection.

Understanding how Viagra works helps to think about erectile dysfunction as just one of the symptoms which is manifested due to various mental and physical illnesses with disorders of blood vessels or nerves in the genital area. And as, for example, Tylenol eliminates pain in the joints without healing from the arthritis, Viagra can help you to get rid of impotence without interfering the cause of the prior disease. We know this is more than enough for many men.
