Cialis is prescribed in cases of male erectile dysfunction. In other cases, many people have found that Cialis improves an already good sex life. They use Cialis as performance enhancer. That is fine as long as people are willing to acknowledge that they have a problem and they like the benefits that result.

Cialis is not an aphrodisiac and it is not for everyone. To understand what is Cialis and how it works, I think that the following information are welcome.

What is erectile dysfunction?
Erectile dysfunction is the inability of the person to either initiate or sustain a penile erection for a sufficient period of time that is needed to attain a sexual gratification. The causes of it may be many for e.g. psychological, hormonal, arterial or muscular.

What is erection?
Erection is a process in which the penis becomes stiff and hard due to augmented blood flow. Erections may happen in response to physical or emotional stimulation, or sometimes an erection happens for no reason at all. Erection also enables sexual intercourse and some other sexual activities, though it is not essential for all of them.

How the erection occurs?
The penis contains two chambers called the corpora cavernosa, which run the length of the organ. When a man becomes aroused, the arteries leading into the penis open up so that pressurized blood can enter corpora cavernosa quickly. The blood creates pressure in the corpora cavernosa, making the penis expand and resulting the erection.

What are the causes of erectile dysfunction?
In most cases, physical causes of erectile dysfunction are very close related to blood flow circulation or nerve impulses to the penis.

How Cialis works?
As I said above, Cialis is not an aphrodisiac. It will not increase sexual drive. It only help people having disorders affecting the blood supply to the pelvis. Under sexual arousement Cialis' action relaxes muscles within the penis. This allows increased blood flow into the corpora cavernosa, very necessary to achieve and maintain a firm erection. Men with erectile dysfunction due to some arterial disorders will benefit the most. It doesn't benefit those with hormonal problems or psychological problems except those with Diabetic neuropathy.
