When a penis becomes hard, it's called an erection. An erection happens when a man is sexually excited, but it can also happen at other random times - especially in younger guys.

Erections happen when blood fills compartments in the penis, making it larger and so stiff that it sticks out from the body.

The penis contains three long cylinders of erectile tissue. Two of the cylinders lie side by side, while the third lies beneath them. The urethra, which is the urine and sperm channel, runs through this lower cylinder. Sexual excitement causes the cylinders to fill with about 100–140 mL of blood and, as they swell, so the penis becomes erect. And as the erectile tissue swells, it squeezes the veins in the penis. These veins normally drain blood away from the penis, so the squeezing action prevents blood flowing away and keeps the penis erect. (Imagine a bath-tub filling with the tap on and a plug in the drain.) After orgasm and ejaculation these events go into reverse, and the penis becomes limp again.

The erection process is a complicated series of psychological and physical interactions: neurotransmitters in the brain are initiated upon arousal, causing nerves to send messages to the vascular system, which directs blood into the penis. Two arteries in the penis supply blood to the corpora cavernosa and surrounding erectile tissue, which become engorged and expand as a result of increased blood pressure.

What is Male Impotence?

Erectile dysfunction (ED), or Male Impotence as it is also known, is defined as the inability to achieve or maintain an erection sufficient for sexual intercourse.

The first step in treating impotence is that the individual understands the cause of impotence including the psychology, physiology and anatomy responsible for the ability to achieve and maintain an erection. If an individual can comprehend cause of impotence than we can better understand the factors that are responsible for impotence and address the questions concerning male impotence treatment treatment.

A lot of men suffer in silence. Finding male impotence drugs for many is too much to bear and they suffer in silence. Male impotence drugs like Levitra can help you get over your condition - provided you know the root causes.
