The amount of blood in the penis increases sixfold during an erection. The blood filling the corpora cavernosa compresses and then closes off the openings to the veins that normally drain blood away from the penis (see Figure 4). In essence, the blood becomes trapped, maintaining the erection.
An erection is the result of increased blood flow into the penis. Blood flow is usually stimulated by either sexual thoughts or direct contact with the penis. When a man becomes sexually excited, muscles in the penis relax. This relaxation allows for increased blood flow through the penile arteries.
