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.
The veins that would normally drain blood from the penis constrict, trapping the blood inside and maintaining the erection. After ejaculation or when the man is no longer sexually aroused, the arteries narrow, the veins expand, and the blood drains out of the penis. The penis returns to its normal size and is no longer rigid. By Healthwise Staff. Primary Medical Reviewer E. Gregory Thompson, MD-Internal Medicine.
