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.
When men are sexually stimulated, nitric oxide is released; resulting in an activation of an enzyme called the guanylate cyclase that relaxes blood vessels and allows blood to fill up in the erectile tissues consequently the male organ achieves an erection.
