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.
One result of this is that the arteries in the penis dilate and the blood can flow into the penis more easily. Another result is that the erectile tissue itself fills with blood. Both of these processes result in an erection. Cialis works by maintaining the level of cGMP in the smooth muscle cells.
