Understanding the physiological process of getting an erection can help you look at ED in a whole new light. Your penis has two chambers inside it called the corpora cavernosa. These chambers extend from the head of your penis deep into the pelvis. The insides of these chambers are made of spongy tissue and have the ability to gain blood volume and grow in size. This provides the blood flow needed to keep your tissue healthy. Figure 1. The magic happens when you become aroused.
