Male erectile dysfunction

Erectile dysfunction, often called ED, happens when the penis does not get enough blood flow to become firm, or cannot stay firm long enough for sex. The penis works like a sponge that fills with blood when you are sexually aroused, but if that blood flow is blocked or the nerves aren't signaling correctly, the sponge stays soft.

It is important to know that this is a very common physical condition and not a personal failure. Because the process of getting an erection involves your heart, blood vessels, nerves, and hormones, ED is often just a sign that your body needs a little extra attention.
