What Causes ED?

Why erectile dysfunction (ED) happens
ED can be caused by things like stress or fatigue. But a lot of times, ED is not something that you can control. That’s because it’s often due to a physical problem that affects your blood flow.

Usually when a man is sexually aroused:

1. The brain sends an impulse telling the arteries in the penis to widen.
2. As a result, more blood flows to the penis.
3. When this happens, the penis expands and hardens. This causes an erection.

When a man has ED, the nerves or blood vessels in the penis don’t work properly. This prevents blood from flowing to the penis. And that can prevent an erection.
