ERECTILE DYSFUNCTION

Erectile dysfunction (ED) is the inability to get or keep an erection firm enough to have sexual intercourse. It’s sometimes referred to as impotence, although this term is now used less often.

Occasional ED isn’t uncommon. Many men experience it during times of stress. Frequent ED, however, can be a sign of health problems that need treatment. It can also be a sign of emotional or relationship difficulties that may need to be addressed by a professional.

What causes an erection?
ED can occur because of problems at any stage of the erection process. An erection is the result of increased blood flow into your penis. Blood flow is usually stimulated by either sexual thoughts or direct contact with your penis.

When a man is sexually excited, muscles in the penis relax. This allows for increased blood flow through the penile arteries, filling two chambers inside the penis. As the chambers fill with blood, the penis grows rigid.
