What is Erectile Dysfunction and What Causes It?

What Is Erectile Dysfunction?

Erectile dysfunction, otherwise known as impotence, occurs when a male is unable to sustain an erection during sexual intercourse. The penile erection occurs when blood enters and is retained within the penis. This is often caused by sexual arousal, where signals are sent from the brain and directed to the nerves within the penis.

What Causes Erectile Dysfunction (Impotence)?

The important cause is cardiovascular disease. Diabetes and neurological problems (such as trauma or prostatectomy surgery), hormonal insufficiencies, and drug side effects can all cause erectile dysfunction.
