What is Erectile Dysfunction?
Erectile dysfunction (ED) is the inability to get or keep an erection firm enough for sexual intercourse. It's a common condition that affects millions of men worldwide and can occur at any age.
Medical Definition
Erectile dysfunction is defined as the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. This condition must occur consistently for at least 3 months to be diagnosed as ED.
How Normal Erections Work
To understand erectile dysfunction, it's helpful to know how erections normally occur:
- Sexual arousal: Physical or mental stimulation triggers nerve signals from the brain
- Blood flow increase: Arteries in the penis relax and widen, allowing more blood to flow in
- Trapping blood: The increased blood flow fills the penis's erectile chambers and compresses veins
- Maintaining erection: The trapped blood keeps the penis firm during sexual activity
- After climax: Muscles contract, blood flows out, and the penis returns to its normal state
