What Causes Erectile Dysfunction?
The cause of
erectile dysfunction (
ED) can be anything that disrupts the precise sequence of events that produces an erection. This sequence of events includes:
- Nerve impulses in the brain, spinal column, and area around the penis
- Response in muscles, fibrous tissues, veins, and arteries in and near the corpora cavernosa.
Specific erectile dysfunction causes include:
- Other medical conditions
- Lifestyle
- Surgery
- Injury
- Medicine
- Psychological factors.
The most common cause of erectile dysfunction is damage to the nerves, arteries, smooth muscles, and fibrous tissues -- often resulting from a disease. Diseases that may result in erectile dysfunction can include:
These medical conditions account for about 70 percent of erectile dysfunction cases. Studies show that between 35 percent and 50 percent of men with diabetes experience erectile dysfunction.
Hormonal abnormalities, such as not having enough testosterone, can also result in erectile dysfunction.
