What Causes Erectile Dysfunction?
Sexual stimulation causes the release of chemicals from the nerve endings, present in the penis, to trigger a series of events. These events cause muscles in the penis, which are responsible for erection, to relax. These muscles dictate how much blood flow the penis receives and as the muscles relax, the blood flow goes up, and the erection becomes firm. Some of the most common ED causes are:
- Restricted blood flow (arteriosclerosis).
- Low testosterone.
- Penile scar tissue.
- Antidepressants.
- Heart disorders.
- High blood pressure.
- Obesity.
- Diabetes.
