Erectile Dysfunction: Causes, Symptoms, Treatment, and When to Seek Help
What Is Erectile Dysfunction?
Erectile dysfunction, often called ED, is the inability to get or keep an erection firm enough for satisfying sexual activity.
Having difficulty once in a while is common and usually not a cause for concern. However, if the problem happens regularly or continues for several weeks or months, it may be time to seek medical care.
ED becomes more common with age, but it is not considered a normal part of aging.
How Does an Erection Happen?
An erection depends on several body systems working together.
These include:
- Healthy blood flow to the penis
- Proper nerve function
- Balanced hormone levels
- Sexual stimulation
- A healthy emotional state
Common Symptoms
Erectile dysfunction may include:
- Difficulty getting an erection
- Difficulty keeping an erection during sex
- Erections that are not firm enough for intercourse
- Reduced interest in sexual activity in some men
Some men notice symptoms only occasionally, while others experience them more consistently.
Erectile Dysfunction at a Glance
| Occasional Difficulty | Possible Erectile Dysfunction |
|---|---|
| Happens rarely | Happens frequently |
| Usually related to stress or fatigue | Continues for weeks or months |
| Does not interfere with most sexual activity | Affects confidence or relationships |
| Improves on its own | May require medical evaluation |
Did You Know?
Erectile dysfunction may sometimes be an early warning sign of heart disease. The blood vessels in the penis are smaller than those in the heart, so problems with blood flow may appear there first.
What Causes Erectile Dysfunction?
Many different conditions can contribute to ED.
Common physical causes include:
- Diabetes
- High blood pressure
- High cholesterol
- Heart disease
- Obesity
- Low testosterone
- Side effects of certain medications
- Smoking
- Excessive alcohol use
Emotional factors may also play a role, including:
- Stress
- Anxiety
- Depression
- Relationship difficulties
Many men have both physical and emotional factors contributing to ED.
How Is Erectile Dysfunction Treated?
Treatment depends on the underlying cause.
Common options include:
| Treatment | How It Helps |
| Oral medications (sildenafil, tadalafil) | Improve blood flow to the penis |
| Lifestyle changes | Improve heart and blood vessel health |
| Weight loss | May improve erectile function |
| Regular exercise | Improves circulation |
| Managing diabetes or high blood pressure | Treats underlying causes |
| Counseling or therapy | Helps when stress or anxiety contribute |
For many men, prescription medications known as PDE5 inhibitors are safe and effective when prescribed by a healthcare provider.

Improving your overall health may improve erectile function.
Helpful habits include:
- Exercising regularly
