Understanding Erectile Dysfunction:
A Doctor’s Guide to Causes and Treatment
Erectile dysfunction (ED) is the consistent inability to achieve or maintain an erection firm enough for sexual intercourse. It’s not occasional difficulty—it’s a persistent problem affecting your sex life, confidence, and relationships.
How Common Is Erectile Dysfunction?
Approximately 30 million US men experience ED. About 40% of men at age 40 and 70% at age 70 have some degree of ED, yet only 25% seek treatment.
Common Causes of Erectile Dysfunction
Physical Causes: Cardiovascular disease, diabetes, obesity, low testosterone, neurological disorders, medication side effects (blood pressure medications, antidepressants), and lifestyle factors (smoking, excessive alcohol, lack of exercise). Psychological Causes: Depression, anxiety, stress, relationship problems, performance anxiety, past trauma, and body image concerns.
ED as a Warning Sign
- Erectile dysfunction often signals other serious health problems and can be an early warning sign of:
- Heart disease (ED symptoms often appear 3-5 years before cardiac events)
- Diabetes (undiagnosed or poorly controlled blood sugar)
- High blood pressure
- Hormonal imbalances
- Depression
How ED Is Diagnosed
Comprehensive evaluation includes medical history review (medications, chronic conditions, lifestyle habits), physical examination (blood pressure, genital exam, nerve function), laboratory tests (blood sugar, testosterone, thyroid function), and specialized testing when needed.
Symptoms and When to Seek Help
Primary Symptoms:
Difficulty getting or maintaining an erection, reduced sexual desire, erections that aren’t firm enough for penetration.
When to See a Doctor:
ED persists for more than a few weeks, causing stress or relationship problems, accompanied by other symptoms, or you have chronic conditions like diabetes or heart disease.
Treatment Options
Lifestyle Modifications: Weight loss, regular exercise (150 minutes weekly), smoking cessation, alcohol moderation, stress management, improved sleep (7-8 hours), and Mediterranean diet.
Oral Medications (PDE5 Inhibitors):
- Sildenafil (Viagra): 4-6 hours duration
- Tadalafil (Cialis): 24-36 hours duration
- Vardenafil (Levitra): 4-6 hours duration
- Avanafil (Stendra): 6-12 hours duration
- Success rate: 70-80% of men respond well to these medications.
Other Medical Treatments:

- Penile Injections: Highly effective (80-90% success rate)

- Penile Implants: Surgical option with high satisfaction rates (90%+)
