Erectile Dysfunction: Causes and Treatment Options
Erectile dysfunction is a symptom, not a diagnosis. Identifying the underlying cause is what makes treatment effective.

- ED becomes more common with age but is not an inevitable part of aging.
- Blood-flow problems, nerve issues, hormones, medications and psychological factors can all contribute.
- ED can be an early signal of cardiovascular or metabolic disease, which is why evaluation matters.
- PDE5 inhibitors such as sildenafil and tadalafil are the most commonly prescribed first-line medications.
- PDE5 inhibitors are dangerous with nitrates and require provider screening.
Erections depend on a coordinated sequence: arousal signals from the nervous system, healthy blood vessels that can dilate, sufficient blood flow, and a hormonal environment that supports desire. A problem anywhere in that chain can present as erectile dysfunction.
The main categories of cause
| Category | Examples | Why it matters |
|---|---|---|
| Vascular | Atherosclerosis, high blood pressure, high cholesterol, diabetes | The most common contributor; also the reason ED can precede cardiac diagnoses |
| Hormonal | Low testosterone, thyroid disorders, elevated prolactin | Often affects desire as much as function; requires lab evaluation |
| Neurological | Diabetic neuropathy, spinal injury, pelvic surgery | Signal transmission is impaired rather than blood flow |
| Medication-related | Some antidepressants, blood pressure medications, others | Timing that lines up with a new prescription is a clue |
| Psychological and lifestyle | Anxiety, depression, relationship stress, alcohol, smoking, poor sleep | Frequently coexists with physical causes rather than replacing them |
How ED is evaluated
- History: onset, whether it is situational or constant, morning erections, libido, medications
- Cardiometabolic screening: blood pressure, glucose or A1c, lipids as clinically indicated
- Hormonal labs when symptoms suggest it, typically morning testosterone
- Mental health and relationship context, which are often decisive
Because ED shares causes with heart disease, a legitimate evaluation looks at cardiovascular risk rather than only writing a prescription. Chest pain, shortness of breath on exertion or new exercise intolerance need medical attention.
Treatment categories
PDE5 inhibitors
Sildenafil and tadalafil improve blood flow response during arousal. They do not create arousal on their own. They must not be used with nitrate medications, and they need provider screening for cardiovascular status and interacting drugs.
Treating the underlying driver
Managing blood pressure, glucose, lipids, sleep apnea, alcohol use and smoking often improves function directly, and improves the response to medication.
Hormonal and psychological care
If labs and symptoms indicate hypogonadism, hormone evaluation is part of the plan. When anxiety or relationship factors dominate, medication alone tends to underperform compared with combined care.
Our guide comparing sildenafil and tadalafil covers the practical differences between the two most common medications.
Frequently asked questions
- Is ED always a sign of a serious problem?
- Not always, but because it shares risk factors with cardiovascular and metabolic disease, it is worth a proper evaluation rather than self-treatment.
- Does ED mean my testosterone is low?
- Not necessarily. Low testosterone is one possible contributor among several, and it more often affects desire than mechanical function.
- Can ED be reversed?
- Many contributors are modifiable, and many men improve with treatment of the underlying cause. Outcomes are individual and cannot be guaranteed.
