Erectile Dysfunction (ED): Causes, Symptoms, and Treatment Options

What is erectile dysfunction?

Erectile dysfunction (ED) is the consistent difficulty getting or maintaining an erection sufficient for sexual activity. Occasional difficulty can be normal, especially during stress or fatigue. ED becomes a clinical concern when it is persistent, affects confidence or relationships, or signals an underlying health issue.

ED is common — affecting millions of men — and is not simply a normal part of aging. Many men benefit from evaluation and treatment when symptoms persist.

Common causes of ED

ED often results from a combination of physical and psychological factors. Physical causes include cardiovascular disease, diabetes, high blood pressure, obesity, hormonal changes, nerve conditions, and certain medications. Psychological contributors include stress, anxiety, depression, and relationship strain.

Because ED can be an early marker of cardiovascular disease, a thorough health evaluation is important — not only for sexual function but for overall wellness.

How ED is evaluated

Evaluation typically includes a private discussion of symptoms, medical history, lifestyle factors, and relevant health conditions. A clinician may review medications, blood pressure, and cardiovascular risk. In some cases, lab work or additional testing may be recommended.

Online care can be appropriate for many men with straightforward ED when a licensed clinician determines that remote evaluation is safe. Complex cases may require in-person follow-up.

Treatment approaches

Treatment depends on the underlying cause and individual goals. Options may include lifestyle changes (exercise, weight management, sleep, reducing alcohol), addressing psychological factors, and FDA-approved medications such as sildenafil or tadalafil when clinically appropriate.

Medications work by enhancing blood flow to the penis but require sexual stimulation to be effective. They are not aphrodisiacs and do not work for everyone. A clinician determines whether medication is appropriate based on your health profile.

When to seek care

Consider speaking with a clinician if ED persists for several weeks, causes distress, affects your relationship, or occurs alongside other health changes. Early evaluation can identify treatable causes and reduce long-term health risks.
