Erectile Dysfunction Treatment Options: What Works

Oral PDE5 inhibitors — sildenafil and tadalafil — are the most commonly prescribed first-line ED treatment. Lifestyle changes, testosterone evaluation, vacuum devices, and other therapies also play a role. A urologist can identify the underlying cause and guide the most effective combination.

What is erectile dysfunction and how common is it?

Erectile dysfunction is the persistent difficulty getting or keeping an erection firm enough for satisfying sexual activity. It becomes more common with age, but it is not an inevitable part of aging. Cardiovascular disease, diabetes, high blood pressure, obesity, depression, and certain medications are all established contributors. Because ED can be an early marker of cardiovascular risk, a clinician who evaluates it is often looking at your overall health picture, not just one symptom.

What medications are used to treat ED?

PDE5 inhibitors — sildenafil, tadalafil, vardenafil, and avanafil — are the first-line medical treatment for most men with ED 1. They work by increasing blood flow to erectile tissue in response to sexual stimulation. They do not create an erection on their own; arousal is still required. A systematic overview of meta-analyses confirmed their effectiveness across a broad population 2. Key practical differences:

  • Sildenafil (Viagra): typically taken 30–60 minutes before activity; lasts about 4–6 hours; affected by food
  • Tadalafil (Cialis): can be taken as a low daily dose or as-needed; lasts up to 36 hours; less affected by food
  • Vardenafil / Avanafil: similar on-demand profiles to sildenafil with modest timing differences

PDE5 inhibitors are contraindicated with nitrate medications (used for chest pain) because the combination can cause a dangerous drop in blood pressure. Your clinician will review your other medications before prescribing.

For men who do not respond to oral medications, injectable medications (alprostadil), vacuum erection devices, intraurethral suppositories, or penile implant surgery are additional options described in the AUA guideline 1.

Does low testosterone cause ED, and should it be tested?

Low testosterone (testosterone deficiency) can reduce sexual desire and contribute to ED, though it is not the most common cause. The AUA recommends measuring morning total testosterone in men with ED, particularly if libido is also reduced 3. If testosterone is confirmed low on two separate tests and symptoms are present, testosterone replacement therapy (TRT) may improve both desire and erection quality. TRT should not be started without testing and a clinical evaluation — testosterone supplementation when levels are normal has not been shown to improve ED and carries its own risk profile.

What lifestyle changes genuinely help?

Several modifiable factors have good evidence supporting improvement in erectile function:

  • Cardiovascular fitness: Regular aerobic exercise improves endothelial function, which underlies erection quality. The relationship between ED and cardiovascular health means that what is good for the heart is often good for erections.
  • Weight loss: Obesity is a significant risk factor. Even modest weight reduction can improve ED in overweight men.
  • Stopping smoking: Smoking damages blood vessel walls throughout the body, including the penile vasculature.
  • Reducing or stopping alcohol: Heavy alcohol use is a recognized cause of ED.
  • Managing blood pressure and blood sugar: Hypertension and diabetes are two of the strongest drivers of ED. Better control of these conditions often improves erectile function.
  • Mental health treatment: Anxiety and depression contribute to ED. Addressing them — through therapy, medication, or both — can resolve ED when psychological factors are primary.

Are there non-medication, non-surgical options?

Yes. A vacuum erection device is a non-invasive option that draws blood into the penis mechanically and uses a constriction ring to maintain the erection. It has no drug interactions and is suitable for men who cannot take oral medications. Penile rehabilitation programs — including pelvic floor physical therapy — show promise in men with ED after prostate cancer treatment, though the evidence for broader populations is still developing. Low-intensity shockwave therapy is an emerging approach being studied in certain men; it is not yet standard practice and is not widely covered by insurance.

When should I see a urologist vs. my primary care clinician?

A primary care clinician can initiate the evaluation — checking testosterone, blood glucose, blood pressure, and lipids — and prescribe first-line PDE5 inhibitors when appropriate. A urologist is the right specialist for ED, particularly when:

  • Oral medications have not worked
  • ED followed prostate surgery or pelvic radiation
  • There is penile pain, curvature (Peyronie's disease), or anatomical concerns
  • You are considering a penile implant

Gale can help you prepare for either type of appointment — organizing your medication list, flagging relevant health history, and finding the right provider.

Common questions

Can ED medications be taken every day?

Low-dose daily tadalafil is approved for daily use and is also used to treat benign prostatic hyperplasia (BPH). Other PDE5 inhibitors are generally taken as needed. Your urologist or primary care clinician can help determine which approach fits your situation.

Do natural supplements work for ED?

Supplements marketed for ED — including L-arginine, panax ginseng, and others — have limited, low-quality evidence. None are FDA-approved treatments, and some interact with medications. The AUA guideline does not endorse supplements as standard therapy. Lifestyle changes have stronger evidence than supplements.

Is ED always a physical problem?

Not always. Psychological contributors — performance anxiety, depression, relationship stress, past trauma — can cause or significantly worsen ED. A thorough evaluation considers both physical and psychological factors, and addressing the psychological side (often through therapy) can resolve ED when it is the primary driver.

Can ED be a sign of heart disease?

Yes. ED and cardiovascular disease share the same underlying mechanism — impaired blood vessel function — and ED can appear years before a heart attack or stroke in some men. A new ED diagnosis warrants a cardiovascular risk review, which your clinician can coordinate.

When to seek prompt care

  • —Sudden loss of erection ability accompanied by chest pain, shortness of breath, or pain in the arm or jaw — call 911
  • —A prolonged, painful erection lasting more than 4 hours (priapism) is a urological emergency — go to an emergency department immediately
  • —Significant penile pain or sudden penile curvature (possible penile fracture) — seek emergency care
  • —ED after a pelvic or perineal injury

For prolonged painful erection or chest pain with ED, call 911 or go to the nearest emergency department.
