Several effective treatments exist for erectile dysfunction, ranging from oral medications and exercise to therapy and devices. What works best depends on the underlying cause, which can be vascular, hormonal, psychological, or a combination. Most men see improvement with at least one approach, and current guidelines encourage choosing any treatment that fits your situation rather than strictly following a ladder from least to most invasive.
Oral Medications
Prescription pills that increase blood flow to the penis remain the most common starting point. These drugs work by relaxing blood vessel walls, making it easier to get and maintain an erection when you’re sexually aroused. They don’t create arousal on their own.
Sildenafil produces effective erections in 77% to 84% of men at standard doses. Tadalafil lasts up to 36 hours, earning it the nickname “the weekend pill,” which makes timing less of a concern. Vardenafil is considered more potent at lower doses. All three require a prescription because they interact with certain heart medications and blood pressure drugs, so a provider needs to review your health history first.
These medications work best when the underlying issue is blood flow. If the cause is primarily hormonal or psychological, they may help less on their own.
Exercise and Physical Activity
Aerobic exercise is one of the most effective non-drug interventions, and it works through the same mechanism as medications: improving blood flow. Sessions of 30 to 60 minutes, three to five times per week, produced meaningful improvements in clinical trials. The gains scaled with severity. Men with severe ED saw the largest benefit, with erectile function scores improving by nearly 5 points on a standardized scale, roughly equivalent to the minimum difference a person would actually notice in real life. Men with mild ED saw smaller but still meaningful gains.
Walking, jogging, cycling, and swimming all count. The key is sustained cardiovascular effort, not a specific activity. Beyond the direct vascular benefits, regular exercise also lowers blood pressure, improves cholesterol, reduces stress, and helps with weight management, all of which independently affect erectile function.
Diet and Nutrition
A Mediterranean-style diet, rich in olive oil, vegetables, fruits, whole grains, nuts, and fish with moderate wine intake, is consistently linked to lower rates and severity of ED. Men with the highest adherence to this eating pattern had significantly less ED than those with low adherence. The connection is especially strong in men with type 2 diabetes, where vascular damage is a major contributor.
The mechanism involves several pathways. These foods improve how your body processes fats and blood sugar, boost antioxidant defenses, and increase the availability of nitric oxide, the molecule that signals blood vessels to relax. Tomatoes deserve a specific mention: they contain compounds that reduce inflammation in blood vessels and help normalize blood flow. This isn’t a quick fix, but over months, dietary changes can meaningfully shift erectile function, particularly when combined with exercise.
Therapy for Performance Anxiety
When ED is driven by stress, anxiety, or relationship issues rather than a physical cause, cognitive behavioral therapy (CBT) can be highly effective. In a controlled trial of men with non-organic ED, those who completed CBT showed significant improvements in erectile function, intercourse satisfaction, orgasmic function, and sexual desire compared to a control group. Their self-esteem scores rose substantially, while depression and anxiety scores dropped.
Even when ED has a physical component, anxiety about performance often makes it worse. A pattern develops: one episode of difficulty creates worry, which triggers more difficulty, which increases worry further. Therapy breaks that cycle. Online CBT has shown similar benefits to in-person sessions, making it more accessible. Some men benefit most from combining therapy with medication, using the medication to rebuild confidence while therapy addresses the underlying anxiety.
Low Testosterone
Testosterone levels below 300 ng/dL (the FDA’s threshold for low) are associated with higher rates of ED. If blood work confirms low levels, testosterone replacement can help, though the improvement tends to be modest for erections specifically. In a large trial of 790 men, those using testosterone gel for one year saw an erectile function improvement of about 2.6 points over placebo. The benefit was more pronounced in men with very low levels (under 231 ng/dL) compared to those closer to the borderline.
Where testosterone therapy shines is in improving libido. Many men with low testosterone notice reduced desire first and erectile difficulty second. Restoring hormone levels often improves desire noticeably, and for some men, that’s enough to resolve the erection issues as well. For others, combining testosterone with an oral ED medication produces better results than either alone.
Vacuum Devices
A vacuum erection device (penis pump) uses negative pressure to draw blood into the penis, then a constriction ring at the base holds it in place. It’s a drug-free option that works for most men regardless of the underlying cause. The Mayo Clinic notes these devices carry fewer risks than many other ED treatments.
The main considerations are practical. Using the device interrupts spontaneity, and the erection feels somewhat different because blood is held in place mechanically rather than through natural arousal signals. Some men use a pump to supplement medication on occasions when pills alone aren’t sufficient, or as a bridge while other treatments take effect. If you use one, choose a model with a vacuum limiter to prevent excessive pressure.
Shockwave Therapy
Low-intensity shockwave therapy uses sound waves applied to penile tissue to stimulate new blood vessel growth. In a study of men who had stopped responding to oral medications, 63.5% regained the ability to achieve erections sufficient for sex after a course of 12 sessions spread over several weeks. About half of those men still needed medication alongside the therapy, but the combination worked where medication alone had failed.
A typical protocol involves two sessions per week for three weeks, a three-week break, then another three-week round. The treatment is noninvasive and painless. It’s most effective for ED caused by blood vessel problems rather than nerve damage or hormonal issues. Availability varies, and it’s not yet covered by most insurance plans.
Supplements With Some Evidence
Most supplements marketed for ED lack strong clinical evidence, but Korean red ginseng has more support than most. Across multiple controlled trials, doses of 600 mg three times daily showed benefits for erectile function. Side effects were mild and uncommon: occasional headaches, insomnia, or stomach upset. That said, the evidence is not as robust as it is for prescription medications or exercise, and supplement quality varies widely between brands.
L-arginine, an amino acid that the body converts into nitric oxide, appears in many ED supplements. The theoretical basis is sound since nitric oxide is central to how erections work, and Mediterranean diets that reduce ED do raise arginine levels. However, clinical trial data specifically for L-arginine supplements is limited, and high doses can cause digestive issues.
Combining Approaches
ED rarely has a single cause, which is why combining treatments often works better than relying on one. A man with borderline low testosterone, a sedentary lifestyle, and mild performance anxiety might see partial improvement from exercise alone but much better results by adding therapy or medication. Someone with significant vascular disease might need medication to function now while using diet and exercise to improve the underlying condition over months.
The most important step is identifying what’s contributing to the problem. Blood flow issues, hormone levels, medications you’re already taking (antidepressants and blood pressure drugs are common culprits), stress, and relationship dynamics can all play a role. A provider can help sort out which factors matter most in your case, which makes it easier to choose the right combination of treatments rather than guessing.
