Dr. Levine reveals what truly works versus myths in treating erectile dysfunction today.

For thousands of men I have treated for erectile dysfunction (ED), and every major therapy available today, here is what truly works, what falls short, and what to consider when other options fail: Dr. Laurence Levine.

In the 1980s, if a man mustered the courage to see a doctor about erection problems, he was often given one piece of well-meaning but deeply unhelpful advice: "Take a vacation and try to relax." The message was clear—the problem was in your head. Stop worrying, and it would vanish. That was the prevailing wisdom at the time. Many doctors believed impotence, as ED was then commonly known, was largely psychological. They were wrong.

As a urologist specializing in erectile dysfunction, I knew even then that most cases had a physical cause, often linked to conditions such as heart disease, diabetes or damage to the blood vessels caused by smoking. But the condition carried enormous stigma, few men came forward for treatment, and misconceptions persisted even within the medical profession.

Four decades on, the picture could hardly be more different. Erectile dysfunction is discussed openly in television commercials and online campaigns. Celebrities and politicians talk openly about using medication for the condition, and there are now more treatment options than ever before. Alongside familiar pills such as Viagra and Cialis are faster-acting medications, combination therapies and even experimental treatments designed to restore blood flow long-term, rather than simply produce an erection.

The result is that many men are left wondering which options genuinely work – and which are simply clever marketing. Over the course of my career, I've prescribed, studied and evaluated most of them. Now I'm sharing what I'd recommend, what I'd avoid, and where I think the future of erectile dysfunction treatment really lies. To appreciate how far we've come, though, it's worth remembering just how limited the options once were.

Dr Laurence Levine trained in urology at Harvard and is Professor of Urology at Rush University Medical Center in Chicago. When I first started my career, we had only a handful of treatments available – and many were cumbersome, invasive or plagued by side effects. We had yohimbine, a stimulant derived from African tree bark that was thought to have aphrodisiac properties and had some evidence behind it. But it could cause anxiety, jitters, insomnia and even heart problems.

There were also injections we gave directly into the side of the penis that dilated blood vessels in the penis, producing an erection on demand. However, they came with risks, including scarring and prolonged erections that would not subside. Vacuum therapy was another treatment option. These devices had been in use since the early 1900s and worked on a simple principle: a plastic tube was placed over the penis and sealed against the pelvis. Suction was then applied to draw blood into the penis, after which a constriction ring was placed at the base to help maintain the erection. It worked, but the devices were cumbersome and, frankly, a bit of a mood killer.

The most effective but most invasive treatment was a penile prosthesis. Early implants, introduced in the 1930s, used rigid materials such as bone, cartilage and plastic. Later, inflatable versions appeared, but these were, and still are, seen as an invasive option of last resort. So, when Viagra appeared in the late 90s, it changed everything. The drug, also known as sildenafil, was originally developed to treat angina chest pain. It works by blocking an enzyme that regulates blood flow, helping blood vessels stay relaxed and improving circulation to the penis.

Sildenafil, originally created to relieve angina chest pain, revolutionized medicine by addressing an unexpected discovery during its early trials. Researchers initially aimed to improve heart blood flow but found many men experienced better erections instead. When the trial ended because it failed against chest pain, patients insisted on continuing use for improved sexual function.

Early concerns suggested the drug might trigger heart attacks, yet this fear proved entirely unfounded. Men with severe heart disease face risks from exertion itself rather than the medication alone. If a man can climb several flights of stairs without significant pain, he is likely fit enough for sex. While priapism was once a worry, it has never occurred when using these drugs in isolation.

Fears about developing tolerance required escalating doses also proved baseless upon investigation. Aging naturally affects blood vessels and health, potentially worsening erectile dysfunction over time. Patients may need dose adjustments, but research indicates one would need ten times the standard daily amount for long-term tolerance to develop. Studies confirm this drug is very safe and effective for most individuals.

Experts now rank it among the most vital medical breakthroughs alongside penicillin and statins. The treatment did more than fix erectile dysfunction; it spawned an entire class of similar medications that changed societal conversations about male sexual health. Millions of men found a condition once shrouded in embarrassment suddenly became discreetly manageable through these new options.

Roughly 65 percent of men with erectile dysfunction experience positive responses to these pharmaceutical interventions. Viagra remains the first-line recommendation due to its low cost and ability to produce strong erections, though side effects like stuffy nose or headaches do occur. Newer alternatives such as Cialis offer fewer adverse reactions while providing extended effectiveness lasting up to 36 hours in some users.

Actor Michael Douglas publicly praised these medications for helping bridge a twenty-five-year age gap with his wife Catherine Zeta-Jones. Unlike Viagra which clears the system within six to twelve hours, daily low-dose Cialis builds up steadily in the body. This steady state allows men to achieve proper responses whenever arousal occurs rather than relying on immediate post-ingestion timing.

Patients can bolster their regimen with an as-needed larger dose if required, though some men prefer daily dosing so they are always ready without relying on precise timing around medication use. Evidence suggests that taking tadalafil daily offers other benefits, such as improving urinary symptoms caused by an enlarged prostate. This daily approach may also enhance the quality of spontaneous nighttime erections; experts believe this helps maintain penile tissue health by improving oxygen delivery. Over time, these improvements could contribute to better overall erectile function, although it is important to note that tadalafil is not a cure for erectile dysfunction and does not reverse underlying disease. There is also emerging evidence linking tadalafil use to improved cardiovascular health.

Vardenafil is another option—a "me-too" medication to Viagra that functions similarly in terms of duration and side effects. More recently, avanafil, sold under the brand name Stendra, was introduced with developers claiming it could work within 15 minutes. In practice, however, onset times can vary between men depending on individual sensitivity and what has been eaten beforehand; food in the stomach can slow the drug's absorption. None of these drugs should be taken by patients using nitroglycerin or similar medications for heart disease, as the combination can cause a dangerous drop in blood pressure. Some patients also report a temporary blue tinge to their vision, particularly with Viagra, caused by the drug's effect on an enzyme in the retina. While harmless and short-lived, this side effect once prompted restrictions on use by pilots due to concerns about visual distortion. For most patients, however, these medications remain both safe and remarkably effective.

Recently, combinations of these drugs in single pills have emerged as an exciting development. The best options contain sildenafil—which offers a bigger benefit than other medications—and tadalafil for longer-lasting effects. Some formulations also include apomorphine, which stimulates the brain's sexual arousal centers, or oxytocin, a naturally occurring hormone involved in feelings of intimacy and bonding. Others may contain PT-141, a peptide with similar effects to apomorphine. Roughly 65 percent of all men with erectile dysfunction, regardless of cause, will see a response to these medications.

Newer treatments like Rugiet Ready and BlueChew have proved effective for some patients who did not get satisfactory results from Viagra or Cialis alone. These oral tablets are designed to dissolve under the tongue, allowing medication absorption through the lining of the mouth rather than the digestive tract, which can lead to a faster onset of action. The downside is the price; at around $7 per pill, they cost roughly ten to 20 times more than generic sildenafil or tadalafil, which can be purchased for well under $1 a tablet with pharmacy discount programs.

Shockwave therapy has emerged over the past decade as another potential treatment for erectile dysfunction. During the procedure, a handheld device delivers thousands of tiny pulses of low-intensity sound energy into the penis, and researchers believe these pulses may trigger repair processes that improve blood flow. However, not all shockwave machines are the same; there are two types: radial and linear. I remain skeptical of radial shockwave therapy. These are the machines most commonly advertised by private clinics, often costing patients thousands of dollars out of pocket, yet I do not believe the evidence shows they work effectively. Linear shockwave therapy is different because it may stimulate the growth of new blood vessels, helping to restore blood flow to the penis. That said, this treatment is not suitable for everyone.

I believe younger men with mild to moderate vascular erectile dysfunction stand to gain the most from new therapies. These individuals still respond well to standard tablets but prefer not to rely on them indefinitely. Conversely, patients suffering severe dysfunction after prostate cancer surgery or advanced vascular disease are unlikely to see significant benefits.

Another experimental option involves Botox injections. The theory suggests that relaxing the muscles surrounding penile blood vessels allows them to widen more easily. This could improve blood flow for some men whose condition stems from excessive muscle tightening rather than nerve damage.

Small studies have reported encouraging results, yet the overall evidence remains limited. Consequently, this treatment has not entered mainstream medical practice. The same situation applies to other therapies now marketed for erectile dysfunction, including platelet-rich plasma, amniotic tissue injections, and various peptides.

While often promoted as cutting-edge solutions, there is little high-quality evidence proving their effectiveness. Before considering any of these treatments, patients should ask what clinical trials support them and who provides them. They must also verify if robust science backs the claims made by marketers. In most cases, the answer is simply not yet.

For men who have exhausted all other options, modern penile implants are no longer a last resort in my view. Instead, they represent an excellent option because devices are more reliable and feel more natural today. They also carry a lower risk of complications than ever before.

This one-hour outpatient procedure boasts high satisfaction rates for both the man and his partner. Infection risks remain low while restoring reliable erections on demand. Importantly, the process does not affect sensation, orgasm, ejaculation, or urination in any negative way.

Despite these advantages, only around 20,000 to 30,000 American men receive an implant each year. I believe this low number is largely due to stigma surrounding the procedure. Many men view it as a desperate final step when they should consider it like a hip replacement instead. It does not change who you are; it simply restores a function that was lost.
