There is no single “best” treatment for erectile dysfunction because the right option depends on what’s causing it, how severe it is, and what fits your life. That said, oral medications work for the majority of men and are the most common starting point. For those who need more, treatments range from injections and devices to surgery, each with strong success rates. Here’s how the options compare so you can have an informed conversation with your doctor.
Oral Medications: The Most Common Starting Point
Oral ED medications all work the same way: they relax blood vessels in the penis so blood flows in more easily when you’re aroused. They don’t create arousal on their own. The main differences come down to how fast they kick in and how long they last.
Sildenafil (Viagra) is the most widely studied option, with effective erections reported in 77 to 84 percent of men at standard doses. It typically works within 30 to 60 minutes and lasts four to six hours. You take it on demand, and a heavy or fatty meal can slow absorption.
Tadalafil (Cialis) is often called the “weekend pill” because its effects can last up to 36 hours. That longer window gives more flexibility around timing. It can also be taken as a low daily dose, which means you don’t have to plan around a pill at all. For men who want spontaneity, tadalafil is often the preferred choice.
Vardenafil (Levitra) and avanafil (Stendra) round out the options. Avanafil is the fastest-acting, sometimes working in as little as 15 minutes, and tends to produce fewer side effects like headache and flushing. All four medications have similar overall effectiveness, so the “best” one often comes down to your preferences around timing and side effects.
One hard rule: if you take nitrate medications for chest pain (like nitroglycerin), oral ED drugs are off the table. Both nitrates and these medications lower blood pressure, and combining them can cause a dangerous drop. Make sure your doctor knows every medication you’re on before prescribing.
Lifestyle Changes That Make a Real Difference
Exercise is one of the most underrated treatments for ED. A review of 11 randomized trials involving more than 1,000 men found that 30 to 60 minutes of aerobic exercise, three to five times a week, improved erectile function in men with mild to moderate ED. Walking, cycling, swimming, or jogging all count. The benefit comes from improved blood vessel health, lower blood pressure, and better blood flow, the same mechanisms that medications target.
Weight loss matters too, especially for men carrying extra weight around the midsection. Excess body fat lowers testosterone, increases inflammation, and damages blood vessels. Losing even 5 to 10 percent of your body weight can improve erections noticeably. Cutting back on alcohol, quitting smoking, and improving sleep are all changes that compound over time. These aren’t alternatives to medication for everyone, but for men with mild ED, they can be enough on their own, and for men on medication, they make it work better.
When Low Testosterone Is Part of the Problem
Not all ED is caused by low testosterone, but when levels fall below about 300 ng/dL (the threshold used by the FDA), men are significantly more likely to have erection problems along with low sex drive, fatigue, and mood changes. A simple blood test can check your levels.
Testosterone replacement helps most in men whose levels are clearly low. Research shows the greatest improvement in erectile function when levels are below about 230 ng/dL before treatment. Men with borderline levels (between 230 and 346 ng/dL) still see some benefit, but less. Testosterone comes as gels, patches, or injections. It’s not a standalone fix for most ED, but when low testosterone is contributing, correcting it can make oral medications work better or restore function that pills alone couldn’t.
Therapy for Performance Anxiety and Stress
ED that’s driven by anxiety, relationship problems, or stress responds well to psychological treatment, often cognitive behavioral therapy (CBT). The process typically involves identifying the thought patterns that fuel performance anxiety, gradually reducing avoidance of sexual situations, improving communication with your partner, and rebuilding confidence through structured exercises.
The strongest evidence supports combining therapy with medication rather than choosing one or the other. Research from the European Society of Sexual Medicine found that pairing medical treatment with psychotherapy produces better outcomes and fewer dropouts, even when there’s a clear physical cause. If you notice that your ED started during a stressful period, is worse with a partner but not alone, or comes and goes unpredictably, anxiety is likely playing a role.
Penile Injections: Higher Success Rate, Bigger Commitment
For men who can’t take oral medications or don’t get enough response from them, self-injection therapy is the next step. You use a very fine needle to inject a medication directly into the side of the penis about 5 to 20 minutes before sex. It sounds intimidating, but most men get comfortable with it quickly.
The success rates are remarkably high. In a six-month study of 683 men, 94 percent of injections resulted in erections firm enough for sex, and both the men and their partners rated the experience as satisfactory about 87 percent of the time. Mild penile pain occurred at some point in about half of users, though it only happened with 11 percent of individual injections. More serious issues like prolonged erections (5 percent of men) or scarring (2 percent) are uncommon but worth knowing about.
There’s also an intraurethral pellet option, where a tiny medicated pellet is inserted into the tip of the penis instead of injecting. It’s less effective than injections but avoids needles entirely.
Vacuum Devices: No Medication Required
A vacuum erection device (sometimes called a penis pump) uses suction to draw blood into the penis, then a soft ring placed at the base holds the blood in place during sex. It’s one of the few options that involves no drugs or surgery.
Studies show that about 90 percent of men can achieve rigidity sufficient for penetration. The tradeoff is convenience and naturalness. Erections typically last around 18 minutes with the ring in place, and satisfaction rates tend to drop over time. In one study, about 41 percent of men and 45 percent of partners were still satisfied at six months, with premature loss of rigidity during sex being the most common complaint. Vacuum devices work best for men in stable relationships who are comfortable with the process and want to avoid medication entirely.
Shockwave Therapy: A Newer Option
Low-intensity shockwave therapy uses sound waves applied to the penis to stimulate new blood vessel growth. Unlike every other ED treatment, which works around the problem, shockwave therapy aims to actually restore the underlying blood flow so natural erections can return.
In a study of 55 men who had already failed oral medications, 63.5 percent were able to achieve erections firm enough for penetration after completing 12 treatment sessions over several weeks. About 18 months later, most still needed oral medication alongside the shockwave benefit, but the combination worked where pills alone had not. Younger men (under 45), those with ED for less than two years, and those with moderate rather than severe ED responded best. The treatment is painless and has no reported side effects, but it’s still considered relatively new and isn’t yet part of standard guidelines everywhere.
Penile Implants: The Last Resort With the Highest Satisfaction
Penile implant surgery is typically reserved for men who haven’t responded to other treatments. A surgeon places a device inside the penis that allows you to produce an erection mechanically. There are two main types: inflatable implants, which use a small pump hidden in the scrotum to fill cylinders in the penis with fluid, and malleable (semi-rigid) rods that can be positioned up or down.
What’s surprising about implants is how satisfied men are afterward. At one year, quality-of-life scores across functional, relational, social, and personal domains are consistently high. Men with inflatable devices report higher functional and overall satisfaction than those with malleable implants, largely because inflatable models look and feel more natural. The surgery is permanent and irreversible, which is why it’s positioned as a final option, but for men who’ve exhausted other avenues, it often provides the most reliable results of any treatment.
Choosing the Right Approach
The American Urological Association’s guideline emphasizes that every man should be informed about all available options, not just the least invasive ones. Shared decision-making is the recommended approach: you and your doctor weigh the benefits, risks, and what matters most to you personally. Some men want the simplest pill. Others want to avoid medication entirely. Some prioritize spontaneity, while others care more about reliability.
Most men start with lifestyle changes and oral medication. If those don’t work well enough, the conversation moves to injections, devices, or shockwave therapy. Surgery sits at the end of that path but carries the highest long-term satisfaction for the men who choose it. The best ED treatment, in practice, is the one that fits your body, your relationship, and your life.
