Erectile dysfunction is treatable at every level of severity, and most men see improvement with one or a combination of approaches. Treatment isn’t a rigid ladder you climb from least to most invasive. The American Urological Association recommends shared decision-making, meaning the right treatment is whichever one fits your situation, preferences, and health profile.
Lifestyle Changes That Improve Erections
Before or alongside any medical treatment, physical activity, weight management, and quitting smoking can meaningfully restore erectile function. These aren’t vague “be healthier” suggestions. The numbers are specific and worth knowing.
In one clinical trial, men who combined their medication with at least three hours per week of aerobic exercise saw normal erectile function return at nearly double the rate of men using medication alone: 78% versus 39% after three months. Exercise improves blood flow, reduces inflammation, and raises testosterone, all of which directly affect erection quality.
Weight loss matters too, especially for men carrying extra weight around the midsection. Losing roughly 10% of body weight has been linked to increased testosterone, better blood vessel function, and measurable gains on standardized erectile function scores. In a year-long trial of over 300 overweight men with type 2 diabetes, the group that focused on diet and exercise saw their erectile function scores improve significantly compared to the control group.
Smoking is a well-established cause of vascular damage to the penis. In a prospective study, at least 25% of men who quit smoking saw their erectile function improve within one year. None of the men who kept smoking experienced the same benefit.
Oral Medications
The most widely used treatments are oral medications that work by relaxing blood vessels in the penis, making it easier for blood to flow in during arousal. The four available options all work through the same mechanism but differ in timing and duration.
- Sildenafil (Viagra): Taken about an hour before sex. Doses range from 25 mg to 100 mg.
- Tadalafil (Cialis): Also taken about an hour before sex, with doses from 5 mg to 20 mg. Tadalafil is unique because it lasts significantly longer, up to 36 hours, and can also be taken as a low daily dose so you don’t need to plan around it.
- Vardenafil (Levitra): Taken an hour before sex in doses of 10 mg to 20 mg.
- Avanafil (Stendra): Can work in as little as 15 minutes, making it the fastest-acting option.
These medications don’t create an automatic erection. You still need arousal for them to work. Most men find that one of the four works well, though it sometimes takes a few tries to find the right medication and dose.
The one absolute safety rule: these medications cannot be combined with nitrate drugs, which are commonly prescribed for chest pain and heart conditions. The combination causes a severe, potentially dangerous drop in blood pressure and can reduce blood flow to the heart. If you take any form of nitrate medication, these drugs are off the table entirely, and your doctor will direct you toward other options.
Low Testosterone
Low testosterone contributes to ED in some men, but it’s not the cause for most. Testing involves a simple blood draw, taken in the early morning when levels peak. A total testosterone level below 300 ng/dL, confirmed on two separate mornings, is the diagnostic threshold. If your levels are normal, testosterone therapy won’t help your erections.
When testosterone is genuinely low and causing symptoms like reduced desire, fatigue, and difficulty with erections, replacement therapy can improve all three. It’s available as gels, injections, or patches. For many men with both low testosterone and ED, combining testosterone therapy with an oral medication works better than either alone.
Therapy for Psychological ED
Erection problems in younger men are frequently driven by anxiety, stress, depression, or relationship issues rather than blood flow problems. Performance anxiety in particular creates a cycle: one failed erection leads to worry, which triggers the next failure.
Cognitive behavioral sex therapy (CBST) directly targets this cycle. In a pilot study comparing CBST to sildenafil in men with non-organic ED, both treatments produced similar improvements in erectile function scores and depression. Where therapy pulled ahead was in reducing anxiety, which is often the core driver. Eight weeks of sessions proved more effective than shorter courses. For men whose ED is rooted in psychological factors, therapy addresses the actual cause rather than working around it.
Penile Injections
If oral medications don’t work or aren’t safe for you, self-injection therapy is the next common step. A tiny needle delivers medication directly into the side of the penis, producing an erection within 5 to 15 minutes that lasts long enough for intercourse. The idea sounds worse than the reality. The needle is very small, and most men get comfortable with the process quickly.
The most commonly used injection medication has an overall success rate of about 80%. The main drawback is that 20% to 40% of men report some pain at the injection site. More serious side effects include prolonged erection lasting more than four hours (about 4% of cases) and gradual scar tissue formation at injection sites (about 8%). Both are manageable with proper technique and medical guidance.
Vacuum Erection Devices
A vacuum device is a plastic cylinder that fits over the penis. A pump creates suction that draws blood into the shaft, and a constriction ring slides to the base to hold the erection in place. It’s non-invasive, requires no medication, and works regardless of the underlying cause.
In a long-term study following over 200 men, 70% were still using the device regularly after more than two years. Patient satisfaction was 84%, and partner satisfaction was 89%. Over 90% rated erection quality as satisfactory for hardness, length, and circumference. Men reported going from about once per month of successful intercourse before the device to about four times per month after, a gain that held beyond the first year. The device takes some getting used to, and the erection can feel slightly different since blood flow is mechanically maintained rather than naturally sustained. But for men who want to avoid medication or surgery, it’s a reliable option with a long track record.
Penile Implants
Surgery is typically considered when other treatments have failed or aren’t suitable. A penile implant (prosthesis) is a device placed inside the penis during a procedure that takes about an hour. The most common type is a three-piece inflatable implant: a pump placed in the scrotum, a fluid reservoir in the abdomen, and two inflatable cylinders inside the penis. Squeezing the pump transfers fluid into the cylinders, creating a rigid erection. A simpler semi-rigid (malleable) rod option is also available, which keeps the penis firm at all times and is manually positioned.
Satisfaction rates are consistently among the highest of any ED treatment. A broad literature review covering studies from 1989 to 2018 found that 85% of patients were satisfied, with quality of life improving substantially for both patients and partners. More recent reviews put satisfaction rates at 80% to 90% or higher. In one comparative study, 96% of patients reported overall satisfaction, and 80% of partners were happy with the decision. Once healed, the implant is completely concealed and undetectable.
The tradeoff is that implant surgery is permanent. The natural erectile tissue is altered during placement, so if the implant is removed later, natural erections generally won’t return. Mechanical failure rates are low with modern devices, but replacement surgery may eventually be needed after 10 to 15 years.
Supplements With Some Evidence
Two supplements have at least modest clinical backing. L-arginine, an amino acid that helps produce nitric oxide (the same molecule targeted by prescription ED drugs), showed meaningful improvement in a meta-analysis of 10 randomized trials. Doses in successful studies were typically around 5 grams daily. Side effects were minimal, mostly limited to headaches and mild stomach issues. One trial using an L-arginine-based supplement saw erectile function scores nearly double over six months.
Red ginseng (sometimes labeled Korean ginseng) has also shown promise. Six out of seven randomized trials in a meta-analysis reported statistically significant improvements in erectile function. Its active compounds appear to work by boosting nitric oxide production, similar to L-arginine. Side effects are mild.
Neither supplement is as potent or as well-proven as prescription medications. But for men with mild ED or those looking to complement other treatments, they carry low risk and some documented benefit.
