Can Erectile Dysfunction Be Reversed? What the Research Shows
Yes, erectile dysfunction can sometimes be reversed, especially when it is caused by excess weight, inactivity, smoking or poorly controlled blood pressure, cholesterol or blood sugar. In a two-year Italian trial published in JAMA, about one in three obese men who lost weight and exercised more regained normal erectile function, with no medication. ED caused by nerve damage, surgery or long-standing diabetes is less likely to reverse fully, so a check-up is the first step.
- ED is common: the Massachusetts Male Aging Study found some degree of ED in 52% of men aged 40–70.
- In the Esposito trial, 110 obese men with ED were followed for two years.
- About a third of the lifestyle group regained normal erectile function; the advice-only group barely changed.
- Blood-vessel causes respond best to lifestyle change; nerve and surgical causes respond least.
- Most trials measure change over months, not days.
What does it mean to reverse erectile dysfunction?
Reversing ED means getting reliable erections back without needing treatment every time. It is different from treating ED, where a tablet such as sildenafil helps on the day but does not change the cause. Reversal is only possible when the cause itself can be removed or improved.
That is why the honest answer depends on why erections stopped working. Our main guide, what is possible with natural approaches, explains the full range of causes. This article focuses on the evidence that reversal happens and who it happens for.
What is the strongest evidence that ED can be reversed naturally?
The best-known study is a randomised trial by Esposito and colleagues, published in JAMA in 2004. It followed 110 obese men with ED for two years:
- Half joined an intensive programme: a reduced-calorie, Mediterranean-style diet and more physical activity.
- Half received general advice about healthy eating and exercise.
After two years, about one third of the intensive group had regained normal erectile function, measured with a standard questionnaire. The general-advice group scored about the same as at the start. Men who lost more weight, moved more and saw their blood-vessel health improve were the ones who got better.
Which causes of erectile dysfunction are most reversible?
| Cause | Chance of reversal | What helps |
|---|---|---|
| Excess weight, inactivity | Good | Weight loss, regular exercise — see exercises for ED |
| Smoking, heavy drinking, poor sleep | Good | Stopping smoking, cutting alcohol — see everyday habits |
| Stress and performance anxiety | Good | Counselling, breaking the pressure cycle — see performance anxiety |
| Medicine side effects | Often good | A prescriber review — see medicines that cause ED |
| High blood pressure, cholesterol, early diabetes | Moderate | Better control of the condition — see diabetes, blood pressure and cholesterol |
| Low testosterone | Moderate | Diagnosis and treatment — see low testosterone |
| Nerve damage, prostate surgery, long-standing diabetes | Lower | Medical treatment, rehabilitation |
How long does it take to reverse erectile dysfunction?
Expect months, not weeks. Blood vessels repair slowly. Stopping smoking, improving sleep and cutting alcohol can make a difference within weeks for some men, but the trial evidence for weight loss and exercise is measured over one to two years. A useful rule: give a lifestyle plan at least three to six months before judging it, and see a GP sooner if things get worse.
What does a realistic six-month reversal plan look like?
- Month 1: get checked. Blood pressure, blood sugar, cholesterol and, where advised, testosterone. See talking to a GP about ED.
- Months 1–2: remove the brakes. Stop smoking, keep alcohol within 14 units a week, protect sleep.
- Months 1–6: move daily. Build up to at least 150 minutes of moderate activity a week, plus pelvic floor exercises.
- Months 2–6: eat for blood vessels. A Mediterranean-style pattern — see foods for ED.
- Month 6: review. If erections are not improving, prescribed treatment can be used alongside lifestyle change. Using it is not failure.
Thinking about a supplement?
Some men try a nitric-oxide supplement while they work on lifestyle changes. Before you spend money, read our evidence-first review of Nitric Boost: ingredients, research and price.

Can erectile dysfunction be reversed naturally?
Sometimes. When ED is linked to weight, inactivity, smoking or stress, lifestyle change can restore erections. A JAMA trial found about a third of obese men regained normal function after two years of diet and exercise.
Can ED be reversed permanently?
If the cause is removed and stays removed, erections can stay normal. If the cause returns, such as weight regain or smoking, ED can return too.
How long does it take to reverse ED with exercise?
Usually months. Trials measure improvement over one to two years, though some men notice changes sooner.
Can ED from diabetes be reversed?
Better blood sugar control can help, especially early on. Long-standing diabetes can damage nerves and vessels, so full reversal is less likely and medical treatment is often needed.
Is it worth seeing a doctor if I want a natural approach?
Yes. A check-up finds the cause, which decides whether natural reversal is realistic, and can pick up conditions such as diabetes or heart disease early.
