If you are typing at what age does ED start into a search bar, there is usually a reason. Maybe things have not gone to plan lately. Maybe you are in your 30s and assumed this was an "older man's problem". Maybe you are just curious what’s ahead.
Here is the honest answer: there is no single age. Erectile dysfunction (ED) becomes more common as men get older but it can show up in your 20s & 30s too and it is more often linked to something identifiable than most men expect.
In this guide, DirectMeds walks through what the research says about ED at different ages, why the numbers you will see online do not always match, what raises your risk and when it is worth talking to a doctor.
What Age Does ED Start? The Short Answer
ED can occur in different age brackets. The men's health organization of Australia, Healthy Male, defines it as a general but constant incapacity of getting an erection firm enough to have sex, with the usual prevalence being around 30% and growing with age from around 6% of men of 40 to over 60% of men aged over 70.
There is no age at which ED "starts" for everyone. What changes with age is how likely it is and how often there's a physical cause behind it.
ED by Age at a Glance
Age Group | What the Research Shows | What's Often Behind It |
20s and 30s | Less common, but not rare. One cohort of 2,660 young men found 14.2% had ED, mostly mild | Psychological causes are common, but at least 15% to 20% of young men with ED have a physical cause, and causes can be mixed |
40s | Around 6% of men (Healthy Male) | Risk factors such as blood pressure, cholesterol, diabetes and weight start to play a bigger role |
50s and 60s | Prevalence keeps climbing with each decade | Medical conditions and medicines are more often involved |
70 and over | More than 60% of men (Healthy Male) | Often overlooked, but still worth raising with a doctor |
What Does Australian Research Say About Age and ED?
The 45 and Up Study is a large Australian study. This analysis looked at 108,477 men aged 45 and older at a single point in time (a cross sectional design), and excluded men with a history of prostate cancer. About 39.3% reported no ED, so around 60% reported some degree of it. The researchers found that each additional year of age was linked to about 11.3% higher odds of reporting moderate or complete ED.
This figure is about odds across a group of men at one point in time. It does not mean any one man has an 11.3% chance of developing ED each year. It shows that reported ED becomes more common as age increases.
Why Do the Numbers You See Online Vary So Much?
Perhaps you have read that approximately 40 percent of men in their forties suffer from erectile dysfunction (ED). This data comes from the Massachusetts Male Aging Study published in 1994, which included men suffering from ED with any level of severity, including mild cases. Different sources report different figures. Healthy Male’s clinical guide, which summarises the evidence, reports about 6% in men in their forties. The discrepancy in statistics is related to how ED is defined (e.g. mild ED is considered or not), who participated in surveys, the phases of studies, and their geographical location.
Source | Who Was Studied | What It Found |
Healthy Male clinical guide | Australian overview of prevalence | Average prevalence about 30%; about 6% in the 40s, over 60% over 70 |
108,477 Australian men aged 45+ (cross-sectional; men with prostate cancer history excluded) | 39.3% reported no ED; each extra year of age was linked to about 11.3% higher odds of reporting moderate or complete ED | |
US men; counts ED of any degree | About 40% of men in their 40s had some form of ED, rising about 10% per decade |
ED in Your 20s and 30s
Erectile dysfunction is usually regarded as a problem of older men, but according to the review published in 2025, the number of cases of ED observed in men below the age of 40 is being consistently underestimated.
- How common: 14.2% of 2,660 young men surveyed had ED. Most of them, namely 11.3 percent, had mild symptoms of ED, while the rest, or 2.9% reported moderate to severe symptoms.
- Who seeks help: In clinical studies, young males make up about a quarter of men diagnosed with erectile dysfunction. This data has to be regarded as signals of doctor visits rather than accurate, statistically supported information about the issue.
- Psychological causes are prominent and include anxiety about performance, stress, depressive moods, or relationship issues.
- But physical causes are real too: research published in the Asian Journal of Andrology found that at least 15% to 20% of young men with ED had an organic cause. Physical and psychological causes can also occur together. Additionally, a study of 2,292 men under 40 who were seeking help for ED found that 10.7% of the 2,130 who had testosterone testing had low testosterone levels. This reflects men attending a clinic with ED, not young men in general.
Urologists point out in their article published in Translational Andrology and Urology that males aged under 50 usually notice some breakdown of their erectile abilities, for example, being unable to retain the erection for long even though they can achieve erections.
ED in Your 40s and 50s
This is the period during which the factors that cause erectile dysfunction start to accumulate. According to the Mayo Clinic, some common physical causes of ED include heart disease, congested arteries, high cholesterol, hypertension, diabetes, overweight, metabolic syndrome, smoking, low levels of testosterone, issues with sleep and some medications, not to mention stress, anxiety and depression.
Mayo Clinic notes that as men grow older, it may take longer to get an erection and it may not be as firm. But ED is not an inevitable part of aging and ongoing problems are worth having assessed.
ED may also be a sign. Healthy Male website reports that a man can experience ED two to three years before showing cardiovascular symptoms and three to five years before having a major heart event, such as a heart attack or stroke. Thus, it is necessary to check it, but there is no reason for panic.
ED in Your 60s and Beyond
Studies found that erectile dysfunction is most prevalent in older ages, whereby over 60 percent of men aged over 70 suffer from it, according to Healthy Male. There is also an indication by the same handbook that the sexual health of elderly men is often not taken into account either by patients or health service providers. It should be noted that growing older doesn't imply that a person cannot be examined or treated for ED.
What Raises the Risk of ED at Any Age?
Risk Factor | Examples |
Medical conditions | Heart disease, high blood pressure, high cholesterol, diabetes, metabolic syndrome & low testosterone |
Lifestyle | Smoking, being overweight or obese, heavy alcohol use, illicit drug use & poor sleep |
Mental health | Stress, anxiety, depression and relationship difficulties |
Medicines | Some antidepressants, antihistamines and medicines for blood pressure, pain or prostate conditions |
Surgery or injury | Prostate surgery or radiation, pelvic or spinal injuries |
What You Can Do at Any Age
The recommendations of the Mayo Clinic on reducing the risk of ED are very pragmatic and can be applied both in your twenties and sixties:
- Treat conditions such as diabetes and heart disease with a doctor
- Get regular check-ups
- Quit smoking, drinking alcoholic beverages, and using illegal drugs
- Be physically active
- Reduce stress
- Manage mental health.
When to See a Doctor
Any age person should meet with a general practitioner if the problem with erection keeps coming back, becomes concerning or appears together with other diseases such as heart problems, diabetes or some other issues. Do not think that young age or old age makes the condition unimportant.
It is also important to point out that the majority of men do not mention this issue. According to a certain Australian survey, which is referenced by Healthy Male, only 30% of surveyed men reported their problems if suffering from moderate and advanced erectile dysfunction.
Frequently Asked Questions
At what age does ED start?
There is no real answer. It is known though that ED happens mostly after the age of 40 but there are cases when young men in their 20s suffer from ED still.
Can a 20-year-old have erectile dysfunction?
Yes. It might be rare but recent studies show that ED can occur in men in their 20s, though it is less common than in older men.
Is ED a normal part of aging?
Some changes are to be expected. As you get older, the time needed to achieve an erection may increase, and the penis may not become as hard as when you were younger. However, according to the Mayo Clinic, erectile dysfunction is not an inevitable part of aging. Normal changes in erection speed or firmness are not a reason to accept ongoing problems without assessment.
Why am I having ED in my 30s?
There are several potential causes of ED for men in their 30s, including stress and anxiety, depression and relationship problems, drug and alcohol use, and smoking. Physical causes such as low testosterone and blood vessel problems may also be a factor, making an evaluation of ED important.
How common is ED at different ages?
According to Healthy Male, the prevalence of ED increases from 6% among men in their 40s to over 60% among men over 70 years of age. Various studies report slightly different numbers depending on how the studies were conducted and the definitions of ED used.
When should I see a doctor about erectile dysfunction?
If erection issues persist or if they create anxiety or occur with other health issues and symptoms, it is always a good idea to visit a general practitioner. Early evaluation is crucial as erectile dysfunction may be with other medical conditions.
