An estimated 18 million men in the United States have erectile dysfunction, based on national health survey data showing that about 18.4% of men aged 20 and older are affected. Globally, that number is projected to reach 322 million men by 2025. If you searched this question wondering whether ED is common, the short answer is: extremely.
How Common ED Is by Age
ED becomes significantly more common with each decade of life, but it’s not exclusively an older man’s problem. National Health and Nutrition Examination Survey (NHANES) data from over 2,100 U.S. men found the overall rate was 18.4% for all men 20 and older. That nearly one-in-five figure includes younger men who most people assume aren’t affected.
Studies in men under 40 consistently find rates higher than most people expect. Research pooling data from multiple countries has placed the prevalence in this age group somewhere between 8% and 15%, depending on how strictly ED is defined and how the question is asked. The rates climb steeply after 40, with studies in various populations reporting frequencies anywhere from 20% to well over 50% in men past 60. The Massachusetts Male Aging Study, one of the longest-running investigations into the topic, found that the probability of complete ED tripled between ages 40 and 70.
Most Cases Are Mild
Not all erectile dysfunction looks the same. A study of nearly 2,900 men using a validated questionnaire found that about 32% had some degree of ED, but the vast majority fell on the mild end of the spectrum. Roughly 24% had mild difficulty, 5% had mild-to-moderate issues, 2.2% had moderate ED, and only 1.3% had severe ED where erections were rarely or never possible.
This matters because the phrase “erectile dysfunction” can sound more alarming than the reality for many men. Occasional difficulty getting or maintaining an erection, particularly during stress, fatigue, or heavy alcohol use, is the most common experience. Persistent, complete inability to achieve an erection is comparatively rare.
The Link to Heart Disease and Diabetes
ED doesn’t exist in isolation. It shares the same underlying mechanism as cardiovascular disease: damage to blood vessels and reduced blood flow. In men with type 2 diabetes, about 27% have ED at any given time, and the connection runs deeper than coincidence. Research published in the Journal of the American College of Cardiology found that ED in men with diabetes actually predicted future coronary heart disease events, meaning erection problems often showed up before a heart attack or other cardiac event did.
High blood pressure, high cholesterol, obesity, and smoking all independently increase ED risk through the same vascular pathway. For many men, ED is the first noticeable sign that something is going wrong with their circulatory system, sometimes years before chest pain or other cardiac symptoms develop. This is one of the strongest practical reasons not to dismiss the symptom as just a sexual issue.
Most Men Never Seek Treatment
Despite how common ED is, remarkably few men bring it up with a doctor. Research into help-seeking behavior found that only 32.4% of men with ED had ever initiated a conversation with their physician about it, and only 10.5% said their doctor raised the issue first. The most striking number: just 4.4% had actually sought formal treatment.
That gap between prevalence and treatment is enormous. Many men turn to alternatives instead. About 35% of men in one study had tried traditional remedies, herbal supplements, or over-the-counter products rather than discussing the problem with a healthcare provider. The stigma around ED likely drives much of this avoidance, even though effective prescription treatments have been widely available for over two decades.
Why the Numbers Keep Growing
Global projections estimate 322 million men will experience ED by 2025, a significant jump from earlier estimates of around 150 million in 1995. Several factors are driving this increase simultaneously. Populations are aging, which naturally pushes the numbers up. Rates of obesity and type 2 diabetes are rising worldwide, and both are major contributors. Sedentary lifestyles have become the norm in most developed countries, further compounding vascular risk.
There’s also a detection factor. Men are more willing to report sexual health problems than they were a generation ago, and screening tools have become more standardized. Some of the apparent increase reflects better counting rather than a true spike in new cases. Still, researchers have noted that updated global epidemiological data is overdue, as many of the foundational prevalence studies are now decades old and may underestimate current rates given worsening trends in metabolic health.
The bottom line is that ED affects a far larger share of the male population than most people realize, it often signals broader health issues worth investigating, and the vast majority of men who have it never receive treatment for it.
