Erectile dysfunction, commonly called ED, is one of the most common sexual health concerns affecting men. If you sometimes have trouble getting an erection, cannot keep an erection long enough for sex, or have noticed a consistent change in your sexual performance, you are not alone.

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), an estimated 30 million to 50 million men in the United States have erectile dysfunction. ED becomes more common with age, but it is not considered a normal or unavoidable part of getting older.

The good news is that erectile dysfunction is often treatable. Understanding what causes ED is the first step toward finding an appropriate treatment and improving both sexual and overall health.

What Is Erectile Dysfunction?

Erectile dysfunction is the inability to get or keep an erection firm enough for satisfactory sexual activity.

ED can occur in different ways. Some men may be able to get an erection sometimes but not every time they want to have sex. Others may achieve an erection but lose it before or during intercourse. Some men may have difficulty getting an erection at all.

Occasional difficulty getting an erection does not necessarily mean you have chronic ED. Stress, tiredness, alcohol, or other temporary factors can affect sexual performance.

However, when erection problems happen repeatedly, it is worth discussing them with a healthcare professional.

How Common Is ED in the United States?

ED is extremely common among American men.

NIDDK estimates that 30 million to 50 million men in the U.S. experience ED. The condition becomes more common with age, with NIDDK reporting that approximately 40% of men are affected around age 40 and about 70% report ED by age 70.

These numbers show why ED should not be viewed as something embarrassing or unusual. It is a medical condition that can affect men at different stages of life.

More importantly, erectile dysfunction can sometimes provide an important clue about a man's general health.

What Causes Erectile Dysfunction?

ED can have many different causes. An erection depends on healthy blood vessels, nerves, hormones, psychological factors, and adequate sexual stimulation. Problems affecting any of these areas can contribute to erectile difficulties.

1. Cardiovascular and Blood Vessel Problems

Healthy blood circulation is essential for achieving and maintaining an erection.

Conditions such as:

• High blood pressure
• Atherosclerosis
• Heart and blood vessel disease
• High cholesterol
• Stroke

can affect blood flow and contribute to ED.

This is one reason persistent ED should not simply be treated as a sexual problem. In some men, it may be associated with underlying cardiovascular risk factors.

2. Diabetes

Diabetes can affect the blood vessels and nerves involved in sexual function.

Men with diabetes are more likely to develop erectile dysfunction, particularly when blood glucose is not well controlled or when diabetes has contributed to nerve or vascular damage. NIDDK notes that men with diabetes can develop ED significantly earlier than men without diabetes.

Managing diabetes, blood pressure, cholesterol, weight, and physical activity can therefore be an important part of managing ED.

3. Obesity and Excess Weight

Being overweight or having obesity can increase the risk of erectile dysfunction. Excess weight is also associated with conditions such as diabetes, high blood pressure, and cardiovascular disease, which themselves can contribute to ED.

Improving diet, increasing physical activity, and achieving a healthier weight may help improve sexual health for some men.

4. Low Testosterone and Hormonal Problems

Hormonal changes can also contribute to sexual difficulties.

Low testosterone may be associated with reduced sexual desire, fatigue, and erectile problems in some men. Thyroid disorders and other hormonal abnormalities can also affect sexual function.

If symptoms suggest a hormonal problem, a healthcare professional may recommend appropriate testing rather than assuming that testosterone treatment is necessary.

5. Stress and Anxiety

ED is not always caused by a physical problem.

Stress, anxiety, depression, low self-esteem, relationship difficulties, and fear of sexual failure can contribute to erectile dysfunction or make existing ED worse.

For some men, anxiety about sexual performance can create a cycle in which worrying about an erection makes it more difficult to achieve one.

Counseling or sex therapy may be useful when psychological or relationship factors contribute to ED.

6. Certain Medications

Some prescription and over-the-counter medicines can contribute to erectile dysfunction.

Examples include certain:

• Antidepressants
• Blood pressure medicines
• Diuretics
• Antihistamines
• Sedatives
• Hormone medicines
• Certain pain medicines

NIDDK recommends discussing all medicines with a healthcare professional because an alternative medicine or dose adjustment may sometimes be appropriate.

Do not stop a prescribed medication on your own.

7. Smoking and Alcohol

Lifestyle habits can also affect erectile function.

Smoking can damage blood vessels, while excessive alcohol consumption can interfere with sexual function. Recreational drug use may also contribute to ED.

Quitting smoking, limiting alcohol, exercising regularly, and maintaining a healthy weight can support better cardiovascular and sexual health.

Symptoms of Erectile Dysfunction

The symptoms of ED can vary from person to person.

Common signs include:

• Difficulty getting an erection
• Difficulty maintaining an erection
• Erections that are not firm enough for sex
• Losing an erection during sexual activity
• Less consistent erections than previously experienced
• Anxiety about sexual performance

NIDDK identifies three common patterns: being able to get an erection sometimes but not every time, getting an erection that does not last long enough for sex, or being unable to get an erection at all.

Is Erectile Dysfunction a Normal Part of Aging?

No.

ED becomes more common as men get older, but that does not mean erection problems should automatically be accepted as an unavoidable part of aging. NIDDK specifically states that ED is not a routine part of getting older.

Age can increase the likelihood of conditions associated with ED, including cardiovascular disease, diabetes, and hormonal changes. Treating those conditions and addressing lifestyle factors may help improve sexual function.

How Is Erectile Dysfunction Diagnosed?

A healthcare professional will usually begin by discussing your medical and sexual history.

They may ask about:

• When your erection problems began
• How frequently they occur
• Your ability to achieve and maintain erections
• Sexual desire
• Ejaculation and orgasm
• Current medications
• Medical conditions
• Stress, anxiety, or relationship concerns

A physical examination may also be performed. Depending on your symptoms, blood tests or other diagnostic tests may be recommended to identify potential hormonal, vascular, or other medical causes.

Finding the underlying cause is important because treating the cause can sometimes improve ED as well as overall health.

Erectile Dysfunction Treatment Options

The appropriate ED treatment depends on the cause, severity, medical history, medications, and personal preferences.

PDE5 Inhibitors

PDE5 inhibitors are commonly used medications for erectile dysfunction.

Examples include:

• Sildenafil
• Tadalafil
• Vardenafil
• Avanafil

These medicines work by improving blood flow to the penis during sexual stimulation.

Sildenafil is commonly recognized by the brand name Viagra, while tadalafil is commonly known by the brand name Cialis.

These medications do not automatically produce an erection and do not increase sexual desire. Sexual stimulation is still necessary.

Because ED medications can interact with other drugs and medical conditions, they should be used according to a healthcare professional's instructions.

Vacuum Erection Devices

A vacuum erection device is a non-drug option for ED.

The device uses controlled suction to draw blood into the penis and help create an erection. A constriction ring may then be used to help maintain the erection.

Vacuum devices can be useful for men who cannot take certain ED medications or who prefer a non-drug treatment.

Penile Injections

Prescription injectable treatments may be considered when oral ED medicines are ineffective or unsuitable.

These medicines are injected directly into the penile tissue and can produce an erection. Because incorrect use or dosing can cause complications, they should only be used under appropriate medical guidance.

An erection lasting more than four hours requires urgent medical attention.

Penile Implants

For severe ED that does not respond adequately to other treatments, a penile implant may be considered.

Penile implants are surgically placed devices designed to allow a man to create an erection when desired. They are generally considered when other treatment options have not provided satisfactory results or are not appropriate.

Lifestyle Changes That May Help ED

Medication is not the only part of erectile dysfunction management.

A healthier lifestyle can support cardiovascular health and may improve erectile function.

Exercise Regularly

Regular physical activity supports circulation, cardiovascular health, and overall fitness.

Maintain a Healthy Weight

If you are overweight or have obesity, gradual weight management may help reduce some of the health risks associated with ED.

Follow a Heart-Healthy Diet

Diet and sexual health are connected. NIDDK notes that healthy dietary patterns can lower the risk of ED or improve symptoms. Foods such as vegetables, fruits, legumes, whole grains, nuts, seeds, and fish can be part of a balanced eating pattern.

Quit Smoking

Smoking can contribute to vascular problems that affect erectile function. Quitting smoking can benefit both cardiovascular and sexual health.

Limit Excessive Alcohol

Heavy alcohol consumption can contribute to sexual difficulties. Reducing excessive alcohol intake may support healthier sexual function.

Manage Stress

Chronic stress and anxiety can affect sexual performance. Relaxation techniques, counseling, therapy, and open communication with a partner may be helpful depending on the underlying cause.

ED May Be a Sign of Another Health Problem

One of the most important reasons to take persistent ED seriously is that it can occur alongside other health conditions.

Diabetes, high blood pressure, obesity, cardiovascular disease, kidney disease, hormonal disorders, nerve problems, and certain medications can all be associated with erectile dysfunction.

This means an ED evaluation can be an opportunity to look at your overall health—not just your sexual function.

If you have developed persistent erectile problems, especially if you also have cardiovascular risk factors, talk with a healthcare professional.

When Should You See a Doctor About ED?

Consider speaking with a healthcare professional if:

• ED happens repeatedly
• You cannot maintain an erection during sex
• Your erections have become noticeably less firm
• Your sex drive has changed significantly
• ED is affecting your relationship or confidence
• You have diabetes, high blood pressure, or heart disease
• You take medications that may contribute to ED
• You are experiencing other unexplained symptoms

There is no need to feel embarrassed. Healthcare professionals routinely discuss sexual health and can help identify potential causes and treatment options.

Erectile Dysfunction and Your Mental Health

ED can affect more than physical intimacy.

Repeated erection difficulties may lead to embarrassment, frustration, anxiety, low self-esteem, or relationship stress. NIDDK lists emotional and mental health effects among potential complications of ED.

Talking openly with your partner can reduce pressure and misunderstanding. If anxiety or depression is contributing to ED, professional counseling may also be helpful.

Treating the emotional side of ED can be an important part of comprehensive care.

You Don't Have to Deal With ED Alone

Erectile dysfunction is common, treatable, and nothing to be ashamed of.

Whether your ED is related to blood flow, diabetes, medications, hormones, lifestyle factors, stress, or a combination of causes, there are treatment options available.

The most important step is understanding why the problem is happening rather than simply trying increasingly higher doses of medication.

A healthcare professional can help evaluate your symptoms, identify possible underlying conditions, and determine which treatment approach is appropriate for you.

Final Thoughts

Erectile dysfunction? You're not alone.

Millions of men in the United States experience ED, and the condition can occur for many different reasons. Although ED becomes more common with age, it is not simply something men have to accept as part of getting older.

Treatment may include prescription medications such as PDE5 inhibitors, lifestyle changes, counseling, vacuum erection devices, injectable therapies, or other options depending on the individual situation.

If you're experiencing persistent erection problems, don't ignore them or feel embarrassed to ask for help. ED can sometimes be a sign of an underlying health issue, making a medical evaluation an important step toward better sexual and overall health.
