Erectile dysfunction is one of the most common sexual health concerns among Canadian men. It affects about 40% of men by age 40 — and up to 70% of men over 70. The good news is that effective treatments are available. This article explains what causes erectile dysfunction, how doctors diagnose it, and what your treatment options look like.

What Is Erectile Dysfunction?

Erectile dysfunction means a man cannot get or keep an erection firm enough for sexual activity. It can range from mild to severe. In milder cases, a man may achieve a partial erection but not maintain it long enough to reach orgasm.

In more severe cases, no erection occurs at all. However, severity is somewhat personal. What bothers one man may not concern another. If it is affecting your quality of life or your relationship, it is worth talking to your family doctor.

Erectile dysfunction is not just an older man’s problem. It can happen at any age. In younger men, the cause is often psychological. In older men, the cause is more often physical, or organic.

Common Causes of Erectile Dysfunction

There are many possible causes of erectile dysfunction. Doctors generally group them into physical causes and psychological causes. Often, both factors play a role at the same time.

Physical Causes

Several health conditions are strongly linked to erectile dysfunction. These include:

  • Diabetes: High blood sugar can damage the nerves and blood vessels needed for an erection.

  • High blood pressure (hypertension): This reduces blood flow throughout the body, including to the penis.

  • Atherosclerosis: This is the hardening and narrowing of arteries. It restricts the blood flow needed for an erection.

  • Neurological conditions: Diseases affecting the nervous system can interfere with the signals needed for an erection.

  • Surgery or injury: Surgeries for prostate cancer, rectal cancer, or spinal procedures can damage nearby nerves and blood vessels.

  • Radiation therapy: Radiation for prostate cancer can also cause erectile dysfunction.

  • Pelvic fractures or genital injuries: Physical trauma to the pelvic region can lead to erectile problems.

Medications That Can Cause Erectile Dysfunction

Some common medications can cause erectile dysfunction as a side effect. These include certain blood pressure medications, antidepressants, and other psychiatric drugs. If you think your medication may be contributing to the problem, speak with your family doctor before stopping anything on your own.

Lifestyle Causes

Smoking is a major risk factor. It worsens the effects of diabetes, high blood pressure, and atherosclerosis on your blood vessels. Quitting smoking can meaningfully improve erectile function over time.

Heavy alcohol use can also cause erectile dysfunction. It does so by changing hormone levels, often linked to liver disease. Moderate alcohol consumption, however, does not typically cause this problem.

Psychological Causes

In younger men especially, stress, anxiety, depression, and relationship issues can all lead to erectile dysfunction. In these cases, psychological treatment is often the most effective approach. Therefore, addressing mental health is just as important as addressing physical health.

Diabetes and Erectile Dysfunction

Diabetes is one of the most common physical causes of erectile dysfunction. Unfortunately, this connection is often overlooked. Men with diabetes who experience erectile problems should speak directly with a urologist if their endocrinologist has not addressed it.

Managing blood sugar levels carefully can help reduce the severity of erectile dysfunction in diabetic men. Health Canada provides resources on managing diabetes and its complications, including sexual health effects.

How Is Erectile Dysfunction Diagnosed?

Diagnosing erectile dysfunction involves more than just describing your symptoms. Your doctor will ask about your medical history, your medications, and your lifestyle habits. A physical exam is also standard.

Testosterone Testing

Checking testosterone levels in the blood is not a routine test for all men with erectile dysfunction. However, many doctors include it as part of a full assessment. Low testosterone is more often suspected when the physical exam reveals unusually small testicles.

In older men with confirmed low testosterone, testosterone replacement therapy may help. However, it is not effective for all men with erectile dysfunction. It works best when a true hormonal deficiency is the underlying cause.

The International Index of Erectile Function

This is a 15-question questionnaire that men fill out themselves. Each answer is rated on a scale of 1 to 5. The total score helps the doctor assess how severe the erectile dysfunction is.

This tool is also useful for measuring whether a treatment is working over time. In addition, researchers often use it in clinical trials for new erectile dysfunction treatments.

Nocturnal Erection Testing (RigiScan)

Healthy men typically have erections during sleep. A RigiScan is a device that measures whether these nighttime erections occur. If they do, it suggests the physical structures are working — and the cause may be psychological.

This test is especially helpful in younger men to tell apart psychological causes from physical ones. It is rarely used as a routine test, but it can be an important tool in certain cases. For example, it is sometimes used in legal medicine to determine erectile capability.

Treatment Options for Erectile Dysfunction

The good news is that erectile dysfunction is treatable. There are several effective options, and your doctor will recommend one based on your age, health, and the likely cause. Most Canadian doctors start with the least invasive options first.

Oral Medications

Sildenafil (commonly known by the brand name Viagra) is currently the most widely used treatment for erectile dysfunction. It works by increasing blood flow to the penis during sexual arousal. It does not cause an erection on its own — sexual stimulation is still required.

According to the Mayo Clinic’s guide to erectile dysfunction, oral medications are effective for the majority of men and are generally the first line of treatment. Other similar medications include tadalafil (Cialis) and vardenafil (Levitra).

Penile Injections

If oral medications do not work, the next step is often self-injection therapy. The man injects a medication directly into the penis before sexual activity. This produces an erection within 10 to 15 minutes — even without sexual stimulation.

This option requires some training and comfort with the process. However, it is effective for many men who do not respond to oral medication.

Vacuum Erection Devices

A vacuum erection device uses gentle suction to draw blood into the penis, creating an erection. A ring is then placed at the base of the penis to maintain it. This method has a success rate of 70 to 80%, including in men for whom oral medications have not worked.

Penile Implants

Penile prosthesis surgery is one of the most effective treatments available. It has a success rate of over 90%. A surgeon places a device inside the penis that allows the man to control when and how long he has an erection.

The infection rate for this procedure is about 2 to 3%. When infection does occur, the implant must be removed. Revision surgery after infection is significantly more difficult. Therefore, this option is typically reserved for men who have not responded to other treatments.

Psychological Treatment

For men under 50 where psychological causes are most likely, therapy with a psychologist or sex therapist is often the most appropriate first step. Furthermore, even when the cause is physical, counselling can help address anxiety or relationship strain that often develops alongside erectile dysfunction.

Vascular Surgery

In rare cases, surgery to improve blood flow to the penis is considered. This is the least common treatment option and is only appropriate for specific patients. Most doctors exhaust all other options before recommending this route.

When to See a Doctor

If erectile dysfunction is affecting your confidence, your relationship, or your quality of life, it is time to talk to someone. You do not have to wait until things are severe. This is a medical condition — not a personal failing.

Start by booking an appointment with your family doctor. If you do not have one, a walk-in clinic can provide an initial assessment and referral. Your provincial health plan covers most diagnostic tests and referrals to urologists or other specialists.

Also see a doctor right away if you develop new abdominal pain alongside erectile dysfunction. While erectile dysfunction itself does not cause abdominal pain, that combination could signal another condition that needs prompt attention.

The World Health Organization’s sexual health resources also emphasize that sexual health is an important part of overall well-being — and that seeking help is always appropriate.

Frequently Asked Questions About Erectile Dysfunction

At what age does erectile dysfunction usually start?

Erectile dysfunction can start at any age, but it becomes more common as men get older. Studies show that about 40% of men experience it by age 40, and up to 70% by age 70. In younger men, the cause is often psychological rather than physical.

Can erectile dysfunction be cured permanently?

In some cases, erectile dysfunction can be resolved by treating the underlying cause — for example, managing diabetes better, stopping a medication, or addressing anxiety. In other cases, ongoing treatment is needed to manage the condition. Your doctor can help determine what is realistic based on your specific situation.

Is erectile dysfunction covered by provincial health plans in Canada?

Diagnostic tests, specialist referrals, and most medical appointments related to erectile dysfunction are covered by provincial health plans. However, prescription medications like sildenafil (Viagra) may not be fully covered depending on your province and whether you have supplemental drug coverage. Check with your provincial drug benefit programme for details.

Can lifestyle changes improve erectile dysfunction?

Yes, lifestyle changes can make a real difference. Quitting smoking, reducing alcohol intake, exercising regularly, and managing conditions like diabetes and high blood pressure can all improve erectile dysfunction. These changes work best when the cause is primarily related to blood vessel health.

Does low testosterone always cause erectile dysfunction?

Not always. Low testosterone is one possible cause of erectile dysfunction, but most men with this condition have normal testosterone levels. Testosterone replacement therapy is only effective when a true hormonal deficiency is confirmed through blood testing. Other causes are far more common.

What is the most effective treatment for erectile dysfunction?

The most effective treatment depends on the underlying cause. Oral medications like sildenafil are the most commonly used first-line treatment for erectile dysfunction and work well for most men. For those who do not respond to medication, options like vacuum devices, penile injections, or surgical implants offer high success rates.
