What causes erectile dysfunction (ED) in men over 50?

Erectile dysfunction (ED) is common after age 50, but that doesn’t mean it’s a natural part of aging. It can be a significant predictor of heart disease. The most common cause of erectile dysfunction in men over 50 is atherosclerosis or hardening of the arteries. Other potential causes include diabetes, obesity, anxiety, and sleep disorders. Lifestyle changes, such as diet, exercise, and quitting smoking, can benefit your heart and erections.

What is erectile dysfunction?

ED, previously referred to as impotence, happens when you can’t get or keep an erection sufficient for a satisfying sex life. That might include erections that don’t last as long as you want or aren’t as firm as you’d like. These issues with erectile function may affect your sexual desire in addition to your ability to have sex.

Erectile dysfunction is the most common sexual dysfunction, affecting approximately 30 to 50 million adult men in the United States—that’s more than half of men aged 40 to 70  (Sooriyamoorthy, 2021).  

Erectile dysfunction and age

ED becomes more common with age. At age 40, around one third of men have ED; this number climbs to 70% by age 70. But these statistics don’t mean that ED is inevitable or is necessarily a natural part of aging. ED often develops in conjunction with other medical conditions that might come with age, like heart disease, high blood pressure, and diabetes (Sooriyamoorthy, 2021). 

What’s the main cause of ED in men over 50?

The most common cause of erectile dysfunction in men over 50 is atherosclerosis, or hardening of the arteries, also known as cardiovascular disease or heart disease. Almost half of men with known heart disease have significant ED (Sooriyamoorthy, 2021). 

As men age, the linings of arteries become less flexible. That means they don’t expand as easily to let more blood flow through when you need it (like while getting an erection). Plaque buildup (or atherosclerosis) can also narrow arteries, meaning less blood can flow to the penis. This reduced blood flow can cause ED as well as heart attacks or strokes. 

Because the penile blood vessels are smaller than those in the heart, they can get affected by atherosclerosis long before you have signs or symptoms of heart disease (e.g., chest pain)—by as much as 10 years. ED can be an early indicator that your blood vessels are not doing well (Sooriyamoorthy, 2021). 

Studies show that young men with ED have a 30% increased risk of developing heart disease over the next 10 years (Pozzi, 2020). In fact, people with ED have over 60% more heart attacks, almost 40% more strokes, and a 25% increased risk of death than those without ED (Sooriyamoorthy, 2021). 

Erectile dysfunction and heart disease share a lot of the same risk factors and symptoms. If you have symptoms of ED, consider getting screened for cardiovascular risk factors like diabetes, high cholesterol, and high blood pressure.

Other causes of erectile dysfunction

ED isn’t only due to cardiovascular issues. Other mental and physical causes can contribute to ED, including (Sooriyamoorthy, 2021):

How can older men avoid ED?

Your erections will be best when you’re healthy. Making simple lifestyle changes—like getting regular exercise, following a healthy diet, quitting smoking, getting enough sleep, and limiting your alcohol consumption—might be enough to lower your risk of ED (Ostfeld, 2021). 

If a healthy lifestyle is not enough, your healthcare provider may recommend medications to treat your ED.

Treatment options for ED

Oral prescription medications for ED are highly effective at improving sexual function. The most commonly prescribed are phosphodiesterase-5 (PDE5) inhibitors like sildenafil (brand name Viagra), tadalafil (brand name Cialis), and vardenafil (brand name Levitra). PDE5 inhibitors work by widening your blood vessels and increasing blood flow to the penis.

Some men have found natural remedies for ED to be effective at improving sexual performance. Some studies have shown that certain supplements (such as DHEA, ginseng, L-arginine, L-carnitine, and yohimbe) may be helpful.
