Why erectile dysfunction in your 70s is so common

As men age, changes in blood vessels, nerves, and hormone levels make erections more difficult to achieve and maintain [1]. By the time you reach your 70s, the prevalence of ED increases significantly, with studies showing that more than 50% of men in this age group experience some degree of erectile difficulty [10].

The most common physical causes include reduced blood flow due to atherosclerosis (narrowing of the arteries), which is often linked to high blood pressure, high cholesterol, and diabetes [2]. These conditions damage the small blood vessels and nerves that control erections. Prostate problems, including benign prostatic hyperplasia (BPH) and treatments for prostate cancer, can also contribute to ED.

Medications commonly prescribed in your 70s—such as beta-blockers, diuretics, and antidepressants—can have ED as a side effect [2]. Psychological factors, including anxiety, depression, and relationship changes, can play a role too, though physical causes are more common in older age groups. Understanding the underlying cause is the first step towards finding the right treatment.

How erectile dysfunction in your 70s differs from younger men

ED in your 70s is more likely to be caused by multiple overlapping health conditions rather than a single issue [2]. Younger men often experience ED due to psychological factors or lifestyle habits, whereas older men typically have a combination of cardiovascular disease, diabetes, and medication side effects.

The good news is that treatments such as PDE5 inhibitors (sildenafil, tadalafil, vardenafil, and avanafil) remain effective in older men, provided they are used safely and under medical supervision [1][2]. However, because men in their 70s are more likely to be taking other medications—particularly for heart conditions—it is essential that a prescriber reviews your full medical history and current medicines before starting ED treatment.

Older men may also benefit from longer-acting options such as tadalafil, which can last up to 36 hours and allows for more spontaneity [4]. Daily low-dose tadalafil is another option that can provide continuous support. The key is finding a treatment that fits your health profile, lifestyle, and preferences, and this is where a thorough consultation with a healthcare professional is invaluable.

The importance of a full health check

If you are experiencing ED for the first time, or if it has worsened recently, it is important to see your GP [1]. ED can be an early warning sign of cardiovascular disease, as the same processes that narrow the arteries in the heart can affect blood flow to the penis. A full health check can identify conditions such as diabetes, high blood pressure, or high cholesterol that need treatment in their own right. Addressing these underlying conditions can improve both your general health and your erectile function.

Safe and effective treatments for erectile dysfunction in your 70s

The first-line treatment for ED in men of all ages, including those in their 70s, is oral medication known as PDE5 inhibitors [2]. These include sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Spedra). They work by increasing blood flow to the penis when you are sexually stimulated, making it easier to achieve and maintain an erection [3][4][5][6].

Sildenafil is taken about one hour before sex and is effective for around four hours [3]. Tadalafil can be taken on-demand (at least 30 minutes before sex, with effects lasting up to 36 hours) or as a daily low dose [4]. Vardenafil works similarly to sildenafil, while avanafil has a faster onset of around 15–30 minutes [6]. All require sexual stimulation to work and should be taken no more than once a day.

These medicines are generally safe and effective in older men, but they are not suitable for everyone [2]. They must not be taken with nitrates (such as GTN spray or isosorbide mononitrate), nicorandil, riociguat, or recreational drugs known as 'poppers', as this combination can cause a dangerous drop in blood pressure [3][4]. If you take alpha-blockers for prostate symptoms or blood pressure, you will need to start on a lower dose of PDE5 inhibitor and be monitored carefully. A prescriber will review your full medical history and current medications during an online consultation to ensure treatment is safe for you.

Lifestyle changes that can help manage ED

Alongside medication, lifestyle changes can make a significant difference to erectile function, especially in your 70s [1][2]. Regular physical activity improves cardiovascular health, blood flow, and mood, all of which support better erections. Even moderate exercise such as walking, swimming, or cycling can help.

Maintaining a healthy weight reduces the risk of diabetes and cardiovascular disease, both major contributors to ED [2]. A balanced diet rich in fruits, vegetables, whole grains, and lean protein supports vascular health. Reducing alcohol intake is important, as heavy drinking can worsen ED and interact with medications. Smoking damages blood vessels and significantly increases the risk of ED; stopping smoking at any age can improve erectile function [1].

Managing stress and maintaining good mental health are also important. Anxiety and depression can contribute to ED, and talking therapies or counselling may help [2]. Open communication with your partner about your concerns and expectations can reduce performance anxiety and strengthen your relationship. Combining lifestyle changes with medical treatment often gives the best results.

The role of underlying health conditions

Treating underlying health conditions such as diabetes, high blood pressure, and high cholesterol can improve erectile function [2]. Good control of blood sugar levels in diabetes, for example, can reduce nerve and blood vessel damage. Your GP can review your medications to see if any are contributing to ED and may be able to switch you to an alternative. Never stop or change a prescribed medicine without medical advice.

When to speak to a doctor about erectile dysfunction in your 70s

You should see your GP if you are experiencing ED for the first time, if it has worsened suddenly, or if it is affecting your quality of life or relationship [1]. ED can be an early sign of cardiovascular disease, diabetes, or other health conditions that need investigation and treatment. Your GP can arrange blood tests, check your blood pressure, and review your medications.

You should seek urgent medical help if you experience an erection lasting more than four hours (priapism), sudden loss of vision or hearing, or chest pain during sexual activity [3][4]. These are rare but serious side effects that require immediate attention. If you have any concerns about your heart health or whether sexual activity is safe for you, discuss this with your GP before starting ED treatment.

If you are already taking nitrates, nicorandil, riociguat, or have been advised to avoid sexual activity due to heart problems, PDE5 inhibitors are not suitable for you [2][3]. Your doctor can discuss alternative treatments such as vacuum devices, alprostadil (Vitaros cream or Caverject injection), or referral to a specialist. The important thing is to seek help rather than suffer in silence—ED is common, treatable, and nothing to be embarrassed about.

What to expect from your consultation

During an online consultation with Cured Pharmacy, you will be asked about your general health, any medical conditions (such as heart disease, diabetes, high blood pressure), and all medicines you currently take, including over-the-counter and herbal products. This information is reviewed by a UK-registered prescriber who will decide whether ED treatment is safe and appropriate for you. If you have complex health needs or take multiple medications, the prescriber may recommend that you see your GP for a face-to-face assessment first. This is to ensure your safety and the best possible outcome.
