Myth 1: Erectile dysfunction only affects older men

One of the most common erectile dysfunction myths is that it's an inevitable part of ageing that only affects men over 60. While ED does become more common with age, it can affect men at any stage of adult life [1]. Research shows that erectile difficulties occur across all age groups, with younger men often experiencing ED related to psychological factors such as performance anxiety, stress, or relationship issues [10].

Physical causes become more prevalent with age because conditions like diabetes, high blood pressure, and cardiovascular disease develop over time. However, lifestyle factors—smoking, excessive alcohol, lack of exercise, and obesity—can trigger ED in men in their 20s, 30s, and 40s [2]. The important message is that ED at any age deserves attention, not dismissal as 'normal ageing'.

If you're experiencing erection problems, regardless of your age, speak to a healthcare professional. Early intervention can identify underlying health conditions and prevent them from worsening. At Cured Pharmacy, our UK prescribers assess men of all ages through a confidential online consultation to determine the most appropriate treatment approach.

Myth 2: ED is 'all in your head' and not a real medical condition

Another persistent erectile dysfunction myth suggests that ED is purely psychological and not a legitimate medical issue. In reality, ED has both physical and psychological causes, and often involves a combination of both [1]. Physical factors include reduced blood flow to the penis, nerve damage, hormonal imbalances, and side effects from certain medications. Psychological factors such as anxiety, depression, and stress can also contribute significantly [2].

Importantly, ED can be an early warning sign of cardiovascular disease. The blood vessels in the penis are smaller than those supplying the heart, so reduced blood flow may show up as erection problems before chest pain or other cardiac symptoms appear [10]. This makes ED a potentially valuable indicator of overall health, not simply a psychological concern.

Whether your ED has physical, psychological, or mixed causes, effective treatments are available. Dismissing it as 'just stress' can mean missing important health signals. A GP or specialist can investigate underlying causes through blood tests, blood pressure checks, and a review of your medical history. Treating the root cause—whether that's managing diabetes, adjusting medications, or addressing anxiety—often improves erectile function alongside specific ED treatments.

When to see your GP about ED

You should see your GP if you experience persistent or recurrent erection problems, especially if they're new or worsening. Your doctor will check for underlying conditions such as diabetes, high cholesterol, or cardiovascular disease, which are treatable and important to identify early [1]. This initial assessment is an essential step before starting any ED treatment, as it ensures your overall health is properly managed.

Myth 3: Erectile dysfunction myths include the idea that tablets don't work

Some men believe that ED tablets are ineffective or only work for certain people. In fact, oral PDE5 inhibitors—sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Spedra)—have been extensively studied and proven effective in clinical trials [9]. These medicines work by increasing blood flow to the penis when you're sexually aroused, helping you achieve and maintain an erection suitable for intercourse.

Success rates vary depending on the underlying cause of ED and individual response, but many men find these treatments highly effective when used correctly [2]. The key is understanding that PDE5 inhibitors require sexual stimulation to work—they don't cause automatic erections. Timing matters too: sildenafil works best about an hour before sex, tadalafil can be taken 30 minutes beforehand and lasts up to 36 hours, vardenafil takes 25–60 minutes, and avanafil can work in as little as 15–30 minutes [3][4][5][6].

If one medicine doesn't work well for you, another might. Factors such as food intake, alcohol consumption, and correct dosing all influence effectiveness. A prescriber can help you find the right option and dose. At Cured Pharmacy, our online consultation allows a UK prescriber to recommend the most suitable treatment based on your health, lifestyle, and preferences.

Myth 4: You can't take ED treatment if you have other health conditions

Many men mistakenly believe that having other health conditions automatically rules out ED treatment. While certain medical situations do require caution or make PDE5 inhibitors unsuitable, many men with conditions like diabetes, high blood pressure, or high cholesterol can safely use these medicines under medical supervision [2]. The key is a thorough assessment by a prescriber who reviews your full medical history and current medications.

There are important exceptions. PDE5 inhibitors must never be taken with nitrates (such as GTN spray or isosorbide mononitrate), nicorandil, riociguat, or recreational drugs known as 'poppers', because the combination can cause a dangerous drop in blood pressure [3][4]. Men taking alpha-blockers for prostate symptoms need careful dose adjustment and monitoring. Those on certain HIV medications or antifungal drugs may need lower doses due to drug interactions [3][4].

If you have severe heart disease, very low blood pressure, or have recently had a heart attack or stroke, your doctor will need to assess whether sexual activity itself is safe for you [2]. This doesn't mean ED treatment is impossible—it means careful medical evaluation is essential. Always disclose all your health conditions and medications during any ED consultation, whether online or face-to-face. The prescriber will check for interactions and contraindications to ensure your safety.

Declaring your medications accurately

When completing an online consultation for ED treatment, list every medicine you take, including over-the-counter products, herbal supplements, and recreational substances. This information is confidential and essential for your safety. The prescriber checks every medicine for potential interactions before approving treatment [12]. Never stop or change a prescribed medicine without advice from your doctor or pharmacist.

Myth 5: Lifestyle changes don't make a difference to erectile dysfunction

Another widespread erectile dysfunction myth is that lifestyle factors have little impact on erection problems. Evidence shows the opposite: lifestyle modifications can significantly improve erectile function, sometimes eliminating the need for medication altogether [2]. Smoking damages blood vessels and reduces blood flow to the penis, while excessive alcohol impairs sexual performance and can cause long-term ED [1].

Regular physical activity improves cardiovascular health, which directly benefits erectile function. Exercise helps maintain healthy blood pressure, reduces stress, and improves mood—all factors that support better erections [2]. Maintaining a healthy weight is equally important, as obesity is linked to diabetes, cardiovascular disease, and hormonal changes that contribute to ED [10].

Reducing stress, getting adequate sleep, and addressing relationship issues also play important roles. For some men, combining lifestyle changes with ED medication produces the best results. For others, improving fitness, stopping smoking, and moderating alcohol may be enough to restore function without medication. Your GP or a specialist can provide personalised advice on lifestyle modifications alongside any medical treatment. Even small changes—such as walking 30 minutes daily or cutting down on cigarettes—can make a meaningful difference over time.

Myth 6: Erectile dysfunction myths suggest treatment is embarrassing to access

Many men avoid seeking help for ED because they feel embarrassed or believe the process will be awkward. This myth prevents countless men from accessing effective treatment [1]. In reality, healthcare professionals—GPs, pharmacists, and specialists—discuss ED regularly and approach it as a routine medical issue, not a source of judgement. They understand that ED is common, treatable, and often signals other health concerns that deserve attention.

Online pharmacies like Cured Pharmacy offer a discreet alternative to face-to-face consultations. You complete a confidential health questionnaire reviewed by a UK-registered prescriber, who assesses your suitability for treatment. If appropriate, your medicine is dispensed by our GPhC-registered pharmacy and delivered in plain, unmarked packaging. This process maintains full clinical standards while respecting your privacy and convenience.

Whether you choose to see your GP, visit a pharmacy, or use an online service, remember that seeking help is a positive step. ED can indicate underlying health problems such as diabetes or heart disease, so addressing it early benefits your overall wellbeing [2]. No healthcare professional will judge you for asking about ED—they'll be pleased you're taking your health seriously. Overcoming embarrassment is often the biggest hurdle, but once you take that first step, you'll find the process straightforward and supportive.
