What is erectile dysfunction (ED) and how does it happen?
Erectile dysfunction means a man finds it hard to get or keep an erection firm enough for sex. A good erection needs nerves, hormones, blood flow and being turned on. If something blocks one of those for example, if blood vessels are narrow, or nerves are damaged, then an erection might not work well.
How common is erectile dysfunction (ED), and at what age does it start?
Erectile dysfunction (ED) is quite common. Many men get mild erection problems sometimes. It becomes more likely as men get older. For example, men in their 40s have fewer issues than those in their 60s or 70s, but problems can happen at almost any age.
Can erectile dysfunction (ED) be a sign of other health problems (like heart disease or diabetes)?
Yes. erectile dysfunction (ED) can sometimes be a clue that something else is going on in the body. Things like high blood pressure diabetes, high cholesterol, or heart problems can make it harder for blood to flow well. When blood flow is weak, erections can be weak too. If you have ED, it's smart to get checked by a doctor.
What causes erectile dysfunction (ED) in young, healthy men?
Even if you're young and seem healthy, erectile dysfunction (ED) can happen. Causes can be: feeling very stressed, being tired, drinking a lot of alcohol, taking certain medicines, feeling anxious about sex, or even problems like being overweight or not sleeping well. Sometimes it can be a mix of things.
Can stress, anxiety, or depression cause erectile dysfunction (ED)?
Yes. The brain plays a big role in erections. If you feel worried, stressed or sad, it can make it harder to “turn on” physically. Sometimes people still have erections in the morning but not with their partner - that can be a sign the issue is more about how you think or feel than something physical. It’s okay to ask for help.
What treatments are available for ED in the UK?
Treatments include tablets such as sildenafil, tadalafil, vardenafil and avanafil, which help increase blood flow to the penis. Other options include vacuum devices, injections, testosterone treatment if levels are low, and counselling when stress or anxiety plays a role.
How long do ED tablets take to work?
ED tablets usually work within 30 to 60 minutes, though this varies. Tadalafil can last up to 36 hours, and avanafil may work within 15 minutes. A heavy meal or alcohol can slow down the effects, so timing and routine can make a difference.
When should I see a clinician about ED?
You should consider seeing a clinician such as your GP if ED keeps happening, lasts for several months or affects your confidence or relationships. You should also seek advice if you have symptoms that might suggest an underlying health condition such as diabetes or heart disease.
Can stress, anxiety or depression cause ED?
Yes. Mental health plays a big role in sexual function. Stress, low mood and anxiety can reduce arousal and interrupt the body’s normal response. Men often still get morning erections but struggle during sex, which can suggest emotional rather than physical causes.
Can lifestyle changes improve ED?
Lifestyle changes such as regular exercise, reducing alcohol, stopping smoking, improving sleep and losing weight can help improve ED. These changes support better blood flow, energy and mood, and often make tablet treatments work more effectively.
Is ED permanent or can it go away?
ED is often temporary and can improve once the cause is treated. If ED is due to stress, tiredness or lifestyle habits, changes can help erections return. If it is related to a medical condition, treatment of that condition often improves symptoms.
Can ED medicines interact with other medicines?
Yes, some medicines can interact with ED tablets, including nitrates for chest pain or certain blood pressure medicines. This can cause unsafe drops in blood pressure. Your clinician checks all your medicines to recommend the safest treatment.
Does pornography affect ED?
Pornography doesn’t cause ED directly, but excessive use can affect arousal and create unrealistic expectations, which might contribute to performance anxiety. Reducing usage and focusing on real intimacy can help if it is affecting confidence.
What tests might I need for ED?
A clinician may check your blood pressure, blood sugar, cholesterol and hormone levels to identify any underlying causes. These tests help guide personalised treatment and ensure any medical issues are treated properly.
Are there myths about ED that aren’t true?
Yes. Tight underwear, masturbation or cycling rarely cause ED. Most erectile issues have medical, lifestyle or emotional explanations. If something worries you, it’s better to discuss it with a clinician rather than rely on myths or assumptions.
Is ED more common in men with diabetes or heart disease?
Yes. Diabetes and heart disease can reduce blood flow or damage nerves, which are both essential for erections. Treating these conditions often helps ED improve, and tablets may work better once health issues are controlled
