Erectile dysfunction affects most men at some point in their lives. Recent data has shown that more than half of all British men between 40 and 70 have some degree of ED. It may only happen once, or it may be a regular issue. It can be a part of ageing, though it can happen at any age. While ED can be embarrassing, it's common and treatable.

“ED is very common. By 2025, the condition is expected to affect approximately 322 million men worldwide – a figure that has more than doubled since 1995.” – Dr Neel Patel

ED and impotence can have physical, lifestyle, medicinal and psychological causes. Most often, it is due to a reduced blood flow to the penis. We’ve compiled the most common below:

“ED can have both physical and psychological causes. In most cases it is due to a reduced blood flow to the penis. However external factors, including some lifestyle choices, can also cause erectile problems.” - Dr Neel Patel

Losing or failing to maintain an erection can be a one-off event. However, if you have had multiple erection problems it is best practice to see your GP or visit a sexual health clinic.

At your appointment, you may:

• Be asked about your medical history, sexual history and mental health factors
• Take basic health / cardiovascular checks, i.e. measuring blood pressure and heart rate
• Undergo a physical examination of your penis, or a digital rectal examination if you show signs of an enlarged prostate

We ask similar questions as a part of our online erectile dysfunction service (see above), if you'd rather not answer these questions face-to-face.

ED can often be a symptom of a health condition affecting your blood vessels and heart. These can include high blood pressure, diabetes or high cholesterol. If left untreated these could lead to serious health problems such as heart or kidney disease. We advise you to have a health check to check there is no underlying condition causing your ED.

“As erectile dysfunction has many possible underlying causes, there are multiple different ways to treat it. It’s important to establish what is causing the issue with your doctor so the correct course of treatment can be advised.” - Dr Neel Patel

8 out of 10 men will have a good chance of ED medication working. It increases blood flow to the penis, enabling an erection when aroused.  

Having erectile dysfunction does not directly affect fertility. However, it can understandably make conceiving difficult.

The following can impact male fertility:

There are several ED treatments available in both pill and cream forms. If you’re wondering which erectile dysfunction treatment is best for you, take a look at this comparison table.

Several of these treatments are available in their generic forms (Sildenafil, Tadalafil, etc.). Take an online consultation to determine which treatment is right for you.

Previous studies have shown that long-term use of tadalafil (the active ingredient in Cialis) and alprosdatil (the active ingredient in Vitaros cream) is safe. The NHS has also stated that sildenafil (the active ingredient in Viagra) is safe for long-term use.

If your erectile dysfunction persists after treatment talk to your GP.

If you don’t feel that medical treatment for erectile dysfunction or impotence is right for you, there are several alternative treatments available:

• Counselling can help if stress or anxiety are causing your ED.
• Lifestyle changes like a healthier diet or cutting back on alcohol or drug use can have a positive effect on blood flow.
• Devices like vacuum pumps or constriction rings can also be effective.
• Penile prosthesis surgery can be performed. However, this is a last resort option to patients that have failed to respond to any medical, mechanical or psychological treatment.
• Non-prescription remedies and pills for sale online are often not regulated. For your safety, we advise you to avoid these.
