Erectile dysfunction (impotence) is very common, particularly in men over 40. It's usually nothing to worry about, but see a GP if it keeps happening.

What is erectile dysfunction?

Erectile dysfunction is when you are either:

• unable to get an erection
• unable to keep an erection for long enough to have sex

Depending on the cause, you may still be able to get an erection at other times, such as when you wake up. Sometimes you might also have low sex drive (loss of libido).

Causes of erectile dysfunction

Most men occasionally fail to get or keep an erection. This is usually caused by stress, tiredness or drinking too much alcohol, and it's nothing to worry about. It can also be a side effect of some medicines. If erectile dysfunction happens often, it may be caused by a condition such as:

• high blood pressure or high cholesterol
• diabetes
• depression or anxiety
• hormone problems

Things you can do to help with erectile dysfunction

Healthy lifestyle changes can sometimes help with erectile dysfunction.

Do

• lose weight if you're overweight
• stop smoking
• eat a healthy diet
• exercise daily
• try to reduce stress and anxiety

Don’t

• do not drink more than 14 units of alcohol a week
• do not cycle for a while, if you cycle for more than 3 hours a week

How sexual health clinics can help with erection problems

Sexual health clinics treat problems with sexual health. They can provide the same treatment you would get at your GP surgery. Many sexual health clinics offer a walk-in service, where you do not need an appointment. They'll often get test results quicker than GP practices. Find a sexual health clinic near you.

What happens at your appointment

If you see someone about erectile dysfunction, the doctor or nurse may:

• ask about your lifestyle and relationships, and any problems you might be having
• do some basic health checks, such as taking your blood pressure
• examine your genitals to rule out any obvious physical cause

If you have symptoms like needing to pee more often than usual, you may also have an examination of your prostate (rectal examination).

Treatments for erectile dysfunction

Treatment can usually help improve erectile dysfunction. The main treatments are medicines that increase the blood flow to your penis, called PDE-5 inhibitors. These include:

• sildenafil (Viagra)
• tadalafil (Cialis)
• vardenafil (Levitra)
• avanafil (Spedra)

You can get sildenafil on prescription or you can buy it from a pharmacy. You need a prescription for the other types.

Treating the cause of erectile dysfunction

There are also treatments for some of the causes of erectile dysfunction. For example:

• your doctor may switch you to a different medicine if it's causing your erectile dysfunction
• high blood pressure, high cholesterol and hormone problems may be treated with medicine
• counselling and therapy can help if your erection problems are linked to emotional or mental health problems – but there can be a long wait for these services on the NHS
