What Is Erectile Dysfunction?

Erectile dysfunction (ED) is the inability to get or maintain an erection firm enough for satisfactory sexual activity. Occasional difficulty is normal and doesn't necessarily mean you have ED.

ED is considered a problem when it:

ED and Heart Disease: An Important Link

The blood vessels in the penis are smaller than those in the heart. This means they can be affected by cardiovascular disease before symptoms appear elsewhere.

ED can be an early warning sign of heart disease. Studies show that men with ED are more likely to have a heart attack or stroke in the following years.

If you have ED, especially if you're over 40, your GP should assess your cardiovascular risk factors.

Causes of Erectile Dysfunction

ED usually has physical causes, but psychological factors are also common.

Physical Causes

  • Cardiovascular disease
  • Diabetes
  • High blood pressure
  • High cholesterol
  • Obesity
  • Low testosterone
  • Prostate problems/treatment
  • Neurological conditions
  • Medications (see below)
  • Smoking
  • Alcohol excess

Psychological Causes

  • Stress and anxiety
  • Depression
  • Relationship problems
  • Performance anxiety
  • Past sexual trauma
  • Low self-esteem

Medications That Can Cause ED

Never stop prescribed medications without talking to your doctor — there may be alternatives.

Treatment Options

Lifestyle Changes

These can significantly improve ED and your overall health:

Medications (PDE5 Inhibitors)

Sildenafil (Viagra)

Take 30-60 mins before sex. Lasts 4-6 hours. Available over the counter.

Tadalafil (Cialis)

Can last up to 36 hours. Can be taken daily at low dose.

Vardenafil (Levitra)

Similar to sildenafil. Take 25-60 mins before.

Avanafil (Spedra)

Works faster — can work in 15 mins.

These medications work by improving blood flow to the penis. They need sexual stimulation to work.

Important Safety Warning

Do NOT take PDE5 inhibitors if you use nitrates (GTN spray, isosorbide mononitrate). The combination can cause a dangerous drop in blood pressure.

  • Tell your GP about all medications you take
  • Avoid if you've had a recent heart attack or stroke
  • Use with caution if you have low blood pressure

Other Treatments

Seeing Your GP

Many men feel embarrassed talking about ED, but GPs deal with this issue regularly. It's an important health matter to discuss.

What to Expect

Questions to Ask

  • What's likely causing my ED?
  • Should I have tests for heart disease or diabetes?
  • Could any of my medications be contributing?
  • What treatment options would suit me?
  • Are ED medications safe for me to use?

Buying ED Medications

Sildenafil (Viagra Connect) is now available without prescription from pharmacies. However:

If you're over 40 or have risk factors for heart disease, see your GP first. ED can be an important warning sign that shouldn't be ignored.

Avoid Buying Online from Unregulated Sources

Fake medications are common online. They may:

  • Contain no active ingredient
  • Contain dangerous substances
  • Be the wrong dose

Only buy from UK-registered pharmacies or get a prescription from your GP.

Relationships and Communication

ED can affect both partners. Open communication is important:
