Key takeaways

ED affects a large share of men over 40 and becomes more common with age.
It is often an early warning sign of heart or vascular disease — worth investigating, not ignoring.
Most men respond to tablets; injections and a vacuum device are the next steps.
A penile implant is considered when those have failed — and satisfies most men who choose it.

Erectile dysfunction (ED) is the persistent difficulty getting or keeping an erection firm enough for sex. It is very common — and very treatable. It is also worth taking seriously, because it can be an early sign of a wider health problem.

What causes it

Most ED is physical rather than psychological. The common causes are vascular (narrowed blood vessels, the same process behind heart disease), diabetes, nerve damage, hormonal changes, and the side effects of some medicines. Because the arteries in the penis are small, ED often shows up years before a heart problem does — which is why a new, unexplained case deserves a check-up, not just a prescription.

The treatments that work

Treatment follows a ladder. First come lifestyle changes and tablets such as sildenafil or tadalafil, which help most men. If tablets are not enough, the next steps are injections that produce an erection directly, or a vacuum device. Each works well for some men and not others.

Erectile dysfunction is a marker of overall health as much as a condition in its own right — treating it well means looking at the whole man, not just the symptom. — AUA guidance

When surgery helps

When tablets, injections and a vacuum device have all failed or are not tolerated, a penile implant becomes the sensible next step. It is the most reliable option of all, works on demand, and satisfies the great majority of men who choose it. We cover the operation in detail in our guide to penile implant surgery.

The important thing is that ED is almost always treatable at some level. If the first thing you try does not work, that is information, not a dead end — there is a clear path from tablets through to surgery, and a good andrologist will walk you along it.

Common questions

Is erectile dysfunction curable?

It is highly treatable, and sometimes reversible when the cause is addressed (for example, changing a medication or improving diabetes control). Where it is not reversible, treatments from tablets to implants restore function reliably.

Does ED mean I have heart problems?

Not necessarily, but it can be an early warning sign of vascular disease. A new, unexplained case is worth discussing with a doctor, who may check your blood pressure, cholesterol and blood sugar.

At what age does ED usually start?

It becomes more common with age and affects a large share of men over 40, but it can occur at any age and is not an inevitable part of getting older.
