Possible causes - Physical

Erection problems (EPs) usually have an underlying physical cause. It’s useful to bear this in mind for patients with co-morbidities that may predispose them to EPs. Many physical conditions and diseases can cause erection problems. These may include:

Heart disease

The most common physical cause of EPs relates to the health of the heart and blood vessels. 

Cardiovascular disease can lead to the build-up of fatty deposits in the blood vessels of the penis. It is then more difficult to achieve or sustain an erection as blood is less able to flow to the penis.

In some cases, erection problems can be a warning sign of cardiovascular disease.

High blood pressure

Hypertension damages the lining of blood vessels, including those in the penis. Which can have a lasting effect on erections as blood is restricted, and blood vessels fail to open up adequately to allow sufficient blood flow into the penis.

High Cholesterol

This can clog up the blood vessels and prevent enough blood flow to the penis for an erection.


Diabetic men are at a high risk of developing erection problems as the high blood glucose levels may damage blood vessels and nerves, including those in the penis.


Men who are overweight have a higher chance of developing heart disease, as well as other conditions which can affect blood flow to the penis.
