Evidence status: EstablishedDiabetes and Erectile Dysfunction
Can diabetes cause erectile dysfunction?
Yes. Diabetic erectile dysfunction is common: diabetes can damage blood vessels and nerves and often coexists with high blood pressure and cholesterol, all of which can affect erections. ED may also be an early sign of poorly controlled diabetes. Managing blood sugar and cardiovascular risk matters alongside any ED treatment.
Key fact: Diabetes can damage blood vessels and nerves and is a well-established risk factor for erectile dysfunction. (European Association of Urology, 2026; page updated )

How diabetes affects erections
- Long-term high blood sugar can damage small blood vessels and reduce endothelial function.
- Neuropathy can interfere with sexual sensation and nerve signalling.
- Diabetes often coexists with high blood pressure, high cholesterol, obesity and heart disease.
- Low testosterone, depression and medicines can also contribute.
Diabetic erectile dysfunction: assessment and treatment options
The doctor reviews blood sugar control, cardiovascular risk, medicines and hormones where indicated. PDE5 tablets are commonly first-line. Vacuum devices, injections and other therapies may be used when tablets are unsuitable or insufficient. Shockwave therapy may be considered in selected men with a blood-flow pattern.

It can help protect blood vessels and nerves, but it cannot be promised to restore erections.
