Can Diabetes Cause Permanent Erectile Dysfunction?

Diabetes can cause lasting nerve and blood-vessel damage that contributes to erectile dysfunction, but ED is not inevitable and can often be improved or treated. ED is common among men with diabetes, and the risk may increase over time as high blood sugar damages the nerves and blood vessels essential for erections. Some people with type 2 diabetes already have ED when diabetes is diagnosed, partly because type 2 diabetes can go unrecognized for years. Managing blood sugar, addressing other cardiovascular risk factors, and using appropriate ED treatments may help prevent worsening and improve erectile function for many people. Early intervention with diabetes management, exercise, and ED treatments like medications or devices offers the best outcomes for preserving sexual health.
