Diabetes mellitus
Diabetes and erectile dysfunction can occur concurrently in the majority of older males. In fact, the likelihood of developing erectile dysfunction is 50% higher in men with diabetes. The reason for this is because diabetes affects the body’s glucose metabolism. The overabundance of glucose in the bloodstream can cause nerve and blood vessel injury. Damage to the blood vessels and nerves surrounding the penis and testicles may impede the ability to attain or sustain an erection.
