Vascular diseases affect blood vessels. They restrict blood flow to organs such as the heart, brain, and kidneys. In erectile dysfunction, vascular diseases restrict blood flow to the penis. Vascular diseases may be responsible for causing ED in as many as 50% to 70% of men who develop the condition.
Restriction of blood flow caused by a vascular disease is usually caused by a buildup of cholesterol and other substances that may block blood vessels. In some men, the blood vessels in the penis, and the rest of the body, may not function properly. They may restrict blood flow when they're not supposed to. The good news is that lifestyle measures and drug treatments typically work for types of vascular disease that can cause erectile dysfunction.
Like the stock market and foreign-car engines, erections are mysterious things that seem to have a mind of their own. When they don’t happen, it can be hard (so to speak) to figure out why. But these answers should help.
Your penis must store blood to keep an erection. If the veins in the penis cannot prevent blood from leaving the penis during an erection, you'll lose your erection. This is called venous leak. Venous leakage may occur with vascular disease. Venous leakage is also associated with diabetes, Peyronie's disease (buildup of scar tissue in the penis that leads to curved, painful erections), certain nerve conditions, and even severe anxiety.
