Erectile dysfunction, heart disease and other vascular diseases: The root cause of the narrowing of the arteries is caused by atheroma. Atheroma is like fatty patches or plaques that develop within the inside lining of arteries. (This is similar to water pipes that get furred up with scale.) Plaques of atheroma may gradually form over a number of years in one or more places in the body, commonly in arteries going to the heart, brain, legs and penis. In time, these can become bigger and cause enough narrowing of one or more of the arteries to cause symptoms and problems. buy levitra without prescription Liver enzymes and liver function tests: Advanced liver disease (cirrhosis) can result in hormonal imbalance and gonad dysfunction leading to low testosterone levels. Thus, evaluation for liver disease may be necessary in cases of erectile dysfunction. viagra online without prescription overnight buy viagra
How is erectile dysfunction treated? ED is primarily treated by tackling the cause of the problem, whether this is physical or psychological. The narrowing of the arteries (called atherosclerosis) is one of the most common causes of ED. In these cases your GP may suggest lifestyle changes, such as losing weight, to try to reduce your risk of cardiovascular disease. This may help to relieve your symptoms as well as improving your general health. You may also be given medication to treat atherosclerosis, such as cholesterol-lowering statins and drugs to reduce your blood pressure. buy levitra without prescription In randomized controlled trials, an estimated 60% of men with diabetes, and 80% of men without diabetes experienced improved erections with sildenafil.

In some cases, treatment can involve prostaglandin tablets in the urethra, injections into the penis, a penile prosthesis, a penis pump or vascular reconstructive surgery. buy levitra without prescription Melanocortin receptor agonists are a new set of medications being developed in the field of erectile dysfunction.
