What Is Erectile Dysfunction? Also known as impotence, erectile dysfunction is defined as the inability to attain and/or maintain an erection suitable for intercourse. Causes of erectile dysfunction include diseases affecting blood flow, such as atherosclerosis (hardening of the arteries); nerve disorders; psychological factors, such as stress, depression, and performance anxiety (nervousness over his ability to sexually perform); and injury to the penis. Chronic illness, certain drugs, and a condition called Peyronie's disease (scar tissue in the penis) also can cause erectile dysfunction. Vacuum devices - There are several different devices. Basically, you put your penis into a plastic container. A pump then sucks out the air from the container to create a vacuum. This causes blood to be drawn into the penis and cause an erection. When erect, a rubber band is placed at the base of the penis to maintain the erection. The plastic container is then taken off the penis and the penis remains erect until the rubber band is removed (which must be removed within 30 minutes). Lifestyle: smoking is a key cause of erectile dysfunction. Smoking causes impotence because it promotes arterial narrowing. See also Tobacco and health. How Is Erectile Dysfunction Treated? There are many different ways erectile dysfunction can be treated, including oral medications, sex therapy, penile injections, suppositories, vacuum pumps, and surgery. Each type of treatment has its own advantages and disadvantages. Talk to your doctor to determine the best treatment for you. The search for an erectile dysfunction panacea has been on for years, with other researchers targeting nitric oxide as well.

Erectile dysfunction (ED) means that you cannot get and/or maintain an erection. In some cases the penis becomes partly erect, but not hard enough to have sex properly. In some cases, there is no swelling or fullness of the penis at all. ED is sometimes called impotence. Prostaglandin E1 injection test is sometimes performed to determine the penile blood flow. Prostaglandin is directly injected into the corpora cavernosa in order to cause dilation of blood vessels and promote blood flow into the penis. If erection ensues, it confirms normal or adequate blood flow to the penis. This can also provide information about possible therapeutic options. Free viagra samples
