VASCULAR Buy Super Fildena Online of the arteries carrying blood to the penis is the most common cause of physical (as opposed to psychological) erectile dysfunction. It can be caused by diabetes or by all the same factors that increase the risk of heart attack—anything that tends to cause blockages in the blood vessels that lead to the heart will do the same in the blood vessels leading to the penis. Smoking, excessive alcohol consumption, a sedentary lifestyle, and a diet high in cholesterol and saturated fat, or low in “good” high-density lipoprotein (HDL) cholesterol, all contribute to atherosclerosis (hardening of the arteries). In Buy Super kamagra Online , the resulting erectile dysfunction can be symptomatic of a much more serious problem. A responsible health care practitioner will not simply prescribe Viagra in such cases, which might produce an erection, despite the impeded blood supply, but would do nothing to remedy the possibly life-threatening blockage of the arteries around the heart. A healthy, low-fat diet, regular exercise, quitting smoking, and moderate drinking will usually bring about the return of natural erections, as well as increased life expectancy.

In rare cases, there may be a block in the blood supply to the penis not connected to atherosclerosis. Generally this is the result of damage to the pelvis. In Buy Cenforce-D 120mg Online , revascularization surgery can be performed to bypass the blockage by transferring a blood vessel from beneath the abdominal muscle and connecting it to the penile artery. This procedure is usually reserved for younger men who do not show signs of atherosclerosis. In rare cases where a specific arterial lesion is suspected, arteriography (a radiological procedure in which x-ray-sensitive “dye” is introduced introduced into the arteries) can be considered with a view toward reconstructive surgery.

Hypertension (high blood pressure) is another common vascular cause of erectile dysfunction. Here, it is not buildup of cholesterol in the walls of the arteries that is the problem, but simply constriction of the blood vessels, though the result is the same—less blood is able to move through the system.

One cause of vascular ED that until recently was little known is bicycling. While the cardiovascular benefits of serious cycling are a big health benefit, it seems that the tremendous pressure concentrated on the penile artery by those pointy bicycle seats can cause ED in those men who log serious miles on their bikes each year. This phenomenon has been an unspoken secret in the competitive cycling world and only came to light in the last year or so, despite the fact that some doctors estimate that more than 100,000 American men have been left permanently impotent from cycling. New bicycle seats that spread pressure to other areas of the pelvis are now on the market, and it is my hope that all concerned cyclists will try them out.

If an individual is able to achieve erection normally, but then quickly loses it, we know that the problem is not with the arteries but rather that other half of the circulatory system—the veins. As we all recall from our first biology class the veins return the oxygen-depleted blood to the heart. As we discussed previously, for an erection to occur blood must reach the penis and be trapped there, and this trapping is accomplished by the swelling corpora cavernosa pinching off the veins against the tunica albuginea. In a venous leakage disorder, this pinching off is not completely successful, and blood slips out of the penis and back into the general blood supply, causing the erection to “deflate” just like a leaking tire. Doppler ultra sonography (color flow doppler ultrasound) can help to reveal blood flow through the penis and determine if this is the problem. This form of vascular ED is much rarer than the arterial form.
