The drug does not directly give a man an erection but it works by boosting the natural mechanism that leads to an erection. When a man is sexually aroused, certain tissues in his penis relax, allowing blood to flow in and fill the penis. Viagra helps by elevating the levels of the chemical that causes the tissues to relax. These effects were discovered accidentally. The drug was originally developed to improve blood supply to the heart in angina sufferers. Duplex ultrasound is used to evaluate blood flow, venous leak, signs of atherosclerosis, and scarring or calcification of erectile tissue. Injecting prostaglandin, a hormone-like stimulator produced in the body, induces erection. Ultrasound is then used to see vascular dilation and measure penile blood pressure. If treating an underlying condition doesn't help your erectile dysfunction, medications or other direct treatments may work. propecia online no prescription A recent study suggests an epidemiological association between chronic periodontitis (periodontal inflammation) and erectile dysfunction, similarly to the association between periodontitis and coronary heart diseases, and cerebrovascular diseases.[17] In all the three conditions (erectile dysfunction, coronary heart disease and cerebrovascular diseases), despite the epidemiological association with periodontitis, no causative connection has proved yet.

A band is worn around the penis for two to three successive nights and it can signal intensity and duration of erections if they occur. If nocturnal erections do not occur, then the cause of erectile dysfunction is likely to be physical rather than psychological, however, tests of nocturnal erections are not completely reliable. Scientists have not standardized the tests and have not determined in whom they should be done.
