The variations in severity of erectile dysfunction make estimating its frequency difficult. Many men also are reluctant to discuss erectile dysfunction with their doctors due to embarrassment, and thus the condition is underdiagnosed. Nevertheless, experts have estimated that erectile dysfunction affects 30 million men in the United States. In prescribing sildenafil, a doctor considers the age, general health status, and other medication(s) the patient is taking. The usual starting dose for most men is 50 mg, however, the doctor may increase or decrease the dose depending on side effects and effectiveness. The maximum recommended dose is 100 mg every 24 hours, however, many men will need 100 mg of sildenafil for optimal effectiveness, and some doctors are recommending 100 mg as the starting dose. What are vacuum devices? Mechanical vacuum devices cause an erection by creating a vacuum around the penis that draws blood into the penis, engorging it, and expanding it. One variation of the vacuum device involves a semi-rigid rubber sheath that is placed on the penis and remains there after attaining erection and during intercourse. online pharmacy cialis arizona cialis online What are intracavernosal injections? Medications can be injected directly into the corpora cavernosa to attain and maintain erections. Medications such as papaverine hydrochloride, phentolamine, and prostaglandin E1 (alprostadil) can be used alone or in combinations to attain erections. Combining small amounts of each drug is preferred over using a single drug because of increased efficacy and fewer side effects. Even though such injections can be effective in the management of erectile dysfunction (success rate of around 80%), they are not widely used because of their potential complications. These injections are painful, can cause scarring of the penis, and have a higher risk of developing priapism. Other blood tests: Evaluation for hemochromatosis, lupus, scleroderma, zinc deficiency, sickle cell anemia, cancers (leukemia, colon cancer) are some of the other potential tests that may be performed based on each individual's history and symptoms. cialis viagra online buy viagra Direct vibrational stimulation (biothesiometry) is occasionally done to evaluate penile nerve function. Small electromagnetic electrodes are placed on the shaft of the penis and vibration amplitude is slightly adjusted until sensation is noted by the patient. Although this test does not measure the exact nerve function, it serves as a screening method to detect any sensory nerve deficit as the cause of ED.
