Three mechanisms trigger these vascular changes: psychogenic, reflexogenic and centrally originated (nocturnal erections). Psychogenic erections occur through stimulatory pathways (e.g., sound, smell, sight and touch) that travel from the spinal erection centres (T11–L2 and S2–S4) and induce a dopaminergic initiation of erection from the medial pre-optic area.17 Reflexogenic erections, induced by direct genital stimulation, send ascending messages to the central erection centres and direct messages to the autonomic nuclei, which explains residual erectile activity in patients with upper spinal cord injuries. Nocturnal erections, initiated in the pontine reticular formation and amygdalae, are seen during REM sleep and are believed to be caused by a relative decrease in sympathetic inhibition with augmentation of the pro-erectile centres.

Trauma to the pelvic region or spinal cord can damage veins and nerves needed for erection. Surgery of the colon, prostate, bladder, or rectum may damage the nerves and blood vessels involved in erection. Prostate and bladder cancer surgery often require removing tissue and nerves surrounding a tumor, which increases the risk for impotence.
The most significant improvements over placebo are at dosages of 4mg to 6mg. However it was clear in this same trial and others (9, 15, 16, 18), that increased dosages also increase the likelihood of the most common side effect of nausea. These side effects are reported to diminish with continued dosing. (15)

Erectile Dysfunction: Psychological Causes
Whether the cause is physiological or psychological, homeopathic remedies can help resolve the problem of erectile dysfunction. According to the Law of Similars at the core of homeopathic medicine, “like cures like”—that is, small amounts of a substance that would cause a symptom will also cure that symptom in a patient. The natural substances, usually derived from a plant or herb, are diluted many times so that they are nearly harmless. Homeopaths believe that this dilution makes them a very potent remedy.

Formal neurological testing is not needed in the vast majority of patients with ED. Those with a history of CNS problems, peripheral neuropathy, diabetes, or penile sensory deficit would probably benefit from some level of neurological testing. The sensitivity of the skin of the penis to detect vibrational stimuli, ie, biothesiometry, can be used as a simple nerve function office screening test. This involves the use of a small electromagnetic test probe placed on the right and left sides of the shaft and on the glans. The vibrational amplitude is adjusted until the subjective sensory threshold is reached, which is determined by questioning the patient. A series of these tests determines the average vibrational sensory threshold in each location, which are then compared to reference range standards for the patient's age group. Although this test does not directly measure the erectile nerves, it serves as a reasonable screening for possible sensory deficit and is simple to perform. Formal nerve conduction studies, such as bulbocavernosus reflex latency time, are reserved for very select situations.

A. Penile implant surgery is usually a last resort. Although there is nothing wrong with this approach, for many men it's a disservice. In medicine, the option of last resort is usually something that rarely works or has terrible side effects. Implants present a medical conundrum because they are one of the best treatments we have for ED. Implants have the highest patient and partner satisfaction rating, running higher than 90 percent. The only reason they're offered last is because of the surgery involved. In addition, if removal of the device is necessary, the other erectile dysfunction treatments will not be effective because corporal tissue is destroyed with implantation. Also, its risks, although very infrequent, can be significant.

Most insurance policies, including Medicare, cover at least part of the costs of a vacuum constriction device, especially if a medical cause for ED has been documented. Medicaid, however, does not cover the device.
One variation of the vacuum device involves a semirigid rubber sheath that is placed on the penis and remains there after erection is attained and during intercourse.
