Medicine is the branch of health science and the sector of public life concerned with maintaining or restoring human health through the study, diagnosis, treatment and possible prevention of disease and injury. It is both an area of knowledge – a science of body systems, their diseases and treatment – and the applied practice of that knowledge.
Duplex ultrasound is used to evaluate blood flow, venous leak, signs of atherosclerosis, and scarring or calcification of erectile tissue. The man's comfort level is also frequently a factor, especially in maintaining an erection. It is estimated that over 70% of all serious impotence cases are the result of diabetes, kidney diseases, multiple sclerosis, endocrine disorders, vascular diseases, and high blood pressure, as well as neurological diseases. One of the most underestimated causes of impotence is cigarette smoking — as if you need yet another reason to quit. A physician measures the latency between squeeze and contraction by observing the anal sphincter or by feeling it with a gloved finger inserted past the anus.

Penile erection is managed by two mechanisms: the reflex erection, which is achieved by directly touching the penile shaft, and the psychogenic erection, which is achieved by erotic or emotional stimuli. The former uses the peripheral nerves and the lower parts of the spinal cord, whereas the latter uses the limbic system of the brain. In fact, almost 100% of men who use cocaine regularly are impotent. These involuntary erections mean that everything is fine with the nerves, muscles and arteries involved in the erection process, and signals that the cause of impotence is elsewhere. A physician measures the latency between squeeze and contraction by observing the anal sphincter or by feeling it with a gloved finger inserted past the anus. If you suspect this may be the cause, you can perform a simple test to see if impotence is just in your mind. A significant proportion of men who have no sexual dysfunction nonetheless do not have regular nocturnal erections. One of the most promising herbs is the purified extract of Tribulus terrestris. Although they are often dismissed as ineffective solutions to impotence, more and more clinical research studies have found that herbs can help impotent men. One of the most underestimated causes of impotence is cigarette smoking — as if you need yet another reason to quit. It is estimated to affect between 10 million and 15 million men in the United States alone.
