It is normal for a man to have five to six erections during sleep, especially during rapid eye movement (REM). In both conditions, an intact neural system is required for a successful and complete erection. Additionally, adequate levels of testosterone (produced by the testes) and an intact pituitary gland are required for the development of a healthy erectile system. More drastically, inflatable or rigid penile implants may be fitted surgically. As testosterone and other male sex hormone levels start to drop after reaching middle age, low testosterone level is often the culprit in most intermittent impotence problems, especially in older men. Although they are often dismissed as ineffective solutions to impotence, more and more clinical research studies have found that herbs can help impotent men. 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. Boredom, marital problems or negative feelings toward your partner may contribute to an impotence problem. Their absence may indicate a problem with nerve function or blood supply in the penis. Some of the most popular herbs available on the market today are Tribulus, yohimbe, ginkgo biloba, and others.

These pumps should be distinguished from other penis pumps (supplied without compression rings) which, rather than being used for temporary treatment of impotence, are claimed to increase penis length if used frequently, or vibrate as an aid to masturbation. These studies showed that Tribulus helps treat impotence caused by low testosterone levels or an imbalance in the body's level of sex hormones. Stimulation of the penile shaft by the nervous system leads to the secretion of nitric oxide (NO), which causes the relaxation of smooth muscles of corpora cavernosa (the main erectile tissue of penis), and subsequently penile erection. Impotence, or erectile dysfunction, was once regarded as a man's worst nightmare.-Mr.Robinson, Ohio
