The male sexual response can be divided into 3 phases: desire (libido), excitement (arousal) and orgasm. Problems in any of those 3 phases can cause erection problems. Erectile dysfunction (ED), or impotence, is the inability to achieve an erection. Erection occurs when the blood flow to the penis increases when a man becomes sexually aroused. Blood vessels going to the penis dilate, and blood fills the penis causing it to become engorged. This occurs via the secretion of a chemical called nitric oxide (NO). This will typically last until arousal is diminished, or orgasm is achieved. Many conditions can affect erection, especially conditions that can compromise blood flow to the penis. These include physical conditions such as diabetes and vascular disease. Psychological conditions may also have a bearing on the initiation and maintenance of an erection.
Erectile dysfunction, also called impotence (lack of power), is considered to be a typically male problem, because it is generally expected that the penis should become sufficiently hard to enter the vagina and remain there long enough to provide pleasure, orgasm, and ejaculation.
Erectile dysfunction is more prevalent than it may seem. It occurs to some degree in up to 40% of men 40 years old, and up to 67% in those age 70. It is a significant area of research for the pharmaceutical industry, with potential sales in the billions of dollars.
The first aids for ED were mechanical devices: vacuum pumps that draw blood into the penis and implantable balloons or rods. Viagra was the first prescription drug for ED, but it has significant side effects, and should not be used in people with heart disease. It is also exorbitantly expensive. Recently, more attention has been focused on natural and herbal remedies, which seem to be effective yet have fewer side effects.

“For many men, erection difficulties cut to the core of male identity, so these problems can represent a significant loss,” said Barry Reynolds, Ph.D., a University of Southern California psychologist and sex therapist. “Erection difficulties can be equally devastating for the partner not just because of the loss of intercourse, but because of a loss of physical intimacy and emotional closeness.”
“Sexual stimulation and erection begin in the brain where neuronal testosterone-receptor sites are prompted to ignite a cascade of biochemical events that involve testosterone-receptor sites in the nerves, blood vessels, and muscles. Free testosterone promotes sexual desire and then facilitates performance, sensation and the ultimate degree of fulfillment. Without adequate levels of free testosterone, the quality of the male sex life is adversely affected. Studies have found that men with low testosterone routinely suffer from a decreased sex drive, genital atrophy, and impotence. Upon re-establishing youthful levels, subjects commonly report increased feelings of vitality, a higher sex drive, better sexual performance and even penile enlargement and increased genital sensitivity,” explains J. Phillip Vogel, in Le Magazine, May, 2003.
“The erect penis has always been a symbol of power, virility, and fertility. Inability to obtain or maintain an erection, known clinically as erectile dysfunction, is a major health problem. It can cause considerable distress, unhappiness, and relationship problems. The search has therefore continued from time immemorial to find an effective safe, and easy to administer treatment for erectile problems. Although a number of these treatments became available in the last two decades, they all had problems with efficacy, safety, or ease of administration. Clinicians in this field often are told at the end of an assessment interview, “I wish you have a magic pill”. An effective and safe oral treatment is, no doubt, the most acceptable and easy to use option. Finding such a treatment has always been the dream of many scientists, and many attempts have been made over the years. These ranged from herbal remedies used by native healers, mostly in Eastern countries, to the more sophisticated designer drugs, which are based on a better understanding of the physiological mechanism of erection.,” wrote W. R. Guirguis, Sexual Dysfunctions Clinic, St. Clement’s Hospital, Ipswich, England, in the article “Oral treatment of erectile dysfunction: from herbal remedies to designer drugs,”
