“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.

“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.

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,”
