In the field of pharmacology, potency is a measure of drug activity expressed in terms of the amount required to produce an effect of given intensity. As can be understood from the mechanisms of a normal erection, impotence may develop due to hormonal deficiency, disorders of the neural system, lack of adequate penile blood supply or psychological problems. Restriction of blood flow can arise from impaired endothelial function due to the usual causes associated with coronary artery disease, but can also be caused by prolonged exposure to bright light. Once an erection is achieved, the man places the elastic ring on the base of his penis, which keeps blood from draining from the penis back into the body. Prescribed drugs used to treat high blood pressure, ulcers, depression, and prostate cancer, as well as medications to prevent baldness or aid in dieting, can have side effects that include impotence. 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.
