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. The former uses the peripheral nerves and the lower parts of the spinal cord, whereas the latter uses the limbic system of the brain. It is estimated that about 10% to 20% of impotence cases are the direct result of various psychological factors, such as low self-esteem, depression, and — especially — stress and anxiety (general and performance anxieties). 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. The vacuum forces blood into the penis, which in turn causes an erection.
Although they are often dismissed as ineffective solutions to impotence, more and more clinical research studies have found that herbs can help impotent men.

Be sure to select a Tribulus extract that contains at least 45% protodioscin..
Injecting prostaglandin, a hormone-like stimulator produced in the body, induces erection. Now it is also defined as the inability to maintain an erection or ejaculate. The effect that Brindley discovered established the fundamentals for the later development of specific, safe, orally effective drug therapies. It works as follows: The cylinder is placed on the penis and the pump is then used to draw air out of the cylinder. Impotence, or erectile dysfunction, was once regarded as a man's worst nightmare. Several types of FDA approved vacuum therapy devices are available with a doctor's prescription. A vacuum device composed of a plastic cylinder, pump and elastic ring or band can be used to affect an erection. Although middle-aged and older men are more likely to be impotent than younger men, impotence can strike at any adult age. 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.
