Abundant blood dilates the arterioles in the erectile tissues and ensures better erection. In women, good blood flow also ensures sexuality. It is assumed that the person is not suffering from depression.
Erection Failure – How to Restore Sexual Capacity
By Conrado D. Fontanilla
Steps toward erection
The first step: arousal. Second step: the corpus cavernosum, a spongy erectile tissue, releases nitric oxide a messenger molecule. Third step: nitric oxide nudges the formation of cyclic guanosine monophosphate (cGMP). Fourth step: cGMP relaxes blood vessels and allows filling in of blood in erectile tissues. Fifth step: erection.
How to maintain erection
Why does erection fail? The enzyme phosphodiesterase-5 (PDE-5), also present in the corpus cavernosum, breaks down cGMP and inhibits blood flow to sex organ. A good flow of blood that dilates the arterioles in the erectile tissues ensures better erection (Walbroehl, G. M.D. Sexuality in the Handicapped. American Family Physician, July 1987).
How to maintain erection? The enzyme PDE-5 must be inhibited in doing its work. Sildenafil (Viagra) inhibits PDE-5 so that the level of cGMP remains high and corpus cavernosum fills with blood resulting in longer erection (Encyclopedia Britannica 2008).
A person taking blood pressure medication or nitroglycerin should not take Viagra because these can send him into shock (Lauersen, N., M.D. and E. Stukane. 2000. Listen to Your Body). This might be due to overdose of nitric oxide that drastically reduces blood pressure. Nitroglycerin also supplies nitric oxide which was earlier on called endothelium-derived relaxation factor (Encyclopedia Britannica 2008).
Anti-hypertensive drugs can cause infertility, thus lessen sexual capacity (Ornish, D. M.D. 1995. Dr. Dean Ornish’s Program for Reversing Heart Disease). Beta blockers (Propranolol) can reduce libido.
Erection failure may be due to leriche syndrome that is due to the narrowing of the lowest portion of the aorta where it branches out into two arteries: one supplying blood to the right half of the body, the other to the left side. Impotence is a secondary symptom of this occlusion (Walker, M. M.P.D. 1984. The Miracle Healing Power of Chelation Therapy, pages 44-46).
Free radicals injure arteries that develop atherosclerosis resulting in lessened blood flow.
Beuford Masterson, a tobacco farmer of Kingston, Tennessee was afflicted with leriche syndrome in the 1980s. Erectile difficulty was gone by taking oral and intravenous chelation therapy, according to Walker. Natural oral chelators are the antioxidant vitamins A, C, and E.
Antioxidants sweep up free radicals and counteract atherosclerosis.
Anti-clotting agents and magnesium promote the flow of blood, and revitalize organs.
Reduces stress or depression with natural tranquilizers from vegetables and fruits, like noni.
Coenzyme Q10 is essential in the conversion of glucose into energy.
Melatonin, a hormone from the pineal gland, protects the prostate gland cells from free radicals.
B-3 (niacin) helps in the synthesis of sex hormones. B-1 (thiamin) and B-3 enhance blood formation and circulation (Pedersen, S. 2000. Vitamin B: Balancing Body and Mind).
B-5 (pantothenic acid) builds up stamina and cures depression.
Noni juice promotes the production of nitric oxide, a messenger that triggers relaxation of smooth muscles, dilation of arteries (Elkins, R. The Noni Revolution) and allows the filling in of blood in the corpus cavernosum resulting in erection.
