Impotence, or erectile dysfunction (ED), is the inability for a man to sustain an erection long enough for normal, satisfying sexual intercourse. To understand the underlying causes of impotence, it helps to know the basics about how an erection develops, along with potential problems that get in the way. Erections begin in the brain with a thought related to sexual desire. Then a chemical message travels from the brain to the penis. Blood flow to the penis increases as blood vessels leading to the reproductive system relax and allow for increased circulation.
A guy has a heart attack at 45 because he took treatment. doesn't mean the treatment caused it. could have been his genetics and a million gut bombs..or that he was a prison subject, still it will go down in the list of possible side effevts. there's no way to prove a drug causes evert reaction. Not when they are only around for a few years anyway.Part of the bad rap for GH comes from all the misuse, athletic and hollywood, but docs won't prescribe megadoses for people to become the hulk.
Arginine. The amino acid L-arginine, which occurs naturally in food, boosts the body's production of nitric oxide, a compound that facilitates erections by dilating blood vessels in the penis. Studies examining L-arginine's effectiveness against impotence have yielded mixed results. A 1999 trial published in the online journal BJU International found that high doses of L-arginine can help improve sexual function, but only in men with abnormal nitric oxide metabolism, such as that associated with cardiovascular disease. In another study, published in 2003 in the Journal of Sex & Marital Therapy, Bulgarian scientists reported that ED sufferers who took L-arginine along with the pine extract pycnogenol saw major improvements in sexual function with no side effects. Arginine can be helpful, says Geo Espinosa, ND, director of the Integrative Urological Center at NYU Langone Medical Center. Espinosa says that men with known cardiovascular problems should take it only with a doctor's supervision; L-arginine can interact with some medications.
"This is the first study to look at the association between flavonoids and erectile dysfunction, which affects up to half of all middle-aged and older men," said lead researcher, Professor Aedin Cassidy. "Men who regularly consumed foods high in these flavonoids were less likely to suffer erectile dysfunction. In terms of quantities, we're talking just a few portions a week."
While Western medicine emphases the link between cardiovascular function and ED, TCM places importance on liver and kidney ailments as causative factor for development of ED. Western medicine involves a step-wise approach by targeting the relevant organ systems to treat various clinical symptoms; but TCM focuses on restoring the balance between various organs to achieve harmony and holistic approach to inner sense (4). The following article reviews our current understanding regarding the philosophical approach, and evaluates the evidence surrounding various ED therapies between mainstream Western medicine and TCM (see Table 1).
If you like your food like you like your lovers—sweet and spicy—you’re in luck. Ginger is another food that can improve your bedroom life by aiding blood flow and improving artery health. According to a study in the International Journal of Cardiology, consuming a mere teaspoon of the stuff a few times a week is all you need to reap the heart-healthy benefits. The spice has also been shown to boost levels of testosterone and sperm viability. So go ahead and place that second order of sushi this week—just don’t leave the ginger on your plate.
When considering vitamin supplementation for erectile dysfunction, one of the first vitamins that you may come across in literature would be Vitamin D. This is a vitamin that can be easily obtained through many types of dairy products like milk, cheese, and yogurt and is also in abundance if you live in a tropical climate. Sunlight is able to give us a natural dose of vitamin D daily.  Although vitamin D is usually associated with improving bone strength and prevention osteoporosis, another valuable feat of vitamin D is the fact that it helps reduce atherosclerosis. Studies confirm that there is a similar underlying mechanism that occurs between conditions like cardiovascular disease and erectile dysfunction. As blood vessels are damaged and filled with plaques, the diameter for blood to flow through is gradually reduced. After a few years, the amount of blood may be reduced substantially. Vitamin D is able to help activate cells that remove some of these dangerous plaques and delay the onset of ED.
