During sexual stimulation, sexual thoughts, or nocturnal erections, the neurotransmitter nitric oxide (NO) is released from the endothelial cells and the parasympathetic nerve terminal causing relaxation of two cylinder-like muscles called the corpora carvenosum. Nitric oxide influences an increase in concentrations of cyclic guanosine monophosphate (cGMP), which after numerous pathways triggers smooth muscle relaxation, and simultaneous closing of small veins traps blood in the cavernosal muscles, keeping blood in the cavernosal tissues that cause and maintain an erection.
Studies show that just 30 minutes of walking each day can be beneficial to those fighting ED. One Harvard study linked 30 minutes of walking per day with a 41 percent drop in the risk of erectile dysfunction. Some research shows that moderate exercise can help restore sexual performance in men who are middle-aged, obese, and have been diagnosed with ED.
Erectile dysfunction can occur as a side effect of medication taken for another health condition. Common culprits are high blood pressure meds, antidepressants, some diuretics, beta-blockers, heart medication, cholesterol meds, antipsychotic drugs, hormone drugs, corticosteroids, chemotherapy, and medication for male pattern baldness, among others.
6. Have you suffered from testicular atrophy? 7. Have you suffered from erectile dysfunction? 8. Do you experience pain in your penis? 9. If so, describe the pain. 10. Is there any one incident which you feel might have acted as the trigger for this condition? 11. Has the rate of shrinkage increased or decreased over the years? 12. Do you drink? 13. Do you notice any worsening of symptoms as a result of drinking? 14. Do you smoke? 15.
Researchers discovered men who regularly consumed flavanoid-rich foods—especially those with anthocyanins, flavones, and flavanones—experienced a significantly reduced risk of the disorder than those who did not. Good news since the foods are already popular in American diets. Lead researcher Aedin Cassidy says, “…the top sources of anthocyanins, flavones and flavanones consumed in the U.S. are strawberries, blueberries, red wine, apples, pears and citrus products.”
The fowl most associated with belt-loosening feasts is lean, high in protein and the single best food source of arginine, the amino acid. Researchers at the NYU School of Medicine gave L-arginine to a group of impotent men, and found that six out of 15 men receiving the amino acid claimed an improved ability to achieve erections, while none of the 15 men in the placebo group reported any benefit. Additionally, the bird is rich in DHA omega-3 acids, which have been shown to boost brain function, improve your mood and turn off fat genes, actually preventing fat cells from growing! Just make sure you buy white meat only, as dark contains too much fat. And steer clear of prepackaged, sliced lunchmeat—those turkeys are strictly jive.
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.
