These drugs facilitate erection by inhibiting the PDE5 enzyme, by blocking the degradation of cyclic guanosine monophosphate (cGMP) in the cavernous smooth muscles. This inhibition results in the prolonged activity of cGMP, which further decreases intracellular calcium concentrations, maintains smooth muscle relaxation and, hence, results in rigid penile erections.
The herb is particularly effective for those whose willy woes are based on other medications: An older study from the University of California found ginkgo biloba is 76% effective in treating sexual dysfunction caused by antidepressants. “Gingko helps counteract sexual dysfunction caused by certain antidepressants called SSRIs by blocking serotonin activity in the erectile centers of the brain, ultimately leading to better synthesis and bioavailability of nitric oxide,” Walker explains.
Classic dietary staples, like the chicken breast, may not have the Instagram presence of say, maca, but they earn a place on plates much longer. Simply put, their health benefits continue to stack up. In addition to a hefty amount of arginine — only turkey has more — a 3-ounce cooked chicken breast contains only 142 calories and 3 grams of fat, but an impressive 26 grams of protein. That’s more than half of the day’s recommended allowance. Plus, it’s rich in B vitamins to rev your metabolism and energy levels. (And if you’re looking to treat erectile dysfunction, those B vitamins definitely don’t hurt.)
The same device is considered a vacuum erectile device (VED), when it is used to increase inflow of the blood to the penis without a constriction band. Regular use of VED in post-prostatectomy patient increases penile oxygenation and is accepted as a valid option in penile rehabilitation. Recent study reported transient increase in oxygenation to the glans penis and corporal bodies were detected by oximetry after VED was applied, providing proof for possible role for VED to counter the early penile hypoxia, cavernosal fibrosis and long-term ED after radical prostatectomy (9).
The search for a cure for erectile dysfunction (ED) dates back way before the introduction of Viagra in the 1990s. Natural aphrodisiacs, from ground rhinoceros horn topa chocolate, have long been used to increase libido, potency, or sexual pleasure. These natural remedies are also popular because they’re said to have fewer side effects than prescribed medications.
Another age-old therapy for ED is acupuncture. This is an ancient Chinese treatment where thin needles are inserted into specific points of the body to relieve all kinds of illnesses. Acupuncture has been used to treat ED for years. Studies show that acupuncture improves erection as well as in the treatment of erectile dysfunction with psychological cause.18
Ginkgo Biloba is promoted to treat conditions ranging from hypertension to Alzheimer’s dementia. There is evidence that shows improvement of memory enhancements in the geriatric population (47), improvement in terms of cognitive function via effect on cerebral vasculature (48), improvement of claudication distance and cutaneous ulcers in patients with peripheral vascular disease (49). Ginkgo Biloba extract is proposed to induce NO in endothelial cells and thus causing relaxation of vascular smooth muscles. Animal studies have reported relaxation of rabbit corpus cavernosal smooth muscle cells with the use of Ginkgo Biloba (50). Adverse effects include headaches, major bleeding (in patient who are taking warfarin concurrently) and seizures with reported fatality (36).
Sometimes low libido or sexual dysfunction can occur due to low testosterone levels. But that doesn’t necessarily mean you need a testosterone supplement. Your body usually can produce adequate testosterone, but it needs downtime to convert precursor hormones into testosterone. If you’re burning the candle at both ends, your body will convert those precursors into cortisol instead. So rest, relax, and allow your body to build up its testosterone stores.
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.
In this study, 78 patients aged 25 to 50 suffering from mild to moderate erectile dysfunction were given this supplement. This study lasted 12 weeks and the size and duration of the erection was the focus of the study. At the conclusion of the study, it was determined that this supplement made a significant difference compared to the controls on parameters like sexual desire, intercourse satisfaction, orgasmic function and overall satisfaction. Side effects were mild and similar to those observed in the control group. Once the trail finished, 90 percent of those taking the VXP supplement wished to continue taking the product because of the impact they observed. 
lung issues, neuropathy, arthritis, vision problems, thyroid dysfunction, erectile dysfunction etc. etc. are all due to depression. I think you are dead wrong! ALL of these are documented potential side effects of interferon, in the literature. Its just that the literature does not indicate that the problems might persist long term in a significant group of patients. How are you so certain that the interferon has nothing to do with these problems again????
