Quien és mas macho? A recent study by French researchers found that men who eat the most spicy foods tend to have higher testosterone levels than those with milder palates. Study authors attribute the T-boosting effects in part to capsaicin, a compound in chilies that previous research has associated with increased testosterone levels. Seriously spicy serrano peppers are also packed with quercetin, a nutrient shown to boost testosterone levels in the body by reducing the amount that’s otherwise flushed out by the kidneys. Capsaicin, the compound that makes tabasco sauce hot, releases chemicals that increase heart rate, mirror signs of arousal and rev up things.
Ginseng. Korean red ginseng has long been used to stimulate male sexual function, but few studies have tried systematically to confirm its benefits. In one 2002 study involving 45 men with significant ED, the herb helped alleviate symptoms of erectile dysfunction and brought "enhanced penile tip rigidity." Experts aren't sure how ginseng might work, though it's thought to promote nitric oxide synthesis. "I would recommend ginseng [for men with ED]," says Espinosa. Discuss with your doctor before taking it since ginseng can interact with drugs you may already be taking and cause allergic reactions.
"Just because there is evidence doesn't mean it's good evidence," says Andrew McCullough, MD, associate professor of clinical urology at New York University Langone Medical Center in New York City, and one of the original clinical investigators for the ED drug Viagra (sildenafil). "And before men with ED start down the naturopathic route, it's smart to make sure that there isn't some underlying medical condition that needs to be corrected." Moreover, it is estimated that 30 million American men have erectile dysfunction, and 70% of cases are a result of a potentially deadly condition like atherosclerosis, kidney disease, vascular disease, neurological disease, or diabetes. Additionally, ED can also be caused by certain medications, surgical injury, and psychological problems.
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.
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????
While carrots have always been touted for their benefits for the eyes, studies reveal that carotenoids, vitamins, and minerals present in carrots act as antioxidants, anticarcinogens, and immune enhancers. Carrots also boast of antihypertensive, hepatoprotective, renoprotective, and wound healing benefits as well as cardio- and hepatoprotective, antibacterial, antifungal, anti-inflammatory, and analgesic effects. Studies on male rats have shown that carrots can exert an effect on fertility by elevating testosterone levels in them.10
I lost sensation in the penis after a while and could last for ages in the bedroom as it was desensitized / numb however I stopped getting erections, sorta like erectile dysfunction (this was a problem for 3-4 months even after I stopped), I immediately stopped the extender type traction device, although I have a suspicion i lost feeling as I had the traction on much to high.
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. 
If you’ve been to the health food store lately, you’ve seen shelves lined with vitamins and “organic” supplements, each claiming to boost immunity, revitalize organ function, or “promote health.” And it’s working. Supplements are currently a $30 billion industry in the US, with more than 90,000 products on the market, and vitamin use is on the rise. In fact, a recent survey in Journal of American Medicine Association showed that “52% of US adults reported use of at least 1 supplement product.”
For obvious reasons, ED can be a sensitive subject, one that until relatively recently men were more likely to try to hide than to deal with. Fortunately, a deeper understanding of the variety of causes of erectile dysfunction has led to medications, therapies, and other treatments that can be more individualized and more likely to be effective—and more open discussion about addressing the concern.
Yohimbine: The main component of an African tree bark, yohimbine is probably one of the most problematic of all natural remedies for ED. Some research suggests that yohimbine can improve a type of sexual dysfunction that is linked with a drug used to treat depression. However, studies have linked yohimbine to a number of side effects, which can include anxiety, increased blood pressure, and a fast, irregular heartbeat. Like all natural remedies, yohimbine should only be used after advice and under supervision from a doctor.

Vitamins and minerals are used in systems all over the body. Everywhere from your cardiovascular to your nervous system. It’s a lot to understand. So to help dispel some of the myths and outlandish claims, we’ll take a look at how five common vitamins and nutrients affect one very specific aspect of men’s health—erections. Turns out, vitamins can do more than just ward off the common cold.
