Researchers at Johns Hopkins University last year looked at 3,400 healthy Americans and found that men who were vitamin D deficient were 32% more likely to have trouble getting it up than those with sufficient levels, even after adjusting for other ED risk factors. In fact, the connection is so common, Walker says D levels are something he always checks in ED patients. Why? The sunshine vitamin is crucial for keeping the endothelial cells that line blood vessels healthy. Without enough of the stuff, blood flow is inhibited, affecting everything from your heart to your hard-on.

A study published in the journal Fertility and Sterility that analyzed the effect of various fruit and vegetables on sperm quality discovered carrots had the best all-round results on sperm count and motility — a term used to describe the ability of sperm to swim towards an egg. Men who ate the most carrots saw improved sperm performance by 6.5 to 8 percent. The Harvard researchers attribute the boost to carotenoids, powerful antioxidative compounds in carrots that help the body make vitamin A.
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.
Peanuts contain a trove the amino acid L-arginine, which is one of the building blocks of nitric oxide, which aids your efforts under the covers. They also help reduce cholesterol levels. The less cholesterol you have in your system, the easier it is for blood to circulate throughout your body and down, which can help you maintain a firmer erection longer.
"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."
In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction. 
He might have been introduced to it by some of his pals (if that is so you might need to make him understand that some of his friends are a bad influence and stop befriending these kids). 7. PIED ( porn induced erectile dysfunction- it is a new condition that most men who were watching porn for some time get it sooner or later, some REALY scary stuff for a man!). Your son sounds like a decent kid who is crying for help.
There have been some studies to suggest that a placebo effect that improves ED may work for some men. One study found that men taking an oral placebo pill showed as much improvement in ED symptoms as men who took actual medication to improve ED. Conversely, men who were given therapeutic suggestions to improve ED did not see signs of symptom improvement.
Aggressive and excessive sexual behaviour is most common cause of ED. Males practicing self-stimulation, coition, or gaining erections without ejaculation few times in a day suffer with problems like ED due to exhausted reproductive system. Tufan herbal ED pills provide natural erectile dysfunction treatment by handling effects of these practices as well. These are regarded as the best ED pills as these not only protect a male from ill-effects of these issues but also reverse their effects to improve health and energy levels of male reproductive system.
Feeling fatigued, very stressed, depressed or dealing with another mood-related issue that can lower libido. Sources of stress and diminished quality of life — such as “deteriorating economic position,” unhappiness with one’s job or other aspects that lower emotional health — are believed to be major causes for sexual dysfunction in both men and women
These “sea pistachios,” as Kimmy Schmidt called them, are no joke.They’re one of the richest food sources of erection-enhancing Vitamin B12 you can find. The boner-boosting bivalves are also high in L-arginine, an amino acid that converts to nitric oxide (NO), the Marvin Gaye of naturally occurring gases: It causes blood vessels to relax and facilitate blood flow, helping you get and stay hard. Additionally, clams are high in muscle-building protein.
The article discusses erectile dysfunction (ED) with the special emphasis on epidemiology, as well as the currently available medical treatments. Describing treatment methods authors paid special attention to natural therapies (as Panax ginseng, Tribulus terrestris, Vaccinium macrocarpon), because taking into consideration their safety profile, they appear to be an important alternative to therapies with synthetic molecules. From substances of natural origin, extract from the fruit of Tribulus terrestris ranks itself high on in collation at the end. The results of most clinical trials and experiments clearly demonstrate its effectiveness in improving sexual function in men.

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
Consider this:  penicillin, the first successful antibiotic, was derived from molds that inhibit bacterial growth.  Scientists had to figure out why the molds slowed bacteria, and refine the active ingredients.  Using herbal supplements is somewhat like putting mold on a wound.  It might help, a little, but it’s certainly not going to help as much as using penicillin.

How common is impotence? According to findings from several studies, including “The Massachusetts Male Aging Study,” overall prevalence for men between 40–70 years old is around 52 percent (or around 30 percent of all men between 18–60 years old). That’s right — nearly half of all men over 40 experience erectile dysfunction symptoms at some point. Not surprisingly, research demonstrates that impotence is increasingly prevalent with age. Around 40 percent of men in their 40s experience sexual dysfunction. Up to 70 percent of men in their 70s experience ED. (1) Every year more than 617,000 new cases of impotence occur in the United States alone.


Tribulus terrestris is a dicotyledonous herbal plant of the Zygophyllaceae family, used to increase serum testosterone levels, which has only been shown in animal studies (40). A prospective, randomized, double blind study of 30 men showed that Tribulus terrestris was not more effective than placebo on improving IIEF scores or serum total testosterone (41). Two accounts of hepato-nephrotoxicity have been reported in young men who ingested high doses of this herbal medication (42,43).
Poor sleep patterns can be a contributing factor for erectile dysfunction, Mucher says. One review published in the journal Brain Research emphasized the intricate relationship between the level of sex hormones like testosterone, sexual function, and sleep, noting that testosterone levels increase with improved sleep, and lower levels are associated with sexual dysfunction. Hormone secretion is controlled by the body’s internal clock, and sleep patterns likely help the body determine when to release certain hormones.
