DHEA. DHEA, or dehydroepiandrosterone, is a natural hormone that the body uses to make the male hormone testosterone. DHEA and testosterone decrease with age, just as ED increases with age, so it seems that taking DHEA might protect against ED. But Harris says that "it is unlikely that taking DHEA would raise your testosterone enough to make much difference." DHEA should not be used by people with liver problems; it also has many side effects.
The definition of erectile dysfunction (ED) is the inability to obtain or maintain an erection firm enough for sexual intercourse. Historically, admitting to having ED was considered taboo and downright embarrassing until the advent of sildenafil citrate (Viagra) in 1998. Sildenafil liberated men from the stigma of having ED, and it opened a conversation about a problem that has existed for centuries. Up to 10% of men younger than forty suffer from ED and upwards of 60% by age 69.1
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.
Some scholarly minds believe it wasn’t an apple, but a pomegranate with which Eve tempted Adam in the Garden of Eden. She was smart: A recent study published in the International Journal of Impotence Research discovered that pomegranate juice, rich in antioxidants that support blood flow, can help improve erectile dysfunction. Though this study was funded by POM Wonderful, animal studies have also shown that the elixir improves long-term erectile response, so it’s definitely worth a shot–literally. Knock a shot back or water your juice down a bit: One cup of tart POM Wonderful packs 31 grams of sugar.
Ginkgo biloba. Known primarily as a treatment for cognitive decline, ginkgo has also been used to treat erectile dysfunction -- especially cases caused by the use of certain antidepressant medications. But the evidence isn't very convincing. One 1998 study published in the Journal of Sex & Marital Therapy found that it did work. But a more rigorous study, published in Human Pharmacology in 2002, failed to replicate this finding. "Ginkgo has come out of fashion in the past few years," says Ronald Tamler, MD, assistant professor of medicine and codirector of the men's health program at Mount Sinai Medical Center in New York City. "That's because it doesn't do much. I can say that in my practice, I have not seen ginkgo work -- ever."
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.
Most importantly, herbal supplements are not well regulated in the United States.  Studies have shown that 40-50% of herbal supplements do not even contain the supposed main ingredient, and many contain substances that are not listed which may have dangerous side effects2.  Another study found that over two thirds of the products tested had substituted other plant species for the plants listed on the label, and a third of products also contained other fillers or contaminants3.  A study by the New York State Attorney General of herbal products sold at GNC, Target, Walgreens, and Walmart found that four out of every five products didn’t contain the ingredient they claimed!  Fourteen US states and territories have petitioned Congress to regulate the herbal supplements industry.
Some of the herbs used in these herbal ED pills are aphrodisiacs which enhance testosterone secretion in male body. This hormone rejuvenates exhausted reproductive system, stimulates nerve functions and improves strength and endurance of other organs of male genital region. Optimum availability of testosterone hormone removes all sorts of debilities which may occur in male reproductive system due to reasons of ED or due to ageing and diseases. Higher testosterone level promoted by these herbal ED pills promote higher sensation in male genital region to cause intense arousals, active nerves promoted by these best ED pills stimulate sensation and also delay a male’s ejaculation for longer period. All these benefits provide natural erectile dysfunction treatment by causing intense arousals and promote powerful erections.
The Aztecs referred to avocados as testicles because of their scrotum-like appearance. They were onto something.

Plus, avocados’ good monounsaturated fats protect your heart and boost circulation, while their abundant minerals and carotenoids supply energy and stamina. For some creative ways to consume the fruit, check out our 10 avocado recipes for weight loss.
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.
