While these side effects mainly create discomfort, some individuals are at risk for more serious, even life-threatening reactions to these drugs. Some men have reported fainting after taking impotence medications, and priapism (a painful condition involving an erection that does not subside after more than four hours) has also occurred as an effect of impotence drugs. This condition can lead to permanent nerve damage; injectable drugs may also cause irreversible damage to the penis if used incorrectly.
Besides mammalian organs, insects and arthropods are also consumed as aphrodisiacs in Eastern medicine. These include scorpions, spiders, beetles, flies and other bugs (32). Penile erections can be observed following administration of neurotoxins as it causes repetitive firing of the somatic, sympathetic and parasympathetic neurons, resulting in autonomic and neuromuscular over-excitation. Scorpions are often used as an ingredient found in herbal wines. However, there is a general lack of literature regarding the consumption of scorpion neurotoxins for potency.
Encouraging evidence suggests that ginseng may be an effective herbal treatment for ED. However, further, larger, and high-quality studies are required before firm conclusions can be drawn. Promising (although very preliminary) results have also been generated for some herbal formulations. Overall, more research in the field, adhering to the CONSORT statement extension for reporting trials, is justified before the use of herbal products in ED can be recommended.
Erectile dysfunction (ED) is the inability to achieve or maintain an erection sufficient for intercourse. Because ED can have a strong psychological component, counseling with a psychotherapist or sex therapist often works. However, more often ED is a symptom of cardiovascular disease and diabetes, both of which can impair blood supply to the penis. In addition, many medications interfere with sexual functioning.
In a prospective human phase 1 open-label and single-arm study reported by Haahr et al. (27), 17 men with refractory post radical prostatectomy ED were given a single intracavernosal injection of autologous adipose-derived regenerative cells (ADRCs) freshly isolated after a liposuction. The procedures were well-tolerated and over a 6-month follow-up period, 8 of 17 men showed improvement of their erectile function.
The most common adverse events associated with all of the PDE-5 inhibitors10 are headaches in 16% of men; flushing in 10% of men; dyspepsia (7%); nasal congestion (4%), and visual disturbances/color sensitivity in about 3%. Tadalafil distinguishes itself from vardenafil and sildenafil by the relative lack of visual side effects. It does, however, have an additional possible adverse effect, which is back pain and/or myalgia.11
Admit it or not, when it comes to our sex life, we all want it exciting, sometimes wild and most of all, something that lasts longer. Unfortunately, stress and everyday chores have impacted our sexual desires the most, causing various issues, one of which is erectile dysfunction. And believe it, men cannot go soft when it is about satisfying your partner!
While the rationale behind why it would work is airtight, the research on arginine’s actual effect on erectile dysfunction is slim, points out Charles Walker, M.D., assistant professor of urology and cofounder of the Cardiovascular and Sexual Health clinic at Yale University. But given its solid safety profile, minimal side effects, and potential benefit on heart disease, it’s worth a try, he adds, especially when taken in conjunction with other herbs on this list, which studies have shown can be more effective.
The B vitamin folic acid is good for cardiovascular health. Keeping your blood flowing smoothly is a key to preventing and even treating erectile dysfunction (ED). After all, ED is often an early warning sign of heart problems. In particular, some men have high levels of homocysteine, which can contribute to heart problems. Findings show that eating foods high in folate and taking folic acid supplements may help lower high homocysteine levels. Lots of foods contain folic acid, including spinach, tomatoes, and orange juice. But most of us don’t get enough of these heart healthy foods in our daily diet. To boost folic acid, look for a supplement with about 525 milligrams (mg) of this vitamin. That’s good advice for everyone, and might help with your ED. Research suggests that for some men with ED and high homocysteine levels, taking folic acid may be a key to helping ED medications like Viagra perform well.
Men looking to boost their sperm quality should head to the fish counter, research suggests. Sperm size and shape — one marker used to evaluate male infertility — was better in men who ate the most white meat fish as compared to men who ate the least, a study published in The Journal of Nutrition showed. And total sperm count was about 34 percent higher among men who ate the most dark meat fish, like salmon and tuna, than men who ate the least amount of fish. Meanwhile, men who reported eating one to three servings of processed meat had worse sperm morphology (shape) than men who ate the fewest servings.

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. 
Following the breakthrough in ED treatment using PDE5-inhibitors, Western medicine has now moved on to a new frontier of regenerative medicine, with stem cell and gene therapy leading the way (25). There is a practical need for novel therapy as a significant portion of diabetic or post-prostatectomy ED patients do not respond to oral pharmacotherapy. To date, stem cells derived from different sites including adipose tissue-derived stem cells, bone marrow mesenchymal stem cells and muscle-derived stem cells have been investigated using animal models for ED, to study their effects on neural, vascular, endothelial or smooth muscle regeneration (25,26).
A number of nonprescription products claim to be herbal forms of Viagra. Some of these products contain unknown amounts of ingredients similar to those in prescription medications, which can cause dangerous side effects. Some actually contain the real drug, which should be given by prescription only. Although the Food and Drug Administration has banned many of these products, some potentially dangerous erectile dysfunction remedies remain on the market.
