Getting frequent exercise and maintaining a healthy weight are, of course, also important. Plus, avoiding or minimizing risky dietary factors such as salt, alcohol, caffeine, and too much animal products is crucial. Animal protein elevates insulin-like growth factor 1 (IGF-1) in the blood, a growth-promoting hormone that is associated with increased risk of several cancers and cardiovascular disease.19, 20
Most cases of sexual dysfunction are related to a physical cause. The most common causes are diabetes, heart disease, neurological trauma or disease, and side effects of medications. Stress and anxiety can also contribute to impotence. While most of the focus has been on men with erectile dysfunction, a number of women also suffer from this disorder.

The bad news: Men with diabetes are three times more likely to report having problems with sex than non-diabetic men. The most common sexual problem is Erectile Dysfunction, or ED, sometimes called impotence. Even worse, because ED is such a private issue, many men feel embarrassed to discuss the problem with their doctor, or even their partner, so the problem is never addressed.
Few simple laboratory tests can help identify obvious causes of organic ED. Initial labs should include HbA1c, free testosterone, thyroid function tests, and prolactin levels. However, patients who do not respond to pharmacological therapy or who may be candidates for surgical treatment may require more in-depth testing, including nocturnal penile tumescence testing, duplex Doppler imaging, somatosensory evoked potentials, or pudendal artery angiography.
Some research even suggests the effect of blood pressure drugs may be more psychological than physical. When ED occurs after a man begins to take a new medication, it's possible that anxiety about his health, rather than the medication, may trigger the problem. And being aware of possible side effects may make a man more likely to recognize them as abnormal.
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.
Another risk factor is that men with type 2 diabetes may produce less than normal amounts of testosterone, a condition called hypogonadism. A 2007 study found that one-third of men with type 2 diabetes had low testosterone levels. Those men were also more likely to have ED, though the link may have to do with weight, not diabetes per se. Being overweight or obese is a risk factor for hypogonadism.
Pomegranate juice. Drinking antioxidant-rich pomegranate juice has been shown to have numerous health benefits, including a reduced risk for heart disease and high blood pressure. Does pomegranate juice also protect against ED? No proof exists, but results of a study published in 2007 were promising. The authors of this small-scale pilot study called for additional research, saying that larger-scale studies might prove pomegranate juice's effectiveness against erectile dysfunction. "I tell my patients to drink it," says Espinosa. "It could help ED, and even if it doesn't, it has other health benefits."
Yet another common erectile dysfunction treatment that can be used in combination with oral drugs is a vacuum pump. This device consists of a plastic cylinder, a pump, a set of constriction bands, and a water-soluble lubricant. The lubricant is applied to the base of the penis to help form an airtight seal. The cylinder is placed over the flaccid penis and held tight against the pelvis. The pump is used to create a vacuum within the cylinder, drawing blood into the penis. Once the penis is engorged with blood, a constriction band is rolled off the cylinder to near the base of the penis. The constriction band is helpful for men with venous leakage, in which blood flows out of the penis as fast as it flows in. However, it should be left on for no more than 30 minutes at a time.
