The oyster has always had an aphrodisiac reputation. One reason may be that oysters have high levels of the mineral zinc, which plays an important role in the production of the male hormone testosterone, and low levels of testosterone could be one reason for erectile dysfunction. Research presented at an American Chemical Society meeting may offer another connection: Raw shellfish contain compounds that stimulate the release of sexual hormones in both men and women.
According to Daneshgari, "Your best bet is to eat a healthy diet that is good for your heart and your circulation." Other foods that are good for your circulation include cranberries, apples, peanuts, onions, tea, and red wine. Chances are, if you take good care of your vascular health, you will avoid many of the common causes of erectile dysfunction.
Qigong is a form of breathing exercises commonly practised in Asia to maintain health (53). In a cross-sectional population-based comparison study in Taiwan, individuals practising Qigong demonstrate higher SF-36 scores in the domains of physical functioning, role limitations due to physical problems, bodily pain, general health and vitality (54). Techniques to concentrate the energy or qi in the pelvis or genitals are regularly practised, but the effects of Qigong on ED have not been studied.

In TCM, the meridian system is thought to represent a path through which the life energy qi flows and as discussed in earlier section, the “Jing” (kidney) qi plays an important role in penile erection. Acupuncture helps to correct the imbalances to relieve physical symptoms by stimulating various meridian points. The Shensu (BL23), Zusanli (ST36) and Neiguan (PC6) points represents important acupoints for penis stimulation and thus has a positive homeostatic effect on the autonomic nervous system, and potentially modulate NO release (55,56). While some studies have showed up to a third of patients reported improvement in penile erection and sexual activity, systematic review showed insufficient data to conclude that acupuncture is an effective intervention for treating ED (56,57). Therefore, further scientific research is required to investigate whether there are specific benefits of acupuncture for men with ED before acupuncture can be accepted as evidence-based practice.
According to the FDA (Food and Drug Administration), many of these products sold on the internet contain potentially harmful compounds. And they aren’t listed on the label. In an investigation, the FDA found that one-third of these online supplements were laced with undisclosed ingredients. This includes sildenafil—the active ingredient in Viagra. Doctors prescribe Viagra to some patients, but it’s not safe for everyone. The drug could interact with other medications and lower your blood pressure to dangerous levels. This makes ordering supplements online risky. You don’t know whether they contain sildenafil or other ingredients that could harm your health.
