Taking one of these tablets will not automatically produce an erection. Sexual stimulation is needed first to cause the release of nitric oxide from your penile nerves. These medications amplify that signal, allowing some men to function normally. Oral erectile dysfunction medications are not aphrodisiacs, will not cause excitement and are not needed in men who get normal erections.
To correct ED, Cellular Medicine takes a different approach to that of conventional medicine. In the absence of psychological causes, the primary cause of ED is cellular dysfunction as a result of micronutrient deficiency. In this respect, ED is essentially no different to any chronic disease. To successfully resolve the problem, it is necessary to resupply the body’s cells with optimum levels of micronutrients.
The development of PDE5-inhibitors is a clear example of how Western medicine approached the problem of ED differently from Eastern medicine. The erectogenic effect of sildenafil (Viagra®) was discovered by accident when patients undergoing heart clinical trials reported better erections as a side effect after taking sildenafil. This observation led to further elucidation of the NO/cGMP signalling pathway and development of PDE5-inhibitors as a first-line therapy in ED (5).
