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).
To achieve and maintain an erection, healthy blood vessels and an optimum blood flow are essential. Significantly, therefore, Dr. Rath’s research has proven that specific micronutrients play key roles in maintaining the structural integrity of blood vessels and optimizing blood flow. Such micronutrients include vitamins C and E, the amino acids lysine and proline, and the mineral copper.
A study published in May 2014 in The Journal of Sexual Medicine found that some men can reverse erectile dysfunction with healthy lifestyle changes, such as exercise, weight loss, a varied diet, and good sleep. The Australian researchers also showed that even if erectile dysfunction medication is required, it's likely to be more effective if you implement these healthy lifestyle changes.
