Objective:To explore the association between statin therapy and the risk of erectile dysfunction by literature review.Methods:We conducted diversities of search strategies including electronic database searches of MEDLINE,Scopus,Pubmed and Web of Science using MeSH terms,keywords and title words during the search.Reference lists of identified and public articles were reviewed.In addition,only English articles were considered and case reports were not concerned in the review.The key features of recognized applicable search studies were considered and the conclusions were summarized in a narrative review.Results:Different studies gave a consensus that erectile dysfunction was regarded as an early sign of silent cardiovascular disorder and hidden atherosclerosis.Different studies reported that statins might induce erectile dysfunction through induction of peripheral neuropathy,cognitive deficits,and reduction of circulating testosterone.However,most of recent studies illustrated that statins led to a significant improvement in erectile function and sexual health in men with age over forty years.Atorvastatin advanced endothelial nitric oxide concentrations through activation and upregulation of endothelial nitric oxide synthase and rescued phosphodiesterase-5 inhibitors non-responders since nitric oxide and cyclic guanosine monophosphate increased penile blood flow and improved erectile function.Conclusions:According to the assorted view of preponderance,statins improved erectile dysfunction is more dominant than statins induced erectile dysfunction.Therefore,statins regardless of its property improve erectile dysfunction through amelioration of penile endothelial dysfunction,and penile neuronal reflexes that are inter-related during sexual excitation and penile erection.
