Pudendal nerve lesions in young men with erectile dysfunction:imaging with 3T magnetic resonance neurography

Dear Editor,Erectile dysfunction(ED)is a major health problem worldwide that reduces the quality of life of many families.ED is recognized as a consistent or recurrent inability to achieve and/or maintain a penile erection sufficient for sexual satisfaction.Epidemiological data have shown that ED is associated with increasing age.?Nevertheless,the prevalence of ED is increasing in younger men(<40 years of age),with previous estimates as high as 30%.More recent studies have also reported organic causes in 5%-72%of ED patients<40 years old,and suggested involvement of the pudendal nerve(PN)as primary cause.3.4 The aim of this study was to evaluate the clinical utility of magnetic resonance neurography(MRN)for visualizing and quantifying PN changes in young men with ED.
