Our new study published in the International Journal of Men’s Health showed that circumcised men have a 4.5 times greater chance of suffering from erectile dysfunction (ED) than intact men, revealing what appears to be a significant acquisition factor. Robert S. Van Howe, M.D., M.S., FAAP and I found a surprisingly strong secondary finding between circumcision and ED in our survey of 300 participants (OR = 4.53, p=.0058). It was outside the scope of our article to delve deeper into this topic, but our finding does raise some questions: Are there other studies showing a similar connection? What could be the underlying cause?
