Your circumcision might be affecting your erection, according to a new study published in the International Journal of Men’s Health. For the study, researchers surveyed 300 men and found those who were circumcised had a 4.5 times greater chance of suffering from ED compare to their non-circumcised counterparts.

According to a study published in the British Journal of Urology International, it might have to do with the fact that circumcised penises can experience up to a 75% reduction in sensitivity.

The major factor that contributes to this loss of sensitivity is the severing of the perineal nerve, which happens to be located on the underside of the penis that is responsible for the majority of sexual sensory input.

Of course, there are numerous other factors that also contribute to ED: aging, diabetes, obesity, cigarette smoking, and poor diet. What's important is to bring up your concerns about ED during your next doctor’s visit, as it is so much more common than most men realize, yet can be easily fixed by making a few lifestyle adjustments or getting on a medication.
