A new study in the International Journal of Men’s Health shows 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 vector. Other studies have previously observed that circumcision’s damage results in worsened erectile functioning, inability to maintain an erection, and reducing the glans sensitivity, including an overall penis sensitivity reduction by 75%. A recent study discovered that premature ejaculation is five times more likely when adjusted for erectile dysfunction and circumcision.
Moreover, in Israel- a country that routinely circumcises their baby boys for religious reasons- Viagra is so common there that the Pfizer pharmaceutical company asked for permission to market Viagra without a doctor's prescription- making it an over-the-counter medication.
The truth is, you simply cannot change form without altering function. While there are immediate dangers and harm caused by circumcision, there are also other problems that may not arise until much later in life. One of these dangers is erectile dysfunction (more commonly known as ED).
One of the major reasons that circumcision can lead to ED is because of keratinization. The glans (or head) of the penis is intended to be an internal organ, protected by the prepuce (foreskin). When the foreskin is removed, the head is completely exposed to the elements, including a constant rubbing against clothing. Over time, the skin thickens to protect the glans (much like a callous forms in areas of excessive friction). The head becomes dry and thick and is no longer supple and moist.
As men grow older, the thickened skin of the glans becomes less and less sensitive, which can cause men to have issues with erections. Sensitivity loss is also contributed to the circumcision itself, which removes the majority of the specialized nerve endings in the penis (over 20,000).
