=== Physical effects ===

* [[Circumcision scar]] is an invariable effect.

* An unavoidable effect of any circumcision is the permanent loss of sexual sensitivity. This is partly due to the removal of sensory tissue. The [[foreskin]] contains very many nerve endings and touch receptors, which account for the major part of male sexual sensation. If the [[foreskin]] is removed, they can no longer provide sexual stimulation. It is also partly due to the fact that the surface of the [[Glans penis|glans]] reacts to the missing protection from friction and drying out by developing a callus layer. This reduces the sensitivity of the remaining nerves in the [[Glans penis|glans]] gradually over the years. The study conducted by Sorrells et al.<ref>{{Sorrells etal 2007}}</ref> found a significant reduction of sensitivity to touch for [[circumcised]] compared to [[intact]] [[penis]]es in adult males. Other studies revealed that [[circumcised]] men use condoms significantly less often than [[intact]] men, since they further limit the sexual sensitivity (see above).
