Male circumcision is the surgical removal of the foreskin.
The foreskin is the retractable fold of skin that covers the end of the penis. It's a continuation of the skin that covers the whole penis.
This page focuses on circumcision for non medical reasons.
Circumcision is a common practice in the Jewish and Islamic communities, and it's also practised by many African communities.
Most non-medical circumcisions are carried out on children.
