Circumcision is a surgical procedure that involves removing the foreskin of the penis, either partially or completely.
The practice is more common in some areas of the world than others. According to the World Health Organization, circumcision is most common in North Africa, West Africa, and the Middle East. In these areas, more than 80% of men and boys are circumcised. Malaysia, the Philippines, and South Korea also have high circumcision rates.
In Australia and North America, circumcision rates fall between 20% and 80%.
In most of Asia, Europe, Central America, and South America, circumcision is less common, with prevalence rates below 20%.
Rates may vary within different countries among various ethnic groups.
