IntroductionCircumcision is the surgical removal of the foreskin from the human penis. Male circumcision is one of the first surgical procedures performed for approximately four thousand years. Approximately eighty percent of the world's male population is uncircumcised and only the remaining twenty percent is circumcised. Among the remaining 20% ​​of the male population, circumcision is performed primarily for religious reasons in Jewish and Islamic cultures. Therefore, male circumcision is widely practiced nationwide only in the Muslim world – parts of Asia and Africa – and in most cases in Israel. The high rate of circumcision performed for non-religious reasons prevails in only a few non-Islamic and non-Jewish cultures. In North America, particularly the United States, the male circumcision rate reached 80-90% between the 1970s and 1990s. According to the CDC (Centers for Disease Control and Prevention), the national rate of neonatal circumcision in the United States dropped dramatically in the 2000s; the latest national survey conducted by the National Hospital Discharge Survey (NHDS) shows an average male circumcision rate of less than 50% among US men in the 2000s, with a low of 31.4% in 2003. Non-religious male circumcision is rarely practiced in Asia; non-neonatal circumcision is only observed in South Korea and the Philippines: more specifically, the Philippines has a long history of circumcision tradition dating back to the arrival of the Spanish in the 16th century. Despite the fact that Koreans historically and religiously did not perform male circumcision prior to the 1945 or 1950 Korean War, South Korea is the only country where a high rate of male circumcision is performed nationwide to this day and cultural. The comparison between three different… half of the article… Whether religious, medical or mandatory factors have little influence on circumcision in Korea, since 60% responded that the reason for circumcision was due to social customs and personal -consciousness, 80% of decision making was made by children, and most Koreans had no information about circumcision: social and cultural reason seems to be the most influential factor for nationwide widespread circumcision in South Korea .Moreover, the study of Korean parents, regardless of gender and age, have a uniform or common perception regarding circumcision. Careful observation of the prevalence of circumcision in South Korea leads to the conclusion that Koreans, both children and parents, are strongly influenced by social psychology when making a decision about circumcision. Therefore, social pressure is the main cause of circumcision rather than any specific religious or medical reason.
