This book presents the religious, medical, social and legal debate among Jews, Christians and Muslims around male and female circumcision. If female circumcision today is the subject of a national and international campaign to ban it, male circumcision is accepted and few would dare criticize it. It is estimated wrongly less serious than female circumcision, or with health benefits. The author criticizes this myth maintained by the United Nations and the World Health Organization. He demonstrates that the distinction between male and female circumcision is illusory, both being an unjustifiable flagrant violation of bodily integrity. This distinction is the main reason for the failure of the campaign against female circumcision. We cannot guarantee the right to physical integrity of the girl if we deny this right to his brother.
