This paper examines how the medicalization of male circumcision in Turkey has, over more than a century, transformed the young male body from a physical body to an affective body. Two main forms of medicalization can be observed in the history of male circumcision: biomedicalization and psychologization. The biomedicalization of male circumcision during the developmentalist era (1960s-1980s) rested upon the notion of a physical body whose physical pain could be eliminated by medical professionals via medical instruments. In contrast the psychologization of male circumcision that has emerged during the neoliberal era (1980s-present) regards the young male body in male circumcision as a body that is vulnerable to psychic pain/trauma and medical professionals have incorporated this affective body into the consumer body, whose comfort and pleasure they seek to meet.
