Medically unnecessary penile circumcision (MUPC) performed on a non-consenting child has been the subject of increasing critical attention in recent years. This paper provides a behind-the-scenes narrative of the politics of ethical policymaking in the United Kingdom in this area including a discussion about some potential barriers to reform. After a brief overview of ethical guidance for medically unnecessary surgical procedures on children in general and on their genitalia in particular, the paper takes a closer look at three contemporary documents (...) released by UK medical bodies and highlights the unique ethical and safeguarding contradictions in this area. The outcomes of initiatives aimed at engaging constructively with the medical bodies and encouraging wider debate are then described, along with some of the main obstacles to engagement and counter-arguments employed. MUPC is subsequently discussed in a wider societal context, highlighting why serious safeguarding concerns have been raised about what many people believe to be a harmful, preventable practice hiding ‘in plain sight’. The paper ends by calling for UK MUPC guidance to be made consistent with the body of guidance that UK doctors are expected to follow. (shrink)
