Recent Medical Studies on CircumcisionCircumcision Policy Influenced by Psychosocial FactorsThe debate about the advisability of circumcision in English-speaking countries typically has focused on potential health factors. The position statements of committees from national medical organisations are expected to be evidence-based; however, the contentiousness of the ongoing debate suggests that other factors are involved. Various potential factors related to psychology, sociology, religion, and culture may also underlie policy decisions. These factors could affect the values and attitudes of medical committee members, the process of evaluating the medical literature, and the medical literature itself. Although medical professionals highly value rationality, it can be difficult to conduct a rational and objective evaluation of an emotional and controversial topic such as circumcision. A negotiated compromise between polarized committee factions could introduce additional psychosocial factors. These possibilities are speculative, not conclusive. It is recommended that an open discussion of psychosocial factors take place and that the potential biases of committee members be recognized.
Circumcision is Not Good Health PolicyA cost-utility analysis, based on published data from multiple observational studies, comparing boys circumcised at birth and those not circumcised was undertaken using the Quality of Well-being Scale, a Markov analysis, the standard reference case, and a societal perspective. Neonatal circumcision increased incremental costs by $828.42 per patient and resulted in an incremental 15.30 well-years lost per 1000 males. If neonatal circumcision was cost-free, pain-free, and had no immediate complications, it was still more costly than not circumcising. Using sensitivity analysis, it was impossible to arrange a scenario that made neonatal circumcision cost-effective. Neonatal circumcision is not good health policy, and support for it as a medical procedure cannot be justified financially or medically.
Circumcision Results in Significant Loss of Erogenous Tissue A report published in the British Journal of Urology assessed the type and amount of tissue missing from the adult circumcised penis by examining adult foreskins obtained at autopsy. Investigators found that circumcision removes about one-half of the erogenous tissue on the penile shaft. The foreskin, according to the study, protects the head of the penis and is comprised of unique zones with several kinds of specialized nerves that are important to optimum sexual sensitivity.
Circumcision Affects Sexual Behavior A study published in the Journal of the American Medical Association found that circumcision provided no significant prophylactic benefit and that circumcised men were more likely to engage in various sexual practices. Specifically, circumcised men were significantly more likely to masturbate and to participate in heterosexual oral sex than uncircumcised men.
Researchers Demonstrate Traumatic Effects of Circumcision A team of Canadian researchers produced new evidence that circumcision has long-lasting traumatic effects. An article published in the international medical journal The Lancet reported the effect of infant circumcision on pain response during subsequent routine vaccination. The researchers tested 87 infants at 4 months or 6 months of age. The boys who had been circumcised were more sensitive to pain than the uncircumcised boys. Differences between groups were significant regarding facial action, crying time, and assessments of pain.
The authors believe that "neonatal circumcision may induce long-lasting changes in infant pain behavior because of alterations in the infant’s central neural processing of painful stimuli." They also write that "the long-term consequences of surgery done without anaesthesia are likely to include post-traumatic stress as well as pain. It is therefore possible that the greater vaccination response in the infants circumcised without anaesthesia may represent an infant analogue of a post-traumatic stress disorder triggered by a traumatic and painful event and re-experienced under similar circumstances of pain during vaccination."
