Critical evaluation of arguments opposing male circumcision: A systematic review

OBJECTIVE

To systematically evaluate evidence against male circumcision (MC).

METHODS

We searched PubMed, Google Scholar, EMBASE and Cochrane databases.

RESULTS

Database searches retrieved 297 publications for inclusion. Bibliographies of these yielded 101 more. After evaluation we found: Claims that MC carries high risk were contradicted by low frequency of adverse events that were virtually all minor and easily treated with complete resolution. Claims that MC causes psychological harm were contradicted by studies finding no such harm. Claims that MC impairs sexual function and pleasure were contradicted by high-quality studies finding no adverse effect. Claims disputing the medical benefits of MC were contradicted by a large body of high-quality evidence indicating protection against a wide range of infections, dermatological conditions, and genital cancers in males and the female sexual partners of men. Risk-benefit analyses reported that benefits exceed risks by 100-200 to 1. To maximize benefits and minimize risks, the evidence supported early infant MC rather than arguments that the procedure should be delayed until males are old enough to decide for themselves. Claims that MC of minors is unethical were contradicted by balanced evaluations of ethical issues supporting the rights of children to be provided with low-risk, high-benefit interventions such as MC for better health. Expert evaluations of case-law supported the legality of MC of minors. Other data demonstrated that early infant MC is cost-saving to health systems.

CONCLUSIONS

Arguments opposing MC are supported mostly by low-quality evidence and opinion, and are contradicted by strong scientific evidence.

Are mechanical and chemical trauma the reason of meatal stenosis after newborn circumcision?

Mechanical and chemical trauma are a widely accepted theories to explain the pathogenesis of meatalstenosis after newborn circumcision. The aim of the present study was to explore the theory that an exposed glans is prone to meatal stenosis. This was done by a novel investigation of boys who were born with "hooded prepuce", a condition in which the glans is completely exposed. Physical examination, lower urinary tract symptoms, urethral meatus configuration, and surgical procedures of 18 children admitted for routine circumcision, who had congenital hooded prepuce with normally located urethral meatus, were analyzed. The study period was 2013 and 2018. All the cases have been seen because of neonatal circumcision request, but was postponed due to hooded prepuce. The only presenting complaint in children was a cosmetically unattractive appearance. There were no symptoms associated with meatal stenosis, they circumcised in an average of 6 years and non of them required any additional procedure.Conclusion: Meatal stenosis did not occur in cases whose glans penis are naked with hooded prepuce. These findings do not support the default chemical and mechanical trauma theories. Hooded prepuce without any penile anomalies is only a cosmetically unattractive appearance and circumcision can correct this. What is known: • The common theory of meatal stenosis etiology is that the meatus undergoes irritation with chemical/mechanical trauma in the absence of a prepuce after newborn circumcision. • Circumcision is usually postponed in newborns with hooded prepuce. What is new: • We did not notice meatal stenosis in cases whose urethral meatus were not covered with a prepuce congenitally. Ammoniacal dermatitis or mechanical trauma theories may not explain the cause of meatal stenosis. • Hooded prepuce is not a handicap to newborn circumcision. It is just a cosmetic problem and circumcision can solve it.
