We disagree with Boyle’s recent article questioning our systematic review in Journal of Sexual Medicine in 2013 (Volume 10, pages 2644-2657). In particular, he disputed the quality ranking we assigned to 7 of the 36 articles that met our inclusion criteria. These had been ranked for quality by the Scottish Intercollegiate Guidelines Network (SIGN) grading system. We found that, “the highest-quality studies suggest that medical male circumcision has no adverse effect on sexual function, sensitivity, sexual sensation or satisfaction.” This conclusion was supported by two randomized controlled trials, regarded as high-quality (1++) evidence and the majority of surveys and studies involving physiological measurements comparing uncircumcised and circumcised men. Here we explain why the 2 randomized controlled trials merit a 1++ ranking and why 4 reports that Boyle believes merit a higher ranking only meet the criteria set down for low quality (2?) evidence according to the SIGN system. We therefore stand by our conclusions. These are supported by a meta-analysis of sexual dysfunctions and by a recent detailed systematic review of the histological correlates of male sexual sensation.
