They call up to a 7.6% chance of adverse event due to circumcision low rate. And the list of complications is not pleasant to any man. Any sensible person should stay away.

Circumcision is associated with risk, but rates of complication were low in hospital or clinical settings. Across the three studies, adverse events (AEs) were infrequent (1.5%–7.6%) and included infection, bleeding, hematoma, wound dehiscence, swelling, anesthetic reactions, inadequate tissue removal, pain, penile damage, erectile dysfunction, and dissatisfaction regarding appearance. Men in the intervention arms of the three studies experienced AE rates of 1.5%, 3.8%, and 7.6% across the Kenyan, South African, and Ugandan trials, respectively. Although the overall rate for AEs in the Ugandan trial was higher, the moderate AE rate (3%) was comparable to the other two studies.
