Circumcision Increases an Infant's Sensitivity to Pain

Glover’s findings are supported by research on the effects of pain experienced by infants after birth. Anna Taddio, a pain specialist at the Hospital for Sick Children in Toronto, noticed more than a decade ago that the male infants she treated seemed more sensitive to pain than their female counterparts. This discrepancy, she reasoned, could be due to sex hormones, to anatomical differences—or to a painful event experienced in this part of the world by many boys and no girls: circumcision. In a study of eighty-seven baby boys, Taddio found that those who had been circumcised soon after birth reacted more strongly and cried for longer than uncircumcised boys when they received a vaccination shot four to six months later. Among the circumcised boys, those who had received an analgesic cream at the time of the surgery cried less while getting the immunization than those circumcised without pain relief.


Compared to males who are uncircumcised.
