description Rising cesarean rates call for review of the indications for this procedure. Suspicion that subtle operatives, not reflected in morbidity and mortality rates, might be present inspired the study presented here. Three hundred fifty-two cesarean operations were done at Huron Road Hospital in the years 1952-1954. Examination of family records identified 97 probands delivered by cesarean after prolonged active labor before or during that period. Research efforts yielded 54 cases that were free of complications and had full historic data for both proband and sibling(s) of the same parentage, totaling 122 children. The intelligence quotient (IQ) scores of these families compared with that of the proband undergoing successive hours of labor suggested a detrimental effect of increasing length of trial labor. Statistical analyses of the 30 families in which the probandsʼ trial labors exceeded 12 hours support that notion, as the probands had significantly lower IQ scores than their siblings born by elective cesarean with no labor (P=.006 to P
