We investigated associations between prenatal OP pesticide exposure and fetal size and modification by fetal sex. Maternal urinary concentrations of dialkyl phosphate (DAP) metabolites were measured at 3 time points. Fetal biometrics were obtained from ultrasounds in the second (n\u00a0=\u00a0773) and third (n\u00a0=\u00a0535) trimesters. Associations between pregnancy-averaged \u03a3DAP and fetal biometry z scores were determined through multiple linear regression. Modification by sex was investigated through stratification and interaction. In the second trimester, one ln-unit increase in \u03a3DAP was associated with lower estimated fetal weight (\u20130.15 SD; 95% CI, \u20130.29 to \u20130.01), head circumference (\u20130.11 SD; CI, \u20130.22 to 0.01), biparietal diameter (\u20130.14 SD; CI, \u20130.27 to \u20130.01), and abdominal circumference (\u20130.12 SD; CI, \u20130.26 to 0.01) in females. In the third trimester, one ln-unit increase in \u03a3DAP was associated with lower head circumference (\u20130.14 SD; CI, \u20130.28 to 0.00) and biparietal diameter (\u20130.12 SD; CI, \u20130.26 to 0.03) in males. Our results suggest that prenatal OP pesticide exposure is negatively associated with fetal growth in a sex-specific manner, with associations present for females in mid-gestation and males in late gestation.<\/jats:p>\n               <jats:p>This article is part of a Special Collection on Environmental
