OBJECTIVETo evaluate trends of monozygotic twinning after single embryo transfer and its association with patient and treatment factors.METHODSOur retrospective cohort study included 28,596 pregnancies after fresh, nondonor single embryo transfer during 2003\u20132012 reported to the National ART Surveillance System. We examined trends of monozygotic twin pregnancies (number of fetal heart tones on first-trimester ultrasonography more than one or number of neonates born more than one) and assessed patient and treatment factors for monozygotic twin compared with singleton pregnancies. Modified Poisson regression models were used to estimate adjusted risk ratios (RRs) and 95% confidence intervals (CIs) for association between monozygotic twin...
