Exclusion criteria included monoamnionicity, one\/both twin miscarriage, twin\u2010twin transfusion syndrome, or lethal congenital abnormalities. All twins were managed in multiple pregnancy clinic with standardized protocols. Gestational age\u2010specific IUFD, NND, PND, and neonatal morbidity rates were compared according to chorionicity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three hundred seventy\u2010eight MCDA and 1282 DCDA twins were included. MCDA twins had higher risks of PND (1.9% vs. 0.7% in DCDA twins, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.05), composite neonatal morbidity (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.01), preterm delivery (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01), and low birth weight (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). The prospective risk of IUFD was 0.6% and 0.4% for MCDA and DCDA twins, respectively after 34\u2009weeks' gestation. No NND occurred among deliveries after 30\u2009weeks. The risk of neonatal morbidity of MCDA twins fell from 22.7% at 34\u2009weeks to 2.7% at 37\u2009weeks (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). For DCDA twins, the risk of morbidity fell insignificantly from 36 to 38\u2009weeks (4.0% vs. 3.4%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.60). Logistic regression analysis suggested that the increased risk of perinatal morbidities was related to the higher rate of preterm delivery in MCDA twins rather than chorionicity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>With close fetal monitoring, the risk of late IUFD in twin pregnancies without major complications is low.
