  1. Perinatal outcomes among singletons following assisted reproductive technology compared with spontaneous pregnancy Third affiliated Hospital of Zhengzhou University Henan China Yichun Guan Reproductive Medicine Center

  2. Third affiliated Hospital of Zhengzhou University Henan China Objective: This study was performed to compare perinatal outcomes and placental efficiency of singleton conceived from ART with spontaneous pregnancy. Third affiliated Hospital of Zhengzhou University

  3. Third affiliated Hospital of Zhengzhou University Henan China Material and Methods:In this retrospective cohort study which was performed in the Third Affiliated Hospital of Zhengzhou University, 3991 singleton conceived from ART and spontaneous pregnancy were enrolled: ART group (n=1004) and spontaneous pregnancy group (n=2987). Baseline data and perinatal outcomes information including demographic data, gestational age, preterm labor, and intrauterine growth retardation (IUGR), postpartum hemorrhage, neonatal outcomes were recorded. Moreover, the age-stratified analysis was performed. Third affiliated Hospital of Zhengzhou University

  4. Third affiliated Hospital of Zhengzhou University Henan China Result(s): Gestational age, cesarean section, premature rupture and placenta previa were significantly higher in ART group compared to spontaneous pregnancy group. However, there were no significant differences between groups in terms of other factors such as hypertensive disorder during pregnancy, abnormal glucose metabolism, gestational cholestasis, pregnancy with thyroid dysfunction, pregnancy with anemia, streptococcal infection and postpartum hemorrhage and other pregnancy complications .

  5. Third affiliated Hospital of Zhengzhou University Henan China Result(s): For neonatal outcomes, severe asphyxia mobidity was higher in the ART group than spontaneous pregnancy group. Compared with the spontaneous pregnancy group, placental weight was higher and placental efficiency was lower in ART group . Moreover, age-stratified analysis: in the group of age＜35, the average birth weight, low birth weight rate, neonatal severe asphyxia rate, placental weight and placental efficiency were significant higher in the ART group However, in the group of age≥35, there were no differences between groups . Third affiliated Hospital of Zhengzhou University

  6. Third affiliated Hospital of Zhengzhou University Henan China Conclusion: The perinatal outcomes among singletons following ART is relatively safe, although ART affects placental efficiency. In elder group, age has a predominant effect on perinatal outcome. Third affiliated Hospital of Zhengzhou University
