Abstract：Objective This study aims to evaluate the pregnancy outcomes of twins after in vitro fertilization (IVF-ET) and to compare with those of the natural twins.Methods 172 pairs of twins after IVF-ET and 476 pairs of natural pregnancy twins were selected as the study subjects in a hospital in Beijing. Data on maternal age, length of gestation, delivery mode, pregnancy complications, and neonate health were retrospectively analyzed, and were compared between the two groups.Results The average maternal age in the IVF-ET group was older and the gestational length was shorter (P＜0.05) in the IVF-ET group than in the natural pregnancy group. The proportions of elderly parturient women, cesarean delivery, history of threatened abortion, placenta previa, and pregnancy with hypothyroidism in the IVF-ET group were higher than those of the natural pregnancy group (Ps<0.05). The ratio of the discordance rate over than 25% in the IVF-ET group was 7.0%, higher than that of the natural pregnancy group (P<0.05).Conclusion Postoperative IVF-ET twins in pregnant women and fetal monitoring should be strengthened, so as to prevent pregnancy complications and maternal and neonatal undesirable outcomes.
