目的：描述IVF后单卵双胎妊娠（MZT）的发生率、绒毛膜性、单卵性和妊娠结局。设计：回顾性研究。设置：大学生育中心。患者：2000年至2007年4，976例临床妊娠中发生的自体妊娠和卵母细胞捐献IVF周期。干预：无。主要结局指标：MZT发生率、绒毛膜性、接合性、妊娠结局。结果：98例MZT在孕早期超声评估后被诊断（发生率为2%）。移植自体卵母细胞的周期发生率为1.7%，而移植供体卵母细胞的周期发生率为3.3%;然而，
Objective: To characterize incidence, chorionicity, amnionicity, and pregnancy outcome for monozygotic twin pregnancy (MZT) after IVF.Design: Retrospective review.Setting: University-based fertility center.Patient(s): Autologous and oocyte donation IVF cycles eventuating in 4,976 clinical gestations from 2000 to 2007.Intervention(s): None.Main Outcome Measure(s): MZT incidence, chorionicity, zygosity, pregnancy outcome.Result(s): Ninety-eight MZTs were diagnosed after first-trimester ultrasound evaluation (2% incidence). The incidence in cycles transfering autologous oocytes was 1.7% but was 3.3% with donor oocytes; however, women
