The aim of this study is to assess the many different parameters involved in the incidence of multiple pregnancies, such as maternal age, stimulation, endometrium, receptivity and the quality of the transferred embryos. During a 3.5 year period, 86 pregnancies were recorded in our IVF unit. A single gestational sac was identified by early ultrasonography in 67 patients, while in 19 others, multiple sacs were noted. Patient characteristics, treatment cycles and embryology results were similar in the two groups. When the number of transferred embryos was kept similar in both groups, EIR was found to be a valuable prognostic determinant for multiple pregnancies in IVF.
本研究的目的是评估多胎妊娠发生率所涉及的许多不同参数，如产妇年龄、刺激、子宫内膜、接受性以及移植胚胎的质量。在3.5年的时间里，我们的体外受精（IVF）单元记录了86例妊娠。67例患者通过早期超声检查发现有单个妊娠囊，而另外19例则发现有多个妊娠囊。两组患者的特征、治疗周期和胚胎学结果相似。当两组移植胚胎数量保持相似时，发现胚胎植入率（EIR）是体外受精中多胎妊娠的一个有价值的预后决定因素。
