Abstract
Pregnancy rates per cycle reported from different in vitro fertilization-embryo transfer programs vary widely. While several programs have reported constant pregnancy rates per cycle, others report declining pregnancy rates. Selection biases at the point of entry and between cycles are discussed as possible explanations of these discrepancies.
摘要
不同体外受精-胚胎移植项目报告的每个周期的妊娠率差异很大。虽然有几个项目报告每个周期的妊娠率保持不变，但其他项目报告妊娠率在下降。入组时和周期之间的选择偏倚被作为这些差异的可能解释进行了讨论。
