对1211例首次体外受精(IVF)周期的患者进行跟踪观察，并对3个周期后的累计妊娠率(CPR)进行评估。对体外受精失败后停止治疗的患者和没有怀孕但继续进行下一个周期的患者的第一个周期进行了受精率比较，并比较了不良治疗结果的预测因素的出现：卵子产量小于或等于2，以及替换
The validity of the cumulative pregnancy rate (CPR) calculated by lice-table approach, obtained in a transport in-vitro fertilization (IVF) programme, was tested by the determination of possible influence of selective drop-out of patients with a poor treatment prognosis, A cohort of 1211 patients who had a first IVF cycle was followed, and the CPR after three IVF cycles was assessed. First cycles of patients who discontinued treatment after failed IVF, and of those who did not achieve a pregnancy but proceeded to a subsequent cycle, were compared for fertilization rate and for occurrence of prognosticators of poor treatment outcome: oocyte yield less than or equal to 2, and replacement of
