Abstract：Objective:To study whether the rates of pregnancy and implantation decline in repeated IVF/ICSI cycles and whether the dechne is associated with the availability of embryo cryopreservation. Methods:We retrospectively analyzed the pregnancy and im-plantation rates of 1 033 IVF/ICSI cycles accomplished in our center to determine the association of the clinical outcomes with the avail-ability of embryo cryopreservation. Results:The rates of pregnancy and implantation declined slishfly in the cycles with embryo cryo-preservation(43% vs 43%,P>0.05;29%I)8 24%,P>0.05),but significantly in the repeated IVF/ICSI cycles without embryocryopreservation(43% vs 35%,43% vs 22%,P<0.05;29% vs 23%,29% vs 16%,P<0.05). Conclusion:The rates of pregnancy and implantation remain similar in the following cycles for those with embryo cryopreservation in the first IVF/ICSI cycles,but decline significantly in the repeated IVF/ICSI cycles for those without.
