简介：AbstractObjective:To evaluate the effect of morphologic factors on survival rate (SR), pregnancy rate (PR), and implantation rate (IR) of human embryo vitrification following frozen embryo transfer (FET) on day 3 post-ovulation.Methods:Women undergoing FET (n = 921) with embryos cryopreserved by vitrification between 2012 and 2013 were enrolled in this retrospective cohort study.Results:Embryos with >9 blastomeres yielded the highest SR of 100%. Lower SR was observed in embryos with 5 to 6 (57.5%) and 4 blastomeres (41.4%). In terms of blastomere symmetry, the SR of embryos with equally sized blastomeres was significantly higher than that of embryos with unequally sized cells (82.5% vs. 64.6%, P < 0.05). As fragmentation increased, SR decreased from 92.1% to 20.6% (P < 0.05). Significant differences were observed among groups when analyzing PR and IR according to the 3 embryonic parameters before vitrification. Embryos with 13 to 16 blastomeres yielded the highest PR (39.5%) and IR (24.1 %). The PR and IR of embryos with blastomeres of equal size were significantly higher than those with unequally sized blastomeres (36.5% vs. 21.7%, 23.7% vs. 12.4%, P < 0.05). After warming, embryos with 13 to 16 blastomeres yielded the highest PR and IR (40.9% and 24.2%, respectively). The PR and IR were observed to grow with an increase in the percentage of intact blastomeres (23.2%-38.2%, 14.2%-23.2%).Conclusions:These results show that vitrification methods do not effectively improve survival outcomes for embryos of poor quality and it is needed to develop a comprehensive vitrification protocol that considers all the practical aspects, including the current limitation regarding cleavage-stage embryos of poor quality.

简介：1．poor用作形容词，意为“贫困的，贫穷的”，用于指长期或临时处于贫困状态的人，也可指那些被认为没有足够钱的人。

简介：对于“poor”这个单词，不同的人有不同的理解。单纯把它翻译成中文，即“贫穷的，虚弱的，差的”。是的，它的本意如此，这是最普通的定义，而我们通常也只看到最普通的这一种。然而把它分解开来，便可以发现潜藏其中的秘密。
