Brief summary

The purpose of this study is to explore a method to identify the viability of day-3 poor quality embryos

Detailed description

Day-3 poor quality embryos are related to significant lower clinical pregnancy,so freezing numerous poor quality embryos are clinical impractical. To ensure the successful pregnancy and to enhance the availability of the poor quality embryos, day-3 poor quality embryos are further cultured to different developmental stage and then cryopreserved. The viability of these embryos are tested in frozen-thawed transfer.
