Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
