Embryo Culture Clinical Trial
Official title:
A Prospective Study Comparing the Outcomes of Single Embryo Culture Versus Group Culture in Preimplantation Genetic Testing Cycles
The aim of this study is to analyze whether there is difference in the effect of single embryo culture and group culture in preimplantation genetic screening (PGS) cycle, and provide reference for the feasibility of the clinical application of medium-based noninvasive PGD. This prospective study prepares for more than 1,000 normal fertilized zygotes in each group over one year period. For the recruited patients, all normal fertilized zygotes were randomly allocated into two groups: cultured individually in 25 ul media or 2-3 embryos cultured together in 50 ul media. The blastocyst formation rates, aneuploid rates, clinical pregnancy rates, implantation rates and miscarriage rates will be compared between the two groups.
