Early blastulation of day 4 embryo correlates with the increased euploid rate of preimplantation genetic screening cycles

摘要

Objective: It is known that embryos with faster growing potential, especially in blastocyst development, correlate with the increased euploid rate. Our study investigated the preimplantation genetic screening cycle to analyze the correlation between early blastulation (EB) on day 4 embryo and the euploid rate.
