culturing surplus poor-quality embryos to blastocyst stage have positive predictive value of clinical pregnancy rate
clinical reproductive centers produce large amounts of surplus poor-quality embryos annually, how to maximize the use of these embryos, and which of them have the potential to develop into blastocyst stage and influencing factors were lack of systematic research. objective: to investigate the fate of surplus poor-quality embryos which were cultured to obtain blastocyst, determine the factors wh...
