BACKGROUND To investigate the fate of surplus poor-quality embryos which were cultured to obtain blastocyst, determine the factors which may influence the blastulation, and discuss their application in predicting of the pregnancy outcomes.METHODS Day3 (D3) after embryo transfer and freezing, surplus poor-quality embryos from IVF/ICSI cycles were cultured to blastocyst by the sequential method, then the blastulation outcomes were observed.Blastulation rates of different female age, etiology, and fertilization technique methods groups were compared; focuses on the influence of blastulation of those blastomeres with different cells number and embryo grade; and last the relationship between the pregnancy outcomes of remained poor-quality embryoswith successful blastulation or failed blastulation groups were studied.
