The current trend in human in vitro fertilization/embryo transfer (IVF/ET) protocols is to decrease the rate of multiple pregnancies after multiple embryo transfer with maintaining the pregnancy rate at admissible levels (according to laboratory standards). Assessment of morphological feathers as a reliable non-invasive method that provides valuable information in prediction of IVF/intra cytoplasmic sperm injection (ICSI) outcome has been frequently proposed in recent years. This article describes the current status of morphological embryo evaluation at different pre-implantation stages.}, keywords = {Embryonic development,Cleavage Stage,Fertilization,Zygote,Blastocyst}, url = {https://www.celljournal.org/article_250237.html}, eprint = {https://www.celljournal.org/article_250237_187fa6700cfd05981e39a39c9d94e4ed.pdf} }
