WebRecent studies demonstrated that blastocysts with shorter re-expansion duration (<3 hours) are shown to have higher implantation rate (IR). However, the inclusion criteria … A blastocyst is a cluster of dividing cells made by a fertilized egg. It’s the early stage of an embryo. A blastocyst is one step among many that lead to a pregnancy. A blastocyst forms about five to six days after a sperm fertilizes an egg. Layers of cells in the blastocyst divide and separate. They eventually become the … See more Blastocysts contain chromosomes. If there are chromosomal abnormalities, such as an extra chromosome or a chromosome that’s duplicated or deleted, the blastocyst usually won’t implant in your endometrium.
