The blastocyst is a hollow cellular mass generated during early development and composed of cells forming the trophectoderm, the inner cell mass, and the fluid-filled cavity.
A blastocyst is a dividing cell cluster produced by a fertilized egg.
A blastocyst forms about five to six days after a sperm fertilizes an egg.
It implants in our uterine wall and develops into an embryo, then a foetus.
For in vitro fertilization (IVF), the blastocyst stage of a fertilized egg is crucial.
Pregnancy will not occur if the blastocyst does not implant in the endometrium of the woman.
