The embryo is present at five to six days after the zygote is fertilized. The embryo is a clump of cells inside the formerly hollow blastocyst, and is surrounded by the trophoblast.

Early development and implantation of the embryo. A. The zygote stage begins upon fertilization of the secondary oocyte by the sperm. The zygote contains both pro-nuclei and is contained within the zona pellucida, until the blastocyst stage. B. The morula stage.. The blastocyst stage.
