Then, the process of becoming pregnant takes several days â the fertilized egg (now called a blastocyst) has only just begun its long journey. Once the egg is fertilized, it now has to travel all the way up into the uterus for implantation to take place.
Background Information. Fertilization of an egg by a sperm occurs soon after its release from the ovary (ovulation) into the fallopian tube to form a single cell embryo (zygote) containing the genetic material of the sperm and egg. The zygote then divides progressively into a multi-cell embryo. When the embryo contains about 12-16 cells, it is called a morula. After 5-6 days, the embryo contains many cells and forms a cystic cavity termed the blastocoel within its center. At this stage, the embryo is called a blastocyst and has undergone the 1st step in differentiation; it separates into two tissue types, the trophectoderm and the inner cell mass.
