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.
The other sperm die within 48 hours. The fertilized egg is now called a zygote. The depolarization caused by sperm penetration results in one last round of division in the egg's nucleus, forming a pronucleus containing only one set of genetic information.The pronucleus from the egg merges with the nucleus from the sperm.Once the two pronuclei merge, cell division begins immediately. The dividing zygote gets pushed along the Fallopian tube. Approximately four days after fertilization, the zygote has about 100 cells and is called a blastocyst.When the blastocyst reaches the uterine lining, it floats for about two days and finally implants itself in the uterine wall around six days after fertilization.he pronucleus from the egg merges with the nucleus from the sperm.
