Fertilization is the union between the egg and the sperm to create a new being: the embryo, which will develop during pregnancy. Implantation, on the other hand, is the process by which the embryo enters the endometrium (the layer that lines the uterus internally) in order to form the placenta and thus be able to nourish and grow during pregnancy.
