Embryo vs Fetus. Embryo and fetus are different stages in the human reproduction process. The human life starts when the sperm and ovum (egg) get together to form the fertilized ovum. Fertilized ovum starts to divide and produce more cells. When it starts to divide in to two cells, 8 weeks from fertilization, the period is called embryo period. The dividing cells collectively forms the embryo.
The big difference between an IVF cycle and a regular menstrual cycle is that ovulation does not take place in an IVF cycle. Instead, the eggs are retrieved at the point of maturation and are fertilized in the IVF lab. Embryos are then transferred to the uterus to initiate pregnancy. Once the embryos are transferred back into the uterus, there is nothing distinguishable between embryos fertilized in the body or in an IVF laboratory.
