In the embryo transfer process, there are two \"egg flushing\".
The first is the 'flushing of eggs' - oocytes - in superovulation. For in vitro fertilization (artificial insemination).
The second is the flush egg in the embryo collection - embryo, early embryo, fertilized egg. Embryos develop at different times, starting with the fertilized egg.
2, can be combined with the \"gonadotropin treatment of the donor cow is to cause superovulation, so that more embryos can be obtained\" to understand the possible two \"ovulation\".
The flushing of the egg during IVF is to flush the egg from the fallopian tube in order to fertilize it with capacitated sperm in vitro. Egg flushing in embryo engineering is the flushing of an early embryo from the uterus. They are not the same thing.
