Methods: Adult mice of Kunming variety were used as experiment animals. After judgement of oestrus, the oestrus period and oestrus stage were determined, and then those mouse were grouped depending on oestrus stage. The mice were dealed with diferrent dosage of PMSG and HCG to make them superovulation, afterwords were mated individually with the male mouse together at same cage. The embryoes were rinsed out and evaluated after 3.5 days when the plug had been seen. The transplant mice were born after the high-quality embryoes were transferred into the receptors mouse uterus at the same oestrus stage which was stimulated by mating with the male mouse which spermaduct had been ligated previously.
