The invention relates to an efficient gamete/embryo vitrification thawing method.A freezing device used in the method comprises a freezing carrier and spoon-shaped bodies used for containing gametes or embryos.Multiple through holes are formed in the freezing carrier.The spoon bodies are placed in the through holes in the carrier and fixed through fixing assemblies.The number of the spoon-shaped bodies is the same as that of the through holes in the carrier.The method comprises the following steps that A, the gametes or embryos which are protected in a freezing mode are placed to the bottoms of the spoon-shaped bodies under a microscope and then rapidly placed into liquid nitrogen; B, in the liquid nitrogen environment, the spoon-shaped bodies are placed in the through holes of the freezing carriers and fixed through the fixing assemblies; C, the freezing carrier is placed in a support and then placed in a liquid nitrogen tank; D, thawing is performed.The freezing efficiency can be improved, and the cost spent for buying the liquid nitrogen tank and liquid nitrogen is greatly saved.In addition, the spoon-shaped bodies are thick, freezing operation is performed under the microscope, and therefore the phenomenon that the embryos or gametes and oocytes are lost is avoided.
