Abstract: Fertilization is a precise and highly coordinated physiological process in mammals. Sperm-egg fusion is the most critical step. Two highly differentiated haploid gametes, sperm and egg, fuse to form a new zygote, and develop into an embryo. Izumo1 and Juno were the first ligand-receptor proteins, which were found on the plasma membrane of sperm and egg. Their interaction is necessary for sperm-egg recognition. This paper reviews the discovery process of the two important proteins, their interaction during sperm-egg fusion and the latest research progress in mammalian fertilization.
