Fertilization takes place when an egg cell and a sperm cell recognize one another and fuse to form an embryo. Researchers said on Wednesday they have identified a protein on the egg cell's surface that interacts with another protein on the surface of a sperm cell, allowing the two cells to join. This protein, dubbed Juno in honor of the ancient Roman goddess of fertility and marriage, and its counterpart in sperm, named Izumo after a Japanese marriage shrine, are essential for reproduction in mammals including people, they said.</p><br clear="all"/>
