4. The egg makes the decisions. For a long time, biology textbooks told the same story: Sperm were the active heroes of fertilization, racing toward a passive egg, determined to break in and claim victory. But that story is wrong. As early as the 1980s, researchers discovered that the egg is far from passive when it comes to the fertilization process. In fact, it's making the decisions. "The egg chooses when and if the wriggling sperm can break in."
