Facts: The egg cell, or ovum, is the largest and most important cell in the world - and it is only found in women.Although men produce over a million sperm an hour, women are born with a lifetime trove of several million eggs. By adulthood, only about 400,000 remain, and over the course of life, most of the rest - nearly 1,000 a month - are lost. In fact, only 450 of the million egg cells will ever get the chance to become a baby.Everyday of a womans fertile life, several dozen eggs begin developing.Normally only one will complete the development cycle every month - the rest will perish. But the mature eggs get to leave the ovary and take a daring journey down a fallopian tube where it has the chance of encountering elegible sperm.Like a princess fairytale the egg cell has only about a single day to survive before finding a mate - though because sperm cells can survibe for up to 5 day's inside a womans body, a woman can be fertile for nearly a week. But egg cells are monogamous: after one sperm has gotten into its heart, the egg hardens its outer wall to ward off any additional suitorsThere are many obstacles - and fierce competition - to becoming the perfect couple. But if all goes well, and the sperm and egg manage to find each other, it can lead to a miracle match made in heaven.
