These germ cells will remain in their arrested state until the child-bearing years arrive. Then hormones will cause only a few hundred of them to resume their meiotic progression. Every month one of these will be ovulated, just after it completes its first meiotic division. Where eggs are concerned, the two cells that result from this division are dramatically different in size from one another (rather than the same, as symbolized for sperm in Figure 5).
