When the sperm die in the race:

“Some of you may die but it is a sacrifice I am willing to make.”

new research has shown that "there is ample evidence to show that as millions of human sperm cells swim towards a waiting ovum or egg, only one gets to fertilize it. Now, a new study shows that even though the fastest and most capable sperms reach the ovum first, it is the egg that has the final say on which sperm fertilizes it."

so basically we could have almost been exterminated by the egg if they considered us "unworthy".
