There's a really interesting (and entertaining) documentary called The Great Sperm Race which discusses conception and all the challenges that sperm face in order to fertilize the egg! It's quite entertaining because it's "upped" everything to human size, with a person representing each sperm and its race to the egg.
Watching this documentary, I'm simply amazed that anyone is able to get pregnant at all. The sperm have HUGE obstables to overcome in order to finally get to the egg and fertilize it. One thing that I didn't realize is actually how few sperm make it into the fallopian tube. I won't ruin the ending for you, but I think you might be surprised too!
If you missed The Great Sperm Race on television, you can also watch it on the internet!! Go to it, and get your learn (and laugh) on.
