then you HAVE to watch The Great Sperm Race, it's amazing!
Here's part 1...there's 6 parts on youtube, it's really amazing to see how so much goes against you having a baby even when you're perfectly healthy and fertile.
It's really cool though, they used people as sperm and places as the vagina, cervix, uterus and fallopian tubes so you can really see the crazy journey sperm have to take to get to the egg blown up to human size.
I learned a few things in the video too, random facts like:
*A man produces about 1,000 sperm with every heartbeat.
*The "entryway" into the fallopian tube is only about 3 sperm-head wide
*Out of the millions and millions of sperm that get ejaculated only a couple make it alive to the egg!!!
It's a good watch!
