Suddenly, I have a rip-roaring interest in reproductive biology. Weird, huh?
Anyway, so I've learned a lot of this stuff before. (If by "learned" you mean memorized it until I didn't need to know it anymore and then "poof," out it went.)
But holy shit, man! I'm reading about all the stuff that sperm has to get through in order to fertilize an egg, and all I can picture is like a scene from Indiana Jones! Flames, tumbling boulders, snake pits, oh my!
And it's so stupid because like I said, I KNOW how all of this works - but no biology teacher of mine ever described how the immune system attacks sperm because it's a foreign invader, and that all these sperm cells get stuck to the walls of the reproductive tract while others lose their protective sheath and keep going, and when they get to the egg they have to penetrate it in just the right spot otherwise it doesn't work, and then once inside the egg releases a hormone or something that creates like a force field of (calcium?) ions so no other sperm can get inside, and if 2 sperm cells DO get inside, everything DIES!
Seriously, blew my fucking mind.
I know most of you are in biomed and the like and are probably thinking "Really? This girl made it through college without knowing this shit?" In my defense, my biology courses were always super concerned with photosynthesis, cell respiration, meiosis and mitosis, etc. My best mental representation of reproductive biology came from the movie Look Who's Talking. Remember that movie?
Clip #1: Until now, that was the most vivid scene of reproduction I've ever had in my head.
Compare that to this:
Clip #2: An accurate representation of JLK's instruction in reproductive biology. LAME!!!!
It's really too bad that I didn't take more than 2 biology courses in college, because right now I am so tempted to switch over to fertility studies.
