‘Sizing Up Sperm' is a Life Size Look At Making Humans

Ok, this is cool. This is very very cool. Looks like National Geographic has gone ahead and made a documentary that details the voyage--nay, the crusade--sperm must go on in order to get the job done. And it is all done in life size form, with actual people representing individual sperm. It's not surprising that I want to see ‘Sizing Up Sperm.'

I always knew it was a tough journey for the little guys, but I never knew it was this tough. Seriously, the voyage they undertake is epic, and well, worth watching. Check out the gallery for stills of ‘Sizing Up Sperm.'
