my psychology of sex teacher is going to go nuts

Well with cocaine...I don't know what my sperm motility is but I sure as hell can't get it up!

I thought they busted this on Mythbusters, i.e. it didn't do anything to kill or reduce the efficiency of sperm. Though I'm not clear on whether they used Classic Coke (since they generally hide the brands of the products they use) or some other noname brand.

I could "perform" the same tests with lemon juice, Red Bull or Old English 800 and get the same results. Damn that scientific method!

She can't read her own chart. After 1 min in classic coke, sperm had 8.5% motility, according to her own data.

Ok, here is the latest on this from the same group of researchers:

Note the subsequent study unable to repeat their results:

I've seen videos of women with Coke bottles 'up there', now I know it was just a handy form of birth control.

From what I understand the acid in coke is supposed to have some level of spermicide qualities. Along the same lines I seem to remember something about lemons being used as a method of birth control in impoverished nations in Africa and Asia. There are a lot of problems associated with using a douche contraceptive not related to the spermicide's ability to kill sperm. I think the out going message of these videos should always be a condom is 90% more effective.

Was it just me or did this video kind of come across as a 'LOOK HOW BAD COKE IS FOR YOU' video?

Oh, man. Oh man...do NOT mix acid with your coke. Bad juju.

so moral of this video is to wear coke bottle as a condom?

Would upvote for the cool research, but the interrupting opera singing and coke ads annoy me.

Cool research does not exist without opera music.

AS IF the ratio is conservative - in the lab its in a beaker, and mixed until there is 99%+ distribution. In the vagina the sperm would remain against the vaginal wall, and often in a naturally formed "nook" with protection against subsequent liquid flows of carbonated coke fluid (accounting for the fact that it it wouldnt behave like a strict liquid, rather its behavior would be a conglomeration of liquid and expanding gas).

WIKI: Motility is a biological term which refers to the ability to move spontaneously and actively, consuming energy in the process.

If you shoot your load in a coke bottle, you've failed.
