Coke Adds Life?


Debunked: Coca-Cola is an effective contraceptive

Documented: Coke is acidic, dissolves teeth, etc

Both of these ULs conflate in vitro effects with in vivo effectiveness. Rumour has it that douching oneself with Coca-Cola can prevent pregnancy, because Coke is a potent spermicide. While Coke is acidic (pH 2.5) and does kill sperm in the test-tube, in flagrante there's no way of applying the douche quickly enough to kill sperm. References: Effect of "Coke" on sperm motility.
