Coke may be it, but it isn’t an effective spermicide, according to a new study by serious doctors in white coats.
Coca-cola was used as an after-sex spermicide in America until the 1960s, and is still used by many women in third world countries today as an after-sex douche.
The Harvard research team found that Coca-Cola was only able to immobilize only 30 percent of the sperms within an hour. Ironically coca-cola douches increase the forward velocity of healthy sperm by almost 18 cm/hour, actually increasing the chances of striking a baby using the method.
The other bad news, like teeth the Coke also damages the vagina, increasing the risk of getting cavities catching sexually transmitted diseases.
