If you thought Coca-Cola could work as a contraceptive, think again.
Deborah Anderson, a Harvard Medical School researcher, said the soda’s acidity does not kill sperm, the Australian Associated Press reported.
Many women in third-world countries use the soft drink as an after-sex douche, hoping to kill sperm. The belief held true in America until the 1960s.
Sperm travels very quickly and would reach the cervix before the douche had a chance to work, Anderson said.
Another reason not to try this: The beverage could damage the vagina’s top layer of cells, removing healthy bacteria, thus, allowing women to become vulnerable to sexually transmitted diseases, Anderson said.
