Melbourne, Dec 19 (ANI): Coca-Cola does not work as a contraceptive, a scientist has cautioned.
Deborah Anderson, a Harvard Medical School researcher, said the soda's acidity does not kill sperm, the Australian Associated Press reported.
The research shatters the belief that the popular drink works as an after-sex Spermicide, reports News.com.au.
Sperm travels very quickly and would reach the cervix before the douche had a chance to work, Anderson said.
She says the soft drink also damages the top layer of cells within the vagina, removes healthy bacteria and makes a woman more prone to sexually transmitted disease.
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. (ANI)
