Coca-cola as a contraceptive?

Having heard the urban legends about the contraceptive effectiveness of Coca-Cola products for years, Deborah Anderson, , a professor of obstetrics and gynecology at Boston University's School of Medicine, decided to put the soft drink to the test.

For discovering that Coke is indeed a spermicide, Anderson and her team are among this year's winners of the Ig Nobel Prize, the annual award given by the Annals of Improbable Research magazine for oddball but often surprisingly practical scientific achievements.

Anderson and her colleagues found that not only was Coca-Cola a spermicide, but that Diet Coke for some reason worked best. Their study appeared in the New England Journal of Medicine in 1985.

"We're thrilled to win an Ig Nobel, because the study was somewhat of a parody in the first place," said Anderson, who added that she does not recommend using Coke for birth control purposes.

A group of Taiwanese doctors were honored for a similar study that found Coca-Cola and other soft drinks were not effective contraceptives. Anderson said the studies used different methodology.
