BOSTON — Deborah Anderson had heard the urban legends about the contraceptive effectiveness of Coca-Cola products for years.
So she and her colleagues put the soft drink to the test ... in the lab.
For discovering that Coke is 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 to oddball but often surprisingly practical scientific achievements.
The ceremony at Harvard University, in which Nobel laureates bestow the awards, also honored a British psychologist who found foods that sound better taste better; researchers who discovered exotic dancers make more money when they are at peak fertility; and two Brazilian archaeologists who determined armadillos can change the course of history.
Anderson, a professor of obstetrics and gynecology at Boston University's School of Medicine, and her colleagues won the chemistry Ig Nobel for finding that Coca-Cola is a spermicide and that Diet Coke works 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," Anderson said, adding she does not recommend using Coke for birth control.
Some Taiwanese doctors also 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.
A Coca-Cola spokeswoman refused to comment.
The other award winners:
Nutrition: Massimiliano Zampini and Charles Spence for demonstrating that food tastes better when it sounds better.
Peace: The Swiss Federal Ethics Committee on Non-Human Biotechnology and the citizens of Switzerland for adopting the legal principle that plants have dignity.
Archaeology: Astolfo Gomes de Mello Araujo and Jose Carlos Marcelino for showing armadillos can scramble the contents of an archaeological dig.

Biology: Marie-Christine Cadiergues, Christel Joubert and Michel Franc for discovering that fleas that live on a dog can jump higher than fleas that live on a cat.
Medicine: Dan Ariely for demonstrating that expensive fake medicine is more effective than cheap fake medicine.
Cognitive science: Toshiyuki Nakagaki, Hiroyasu Yamada, Ryo Kobayashi, Atsushi Tero, Akio Ishiguro and Agota Toth for discovering that slime molds can solve puzzles.
Economics: Geoffrey Miller, Joshua Tyber and Brent Jordan for discovering that exotic dancers earn more when at peak fertility.
Literature: David Sims for his study "You Bastard: A Narrative Exploration of the Experience of Indignation within Organizations."
