Myth Busters – Is Coca-Cola a Contraceptive?

The Mythbusters team approached Dr. Turek, an expert in sperm biology, to help them figure out how Coca Cola irrigation of the female reproductive tract after sex could be a contraceptive. They wanted to better understand if there was any biological basis for a Coca Cola “contraceptive effect”. On reviewing their “scientific” experiments, Dr. Turek helps them come to the conclusion that Coca Cola does not necessarily kill sperm on contact (water does a better job of that), but with the help of its carbonated properties, simply washes the sperm out of the female reproductive tract. The Coca Cola “contraceptive effect” myth is… busted!
