Top 10 Aphrodisiacs

#6 - Oysters

Many foods (bananas, asparagus, carrots, avocados) are considered aphrodisiacs because they resemble the penis or testicles. Oysters resemble a vagina. The Romans placed the oyster high on their list of prized aphrodisiacs. Casanova, the legend goes, would eat 50 raw oysters for breakfast. Yet interestingly, oysters (and pine nuts, another ancient aphrodisiac) are high in zinc, which is necessary for sperm production. Raw oysters are also high in D-aspartic acid and N-methyl-D-aspartate, which increased testosterone levels in one study on male rats, which could in theory increase libido, according to Karen Boyle of Johns Hopkins Hospital. "The data is questionable and mixed, but oysters do make a nice appetizer," she said.
