Not surprisingly, this is one of the most frequent questions we encounter. The short answer is, no. Ancient peoples believed in the so-called “law of similarity,” where objects resembling genitalia may possess sexual powers. Ginseng, rhinoceros horn and oysters are classical examples. Oysters also contain high levels of zinc, which can improve overall health and increase sex drive. So there’s no hard evidence that oysters are an aphrodisiac. However, you are assured that your oyster-eating companion has adventurous tastes and an impeccable palate, so what more could you ask for?
