4. Royal Jelly. Bee fertile! Royal jelly has been used for centuries by women looking to get knocked up. Said to be good for hormonal balance, royal jelly is actually the milky substance secreted from the glands of worker bees and — this is what makes it royal — is the only food ever eaten by the queen bee. Weird, we know, but it’s said to be super high in nutritional content and many believe it’s what behind the queen bee’s ability to lay approximately 2,000 eggs per day. Now, that’s fertile.
