Having trouble getting pregnant?
You heard me. Get yourself a pot of bran right now.
Of course, in a modern sense, this may fall apart in more than one way. Flies and other vermin will be attracted to the bran, even if it's inside the house. It fails to take other things, like obesity, poor diet and age into account, along with a miriad of other conceptual issues.
Not the least of which is getting your man to pee into a pot of bran.
