There's a good chance that somewhere in the world, someone is telling a pregnant woman that she’s going to have a boy, or a girl, based on how she appears. In the U.S., some favorites are, “You’re carrying low, so it must be a boy,” or, “You don’t have morning sickness? It must be a girl.”
Buzzfeed even has a quiz to help determine if you are going to have a boy, or girl, based on the decorations and cake you’ve chosen for your baby shower. It goes without saying, this is not based on a scientific study.
And, for those who haven’t yet conceived, there are myths about how to prepare the sperm and even the vagina, so you have a boy, or a girl. If you have a boy and you want a girl, or vice versa, and your male partner wears briefs, it’s common to recommend switching to boxers. Or, the other way around, boxer wearers should switch to briefs.
