9 Historical Methods for Determining the Sex of an Unborn Baby
Are you pregnant?
Do you like eating poultry and venison, and talking about jousting and knight stuff? Well, then you’re obviously carrying a boy. Like dancing and music? It’s a girl.
Sure, it’s not the most scientific of determinations, but for women living in a world before ultrasounds, there was no way to tell just what or who or how many were in there. Modern technology has made a window into a place which, for hundreds of thousands of years, only speculation illuminated.
So, if you don’t have the benefit of that window (which, by the way, isn’t always clear), how did you tell whether you were carrying a boy or a girl? And perhaps even more important, could you choose which?
Before we get to the good stuff, here’s a quick Bio 101 primer on how it really works: Human sex differentiation is dictated by the XX/XY system. The egg cell (we’ll call her Sally) contains one lady-making X chromosome; the sperm (let’s call him Harry) can carry either an X or a Y chromosome. When Harry meets Sally (see what we did there?), whether they’ll make a boy or a girl is dependent on which chromosome Harry’s packing. The Y chromosome stimulates testis formation in the fetus, and thus male sexual development; no Y chromosome, the gonads become ovaries and you’ve got yourself a girl. Pretty simple (except when there’s an anomaly, such as Klinefelter’s syndrome, an extra X chromosome attached to the XY that can manifest in decreased fertility, increased breast tissue, and other ways). The sex of the infant is set, though possibly not in stone, as soon as the sperm fertilizes the egg, but the sexual bits don’t develop for several weeks. Most parents don’t find out their baby’s gender until the 20-week scan, if they do find out at all.
1. Ways to Game the System
So making a boy or a girl the old fashioned way is a bit of a crapshoot—it’s whichever sperm survives the cervical gauntlet. Nowadays, fertility specialists can make and identify embryos of either sex, but it’s generally frowned on (and illegal in the UK, except in cases in which you have a serious genetic condition that you risk passing on to a child of a certain sex).
But not really having a ton of control over the situation didn’t and doesn’t stop women from trying to game the system. The Distaff Gospels is a collection of medieval European women’s medical lore recorded in the late 15th century; it’s also responsible for the above gender stereotyping about jousting and dancing. The Gospels recommended having the man turn his face towards the east during sex if the couple is trying for a boy; to have sex in the morning if you’re aiming for a boy and in the evening and night if you want a girl; or not to have sex right after a meal if you want a boy. Another medieval source recommends that the gentleman quaff a cocktail made of red wine and pulverized rabbit’s womb, while the lady do shots of red wine and dried rabbit’s testicles.
Of course, if you want to try for a particular sex (say, if you’re modern royalty tasked with producing a son and heir), then there are couple things that you can do. There’s the Shettles method, based on the notion that Y-toting sperm are faster swimmers than X-toting sperm, but don’t live as long. If you want a boy, then, you should try to have sex as close as possible to ovulation, to give the male sperm a fighting chance; if you want a girl, you should have sex two to four days before you ovulate. There’s also the Whelan method, which is kind of the opposite: If you want a boy, you should have sex four to six days before you’re about to ovulate and if you want a girl, two to three days before. The Whelan method is predicated on the idea of basal body temperature affecting sex determination.
Once the egg is fertilized, however, how do you know what you’ve got in there without the benefit of a window?
2. The way you walk
Walk with your right foot first, you’re having a boy; the opposite, you’re having a girl. This was according to the Distaff Gospels again—a wonderful source for medically questionable stunners, some of which were, if not exactly prescient or accurate, at least well-intentioned: For example, the Gospels cautioned that if at the hour of conception, “neither feels affectionate love for the other, a female of bitter disposition is born.”
3. The salt test
The Gospels again: “When a woman is carrying a child and she wishes to know whether she is carrying a boy or a girl, you should sprinkle salt on her head while she is sleeping, so gently that she is unaware of it. When she wakes, note what name she says first. If she says a man’s name it will be a boy and if she says a woman’s name it will be a girl.” Or maybe she’ll just wake up saying the name of the weirdo who put salt on her head.
4. Ask Mom
“If a pregnant woman wants to know the gender of the child she is bearing, listen to her and she will reveal it herself,” the Gospels said. “When she asks: ‘What do you think I am carrying?’, if you say: ‘A lovely boy’, and she does not blush, you should know for sure that she will have a girl.”
Blushing aside, there is some evidence that women have a sort of mother’s intuition about what’s going on in there: According to The Sun, a study found that women with no prior knowledge of their baby’s gender guess the sex correctly 71 percent of the time. Presumably, these researchers did not ask the mothers-to-be by using the “key test”—place a key in front an expecting mother and if she grabs it by the fat end, she’s having a boy, and by the narrow end, a girl.
5. Morning sickness
This is one of those old wives’ tales that is not only literally an old wives’ tale (the women in the Distaff Gospels were old and wives), but is also believed today—the idea that how and when you are sick when you’re pregnant can give some clue as to whether it’s a boy or a girl. According to the Gospels, you’re sicker in the first three months with a girl than with a boy, but a boy causes pain after the first trimester. But according to current medical professionals, if you suffer badly from morning sickness (a horrible misnomer if there ever was one) or are ill throughout your pregnancy, you’re more likely to be carrying a girl.
6. Fat daddy?
According to myth, if the father piles on the pounds during the mother’s pregnancy, then she’s carrying a girl; interestingly, Danish researchers conducted a study of 100 fathers-to-be and discovered that indeed, those who had little girls were heavier at their births than those who had boys.
7. Sweet or sour?
Because girls are naturally sweet, if you’re carrying one, you’ll crave sweet foods; boys, being made of snips and snails and puppy dogs’ tails, make you crave sour and salty foods. Fact. (Except not really.)
8. One Ring to Bind Them…
When you’re not using your gold ring to enslave Middle Earth, you could possibly use it to determine the sex of your unborn child. Perhaps the most popular gender determination myth is that a gold ring suspended on a string over a pregnant woman’s belly will tell you what she’s carrying by how it swings: Side to side for a boy, circular for a girl. It’s not always accurate, of course, but will be right 50 percent of the time.
9. How you’re carrying
When I was pregnant with my son, we decided not to find out his gender; that occasioned a lot of people to inform me that they could tell whether I was harboring a blue or a pink based on how I was carrying. According to the very ancient lore, if you’re carrying a lower bump, it’s going to be a boy; if it’s higher, it’s a girl. According to the people who predicted my baby’s gender, he had a 50 percent chance of being a boy and 50 percent chance of being a girl, based on their scientific analysis. Thanks. How you’re carrying is not, scientists say now, a good indicator of your baby’s gender—it has more to do with your baby’s muscle tone, your personal shape, and even how old you are when you get pregnant.
