Can You Guess Your Baby's Sex?
Trying to tell whether it's a boy or girl? Here's what works -- and what doesn't.
Pregnancy Myth #4: The Drano Test continued...
Reality: Mass doesn't know of any medical reason why a Drano-urine mixture could predict a baby's sex. "There's no change in the acidity or alkalinity of a boy or girl chromosome," she says.
The few studies that have been done on the subject also refute the claim. In the early 1980s, researchers at the University of Wyoming performed the test on 100 pregnant women and found it to be "roughly equivalent to flipping a coin" for predicting gender. A 1999 Canadian study yielded similar results.
Even if the technique did work, Drano is a caustic chemical -- not something you want to be playing around with or breathing in while you're pregnant, Beard says.
Pregnancy Myth #5: Sweet Tooth
Myth: A pregnant woman who craves sweets is having a boy. If she craves sour foods, she's having a girl.
Reality: Your baby boy might grow up to have a sweet tooth, but while he's in your womb he's not going to make you desperate for an ice cream cone or candy bar. If you're craving sweets (or any other food), it's probably because your shifting hormones have intensified your sense of smell.
Pregnancy Myth #6: Sick to Your Stomach
Myth: If you have morning sickness all day, it's a girl.
Reality: This myth might have some truth to it. Studies have found that women with a severe form of morning sickness called hyperemesis gravidarum are more likely to give birth to girls.
The reason? Levels of the pregnancy hormone hCG, which triggers morning sickness, tend to be higher in mothers who are pregnant with female babies.
But a pregnant woman can certainly have morning sickness, even bad morning sickness, when she's carrying a boy. So no, you can't count on it being a girl if you've got serious morning sickness.
Pregnancy Myth #7: Look at the Calendar
Myth: The Chinese Lunar Calendar can predict a baby's gender based on the mother's age when she conceived, and the month of conception.
Reality: The Chinese Lunar Calendar was discovered in a 700-year-old Royal tomb, and many pregnant women who've used it swear by it. Could this ancient artifact have some modern science behind it? Not necessarily. According to the same Canadian researchers who did the Drano test, the Lunar Calendar is no more accurate at predicting a baby's gender (50/50) than a random guess.
