2022 – Can you guess the gender of your baby?

If you’re pregnant, you’ll likely hear things like this – sometimes from complete strangers: “You’re low on pregnancy. They must have had a boy,” or, “If you’ve been feeling sick all day, it’s definitely a girl.”

There are even more outlandish myths about predicting the gender of a child. Someone suggests hanging a wedding ring from a lock of the father’s hair on her stomach. Another suggests mixing urine with Drano. Color is said to be an indicator of your baby’s gender.

Now that medical technology has made it possible to determine the sex of a fetus with near absolute certainty, why are these old stories still true?

The internet and social media are at least partially responsible for the ongoing pregnancy rumor mill. Legends fly through cyberspace, moving from one location to another at warp speed.

People reading these random comments may mistake them for medical facts. “Sometimes people place a higher value on what is said online than what their doctor says,” says Sharon Maas, MD, an obstetrician-gynecologist in Morristown, NJ, and clinical assistant professor at the University of Medicine and Dentistry of New Jersey.

Believe it or not

While most wives’ stories of guessing the baby’s gender are harmless, “My medical warning to my patients is: Please make sure you know the source of what you’re paying attention to or what you’re sharing,” says Maas.

New parents — especially those who are pregnant for the first time — can be especially vulnerable to pregnancy rumors, says Eileen Bird, senior practice counselor at the American College of Nurse Midwives. “You are so interested in doing the right thing and having all the information. I think it makes you vulnerable in some way. Even people who don’t usually believe in superstitions are more likely to do that.”

Another reason there are myths about sexual predictions is that sometimes they can seem true. If you look at 50/50 odds, predictions come true half the time. Surprisingly, at least some of these methods have evidence to support them.

Here’s what the experts have to say about some of the most prevalent rumors about baby gender prediction.

Myth #1: Baby’s Gender Prediction: Low Pregnancy

myth: If your belly is low (or forward), then you have a boy. If it’s high (or wide in the middle), you get a girl.

Indeed: This is pure legend. “How you hold yourself is simply about the tone of your muscles and the position of the baby,” Beard says. These factors, along with your body shape and pregnancy weight gain – not the baby’s gender – determine how low or high your belly will be.

Myth #2: The rhythm of the heart

myth: If a baby’s heart beats faster than 140 beats per minute, it’s a girl.

Indeed: This is a myth her patients ask about on a daily basis, and there may be little truth to it in reality.

A 2006 study showed no gender differences in fetal heart rate during the first trimester of pregnancy, but Maas says that’s not surprising given that babies’ hearts generally beat faster in the first 28-30 weeks of pregnancy. The difference becomes apparent later in pregnancy. A 1999 study showed that a fetus’s heart beats faster than a fetus’s heart just before birth. Maas says she sees a similar trend in her patients.

Myth #3: Episode Test

myth: Hang your wedding ring on a lock of your father’s hair on your stomach. If the ring swings in a circle, then it is a girl. If you rock back and forth, that’s a boy. An alternative version of this myth recommends dangling a needle on the mother’s wrist.

Indeed: There is no real evidence to confirm or deny this. Maas doesn’t see any scientific basis for this, but says that people who follow TCM can interpret the dangling ring (or pin) as evidence of the body’s natural forces.

Myth #4: The Drano Test

myth: Stir some Drano into the urine. If the mixture turns green, it’s a boy. Other color changes have been suggested for this legend, but green is the most common.

Indeed: The mass does not know any medical reason why the urine mixture predicts the sex of the baby. “There is no change in the acidity or alkalinity of a boy’s or girl’s chromosome,” she says.

The few studies conducted on the subject refute this claim. In the early 1980s, researchers from the University of Wyoming performed the test on 100 pregnant women and found that it was “roughly equivalent to tossing a coin” in predicting gender. A Canadian study from 1999 reached similar conclusions.

Even if the technique works, drano is a caustic chemical — not something you want to mess with or inhale during pregnancy, says Bird.

Myth 5 Predicting the Gender of a Baby: Sweet Tooth

myth: A pregnant woman craving sweets gives birth to a boy. If they crave sour food, they get a girl.

Indeed: Your baby may grow up to have a sweet tooth, but as long as he’s in your tummy he won’t leave you craving an ice cream cone or a candy bar. If you’re craving sweets (or other foods), it’s probably because hormonal shifts have heightened your sense of smell.

Myth #6: Stomach sickness

myth: If you’ve been struggling with morning sickness all day, girl.

Indeed: There may be some truth in this legend. 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, which causes morning sickness, tend to be higher in mothers who are pregnant with girls.

But any pregnant woman can experience morning sickness, even severe morning sickness when pregnant. So no, you can’t count on her being a girl if you have severe morning sickness.

Myth #7: Look at the calendar

myth: The Chinese lunar calendar can predict the gender of the baby based on the mother’s age at conception and the month of conception.

Indeed: The Chinese lunar calendar was discovered in a 700-year-old royal tomb and many pregnant women who used it swear by it. Could there be modern science behind this ancient artifact? not necessarily. According to the same Canadian researchers who conducted the Drano test, the lunar calendar is no more accurate than a random guess in predicting the gender of a child (50/50).

How do you really know

If you are curious about your baby’s gender, you can have an ultrasound, which is usually done between weeks 18 and 20 of your pregnancy. Assuming the ultrasound technician has a good view between your baby’s legs, the imaging procedure should be able to tell you the baby’s gender with 80% to 90% accuracy.

Amniocentesis and chorionic villus sampling can also determine the sex of your baby with great accuracy, but these more invasive tests are usually reserved for cases where the baby may have a genetic disorder or a chromosomal abnormality, such as Down syndrome.

In addition, the genetic tests provided by doctors’ clinics after the ninth week of pregnancy examine the sex chromosomes and verify the sex of the child with an accuracy of 99%.
