Is It a Boy or Girl? 15 Old Wives' Tales vs What Science Says

Boy or Girl? 15 Old Wives' Tales Put to the Test (Plus What Actually Works)
Long before ultrasounds existed, expectant families relied on folklore, intuition, and creative tests to predict their baby's gender. While we now have medical science to tell us for certain, these old wives' tales remain a beloved part of pregnancy traditions—and a fun way to engage guests at gender reveal parties!
Let's examine 15 popular gender prediction myths, see what science actually says about each, and discover how to turn them into entertaining party activities.
Why We Love Gender Prediction Games
Gender prediction games have endured for centuries because they tap into our natural curiosity and desire for connection. They're:
- •Fun and engaging - Everyone loves to guess!
- •Conversation starters - Great for baby showers and reveals
- •Family bonding - Grandparents often share stories of predictions from their pregnancies
- •Harmless entertainment - No pressure, just fun
The Old Wives' Tales: What They Claim vs. Reality
1. The Ring Test
The ring's movement is caused by tiny involuntary movements in your hand (ideomotor effect)—the same phenomenon behind Ouija boards and dowsing rods. The baby's sex has no influence.
2. Carrying High vs. Low
How you "carry" is determined by:
- •Your muscle tone and body type
- •The baby's position
- •Whether this is your first pregnancy
- •Your core strength
None of these relate to the baby's sex.
3. Food Cravings (Sweet vs. Salty)
Studies show no consistent pattern between cravings and baby's sex. Cravings are more likely influenced by:
- •Nutritional needs
- •Hormonal changes (not gender-specific)
- •Cultural food preferences
- •Individual metabolism
4. Morning Sickness Severity
A few studies have found a slight correlation between severe morning sickness and female babies. One Swedish study found women hospitalized for hyperemesis were slightly more likely to have girls (56% vs. 44%). However, this is far from reliable for prediction.
5. Baby's Heart Rate
Multiple studies have found no significant difference in fetal heart rates between boys and girls. Heart rate varies based on:
- •Gestational age
- •Baby's activity level
- •Time of measurement
- •Baby's health
A 2006 study of over 10,000 pregnancies found no correlation.
6. Chinese Gender Calendar
Studies have tested this calendar against actual birth records and found accuracy rates of 50%—exactly what you'd expect from random chance. The "ancient" origins are also disputed.
7. Skin Changes (Acne = Girl)
Pregnancy acne is caused by increased hormones—from YOUR body, not the baby's. Hormone fluctuations affect everyone differently regardless of baby's sex.
8. Mayan Gender Predictor
This is essentially a coin flip dressed up as ancient wisdom. No biological mechanism could connect these numbers to sex determination.
9. Mother's Intuition
Interestingly, some studies show mothers guess correctly slightly more than 50% of the time—around 55-70% in some research. However, this could be influenced by:
- •Confirmation bias
- •Cultural expectations
- •Dreams
- •Subtle physical cues
Not reliable enough for certainty, but not entirely random either!
10. Hair Growth
Pregnancy hormones affect hair growth differently for everyone. Some women experience faster growth, some slower, some thicker hair—regardless of baby's sex.
11. Baking Soda Test
The fizzing reaction depends on the acidity of your urine, which is influenced by:
- •How much water you've drunk
- •What you've eaten
- •Time of day
- •Kidney function
None of this relates to baby's sex.
12. Garlic Test
How your body processes garlic depends on your own metabolism, gut bacteria, and sweat glands—not your baby's sex.
13. Key Test
How you pick up a key depends on the key's position, your hand dominance, and random chance. Zero biological connection.
14. Breast Size Changes
One Polish study found a slight correlation between larger right breast and male babies, but the study was small and hasn't been replicated. Most doctors consider this unreliable.
15. Dad's Weight Gain
Couvade syndrome (sympathetic pregnancy symptoms in fathers) happens with both boys and girls equally. Dad's weight gain relates to lifestyle changes, stress eating, or eating what mom craves—not baby's sex.
What ACTUALLY Predicts Baby's Gender?
If old wives' tales are unreliable, what actually works?
Medical Methods (Actually Accurate)
| Method | Accuracy | When Available |
|---|---|---|
| NIPT Blood Test | 99%+ | 10+ weeks |
| Ultrasound | 95-99% | 18-22 weeks |
| Amniocentesis | 99.9% | 15-20 weeks |
| CVS | 99.9% | 10-13 weeks |
Timeline Summary
- •10 weeks: NIPT blood test available
- •14-16 weeks: Some skilled ultrasound techs can guess
- •18-22 weeks: Anatomy scan (most common way to find out)
- •Birth: 100% accurate (obviously!)
Never rely on old wives' tales for any important decisions. They're entertainment only! For accurate gender determination, consult your healthcare provider.
