Pregnancy is surrounded by countless old wives’ tales and myths about predicting your baby’s gender. While these myths make for fun party games, understanding the scientific facts helps keep expectations grounded.
Here is the truth behind 5 famous gender prediction myths:
Myth 1: Fetal Heart Rate Predicts Gender
- The Myth: A heart rate over 140 bpm means a girl; under 140 bpm means a boy.
- The Fact: Clinical studies published in obstetrics journals show that fetal heart rates vary naturally between 120 and 160 bpm for both boys and girls.
Myth 2: Belly Shape Indicates Fetal Sex
- The Myth: Carrying “high and round” means a girl; carrying “low and wide” means a boy.
- The Fact: Bump shape is determined by maternal abdominal tone, height, pelvic structure, and fetal posture.
Myth 3: Sweet Cravings Mean Girl, Salty Cravings Mean Boy
- The Myth: Craving sugar means a girl; craving salty snacks means a boy.
- The Fact: Food cravings during pregnancy are caused by hormonal fluctuations and nutritional needs, not fetal sex chromosomes.
Myth 4: Morning Sickness Intensity Determines Sex
- The Myth: Severe morning sickness means you are having a girl.
- The Fact: While extreme hyperemesis gravidarum has a slight statistical correlation with higher HCG levels in female pregnancies, standard morning sickness occurs equally across sexes.
Myth 5: Traditional Prediction Charts Are 90% Accurate
- The Myth: Chinese or Mayan charts can accurately predict gender with over 90% accuracy.
- The Fact: Large-scale population studies (including a study of 2.8 million Swedish births) proved that folk charts have an accuracy rate of 50.2%—identical to a random coin flip.
