Baby Heart Rate Gender: Myths, Science, and What It Really Means
Many parents wonder if a baby’s heart rate can reveal gender, but science shows it’s mostly a myth. While old wives’ tales suggest that fetal heart rates above 140 bpm indicate a girl and below 140 bpm a boy, research on thousands of pregnancies proves there’s no significant difference between boys and girls. Heart rate in neonates normal ranges from 100–180 bpm at birth, influenced by age, activity, and sleep, not gender. Terms like sinusoidal fetal heart rate are medical indicators of fetal health, not sex.
