My friend told me that the gender of the unborn baby can be predicted by observing its heart rates. If the baby’s heart rate is 140 beats per minute (bpm) and above, it is likely to be a girl. Is it true?
The heart rate of the baby starts out at about 80-85bpm around the 5th week of pregnancy. It increases rapidly, reaching a peak of 170-200 bpm by the 9th week. It gradually decreases and becomes stable between 120 - 160 bpm from the15th week till delivery at term. One cannot predict the gender of the unborn baby from its heart rates. A study in1980 measured the fetal heart rate of 10,000 babies. It found no correlation between the baby's heart rate at any point throughout pregnancy and the gender .This was confirmed subsequently by another study in 2006.
