Today, most women use an ultrasound for baby gender prediction as this provides an accurate result when compared to other baby gender prediction methods (although nowhere as accurate as DNA testing). In addition, an obstetrician performs the operation making the test more reliable and safe. Apart from determining the baby’s sex, an ultrasound is also used to identify the heart rate pattern. 

According to old wives tales, the baby’s heart rate can also be a basis to identify the baby’s gender. Boys and girls have different heart rate patterns in the womb. This theory states that if the heart beat is lower than 140 beats per minute, the baby is going to be a boy. Alternatively, if the heart beat is higher than 140 BPM, then it’s a girl. Heart beats can be detected during the eight week checkup of pregnancy.

This baby heart rate theory still remains something of a myth in society. It could have been one of the easiest methods to determine the sex of a baby, if there was enough scientific evidence to support it. Its accuracy is still doubtful today, the reason being that heart rates increase or decrease on any day depending on the mother’s activity and how fast her own heart is beating. For these reasons, recording the heart beat pattern for one day cannot really determine the baby’s gender. However, a baby’s heart rate should not be discarded as an option because urban legends and common beliefs do also come true at times, and there is no harm in trying this kind of method.

There are a lot of prediction methods out there like: the drano gender test, the Chinese gender prediction chart and the wedding ring test which expectant mothers can try out. Even an ultrasound is not 100% accurate, but is necessary in checking the health of an unborn baby, having said all this, ultimately it is still the couple’s choice whether they choose to use the gender predicting method or wait for their big day
