Can the heart beat rate predict gender?

A fun part of the pregnancy is to find out the baby gender other than choosing a baby name. We are thrilled to have either boy or girl. Their genders are already determined at the conception and we are not gonna lose sleep on it. 

MYTH: If the fetal heart rate is below 140 beats per minute, it's a boy; if it's above 140, it's a girl.

Is it true? Sooner or later, we will find out.

"Studies, however, show no significant difference between a male and a female heart rate, at least statistically speaking. The normal heart rate for a fetus is anywhere from 120 to 160 beats per minute. The heart rate will fluctuate from beat to beat and demonstrates what is called fetal heart rate variability. The developing fetal brain is controlled by the sympathetic nervous system (the fight-or-flight response) and the parasympathetic (relaxation) system. As the brain develops, these two systems engage in a power struggle. The heart rate speeds up when stimulated by the sympathetic system and slows down when controlled by the parasympathetic response. So, depending on the arousal of the fetus, the heart rate can be 130 on one day, 110 the next, and 150 the next. We usually listen to the fetal heart rate for about ten to thirty seconds at a time. If the baby is awake and moving, the heart rate may be higher than if it is sleeping.

We can extrapolate this theory. Men and women, boys and girls do not have different heart rates based on gender. The heart rate in a healthy individual is a response to external stimuli and not necessarily caused by the gender of the individual."

Some other myths include:

1. Ever heard the saying that a girl can steal your beauty? They say that if you have breakouts, then chances are you’re having a girl.
2. If you’ve been spared bouts of nausea, maybe it’s a boy.
3. If Daddy has more brothers than sisters, chances are his y-sperm is stronger which increases the possibility of having a boy.
4. Craving salty foods could mean you’ve got a little man on the way.
