Many people want to know if a fetal heart rate over 170 is a boy or a girl? But is this guess the sex of the fetus accurate or not? Let's find out!
According to old beliefs, the baby boy's fetal heartbeat will be faster than that of girls. Therefore, based on the fetal heart rate will also guess whether your baby is a boy or a girl. Specifically:
Boy: The fetal heart will beat at an average rate of less than 140 beats / minute
Girl: The fetal heart will beat at an average rate of less than 160 beats / minute.
However, from a scientific point of view, there is not much difference between bisexual fetal heart rate. Numerous studies have found no correlation between fetal heart rate and fetal sex.
Many parents believe that based on fetal heart rate is able to determine the sex of the fetus.
The fetal heart will form around 6 weeks of pregnancy and change over the months. During an ultrasound you can see and measure the flashing lights on the ultrasound machine. The beats per minute (bpm) start at 90–110 beats / minute and increase each day. The fetal heart rate increases continuously until it peaks around 9 weeks. At this point the average heart rate will be between 140–170 bpm for boys and girls.
In fact, the above method is mainly based on folk experience. So according to experts, it does not guarantee scientific accuracy. D0 therefore, parents should not sex the fetus only through heart rate.
There have been many studies investigating the relationship between heart rate and sex. However, the results show that the heart rate does not indicate the sex of the fetus. This will not be a reliable indicator of the sex of the fetus.
One study examined 966 ultrasound results from women younger than 14 weeks of age. They repeat in the second trimester, when the fetus is between 18 weeks old and 24 weeks old. At this time, the sex of the fetus can also be determined by ultrasound . Only 477 women still met the study criteria. Of those, 244 cases were girls, while 233 were boys.
The American Journal of Obstetrics and Gynecology (2014) has published a remarkable result. Accordingly, the heart rate of boys and girls is only different during labor. A girl's heart rate will be slightly higher than that of a baby boy from the time the mother has colic until birth. Also no other time.
Only during labor, the heart rate between a girl and a boy has a difference.
Another 2016 study looked at the fetal heart rate of 332 girls and 323 boys. The study was carried out during the first 3 months of pregnancy. Researchers have also found no significant difference between them.
Instead of asking if a fetal heart rate over 170 is a boy or a girl, advanced scientific technology will give you the correct answer. Pregnant women can try one of the following methods:
This technique can be performed between the 18th and 20th weeks of pregnancy. In addition to determining the sex of the fetus, fetal ultrasound has many other benefits. Typical is the diagnosis of ectopic pregnancy or fetal risk of Down syndrome.
Pregnancy ultrasound is currently a popular way to determine the sex of the fetus.
This is also a small procedure to help determine the sex of the fetus. In addition, this technique can detect chromosomal abnormalities in the fetus.
This test will detect the presence or absence of the Y chromosome. From there, doctors will easily conclude that the fetus is male or female.
It is completely unscientific to predict the sex of the fetus by the fetal heart rate, namely that the fetal heart rate over 170 is male or female. Mothers should only see this as a form of reference to determine the sex of the baby. To know the exact results, after 20 weeks onwards mothers can go for an ultrasound. In addition, mothers can also try other scientific methods to find exact answers. Wish you have a healthy, safe and happy pregnancy.
