How many fetal heart rates indicate a girl?

During pregnancy, some parents will especially want to know the gender of the fetus, and then they will look for various identification methods. There are many such methods among the people. For example, many people will judge the gender based on the fetal position. In addition, judging the gender by the fetal heart rate is also something many people often do. Here I would like to make it clear to everyone that no matter how fast the fetal heart rate is, there is no scientific basis for judging the gender by this method, so it is best not to believe it.

How many fetal heart rates indicate a girl?

After a woman has been pregnant for a certain period of time, she can hear the fetal heartbeat. The number of fetal heart beats per minute is called the fetal heart rate. It is best for modern women to learn how to monitor fetal heart rate, so that they can detect abnormalities in fetal heart rate in time, which is very helpful in ensuring the healthy development of the baby. So how many heartbeats does the fetus have to have to be a boy during pregnancy?

1. How much is the fetal heart rate for a boy?

There is a saying that if the fetal heart rate is lower than 140 beats/minute, it is a boy; if it is higher than 140 beats/minute, it is a girl.

The truth: Girls have a higher heart rate than boys, but this is only true when they are just born. There is no difference in the fetal heart rate between boys and girls.

The speed of heart rate only varies with gestational age. At about 5 weeks of pregnancy, the fetus' heart rate is close to the mother's heart rate, which is 80-85 beats/minute. Then during the 9th week of pregnancy, the heart rate gradually increases to 170-200 beats/minute. Then during the second trimester it gradually slows down to 120-160 beats per minute.

2. Does a high fetal heart rate mean it is a girl?

In fact, it is unscientific to judge the gender of a baby by the fetal heart rate. The fetal heart rate refers to the fetal heart rate regulated by the sympathetic and parasympathetic nerves. By recording the instantaneous changes in the fetal heart rate through the signal, the curve of the monitoring graph can be used to understand the reaction of the fetal heart during fetal movement and uterine contraction, so as to infer whether the fetus in the uterus is suffering from hypoxia. The normal fetal heart rate is 120 to 160 beats per minute. If the fetal heart rate is above 160 beats per minute or lasts for 100 beats per minute, it indicates intrauterine fetal hypoxia and should be treated promptly. As for the statement that "a high fetal heart rate means a girl" is just a matter of probability, the sex of the fetus cannot be determined from the speed of the fetal heart rate.

3. Is it accurate to determine the gender of the fetus based on the fetal heart rate?

Is fetal heart rate accurate in determining gender? Gynecologists point out that this actually has no scientific basis. Because the content of fetal heart monitoring examination is the curve of the monitoring graph formed by signal tracing the instantaneous changes of fetal heart rate, it is possible to understand the reaction of the fetal heart rate during fetal movement and uterine contraction, so as to infer whether the fetus in the uterus is suffering from hypoxia. The normal fetal heart rate is between 120 beats/minute and 160 beats/minute. If the fetal heart rate remains <120/minute or >160/minute for more than 10 minutes, it indicates that the fetal heart rate is abnormal.

The condition of the pregnant woman herself also affects the changes in the fetal heart rate. For example, if the pregnant woman has a fever, the fetal heart rate will often exceed 160 beats/minute. If the pregnant woman has hyperthyroidism, her own heart rate is very fast and the fetal heart rate will often exceed 160 beats/minute. If the pregnant woman takes certain medications, it can cause the mother and child's heart rate to accelerate. A slow fetal heart rate may be caused by fetal hypoxia, but sometimes pregnant women take certain medications that act on the fetus through the placenta, causing the fetal heart rate to slow down.

This article introduces how to determine whether a pregnant woman is carrying a boy or a girl by using the fetal heart rate. From the introduction in this article, you can know that the fetal heart rate has nothing to do with whether the baby is a boy or a girl. Pregnant women can monitor their fetal movements and detect fetal abnormalities, but they cannot determine whether it is a boy or a girl based on the fetal heart rate.
