Is the fetal heart rate of 130 a boy or a girl?

If the test result is a fetal heart rate of 130, this is within the normal range, so pregnant mothers can rest assured. This is also a manifestation of the stability of the fetal life characteristics. In real life, people will use many methods to determine the gender of the fetus, such as judging by the fetal heart rate. In the eyes of many people, a faster fetal heart rate is a girl, and a slower fetal heart rate is a boy. So is there any scientific basis for this judgment?

Is the fetal heart rate of 130 a boy or a girl?

The fetal heart rate is the heartbeat of the fetus. During pregnancy, many pregnant women are particularly fond of monitoring their fetal heart rate and listening to the baby's heartbeat. Many women hope to determine whether they are pregnant with a boy or a girl by the frequency of the fetal heart rate. So is this method of judging whether it is a boy or a girl accurate? Is the fetal heart rate of 130 a boy or a girl?

The normal heart rate of the fetus is between 120-160 beats per minute. Experts point out that special instruments are needed to listen to the fetal heart rate. The fetal heart rate can be heard in a very quiet environment with a Doppler stethoscope around 12 weeks of pregnancy, but if an obstetric stethoscope is used, it cannot be heard until 18 weeks of pregnancy.

There is a folk saying that if the fetal heart rate is less than 140 beats per minute, it means a boy is born; if the fetal heart rate is at least 140 beats per minute, it means a girl is born.

However, it is not reliable to use the baby's fetal heart rate to determine the baby's gender. For adults, men's heart rate is generally lower than women's. However, the heart rate of baby girls is higher than that of baby boys, but this is only the case when they are just born. When they are still fetuses, there is no difference in the heart rate of male and female fetuses.

The speed of the fetal 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/minute.

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 signals, we can understand the reaction of the fetal heart rate during fetal movement and uterine contraction, and infer whether the fetus in the uterus is suffering from hypoxia. The normal fetal heart rate is 120-160 beats per minute. If the fetal heart rate is above 160 beats per minute or lasts for 100 beats per minute, it indicates fetal intrauterine 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.

Therefore, judging the gender of the baby by the fetal heart rate is not necessarily accurate. Even if it is accurate, it is only a low-probability event. Therefore, mothers should not worry too much about whether the baby's heartbeat is high or low, as long as the baby is healthy.

Through the introduction in this article, we can know that the fetal heart rate of 130 cannot actually determine whether the baby is a boy or a girl. If you are a pregnant woman who wants to know whether you are pregnant with a boy or a girl, there are many scientific methods you can use. But it is worth noting that China does not allow the identification of fetal gender, and probably no doctor will tell you.
