What is the fetal heart rate when pregnant with a boy?

Pregnancy is the happiest stage for women, and being pregnant with a boy or a girl is a key factor affecting the future development of a family. Therefore, most people are very concerned about whether the baby is a boy or a girl. According to my country's national conditions, most people like to be pregnant with a boy, and it is difficult to distinguish whether the baby is a boy or a girl. However, there are clues. For example, some people believe that listening to the fetal heart rate can distinguish whether the baby is a boy or a girl. Let's take a look at what the fetal heart rate is when the baby is pregnant with a boy.

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/minute.

Girls have a higher heart rate than boys, but this is only true when they are born. When they are still fetuses, there is no difference in the heart rate of male and female fetuses.

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.

Pregnant mothers can actually feel changes when listening to the fetal heart rate. However, the speed of heart rate only varies with gestational age. Generally speaking, at 5 weeks of pregnancy, the fetus' heart rate is close to the mother's heart rate, which is 80 to 85 beats per minute. Then, during the 9th week of pregnancy, the heart rate gradually increases to 170-200 beats per minute. In the second trimester, the heart rate gradually slows down to 120-160 beats per minute.

Therefore, it is basically unreliable to use fetal heart rate to determine the sex of the fetus! However, pregnant mothers should still pay more attention to the fetal heart rate, because although it cannot determine whether the baby is a boy or a girl, it can reflect the development of the fetus!
