The fetal heart rate of a boy is about 140 and that of a girl is about 150

Can the gender of the fetus be determined based on the fetal heartbeat? This is a question that many parents and elderly people want to know the answer to, but this is actually not reliable, because there are many factors that affect the fetal heartbeat, which are not necessarily related to the identification of the fetal gender. But many people are still curious about whether a fetal heartbeat of 150 means it is a boy. So let’s discuss: Is a fetal heartbeat of 150 a boy or a girl? If the fetal heart rate is 150, is it a boy or a girl?

If the fetal heart rate is 150, is it a boy or a girl?

Many friends hope to get an accurate answer to this question, but unfortunately, there is still no scientific evidence to prove the accuracy of fetal heart rate monitoring in detecting the gender of a baby. However, many relevant experts still emphasize that the claim of using fetal heart rate monitoring to determine the gender of a baby has no scientific basis, and people should not blindly believe in it. The function of fetal heart rate monitoring is not to detect the gender of the baby. Its content is to record the monitoring graph curve generated by the instantaneous changes of the fetal heartbeat based on the data signal, and to grasp the response of the fetal heartbeat when the baby moves and the uterus contracts, in order to infer whether the baby in the uterus is hypoxic. The normal fetal heart rate range is 120-160 beats/minute. Therefore, the heart rate baseline below 140 is a boy, and above 140 is a girl. This statement is unreliable. In addition, the condition of the pregnant woman herself also affects the changes in the fetal heartbeat. For example, if the pregnant woman has a fever, the fetal heartbeat will often exceed 160 beats/minute; if the pregnant woman has a relatively hyperactive thyroid hormone, her own heartbeat will be rapid, and the fetal heartbeat will also often exceed 160 beats/minute. Therefore, expectant parents are reminded not to be too obsessed with the method of fetal heart rate monitoring to determine the gender of the baby. There is a folk saying that if the fetal heart rate is less than 140 beats/minute, the baby is a boy. Generally speaking, girls have a higher heart rate than boys, but this has nothing to do with determining the sex of the fetus. The normal heart rate of the fetus is between 120 beats/minute and 160 beats/minute. Experts emphasize that listening to the fetal heart rate requires the use of professional instruments. Doppler auscultation can be used to hear the fetal heartbeat in a very quiet environment around 12 weeks of pregnancy. We recommend that pregnant mothers go to the hospital to listen to it, or use a fetal talker at home. The fetal talker app also has a gender test function.

Fetal heart rate 150 means it's a boy

There is a saying that if the fetal heart rate is less 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 between the heart rate of boys and girls in the fetus. The heart rate only changes with the gestational age. At about 5 weeks of pregnancy, the fetus' heartbeat is close to that of the parents, which is 80-85 beats per minute. Then until the 9th week of pregnancy, the heart rate slowly increases to 170-200 beats/minute. Then, during the middle of pregnancy, it slowly slows down to 120-160 beats per minute. In fact, it is unreasonable to determine the gender of the baby based on the fetal heart rate. The fetal heart rate refers to the monitoring graph generated by the fetal heart rate regulated by the central nervous system and sympathetic nervous system. It records the changes in the fetal heartbeat in an instant through data signals. It can grasp the response of the fetal heartbeat when the baby moves and the uterus contracts, so as to infer whether the fetus in the uterus is suffering from lack of oxygen. The normal fetal heart rate is 120 to 160 beats per minute. If the fetal heart rate is above 160 beats per minute or only 100 beats per minute, it is abnormal, indicating that the fetus may be suffering from intrauterine hypoxia and should be treated promptly. As for the high fetal heart rate, it is only a matter of probability to say that the fetus is a girl. The speed of the fetal heart rate cannot be used to determine the gender of the fetus.
