Is the fetal heart rate accurate for boys and girls?

Several pregnant female colleagues were chatting in front of a B-ultrasound sheet. They kept saying, "The fetal heart rate is less than 140, it must be a boy!" Xiaoli longed for a boy. A smile spread across his face.

I thought to myself, Xiaoli, don’t believe this. What if everything comes to nothing? Just have fun with it, don't take it seriously.

Since the pregnancy, speculation about boys and girls has not stopped. There are many rumors circulating, none of which have scientific basis. The fetal heart rate is the same for men and women, which is unscientific. Popular saying

Regarding the fetal heart rate of boys and girls, the popular saying is as follows:

If the fetal heart rate is about 140 beats/min, the fetal heartbeat is fast and not strong enough, it is a girl. .

The fetal heart rate is less than 140 beats/min, the fetal heart beat is slow and very strong, it is a boy.

In the hospital, I heard that the fetal heartbeats of babies are so rhythmic and powerful, but they are both boys and girls.

I was also obsessed with this statement, and mistakenly thought that my second child was a girl, but it turned out that the actual situation was exactly the opposite, that he was a boy. What is fetal heart rate and what is the normal value?

Fetal heart rate is an indicator to evaluate whether the fetal body is normal. It can be used to predict the development of the fetus in the womb, whether there is hypoxia, etc., and has nothing to do with gender.

The basic heart rate standard for scientific research is 120-160 beats/minute, and does not differentiate between boys and girls. Therefore, it is incorrect and unscientific to say that the lower the fetal heart rate, the greater the chance of being a boy. .

Fetal heart rate is a dynamic data. The data detected each time only represents the situation at the time of detection, and will not always be high or low. The fetal heart rate is different when the fetus is sleeping or moving. Therefore, there is no difference between men and women.

The speed of fetal heart rate is related to the fetus itself and the body of the pregnant mother. If there is insufficient intrauterine oxygen and the pregnant mother is anemic, the fetal heart rate will be faster.

The normal fetal heart rate range is 120-160 beats/min. As long as it is within this range, it is healthy. If it is too high or too low, there may be hypoxia problems. How many beats per minute is the boy's fetal heart rate?

I found Dabao's maternal health care manual and looked at it. The fetal heart rate was basically concentrated around 146 beats, which was greater than 140 beats/min.

The fetal heart rate of my second child is as follows: the fetal heart rate detector detects data between 140-156 beats/min. The fetal heart rate detected by B-ultrasound was between 139-158 beats/min. Only one of the 6 B-ultrasounds was 139 beats/min, and the rest were all above 150 beats/min. In short, the second baby's fetal heart rate is greater than 140 beats/minute.

Judging from the situation of the two male babies in my family, it shows that the popular belief that fetal heart rate determines whether the baby is male or female is unreliable.

The fetal heart rate shared by friends is as follows:

Friend 1: The symptoms of my pregnancy with my son: The fetal heart rate was 140-150 throughout the pregnancy.

Friend 2: This is not accurate. I am now six months old and my fetal heart rate has always been between 130-150. I have found out that it is a girl.

Friend 3: I am giving birth to a baby. Yes, the heart rate is above 150. For a girl, the second child has a heart rate of 130 to 140 each time. The gender is not yet known. It will be announced in a month.

Friend 4: My second daughter is one month old, and the fetal heart rate in previous pregnancy tests was 120 to 130.

Friend 5: When I was pregnant with my son, the highest was 145, and since then it has not been higher than 140.

Friend 6: Mine is around 150, male, and the fetal heart rate is not accurate.

Friend 7: My daughter, between 146-138

Friend 8: Our basic fetal heart rate has always been 160, and the baby is a boy

Friend 9: Basically Both are above 150, and the boys are boys

Friend 10: The eldest boy is between 130 and 140.

Friend 11: My second baby is not allowed to be between 136 and 154, the boy. The eldest child is almost the same as a girl

Friend 12: They said it depends on the baby after 36 weeks. I am more than 130 after 36 weeks, and the baby is a boy

Friend 13: Mine It is around 156

Some babies happen to cater to this view, but most of them go against it, and there is no relevant scientific literature to prove the reliability of this statement.

Looking at boys and girls is indeed the most curious thing for mothers, but guessing is okay, but don’t take it seriously. Many rumors that have been circulated have been denied. Even B-ultrasound shows that men and women turn into women.

What is your baby’s fetal heart rate? Is it consistent with the popular saying? Let’s chat together.
