Is the 20-week fetal heart rate accurate to see the sex of the fetus?

Generally speaking, when a fetus is separated from its mother, we can roughly distinguish between men and women according to the different shapes of its external genitalia. In addition, many people try to judge the fetal heart rate. So, is the 20-week fetal heart rate accurate to see the sex of the fetus?

Is it accurate to judge 20-week fetal heart rate according to fetal sex? Generally, the heart rate is around 140 beats/min when the prenatal examination is over 5 times, especially less than 140 beats/min, generally around 150 beats/min, especially more than 150 beats/min, especially in the third trimester (after 7 and a half months).

Why can't we judge the sex by the fetal heart rate once or twice? Because sometimes a female fetus just falls asleep after listening to the fetal heart rate, the fetal heart rate will be lower than that in her normal state, and sometimes a male fetus just moves in her mother's stomach when the doctor measures the fetal heart rate, so the fetal heart rate will be higher than that in his normal state, even exceeding 145 beats/minute. Therefore, it is necessary to have multiple fetal examination reports of expectant mothers to roughly judge gender.

Let's look at some data provided by netizens!

(1) I always knew 140, 19 days (a boy was born).

(2) The colleague's wife's fetal heart rate did not exceed 145 times and gave birth to a baby boy.

(3) At that time, my exam was always around 142, and then I gave birth to a boy.

(4) When I was pregnant with my son for 2 months, the fetal heart rate turned out to be 120, and the doctor said that I was asleep. At about 7 months, it was 136, and then 135. I think it's quite accurate.

(5) When I checked, the fetal heart rate was around 140 at first, and then it was generally around 145, which would not exceed 150, and a boy was born.

Boys and girls have long known that 1, the fetal movement on the right is a girl.

The tradition of male left and female right has always been respected, and many things are male left and female right. Fetal movement has a similar tradition. If the fetal movement is always on the right, it is likely to be a girl. If the fetal movement is more on the left, it is more likely to be a boy.

2, the belly is not the same.

During fetal movement, pregnant women will see large and small bumps on their stomachs, which is very interesting and a symbol of pregnant women. According to experience, we usually think that girls are big bags and boys are small bags.

3, fetal movement is a boy.

According to people's summary, boys have early fetal movement (boys are active) and girls have late fetal movement (girls are quiet). Usually pregnant women will feel fetal movement at 20 weeks. If they feel fetal movement (early fetal movement) a few weeks in advance, they may be pregnant with a boy.
