My wife is more than seven months old and has a fetal heart rate of 140, is it a boy or a girl??

The speed of the fetal heart rate is completely independent of whether the boy or the girl is fast. You can take your wife for a scan, I believe you can see it at this stage.

But why care if it's a man or a woman, as long as the wife and children are safe and sound.

Whether it's male or female has nothing to do with heart rate.

Do you really want to know how to go overshoot and raise your heart rate?

It doesn't matter what it does, besides, what does it matter if it's a man or a woman?

So, call your child out and I'll ask.

Is the fetal heart rate around 140 a boy or a girlThere is no relationship between the number of fetal heartbeats and the sex of the fetus, so the fetal heart rate of about 140 cannot be used to determine the sex of the fetus.

According to the folk saying, if the fetus has a heart rate of less than 140 beats, it is a boy; More than 140 points are girls.

In fact, the heart rate of girls is higher than that of boys, and this is true only at birth, and there is no difference in the heart rate of the fetus between boys and girls. The speed of the heart rate only varies with gestational age. At about 5 weeks of gestation, the baby's heart rate is close to the mother's heart rate, i.e. 80-85 beats.

Then, by 9 weeks of pregnancy, the heart rate gradually increased to 170-200 beats. It then slows down to 120-160 bhs in the second trimester.

Therefore, it is unscientific to rely on the fetal rate to distinguish the birth of boys and girls, but if you have nothing to do, you can also use this method to entertain it, which is harmless and can entertain the body and mind, but it is not excessive, the birth of a boy and a girl is predestined, and it cannot be forced, as long as it is your own, both men and women are the same.

What is the fetal heart rateFetal heart rate is how often the fetal heart beats.

The fetal heart rate is regulated by the sympathetic and parasympathetic nerves, and the monitoring pattern formed by the signal tracing of the instantaneous fetal heart rate changes can be used to understand the response of the fetal heart rate during fetal movements and contractions, so as to infer whether the fetus has hypoxia in the uterus.

Normal fetal heartbeat:The normal fetal heart rate is 120 160 beats, and the rhythm is neat, the strength is moderate, like the "ticking" sound of a clock. The fetal heart rate can increase by 10 to 20 beats when the fetus moves.

If it is consistently higher than 160 minutes or less than 110 minutes, it is an anomaly.

Abnormal fetal heartbeat:At first, the fetal heart rate increases compensatorily, and the fetal heart rate rises markedly above 160 beats, but the heart sounds decrease. If the cause of the disease is not resolved in time, the fetal heartbeat will slow down, below 110 points, the heart sound will be weaker, or even disappear - the fetus dies.

How to know the sex of the fetus1. Ultrasound scanning.

When using ultrasound to diagnose the sex of the fetus, the accuracy of the fetus can reach more than 95% for the male baby and only about 85% for the female baby.

2. Amniocentesis.

In order to diagnose whether the fetus has chromosomal or neural tube defects, it is usually performed at 16 to 20 weeks of pregnancy, and the sex of the fetus can also be known, with an accuracy of 99%, but there is a 1% chance of miscarriage.

3. Chorionic villus collection.

In order to diagnose whether the chromosomal normality of the fetus is or not, but there are also people who use it to diagnose the sex of the fetus, the accuracy rate can reach 98%, yes but it can cause miscarriage by 3% to 5%, usually done at 8-10 weeks of pregnancy.

4. Blood test. Using genetic engineering technology, the mother's blood is taken to determine the sex of the fetus, and there is no danger to the fetus, and the general pregnancy period is 8 weeks.
