The jingle about boys and girls is 100% accurate in testing boys and girls
Human reproduction is something that everyone is concerned about. Many people want to know whether they will have a boy or a girl in the future. However, in ancient times, there was no very effective testing method. With the development of modern science and technology, there are many scientific methods to predict the gender of pregnant women\’s babies. Below we will introduce these methods in detail.
Gender gene
Human gender is determined by the X and Y chromosomes. Among the X and Y chromosomes, the X chromosome is the common chromosome and is common in women; while the Y chromosome is the chromosome in men. Before fertilization, the egg contains only the X chromosome, while the sperm may contain both X and Y chromosomes. Therefore, male sperm can determine the gender of the baby. When the Y chromosome in the sperm meets and combines with the egg, a boy is born. If the X chromosome in the sperm meets and combines with the egg, a girl will be born.
To predict the gender of the baby, we can use a blood test to send a sample of the mother\’s blood to a hospital laboratory for observation. The immune test method can detect the DNA of the sex chromosome in the mother\’s serum to determine the sex of the baby.
Fetal heart rate
Fetal heart rate is also an effective way to predict your baby\’s gender. In the 9-14 weeks (early) stage of a woman\’s pregnancy, some scientists have discovered that if the fetal heart rate exceeds 140 beats per minute, it may be a boy. If the baby\’s heart rate is less than 140 beats per minute, it\’s probably a girl.
However, this prediction method is not completely accurate because the fetal heart rate is affected by many factors such as fetal age, maternal position, fetal activity, perinatal period, and fetal health status. Therefore, we cannot rely solely on fetal heart rate to predict the gender of the baby.
Pregnant woman’s weight
A pregnant woman\’s weight is also a factor in predicting the sex of her baby. If you gain less weight later in your pregnancy, you may have a girl. If a pregnant woman gains weight very quickly in late pregnancy, she may have a boy.
However, this method is not reliable either. Because every pregnant woman\’s weight gain is different during pregnancy, some pregnant women may have difficulty controlling their eating habits, which may lead to very rapid weight gain.
Prenatal B-ultrasound
Modern medicine uses B-ultrasound technology in prenatal examinations to detect and record babies. One of the factors that affects gender is that if the baby\’s urethra rises at a large angle, it is likely to be a boy. If your baby\’s urethra rises at a smaller angle, it\’s most likely a girl.
Normally, doctors will record the gender of the baby during the B-ultrasound. However, it should be noted that this method still has errors when the baby is still relatively young.
Summary
Through different scientific methods such as genetic testing, fetal heart rate, maternal weight and prenatal B-ultrasound, we can get preliminary results of the baby\’s gender and judge the accuracy of the results. However, when making gender prediction, it is necessary to considerTaking into account many uncertainties, not all forecast results are accurate. If you want to draw a more accurate conclusion, it is recommended to go to the hospital for a real examination.
