How to know whether it is a boy or a girl?
Having a boy or girl is a matter of great concern to many parents. The development of science and technology has also provided people with more and more effective ways to predict the gender of their baby. This article will introduce in detail how to scientifically and effectively predict the gender of the baby from four aspects: genes, pregnancy symptoms, ultrasound examination and other methods.
Genes determine male and female
Genes are one of the main factors that determine a person\’s gender. Under normal circumstances, humans have a genome composed of 23 pairs of chromosomes. The 23rd pair of chromosomes is divided into two types, X and Y. Women have two X chromosomes, while men There are X and Y chromosomes respectively. Therefore, if the father\’s sperm carries a Y chromosome, then the fertilized egg will have an XY chromosome combination, and the baby will be a boy; if it carries an X chromosome, the fertilized egg will have an XX chromosome combination, and the baby will be a girl.
Of course, this is only a theoretical way of determining sex, and it is not limited to this situation, because sometimes chromosomal genes will mutate, resulting in other gender characteristics.
Tips on pregnancy symptoms
During pregnancy, changes in the mother\’s body will also have a certain prompting effect on the gender of the baby. Depending on individual physiological differences, some pregnant women may have different manifestations of certain special symptoms during pregnancy, leading people to guess the gender of their baby.
For example, facial acne, cold hands and feet, excessive fetal movement, and high uterus during pregnancy are often considered signs of having a boy; while stretch marks, morning sickness, and heavy breath during pregnancy are considered signs of having a girl. However, these symptoms have no solid scientific basis and should not be relied upon.
High accuracy of ultrasonic examination
Ultrasound examination is a more scientific and accurate way to predict the gender of the baby. After 12 weeks of pregnancy, B-ultrasound can be used to check the gender of the fetus, which is used to determine the period for prenatal diagnosis after 20 weeks. B-ultrasound technology is widely used in prenatal screening and early diagnosis because of its simplicity, safety and accuracy.
Warm reminder: Due to the movement and position changes of the fetus during growth, there may be some situations that are difficult to diagnose. For example, the gender of the fetus cannot be determined at this time. At this time, you can strengthen your health management during pregnancy and wait for a more accurate examination period.
Other methods and references
In addition to the above methods, there are many other methods known as superstitions. For example, using baby powder, hanging hair with needles, etc. are all somewhat speculative. But in fact, these so-called methods have no scientific basis, so they can be used as a reference. Of course, if you like these methods, while they can be used as family fun, the results shouldn\’t be taken too seriously.
Summary
From the aspects of genes, pregnancy symptoms, ultrasound examination and other methods, there are many scientific and effective ways to know whether it is a boy or a girl, but it is not advisable to use superstition. Therefore, we are welcome to try more mysterious methods in our traditional culture and experience, but when pursuing the true gender, we should rely on formal medical examinations and scientific research, so as to avoid bringing consequences to you and your baby.Any unnecessary risks.
