The previous child can predict the male and female of the next child.

The previous child can predict the male and female of the next child. Having a child is an important issue before everyone. In fact, for the first child It is also the one that receives the most attention. There are many opinions on whether to give birth to a boy or a girl in our lives. The following is a prediction of whether the next child will be male or female. The previous child predicts whether the next child will be male or female 1

1. The number of lines on the inner thigh of the first child is determined. If the first child is a girl, there is only one line on her inner thigh, which means that the second child will give birth to a boy. , if there are two lines, it means giving birth to a female baby.

2. Look at the hair whorl. A straight hair twist means the birth of a female baby for the second child, and a crooked hair spiral means the second child has a male baby.

3. Based on the facial features, if the eldest child looks more like a boy when he is born, then the second child will be a boy. If he looks like a female, then the second child will be a girl.

The months to give birth to a girl in 2022

If you get pregnant in October, November, and December of 2022, you will be born in August to September of 2022 It is easier to give birth to a daughter. The temperature of the environment where men and women live one month before sexual intercourse will affect the gender of the baby at birth. Low temperature environment will affect the activity of the Y chromosome of sperm, which is conducive to giving birth to a girl.

Is it more likely to give birth to a girl if the pregnancy line fades at nine months of pregnancy?

The main reason why the pregnancy line fades has nothing to do with the pregnant woman’s diet and whether she will give birth to a girl. It's just a normal physiological reaction. In fact, the probability of having a boy or girl is the same, so there is no need to guess the gender of the baby. The previous child predicts whether the next child will be male or female 2

There is a secret to giving birth to a boy or a girl

Chromosomes

Why do some people want a boy but choose a girl? Why do some people need to give birth to a girl? A girl is born but a boy happens to be born. What is going on in this birth of a boy and a girl? There have been various speculations about this since ancient times, but they are all without scientific basis.

It was not until the early 20th century that scientists discovered the chromosomes in human cells, and then the mystery of gender was revealed. It turns out that a boy or girl is determined by a pair of sex chromosomes in a fertilized egg.

Every cell in the human body (including reproductive cells) has 23 pairs of chromosomes that carry genetic material. 22 pairs of chromosomes are autosomes. All the genes contained in the 23 pairs of chromosomes are genetic information, and the other 1 The pair of sex chromosomes determine the sex of the fetus. The types of trait genes contained on autosomes are the same for both men and women, and there is no gender difference.

The sex chromosomes are different. The male pair of sex chromosomes is composed of X chromosome and Y chromosome (the male chromosome composition is 22+XY), and the female pair of sex chromosomes are both X chromosomes (the female chromosomes The composition is 22+XX). Half of the 23 pairs of chromosomes come from the father and the other half from the mother.

Human cells reproduce through meiosis, that is, one cell divides into 2, and then 2 divides into 4, and continues to divide in this way. During the development of immature germ cells into mature germ cells, the chromosomes in the cells undergo two divisions. The last one is meiosis. That is, the mature sperm or egg cell only contains 23 chromosomes, half of the original number. , 22 of which are autosomes and 1 is a sex chromosome.

One pair of male sex chromosomes is XY, so after mature sperm division, one type containing X sex chromosomes is called X sperm, and the other type containing Y sex chromosomes is called Y sperm. One pair of female sex chromosomes is XX, so the mature eggs contain one X sex chromosome. It can be seen that there are 2 types of male sperm and only 1 type of female egg. Therefore, the birth of a boy or a girl depends on the type of male sperm cells.

Fertilized egg

After the sperm and egg combine, they merge into one and become a fertilized egg. In this way, the 23 chromosomes in the sperm and the 23 chromosomes in the egg are paired into 23 pairs of chromosomes. If an X sperm combines with an egg, the pair of sex chromosomes in the fertilized egg will be XX, and the fetus will develop into a female; if a Y sperm combines with the egg, the pair of sex chromosomes in the fertilized egg will be XY, and the fetus will develop into a male. It can be seen that whether a boy or a girl is born depends on whether the sex chromosome carried by the man's sperm is X or Y, and has nothing to do with the egg.

The gender of a child is determined at the moment of fertilization, and both parties account for half of the determining factors. The previous child can predict whether the next child will be male or female 3

Scientific method to determine the gender of the fetus

1. Ultrasound scan: Ultrasound is a type of sound wave. Reports so far show that it has a positive effect on the fetus. It has no adverse effects and is therefore very commonly used in the obstetrics and gynecology community. When using ultrasound to diagnose the gender of the fetus, the accuracy for baby boys can reach more than 95%, while the reliability for baby girls is only about 85%. Moreover, the accuracy is directly related to the experience of the B-ultrasound technician or doctor.

2. Amniocentesis: Amniocentesis is mainly used to diagnose whether the fetus has chromosomal or neural tube defects. It is usually performed between 16 and 20 weeks of pregnancy. Since the chromosomes of the fetus can be known, the gender of the fetus can also be known. The accuracy is 99%, but there is a 1% chance of miscarriage.

Therefore, the medical community does not agree with performing amniocentesis or drawing umbilical cord blood just to predict the gender of the fetus.

3. Chorionic villus sampling: Also known as "chorionic villus sampling", it is usually done between 11 and 14 weeks of pregnancy. The main purpose is the same as amniocentesis, which is to diagnose whether the fetal chromosomes are normal, but some people also use it to diagnose the gender of the fetus. The accuracy rate can reach 98%. Although chorionic villus sampling can determine the gender of the fetus at 11 weeks of pregnancy, it may cause miscarriage (3% to 5%), and may also harm the fetus, causing its hands and feet to be mutilated. Therefore, it is best not to undergo this test just to determine the gender of the fetus.

4. DNA blood test: Genetic engineering technology can be used to determine the gender of the fetus by taking maternal blood. It can be done after 8 weeks of pregnancy, and it will not have any impact on the pregnant woman or the fetus. This technology is very mature both abroad and in Hong Kong. It is currently the earliest, fastest and safest way to identify the gender of the fetus. Because sampling is simple and convenient, has no impact on the mother and fetus, and has high accuracy, reaching 99.5%, it has become a hot topic among modern people.

34. Hanging The pencil method to determine the gender of the fetus (find a pencil with an eraser on one end, use a threaded needle to pierce the end of the eraser, so that you can lift the pencil by the thread, point the pen tip vertically downward, and then point the pen tip towards you vein of the wrist), the pen tip makes a longitudinal movement (that is, the swing direction of the pen tip is consistent with the direction of the arm), it is a male, and the pen tip makes a transverse motion (that is, the pen tip swings in a direction perpendicular to the arm, it is a woman), and the pen tip makes a circular motion, indicating Not pregnant (you can use your husband as a test);
