Boys are born prematurely, girls drag their months! Is there a scientific basis for this mother baby

In fact, for babies born earlier or later than the due date, this is not determined by the mood of the baby, but by the development of the lungs of the fetus, generally speaking, the same month of male and female treasures, male treasures than female treasures lung development is a little faster, so the male babies have mature lungs, they will be born early, and the baby girl is not in a hurry, take your time, and wait for the lungs to develop perfectly, and then start! Therefore, there is still some truth in saying that boys are born prematurely and girls are lazy, but it is not 100%, and the development of each fetus is different.

There is no scientific basis for this statement, but the older generation believes that male babies are born before the due date, and most female babies are past the due date.

Personally, I don't think there is a scientific basis for this saying. The timing of childbirth depends on the child's own development and the physical condition of the mother, and there is no necessary connection with the birth of a boy or a girl.

In fact, the due date is only an approximate time, and it is normal for the fetus to be born about two weeks before and after the due date. Of course, although there is no scientific basis for the saying "boys are born prematurely, girls are lazy", there is a certain probability, which is why this saying has been widely circulated for so long. In that case, how can a boy be "born prematurely", and how can a girl be "lazy"?

Some pregnant mothers have weak physical fitness, and the digestion and absorption of nutrients are not enough, and the nutrients that can be given to the baby will not be enough, which can easily lead to the lack of nutrients in the baby and affect the development, which will obviously lead to premature birth. On the other hand, some pregnant mothers digest and absorb well, and the food expenses during pregnancy are also very rich and <>

The baby can be given excellent development conditions, the functional standards of the pregnant mother itself will be better, and the baby will be "unwilling to leave the mother's belly too early". Although folk customs have always been popular in many ways to identify the sex of the baby, which uterine clearance surgery gives birth to male and female tables, which PH pH, which abdomen looks, and which B ultrasound singles, but they are just some "experience sharing" by everyone, and there is no basis in medicine. We know that the purpose of a baby's fetal sex is to be determined by chromosomes.

The chromosome composition of the boy is xy, and the chromosome composition of the female baby is xx.

The sex chromosomes of the baby depend on the sperm and egg at the moment of union, in other words, the sex of the baby's fetus depends at that moment, and it has nothing to do with the shape of the baby and the shape of the belly. In terms of the regularity of fetal growth and development, there is no view in medical books that boys develop rapidly and little girls develop slowly. The uniform regularity is 37 weeks of term, and after 37 weeks, the fetus will start to mature on its own.

Generally speaking, the fetus grows and develops earlier during pregnancy before the ovulation date, and it is very easy to be born before the due date. If you conceive after the date of ovulation, the fetus grows and develops later, and it is very easy to be born after the due date.

The rate of fetal growth and development is the key factor in determining whether the expected date of delivery will be earlier or later. Exercise status during pregnancy. If you exercise regularly during pregnancy, the fetus will enter the plate earlier.

Special circumstances. If there is a collision or other unexpected element in the later stages of pregnancy, it will cause the due date to be early. As the so-called melon ripens and falls, the fetus matures and the embryo continues to age, and the fetus will release the pregnant woman's delivery data signal to the pregnant mother into the pregnant woman's delivery.

The reasons for endangering the perfection of the fetus have nothing to do with the sex of the fetus, only the health status of the pregnant mother during pregnancy and the supply of nutrients are correlated.

There is no basis for affecting the growth of the fetus and the pregnant woman is directly related, the surrounding environment, mood and diet, these have a key role.

There is no scientific basis, and it is related to the birth and safety of the fetus, and it is related to the development of the child.

There is no scientific basis, and it is related to the birth of the baby and the physical condition, and the development of the child.

There is a delicate relationship between the time of having a child and the sex of the child!

The date of birth of a fetus is affected by a variety of factors, but in comparison, the results of the study show that the baby is born earlier than the baby.

In terms of medicine, it is believed that the prenatal development of the fetus varies depending on the sex of the fetus. Under the different effects of male estrogen, male babies may develop relatively faster, and if male babies reach birth standards early, they are prone to be born earlier than their due date. Is it true that "boys are born early, girls are delayed"?

On the contrary, there is no scientific basis for the practice of "judging the sex of the fetus by the time of birth", and the sex of the fetus cannot be accurately determined by experience or experience alone. Eventually, there are many cases where births are made earlier than the due date.

Is the due date accurate?

I don't know much about the expected date of delivery in life, and think that the due date refers to a specific day, but in fact it refers to a time range, and the medical side believes that it is normal to give birth within two weeks before and after the expected date of delivery, and the time range is still relatively large, whether the child can be born within the due date can be judged by a combination of various factors. Some fetuses mature early, and the birth conditions are naturally born earlier than the expected date of delivery, and some fetuses are in a stable state of development, and the pregnant woman has to be in the womb a little longer to meet the birth conditions, and the birth time is also postponed accordingly.

In addition to factors related to the development of the fetus itself, the physical condition of the pregnant woman also affects the date of birth of the fetus. For example, some pregnant women with related diseases are more likely to be born prematurely if the pregnancy environment is affected in poor physical condition. Some pregnant women are in good physical condition and have a stable menstrual cycle, and such pregnant women are closer to the pre-judgment of delivery.

In fact, the due date is correct or not, and it is all compared. If it is classified according to the general perception that the correct date is used, the due date is very small, so most pregnant women cannot have children. However, from a medical point of view, according to the definition of the expected date of delivery, the due date is divided based on the time frame, and the due date is relatively accurate, and most pregnant women can have a child within that time frame.

What should I pay attention to when I am approaching my due date?

This means that production can happen at any time as the due date approaches. To cope better, pregnant women must prepare in advance. Clothing, diapers, milk powder and other related supplies should be prepared in advance.

Not very necessary, but be sure to bring. Understanding the knowledge of pregnant women is to relieve the pressure of women's childbirth and adjust their mentality. Paying attention to physical changes, such as water rupture, bleeding, pain relief, etc., is a more obvious prenatal reaction, and once this happens, there is nothing wrong with receiving ** in time.

In order to maintain her physical condition, the pregnant woman must perform proper exercises during the labor stage, improve her physical strength, and improve her physical strength, which helps in childbirth.

Birth and morning have a certain relationship with the sex of the child, but this cannot be used as a means to determine the gender of the child. The exact date on which the child will be born is affected by a variety of factors, but if the pregnant woman remains healthy and the fetus is developing normally, she can be born within the due date.

I don't think there is any scientific basis, it depends on the individual's physical problem, some boys will also procrastinate, this situation is different from person to person!

There is no scientific basis for the statement that premature girls drag on the month, this is just quietly related to the usual exercise and physical fitness of pregnant women.

There is no basis for this claim, it is just some folk rumors, which is not very credible.

After pregnancy, the hormone level in the pregnant mother's body will change greatly, and some studies say that the hormone level in the pregnant mother's body will also be different depending on the sex of the baby. Studies believe that if a pregnant mother is pregnant with a boy, the hormone secretion in the body will make the fetus grow faster, so the fetus can mature earlier, and they will be born earlier.

There is not enough scientific evidence for this statement, it is just a study, and it cannot be used as a scientific basis, so pregnant mothers should not believe it.

The development of the fetus is determined when the fetus becomes a fertilized eggIf it is possible to tell that it is a boy or a girl from the length of pregnancy, it is obviously inaccurate most of the time, because there are also many girls who are born prematurely, and many boys who are procrastinated. In fact, most of the time, the old man's words are just to comfort the pregnant mother, and the baby in the belly is not a big deal, and saying the difference between boys and girls is just to divert the attention of the pregnant mother.

Boys are born prematurely, girls are procrastinated" is more like a psychological comfort for expectant fathers and mothers-to-be, in fact, as long as the fetus is born healthy and healthy, gender is really not that important, you say, right?

Male babies develop faster in their mother's womb than female babies due to the difference in male and female hormone levels, male babies develop faster in their mother's womb than female babies when the babies have the same birth weightWhen a boy is born, the mother's gestation is usually shorter than that of the girl's mother.

The baby's birth weight is also one of the important measures of the baby's development level in utero, and in full-term babies, male babies tend to weigh more than female babies.

Fetal maturation is the most important factor affecting the time of birth of the fetus. The sooner the fetus matures, the sooner it will start. Conversely, the later the fetus matures, the later it will start.

My big baby's pregnancy week is one week older, so around 39 weeks pregnant, the baby will start.

Therefore,The early or late birth of the fetus is related to the development of the fetus and the pregnancy of the pregnant womanIt is not that the initiator is affected by the sex of the fetus. Boys are born prematurely and girls are procrastinated, in fact, it is just a coincidence.

ConclusionGenerally speaking, we believe that a mature fetus is considered after 37 weeks, and delivery after 37 weeks is considered a normal full-term birth. As long as it is not more than 42 weeks, after 42 weeks, it is considered an overdue pregnancy, and it needs to be "promoted".

Therefore, boys will not necessarily be born earlier than the due date, and girls may not be born after the due date, just let it be, as long as the full moon is full, the melon is ripe, when the baby wants to come out, we will give birth to when we want.

No, because it is up to the man to give birth to a boy or a girl, preterm birth is decided by a pregnant woman, and preterm birth and confinement have nothing to do with having a boy or a girl.

There is no state model, this is just a false argument obtained by people based on experience, this sentence has no scientific basis, this is just an experience that people say, and the credibility is not very high.

The sex of the fetus is determined when it becomes a fertilized egg, and if it can be judged from the length of pregnancy, it is obviously inaccurate most of the time, because there are also many girls who are born prematurely, and many boys who are prolonged. In fact, most of the time, the old man's sentence is just to comfort the pregnant mother, the baby in the belly is not a big deal, and the difference between boys and girls is only to divert the attention of the pregnant mother.

Boys are born prematurely, and girls drag the moon" is more like a psychological comfort for expectant fathers and mothers-to-be, in fact, as long as the fetus is born healthy and healthy, gender is really not that important

This sentence is not based on any science, the child is born early and late, or the month is delayed, it is closely related to the body of the pregnant mother Naichun mother, not that the boy will be born prematurely, and the girl will be wide and procrastinated.

"Early birth of a precious child" is actually just a word we use to congratulate others, such as a husband and wife who are newly married, we will bless and say that they have a precious son early.

However, "early birth" does not mean that boys will be born prematurely, it originally means to bless others to have children as soon as possible.

As for the statement that boys are born prematurely and girls are lazy, there is no scientific basis, and it is not scientific, so pregnant women do not need to believe it too much.

The mother of the second child informed: As the saying goes, "premature birth" boys are born prematurely, and girls are lazy, is there really a scientific basis?

As the saying goes, "premature birth", boys are born prematurely and girls are lazy, and there is no scientific basis for this.

The birth of a boy or a girl has nothing to do with the "early birth of a precious child", and there is no such thing as a boy being born prematurely and a girl being lazy.

The normal time of pregnancy and delivery, regardless of whether it is a boy or a girl, is expected to be at 40 weeks of pregnancy, and the birth time of the fetus is not earlier than 37 weeks of pregnancy.

A fetus born earlier than 37 weeks of gestation is a premature baby, and premature babies do not mean that only boys are born prematurely, but girls are also born prematurely in the case of abnormal pregnancies.

As far as the time of birth of the fetus is concerned, it is normal to give birth within two weeks before and after the expected date of delivery. In other words, whether it is a postponement of the due date or an early delivery of the due date, as long as it is within two weeks before and after the 40th week of pregnancy, it is a normal situation.

And whether it is a boy or a girl, it is possible to advance or postpone. There is no certain early due date for boys and late due date for girls.

Therefore, there is no scientific basis for boys to be "born prematurely" and girls to be lazy for months. There is no credibility in judging that boys are born early and girls are born later.

The time of birth of the fetus is gender-independent, so it can be born earlier or later in both boys and girls

Generally speaking, the birth time of the fetus (boys and girls) is not earlier than 37 weeks, because the fetal development earlier than 37 weeks is not yet mature, especially the lungs are not yet mature, and they cannot establish a good respiratory system after birth. In addition, if all aspects are immature, the body will be relatively weak, and the survival rate will be relatively low.

Therefore, 37 weeks of pregnancy is a dividing line, and both boys and girls born earlier than 37 weeks are considered premature babies. There is no gender requirement for premature babies.

After the fetus is full-term, generally speaking, after 38 weeks of gestation, the ideal time for delivery is to give birth. Because the expected date of delivery of the fetus is 40 weeks of pregnancy, and the medical regulations stipulate that the fetus born within two weeks before and after the expected date of delivery is normal.

Therefore, under normal circumstances, the birth time of the fetus is between 38 and 42 weeks, and 40 weeks is the midpoint. Therefore, regardless of whether the fetus is a boy or a girl, the normal time of birth is at this stage.

Therefore, because of the saying "early birth of a precious child", there is no scientific basis for a boy to give birth to a girl prematurely, so there is no need to believe it too much.
