Why does the sex of the fetus flip the table ?

The gender of the fetus has always been a matter of great concern to expectant fathers and mothers, and many expectant mothers will imagine when they are just pregnant, whether the baby in the womb is a boy or a girl, so they will explore the gender of the fetus through various methods, and they will not stop until the goal is achieved. <>

But sometimes when I determine his gender, I find that the baby has turned over, which is not the same as I imagined.

Why does the sex of the fetus "flip the table"? 1.In fact, the most accurate way to identify whether he is a male or female treasure is a blood test and amniotic fluid test, but in our country, if it is not a medical need, this kind of thing cannot be done, so although it is very accurate, but generally speaking, we can't touch it, and there is no such thing as turning the tables.

2.In fact, the fetus can be distinguished from a male or female baby through the birth organ at about three and a half months of pregnancy, but if some inexperienced doctors see it, it is still possible to see it wrongly, and it can be seen clearly about four months of pregnancy. Some expectant fathers and mothers-to-be will learn about this result through various relationships.

It's just that although B ultrasound can directly see the fetus, it is not 100% accurate, otherwise how can there be so many reversals. In addition to the insufficient age of the fetus, there is also a reason that the posture of the fetus blocks the position that it wants to see, so it will not be clear to see, and sometimes it will be judged according to certain characteristics, and it will be found after the birth of the fetus, it turns out that it is wrong.

It's like a plot I saw on TV before, the family looked for an acquaintance to watch it with a B ultrasound, but it turned out that the fetus was facing away from the screen, and it couldn't be seen clearly at all. But a little bit grew in the middle of the thigh, so I thought it was a boy baby, and the point that grew out was the baby's little jj, and finally the baby was born as a baby girl, and it turned out that the little bit that grew out was just the navel belt.

Therefore, if you can't see clearly, a reversal will happen.

3.There are even some expectant fathers and mothers who judge whether the fetus is a boy or a girl purely based on folk methods.

For example, if a sour man is spicy and spicy, when she is pregnant, the expectant mother likes to eat sour and conceives a male treasure, on the contrary, if she likes to eat spicy food, she is pregnant with a female treasure.

It can also be judged according to the degree of pregnancy of the expectant mother, if the expectant mother is more pregnant, the belly is generally a female treasure, if not pregnant, it is generally a male baby.

Anyway, there are all kinds of methods, and even the palace clearing diagram is used, just to judge the baby's sex according to your own wishes. But we also said that this is just some folk methods, and there is no scientific basis, it is estimated that it is just a fun derived from the boredom of the ancients, how can it be taken seriously.

In the end, it's just a guess, since there is a 50% chance, there must be a possibility of a turnaround. <>

In the end, in fact, it is not the sex of the fetus that turns the pellet, but we have guessed wrong when we guess, and if we guess correctly, the fetus will not turn the pellet.

The early development of the fetus is not very complete, and some places may not be seen clearly through B-ultrasound, which is easy to cause misjudgment, and it may not be fully developed until the later stage. Therefore, it will lead to a later fetal reversal.

This should be a mistake in judgment, and when the child is not born, it is not 100% possible to determine what kind of gender it is by looking at the instrument, so it is normal to say that this reversal is very normal.

Generally speaking, the fetus baby in the mother's womb seven and a half months ago, will adjust its head position, if thick and turn into the head position is still in a breech position, it is called fetal breech position, then, breech fetal sex reversal, next, let's find out.

Fetal breech presentation is one of the most common abnormal fetal positions. Breech presentation before 30 weeks of gestation should not be considered abnormal; After 30 weeks, most of them can naturally turn into a cephalic position, and the persistent breech position accounts for about 3-4% of the total number of deliveries.

Breech delivery is more dangerous to the fetus, and it is prone to umbilical cord prolapse, fetal arm lifting, and difficulty in coming out of the back. Improper breech presentation can easily cause stillbirth, neonatal asphyxia, intracranial hemorrhage, birth trauma, etc. Perinatal mortality is 3 to 8 times higher than in the occipital anterior position.

The breech position takes the sacrum as the indication point, and is divided into six orientations: sacral left anterior, sacral left horizontal, sacral left posterior, sacral right anterior, sacral right transverse, and sacral right posterior. According to the type of presentation, it is divided into single breech position, complete breech position and incomplete breech position.

Breech presentation is the most common abnormal fetal position. The main causes of breech presentation are:

1. The fetus is too active in the uterine cavity, such as the abdominal wall of the mother is relaxed, the amniotic fluid is too large or the fetus is small, etc., so that the fetus moves too freely in the uterine cavity;

2. The fetus is limited in the uterine cavity, such as abdominal wall tension in primiparous mothers. Twins, oligohydramnios and uterine malformations, etc., affect the inability of the fetal head to turn down naturally;

3. Obstruction of the fetal head connection, such as pelvic stenosis, cephalopelvic disproportionality, placenta previa, obstruction of the soft birth canal and short umbilical cord, etc.;

4. Fetal malformations, such as hydrocephalus, anencephaly, etc., are not easy to connect with the fetal head into the pelvis. Most of these causes can be detected and properly dealt with in a timely manner through ** and B-ultrasound examinations.

Breech presentation before 30 weeks of gestation should not be considered abnormal; After 30 weeks, most of them can naturally turn into a cephalic position, and the persistent breech position accounts for about 3-4% of the total number of deliveries. Breech delivery is more dangerous to the fetus, with umbilical cord prolapse, fetal arm lifting, and difficulty in coming out of the posterior. Improper management of breech presentation can cause stillbirth, neonatal asphyxia, intracranial hemorrhage, birth trauma and other bench postures, and the maternal mortality rate is 3 8 times higher than that of the occipital anterior position.

The breech position takes the sacrum as the indication point, and is divided into six orientations: sacral left anterior, sacral left horizontal, sacral left posterior, sacral right anterior, sacral right transverse, and sacral right posterior. According to the type of presentation, it can be divided into single breech position (also known as straight leg breech presentation), complete breech position (also known as mixed breech presentation or compound breech presentation) and incomplete breech presentation.

So, what are the causes of fetal breech position?

Pelvic stenosis, birth canal tumors, abdominal wall laxity, multiple births, polyhydramnios, fetal malformations, etc. are the main causes of breech presentation.

1. The uterine cavity is wide, there is more amniotic fluid, the abdominal wall of multiparous women is excessively relaxed, and the fetus is frequently active in the uterus, which is easy to cause breech position.

2. Uterine malformation, small uterine cavity, limited fetal movement in uterus, resulting in the fetal head can not turn downward, easy to become breech.

Zhiyuan 3, placenta previa, pelvic stenosis and pelvic tumor obstruction of the pelvic cavity all affect the fetal head to descend into the pelvis, and it is easy to become breech.

4. There is little amniotic fluid, and the fetal legs cannot be flexed and straightened, which affects the flexion or rotation of the fetus, and it is easy to become a breech.

When you go to bed at night, don't tighten your legs, and don't eat too quickly when eating, and at the same time, eat less hot things like durian.

Pregnant mothers have something to cover when doing B ultrasound examination, medical staff do not see clearly, and folk judgment of the sex of the fetus will lead to the gender of the fetus "turning over", in fact, boys and girls are the same, pregnant mothers keep a normal mind, as long as the baby is healthy and happy.

In life, there will be old people or some friends based on past experience, to judge the sex of the fetus, and even some people will directly spend money to go through the back door to let the doctor tell but, everything is not absolute, even if it is a scientific method to identify the sex of the fetus with b ultrasound, sometimes there will be, oolong, situation, there is a fetal sex, turn the tables, originally prepared for boys or girls A lot of things, then it will not be useful. Some will also have some shocks.

I don't know if everyone is like me, there will always be some strange dreams after pregnancy, many of them are about the gender of the child in the womb, the so-called day thinking, night dreaming, should be related to my usual daytime curiosity about the baby, very curious about whether the baby is "China Merchants Bank" or a "construction bank", from time to time I will think about whether it is like myself or like my husband?

Although it is rare for our generation of young parents to have the idea of "preference for sons", when you have a son, you will have the heart to look forward to your daughter! Make a pair of "good".

Then there are many "home remedies" about judging the gender of the child at home, such as according to the walking form of the pregnant mother, the shape of the pregnant belly during pregnancy, dietary preferences, etc., even if the pregnant woman who is not superstitious at all sees it, she can't help but "sit down" by herself!

That is, the ambush makes it known that it is not credible, but it will still be "entertained". But in fact, medicine also has a way to distinguish between men and women during pregnancy, that is, B ultrasound, but there are cases in our country that clearly prohibit all forms of identification of the sex of the fetus in various forms except for medical needs. However, it is not guaranteed to be 100% accurate, because the world is impermanent, and you should have more or less heard of the "reversal" of fetal sex!

Through the introduction of the following points, let everyone thoroughly understand the mystery implied in the gender "reversal"!

1. The sex of the fetus controlled by time.

The determination of the sex of the fetus is about 16 weeks later, to make it clear, after the combination of the fertilized egg in the body is completed, the sex of the fetus has been finalized, and it is generally not changed by other factors, so in the pregnancy test B ultrasound before 16 weeks, the fetal sex will be checked, which is actually very inaccurate, because there are infinite changes in the development of the fetus's sexual organs during this period, and it is easy to have large errors.

In fact, in the four-dimensional stage, it is possible to know the sex of the fetus, but it will also be judged by the fetus not cooperating with the examination and judging the mistakes of the waiter, but everyone must strictly know that it is not allowed to identify the sex of the fetus! Remember!

Two: according to the reaction of the pregnant woman.

Each pregnant mother's preference during pregnancy is different, it may be influenced by the idea of "sour and spicy girls" before pregnancy, deliberately catering to the taste of "want to eat" during pregnancy, and it is also possible that it is also affected by the taste of pre-pregnancy diet. It is also not surprising that the shape of the pregnant belly is judged by the shape of the pregnant belly, and that the belly of a boy is pointed and the belly of a girl is round.

Each pregnant mother's physique and personal living habits are very different, and the development of the fetus is not affected by the pregnant mother, so each pregnant mother will have different reactions can be reasonably explained.

Don't be too entangled in the question of whether it is a man or a woman, the answer will always be revealed after the baby is born, parents should look forward to the baby, whether it is a princess or a prince, should get the love of parents, peace and security, health and health is what we should pay attention to!
