Is there a method for determining the sex of the child by the date of conception, which works at 100%, and what you should believe?

At all times, women wanted to know what child they bear. And best of all is to be able to "order" the floor. This is especially true for those who are already raising children of the same sex and really wants a toddler of the opposite sex. It is in such situations that the feverish search for methods and methods for fitting crumbs with the floor begins.

The “knowledgeable” Internet is ready to provide many different ways to determine the sex of a child by the date of conception, according to some properties and characteristics of the blood of the parents, and even according to the mysterious methods of Freiman-Dobrotin and Budiansky. How do these techniques work, are there any 100% reliable among them, what to believe - we will answer these questions in the framework of this article, consider all known methods and analyze the results.

To better understand the essence of different methods, as well as to understand whether they are effective, you need to understand how the formation of the sex of the baby. Even from school biology lessons in high school we all know that two sex gamete cells — male (sperm cell) and female (egg cell) — take part in the conception of a new man. Each of these cells has its own genetic set. A sperm cell may have a set of XY and XX. A female egg always carries only set XX.

If the sex of the future baby depended only on a woman, as some claim, only individuals with a set of XX would be born, that is, only girls. No options. But nature acted on the side of diversity and gave the right to bear responsibility for the sex of the offspring to men. If a female egg fertilizes sperm with a set of twentieth, a girl is born. If fertilization takes place with the participation of the male sex cell with the XY set, a boy is born. There is no other.

Gender can not change, because the genetically set, brought by sperm, is not subject to any effects. Maternal and paternal chromosomes merge to form a new organism. And from the first minutes after conception, every little thing is determined: at the genetic level, it is obvious what the eye color of a child, the color of his skin and hair, height and build, what will be inherited diseases and even character traits, talents and abilities will be.

The sex glands in the embryo are formed from 5-6 weeks of gestation. Mom still wonders if she is pregnant, does the tests and rejoices in the stripes, and the baby is already beginning to develop prototypes of the glands, which later become the ovaries in girls or the testicles in boys. There are no external differences in the fruit - boys and girls have a small genital tubercle where later the external genitals will be formed. This happens until about the 12th week of pregnancy.Then the bodies only grow and grow in size, opening up possibilities for diagnosis by ultrasound.

But until the middle of pregnancy, expectant mother is often unbearable. Paul wants to know before, and sometimes even before conception. Therefore, a lot of questions arise, many myths are born around gender determination at the earliest possible time or when planning. This behavior is not peculiar to modern women, their distant ancestors also sought by any means to find out the sex of the heir. Some had to give birth to a boy, a successor to a dynasty, a throne, or for religious reasons. Others dreamed about their daughter and tried their best to learn how to conceive her.

In their attempts, the women drank the blood of sacrificial animals, went to the seers and sorcerers, wondered about the stars and omens, ate special food and drank decoctions of herbs. They are forgivable, because at that time they still did not know that what was drunk and eaten by a woman can in no way affect the genetic set of the male reproductive cell. Today, women, although knowledgeable in medicine, have an education, continue to insistently demand an effective method to determine the sex of the child. Let's look at the methods that are commonly used for this.

The way is based on the assumption that human blood can be updated and does it at certain intervals. It is assumed that in the representatives of the stronger sex this occurs once every three years, and in women once every four years. The authors of the method, whose names have not gone down in history, argue that it is possible to conceive a girl when the mother’s blood has been refreshed last, that is, is younger than her partner’s. To conceive a boy, according to the method, the opposite condition must be met - the father’s blood must be more “young”.

In fact, the method is a great way to develop logic and thinking. Training the brain will give mathematical calculations, because in order to understand whose blood is "younger", you have to carefully calculate.

You can start from birth. Men divide age by 4, and women by 3. But it's not that simple. Too much to consider. Thus, an operation, even a small one, blood transfusion, donation, large blood loss during injuries or injuries virtually "nullify" all the blood renewal cycles that were before, and everything starts from scratch.

It works like this. If a woman is 24 years old, and her man is 28 years old and none of the partners became a donor, could not tolerate blood transfusions and did not do operations, 24 should be divided by 3 and 28 by 4. We get the number of updates from a woman - 8 , a man - 7. The last update occurred in a man, and therefore a high probability of having a boy.

Now let's imagine that a woman underwent surgery a year before pregnancy. Her blood at the same number 8 will be younger, and, according to the methodology, more likely to give birth to a daughter. If, three years before conception, a man fell on the operating table, then the chances of having a boy will grow again.

We evaluated the effectiveness of the method from reviews on the Internet, since there was a good deal on the forums that “it came together — it didn't work out”. For the most part, opinions are divided. The estimated accuracy of the gender prediction method for blood renewal is no higher than 50-55%. With the same success, nothing can be considered and not to do ultrasound. Any pregnant woman has a 50% chance of giving birth to either a boy or a girl. Third, as they say, is not given.

What does traditional medicine think about the method? Nothing at all.The theory of blood renewal is not reflected in the scientific works on medicine, it actually does not exist. What the authors of the method had in mind when speaking of the “update” is also not entirely clear to doctors. There is such a thing as "hemopoiesis", but it can be considered rather conditional as an update. Hemopoiesis refers to the formation of blood cells by the bone marrow with the participation of the lymphatic system. This process is daily, continuous, if it occurs once every few years, a person would not have survived. No other renewal of blood undergoes every three years, or every four years.

In addition, hemopoiesis proceeds in exactly the same way and people of different gender and age, which gives the right to argue that it is in no way associated with reproduction: the blood is updated every minute from any person - an infant, a teenager, an old man. While the person is alive, hemopoiesis is present. Therefore, the method of updating blood to the category of exact we can not be attributed.

For some reason, the authors of this methodology also wished to remain unknown. But a stunning theory was left to the suffering, the essence of which boils down to the fact that the blood type of the parents directly affects the sex of the unborn child. So, it is assumed that a woman with the first group of blood and her partner with the same group usually give birth to girls. If the owner of the first blood group wants to have a son, she will have to find a partner with the second blood group.

Almost the same picture with the Rh factor. The authors of the method are confident that the Rh-negative woman can count on the birth of a daughter only from a Rh-positive man.

What these conclusions are based on is not explained. But from myself I would like to say that the author of this article has the first blood group with a similar group with a partner. It would seem that she should live in a flower garden of girls, but three guys grow up in a family. One puncture can be considered an accident, but three in a row is unlikely. In addition, the theory can not explain how to understand the birth of the same pair of children of different sexes.

Traditional medicine about this method is not excluded, and does not suspect. No medical textbook or nurse reference book describes the quality of sperm or eggs in connection with a blood group. In men with the first and second groups, with the third and fourth, and also with both variants of Rh-accessories, there is an approximately equal ratio of sperm with the genetic set XX and XY in the seminal fluid. Therefore, the chances of conceiving girls and boys are about equal.

The group and rhesus of a woman are important only for the well-being of carrying a fetus (with a negative Rh factor in the expectant mother, the development of an immune conflict with the erythrocytes of the fetus conceived from a Rh-positive man is not excluded). Neither the group and the rhesus can affect the reproductive abilities of the woman, nor the sex of the child.

The moment of conception was emphasized at all times. Astrologers and numerologists believe that from this moment the natal chart of a future member of society begins. By the date of conception, they determined the destined fate, and also sought to understand whether it was a boy or a girl. There are several methods based on the day of conception, all of them are quite popular among women. Let's look at them in more detail.

Science does not know for certain where and when the Chinese table for determining the sex of the unborn child appeared, but there are suggestions that it was created based on the knowledge of Chinese culture and history.The Chinese, it should be noted, in general, all seek to verify with the calendars - lunar, agricultural, astrological. During the wars of dynasties for territoriality, the birth of boys was especially welcomed. Therefore, you can find information that the creation of the calendar is just one of those distant events that took place about seven hundred years ago.

The calendar, according to a popular legend, was discovered by archaeologists during excavations of an ancient temple near Beijing. It is said that he was stamped in stone and had signs suggesting that he belonged to the imperial court. This is nothing more than a beautiful legend. In China in the 14th century there was no Gregorian calendar, and the table was compiled using these months. In addition, the find (stone slabs) has never entered any museum in the world. Therefore, the Chinese calendar, quite possibly, is not at all Chinese, and not even a calendar, but it is in demand for women.

The method is based on the prediction of sex by age of the mother and the month of conception. It is assumed that at different ages a woman has different chances of having a daughter and a son. Age, of course, imposes an imprint on the fertility of a woman, it is scientifically proven that women over 35 have chances of having twins higher. But the floor is not so simple.

How to use the Chinese table, they do not know everything, despite the fact that finding it on the Internet is not difficult. To calculate the sex of the baby, you need to know the lunar age of the woman. They are considered to be not the age of the first cry in the hospital, but from the moment of conception of a person. If a woman is 22 years old with a passport, then in lunar equivalent it will be 22 years and almost 10 months. In the calendar in the column "age" you need to find the number 22. If a woman is 22 and a half years old with a passport, her lunar age will be 23 years and 4 months, and therefore in the column "age" you need to find the number 23.

Then everything is simple. Opposite your chosen age, the gender of the child will be indicated, depending on which month the conception took place or is still planned. Please note that you need to determine the date of conception, and not the month in which the last menstruation began. It happens that menstruation begins in late July. And the woman believes that in the table you need to choose "July." But ovulation has already happened in August, and therefore it is more correct to choose August just opposite to its lunar age.

To determine the sex of the baby using the Chinese calendar is simple. But how reliable? Women may be misled by instructions about the reliability of the method at the level of 70-80%. This is not true. First, this table does not take into account the age and other characteristics of the father, but still it would be more logical, because the sex of the child does not depend on the woman. According to reviews fair efficiency of the method - at the level of 50%, as well as without calculations at all. Either a boy or a girl.

It is not known for certain whence and when the Japanese calendar appeared, since there is no reliable information about this. According to one legend, astrologers in the land of the rising sun have long observed the movement of stars and planets and, as a result, came to the conclusion that the dates of birth of a man and a woman determine the sex of their offspring.The secret knowledge was conveyed to the emperor and transferred to women in the imperial family, since the Japanese rulers needed only sons.

The ancient origin of the Japanese table gives rise to the same reasonable doubts as the origin of its Chinese “friend”. But pregnant women, who want to know the sex of the baby within three weeks after conception at any cost, have little interest in the historical background of the methods.

In the first table you need to find the month of birth of the father and the month of birth of the mother. At the intersection of the row and column, there will be a certain number, which is called the number of coincidence. Remember this number and move on, go to the second table.

It presents the months of conception in relation to the number of coincidences obtained. It is necessary to find a match at the intersection and it will become clear whether a daughter or son is expected in the near future.

Despite the absurdity of statements about a certain dependence and cyclicity in the genetic set of gametes on the age of the mother and father, the feedback on the Japanese table, oddly enough, is rather positive. Women indicate that the probability of planning the baby’s gender by it is, of course, not 100%, but quite often the end result “coincides” with the prediction. More than half of such reviews, and therefore the accuracy of the method can be estimated at a record 60% for its analogs.

Official medicine is adamant - genetics do not see any connection between age, date of conception and the sex of the child. With age, the total number of sperm in a man does not change the balance between sperm with the genetic information of the twentieth century and the cells that carry the genetic set XY. This means that the probability of conceiving a boy or girl does not increase and does not decrease in a 40-year-old man as compared with a 20-year-old.

This method is as close as possible to traditional and official medicine, but again it only uses certain terms without substantiating speculation. Everyone knows that getting pregnant is possible only during the period of ovulation. In women with a 28-day classic menstrual cycle, ovulation usually occurs on the 14th day from the day of the beginning of the last menstruation. For women with a different cycle time, ovulation also occurs in the middle of the cycle. Ovulation is just a day, maximum - two days. That is, a woman is fertile only 1-2 days a month.

The conception method for ovulation is based on the statement that sperm XX and XY have a different lifespan, and also have a different speed when moving. So, it is believed that XY ("boy") gametes move faster, but they are less tenacious. And the XX-cells are less mobile, but they can survive for a long time, waiting for a convenient day - the day of ovulation, when the egg leaves the follicle and becomes available for fertilization. According to the method, favorable days for conceiving a boy are days of ovulation and days after her, and in order to become a mother of a girl, a woman is offered to have unprotected sexual intercourse before ovulation for a couple of days, so that the sperm XY by the time of the release of the egg were killed, and only the more survivable XX remained.

The feedback on the method is ambiguous. Approximately in the same proportions votes are distributed for “converged” and “not converged”. This makes it possible to judge that the reliability of the method does not exceed 50-55%. Then a reasonable question arises, why is the method considered to be near-medical? The fact is that the essence of the method is the difference in the characteristics of spermatozoa with a different set of sex chromosomes.Reproductive experts, no matter how hard they tried, found no differences in the speed of their movement, as well as in their ability to survive.

The only thing that cannot be doubted is the ability of the male germ cells to patiently “wait” for ovulation in the fallopian tubes. Sexual intercourse a few days before ovulation (3-4 days) may well lead to the onset of pregnancy, even if during the ovulation period the couple was protected or there was no sexual contact at all. But the sex of the child may be different - in 50% of cases, boys are born, with the same probability - girls.

In fact, this method will somewhat improve the Japanese calendar, since three indicators are used for the calculation: the date of birth of the parents and the date of conception of the fetus. The difficulty is that you need to know the date of conception, and with this usually there are difficulties, because ovulation can shift, be late, with an accuracy of one day to determine the date of conception is almost impossible.

Nevertheless, the creators of the method claim that the baby will inherit the gender of the parent whose numerical coefficient at the time of conception will be higher. It should be noted that the calculations are very complex. In the late 90s, Professor S. Dobrotin founded the method and tested it on the basis of the Gorky Maternity Hospital. Ultrasound then was not, and the method proposed by the professor, quickly began to use wildly popular. A newspaper article on the professor's theory caught the eye of programmer Mikhail Freiman, and he improved and systematized the calculations. It is to him that the tables belong, which today are used by those who wish to use this method to find out who should be born.

It is necessary to work with several tables. The first is called the father. It is necessary to find the year of birth of the father and the year of conception of the baby. A number will appear at the intersection of the column and row. We write it out and conditionally denote it as “number 1”.

The second table is also the father. It is necessary to find in it the month of birth of the father and determine what that year was - leap or ordinary. At the intersection, we find another number and write out - this is the "number 2". In the third table, choose the birthday of the father of the child, adjusted for how many days in the month of his birth. At the intersection find the "number 3". In the fourth plate, we choose the month of conception of the baby. Fix the "number 4". In the fifth table, we choose the day of conception and we look at what coefficient it corresponds to, so the “number 5” is obtained.

The sixth table summarizes the paternal coefficient. Get the sum of the five numbers that we wrote out and fixed earlier and find the coefficient corresponding to the sum in the sixth table. Next, you need to calculate the coefficient of women. To do this, you need to do all the same, but only with six subsequent tables, labeled as G1 - G6. Compare the two results. If the maternal number is higher, a girl will be born, if the paternal coefficient is higher, then a boy will be born. If you get two zeros or two identical other numbers, then you should expect the birth of a girl.

Budyansky are spouses who were teachers. Over time, they began to notice a certain pattern between the month in which the children and their mothers were born. As a result, they raised information about school students over the past three decades and made their own method of calculating the intended sex.

This method is based on the ratio of the maternal date of birth and the regularity of its menstrual cycle. The couple offered their own menstrual calendar. It is not 12, but 13 months, and in each 28 days. In fact, this is an analogue of the lunar calendar.

According to the calendar, a woman is invited to determine whether her menstrual cycle is of the type — even or odd. For this, she just needs to know her own date of birth and year. From the date, nine calendar months or ten lunar months are subtracted and another date is obtained. That it should be sought in the center of the table. Right and left - amendments to the even and odd year of birth (1980 - even, and 1981 - odd, etc.).

The owners of an even cycle in all even months will have a high probability of conceiving a girl, and in all odd ones - a boy. Owners of an odd cycle are all exactly the opposite - in odd months a girl can be conceived, and in even months a boy can be conceived. That is, the principle of conformity works - if the month coincides with the type of cycle, a girl is born.

According to reviews, the exact result of this method is obtained in 52% of cases, in 35% of cases there is no hit, and 13% of women claim that the method turned out to be true only for one of the children, and for the other, the calculation was erroneous.

There is no medical justification for the Budiansky method. But scientists have recently discovered that an egg can have different enzymatic potential in different cycles. As a timid assumption, American fertility specialists have suggested that the oocytes themselves “lure” spermatozoa of the desired type - XX or XY. To deny or confirm this has not yet succeeded, but the version has the right to exist.

The search for opportunities to predict the sex of a child before his birth has such an ancient history that it has become truly popular fun. There are many folk signs that women tried to guess about the gender of the unborn child. Let's look at the most common and popular.

A sign says that the round belly - to the girl, and pointed - to the boy. Medicine about this superstition says that the shape of the abdomen is in no way dependent on the sex of the baby.

The abdomen will be the form that nature provides, but rather the anatomical features of the woman. If the pelvis is narrow, the babies take on a more compact posture and the future mother's tummy looks rounded. In women with wide hips and pelvis, the abdomen somewhat "blurs", regardless of the baby of what sex she is carrying at the moment.

Affects the shape of the abdomen and the location of the fetus in the womb. If the baby is turned back to the right, the abdomen will be sloped to the right, if it is located head up, the tummy will look somewhat smaller.

Folk sign says that a woman who is pregnant with her daughter is less susceptible to toxemia. Her baby is also a future woman, and she is in some way solidary with her mother, and therefore will not bother her. But the boy in the womb can arrange a very troublesome life for her mother, especially in early pregnancy.

Doctors say that the very origin and causes of the development of toxicosis are poorly understood, but to the floor nausea, vomiting and a change in the perception of tastes and odors are clearly not related. There are women who do not experience toxicosis at all, but not all of them give birth to the promised omens on this occasion.

Folk sign says that boys are more active in my mother's womb, they are more likely to kick, and mother feels the most weighty butting in the bladder area. The girls are more calm, quiet, and if they are crawling, then somewhere in the region of the mother’s kidneys and liver.

Doctors categorically reject such claims. The motor activity of the fetus depends on it on the floor, and on temperament, character, and well-being, as well as on the mass of related factors (whether the mother is fed, whether she slept well, whether she normally feels, or not enough oxygen). A healthy baby moves quite actively.Regarding the location of the jabs and pushes, obstetricians explain that this depends on the location of the fetus. Where the legs - there tremors will be stronger, where the handles - there will be more “swarming”. Gender of the fetus on the presentation and position in the uterus is not affected.

In the people it is considered that the future mother of the boy eats from the first days of pregnancy a lot, often, with an appetite. She prefers meat products, fish, eggs, as well as salty and spicy. The girl in the womb, according to accept, makes the mother eat sweets and fruit. Also, a woman who should give birth to a daughter, from the first months becomes a favorite milk diet.

From the end of the third month of pregnancy, children in the womb really begin to distinguish between the flavoring nuances of the amniotic fluid, which they swallow. And all puzozhiteli without exception with great pleasure swallow water with a sweetish taste - glucose is pleasant to the child's body even in utero. But the fact that the mother chooses what products for their own food, boys and girls can not influence.

Therefore, taste preferences in carrying a child and his gender - are incomparable things. There is a theory that a woman intuitively chooses the food that contains the maximum amount of missing substances. If a pregnant woman eats chalk, she does so because of the lack of calcium at the time of the intensive growth of the infant’s skeletal system, and not at all because the child is a boy or a girl.

Folk sign says that women who after conception have blossomed and become prettier, have got a gentle flush and a brilliant look, will become mothers of boys. The girls, according to belief, select the beauty of mothers, but because the woman becomes swollen, becomes pigmented, suffers from falling hair and brittle nails.

Appearance pregnant and actually changing. But changes occur under the influence of hormones, in particular progesterone. It is he who leads to fluid retention in the tissues and the development of edema. It affects the production of melanin and makes it excessive, due to which pigment spots appear. Pimples in the early stages of pregnancy, blush, brilliant eyes - also merit hormones that provide the process of carrying a fetus from conception to childbirth.

The signs that women refer to as manifestations of the sex of the child are thus simply signs of pregnancy. Individual and diverse. The sex of the child has nothing to do with it. Strengthened or slowed growth of hair on the legs and in the armpits, swelling in the legs or arms - all this to the floor of the baby is irrelevant.

There are signs that can harm a woman. I want to dwell on them separately. So, for conceiving a girl, some folk “craftsmen” recommend douching with soda solution before sexual intercourse. Washing the genital tract with soda, in their opinion, reduces the acidity of the vagina, contributes to a better survival of the “frail” and “dead” XY spermatozoa. If you create an alkaline environment, they will get more chances to get to the egg and fertilize it.

The method is not suitable for a couple who are seriously tuned to future parenthood. Even a slight excess of soda in the solution can disrupt the natural balance of bacteria in the vagina, and even if the conception takes place, it is possible that immediately after two cherished strips on the test go to treat vaginosis.

A decoction of the uterus of the uterus, which is attributed not only to the miraculous properties of fertility, but also an increased likelihood of conceiving a boy, should be taken only according to the testimony of a doctor, and not because of a passionate desire to raise a son.It changes the hormones and can be quite harmful for women's reproductive health.

The method of determining the sex by movement often implies that a woman should lie on her back, in an uncomfortable position for her, and determine in which side her baby is tossed. It is better to refrain from such actions, because the growing uterus strongly squeezes the inferior vena cava in a supine position. A woman may lose consciousness, and the baby begins to act in such a position for a reason - it also suffers from impaired blood flow.

The most accurate way to order a child’s gender at the planning stage - IVF with genetic preimplantation diagnosis. But embryos obtained in the laboratory of germ cells of partners are selected by sex, according to the existing legislation, only when the birth of a child of a certain sex poses a mortal threat for him, for example, if a mother is a carrier of the hemophilia gene, she cannot give birth to boys, they will be sick.

Doctors select only embryos of a certain gender and place them in the uterus. Could there be a mistake? No, because the genetic set of a fertilized egg during the examination is quite obvious, like many inherited diseases.

A good way to know the sex of a child is to do an ultrasound scan. Not 100%, but from 75 to 95% depending on the duration of pregnancy. And this is not the 50% accuracy that we talked about when analyzing the individual methods and methods above. In addition, ultrasound will answer the other questions - whether the baby is healthy, whether there are twins in the tummy.

On the question of what to believe, the answer is quite simple - what you want, if only for the baby and the mother it was not harmful. If a woman observes the schedule of visits to the doctor, listens to qualified expert advice and in the evenings she guesses on a wedding ring suspended above her belly, or counts the sex of the child according to the table, there is nothing wrong with that. But you should always leave a share of probability for a miracle - sometimes ultrasound is wrong. Only nature does not make mistakes, which will accurately show who you are. But already in the delivery room.
