When pregnancy has already begun, the woman can not wait to find out the sex of the baby as soon as possible. Some want to prepare the appropriate interior for the children's room in advance, so they give the floor Special attention while others are just curious. Sometimes advance planning sex is necessary in the presence of hereditary pathologies that are transmitted only to the male or female line. With the help of ultrasound diagnostics, it will be possible to find out the sex of the fetus only at the 16th week of gestation, and even then, if the baby turns properly. Other determination methods are also used, such as the lunar calendar, Japanese or Chinese tables. You can also calculate the sex of the child by the date of conception, the age of the parents, ovulation, and even by signs.

Conception is carried out by the fusion of sperm with a female cell. In both cells, there is a genetic biomaterial containing chromosomes, which are responsible for how the sex of the child is formed. Our body contains female (X) and male (Y) sex chromosomes. Expectant mothers have two X chromosomes in the genotype, i.e. XX, while the male genotype is represented by one X and one Y chromosome - XY. If from the mother the baby can only receive female type chromosomes, the father has the ability to give both chromosomes. The result will depend on how the division of the genetic material occurs, and what chromosome the sperm will carry, which will fertilize the cell. Therefore, children can turn out both male and female. There is a huge difference between male and female chromosomes.

• The sex X chromosomes weigh more and contain more genetic information than the male. The spermatozoon, if present, has greater survivability, is able to move longer and more easily tolerates an unfavorable acidic vaginal environment. But at the same time, such sperm is heavier, therefore it moves somewhat more slowly, but fertilization is more likely.
• The Y chromosome weighs less and has smaller dimensions, respectively, carries less genetic material, so the sex chromosomes male type lighter and more mobile, but at the same time they are more vulnerable. Therefore, Y-chromosomes quickly lose motor activity and they die.

How to plan the sex of the child before conception? If a couple wants to give birth to a boy, then it is necessary to provide sperm with the Y-chromosome the most comfortable conditions for successful fertilization of the female cell. If you want a daughter, then you need to do the opposite - create difficult conditions for the sperm to survive, then only the strongest, but slow, with the female X chromosome, will be able to survive until the meeting with the cell.

What affects the process of gender formation

Experts have a lot of assumptions and theories regarding the factors affecting the sex of the unborn baby, but there is no 100% confirmation for any of them. One of the assumptions concerns the fact that the gender of the unborn child may depend on the characteristics of the diet and the age of the expectant mother. If a woman weighs less than 54 kg, then a girl is more likely to be born, while overweight mothers more often give birth to sons. But in practice, it turns out that fragile mothers successfully give birth to boys, and quite often.

There is another theory that explains what determines the sex of the child. This is the theory of parental age, according to which, against the background of age-related hormonal changes, parents develop a certain pattern regarding the determination of the sex of the child. Of course, the hormonal background affects the development of the fetus and the course of pregnancy, but is not a determining factor in relation to its gender.

Another assumption of scientists says that the conception of a child of a certain gender is possible subject to certain nutritional principles. So, to conceive a daughter, mommy should eat foods rich in calcium and magnesium (nuts, eggs, milk, etc.). To conceive a male child, mommy needs to eat legumes, meat and fish, that is, foods rich in potassium and sodium. It is also recommended for the daughter to consume sour fruits and juices. Such a theory is well founded. Such a diet makes the vaginal environment acidic, therefore, at conception, only a strong sperm with X chromosomes can reach the egg.

Choosing the sex of a child before conception is an unreliable business, because the fundamental factor in the process of gender formation is exclusively nature, which is quite difficult to influence.

Basic Calculation Methods

The most reliable way to determine the sex of the unborn child is an ultrasound, but this technique will be available only after the 16th week of the term. There are other ways to calculate the gender of the child. They do not guarantee 100% accuracy of results, but often show reliable data. The most common methods are:

Sex determination by day of conception

Any woman knows that getting pregnant is real only in certain days cycles are ovulatory. As a rule, fertilization occurs within 2 days before ovulation, during the ovulatory period itself and 48 hours after it. How to calculate the gender of the child using a similar method? This method based on distinctive features behavior of X and Y type chromosomes.

This has already been discussed, but we will explain again. "Female" sperm (with X-chromosomes) are slow, but have a high survivability, so they live quietly in the uterine body for up to 4-5 days, waiting for the release of the female cell. "Male" sperm bearing the Y-chromosome are quite nimble, but die quickly (in a day or two).

But how to determine the sex of the child by the date of conception? If sex without protection happened 3-4 days before the onset of the ovulatory process, then the calculation shows that there is a high probability of conceiving a daughter. If the sexual intercourse took place during the ovulatory period or immediately after that, then it is worth waiting for the son.

By mother's age

One of the methods for studying the gender of the unborn baby is based on the age data of the mother. Knowing exact age women, you can calculate the sex of the heir. There is an ancient Chinese table, which, according to historians, archaeologists discovered during excavations of the catacombs. The scheme is simple, the maternal age is taken as the basis for the date of the expected birth and the month of the completed conception, when the embryo began to form. The table is quite easy to use. We choose maternal age and month of conception. At the intersection of the corresponding column with the desired row, the desired result will be.

Calculate gender by ovulation

One of the most reliable methods for finding out the sex of a child was proposed by the Polish doctor Benedo. According to this method, the reliability of the results reaches 80%. The essence of everything is in the same chromosomes and their behavior. It is only necessary to accurately calculate the date of the ovulatory process. For this, special test systems are commercially available. You can also determine the onset of ovulation in terms of basal temperature, etc. When fertilized before planned menstruation, it is worth waiting for a son in 12-13 days, and a boy in 14-15 days.

Gender by age and blood of parents

In addition to determining the sex of a child by the date of conception, there is a theory of calculation by parental blood. There are two options. The first concerns the renewal of the blood. This theory shows fairly accurate results. According to scientists, blood is renewed at intervals of several years: every 4 for men, every 3 years for women. Also, blood renewal occurs in situations such as active donation, heavy bleeding, major surgical interventions, childbirth or abortion, etc.

You need to take the total number of years of the mother and divide it by 3. Let's make a calculation, let's say the mother is 26 years old, divide by 3, it turns out 8.7. We do the same with the age of the father, only we divide it by 4. Let's say the father is 27 years old, divide by 4, it turns out 6.8. We look at fractional balances. The mother has 7, and the father has 8, which means that the mother's blood is younger. The revealed result says that the couple in given age maybe a girl will be born. If the residuals turned out to be equal, then they speak of a high probability of the birth of twins. Although in practice this rarely happens.

Moon calendar

As you know, the moon quite strongly affects the life of all living things, including the gender of the unborn child. Astrologers believe that gender can be determined by the signs of the zodiac. There are six female and the same number of male zodiac signs. To determine the sex of the baby, you need to look at moon calendar and to know moon phase. If the Moon is in Aries, Gemini, Libra or Leo, Aquarius or Sagittarius, then there will be a boy. The rest of the zodiac signs indicate the birth of a girl.

In addition, the lunar calendar recommends the most auspicious days for conception - these are 24, 17, 7, 3 and 2 lunar day. But when calculating, it is worth especially considering the discrepancies in the days when the sexual intercourse and when conception happened. These dates may vary slightly.

Gender Test

There is such an invention as gender tests, which have American origin. Floor calculation by this test carried out in the same way as the determination of pregnancy, only the result will indicate the specific sex of the fetus, which can be determined starting from the 8-week gestation period. There are many varieties of such test strips, which differ in price, but the principle of their work is the same. You need to lower the strip into a portion of urine and look at the result - a bright blue or pink strip indicating the specific gender of the baby.

Practice shows that on different terms gestation results in the same woman differed. Women's reviews say that these test strips show only half the time correct values. But even without a test, the chances of having a baby, female or male, are 50/50.

According to signs

There are many folk signs that can indicate the gender of the unborn baby. Some of them are so absurd that they defy any logical explanation. One of these signs concerns the appearance of mommy. If a pregnant woman's hair becomes thinner, falls out or fades, pimples and acne appear on her face, attractiveness is lost, then they say that a girl will be born, as if the daughter, being in the womb, takes beauty from her. A boy cannot influence the appearance of a pregnant woman so drastically. Doctors say that it is impossible to find out gender by such a sign, because the hormonal status of a woman during pregnancy can change in different ways, the condition of the hair and skin depends on the hormonal background.

Someone keeps a conception calendar, while others try to determine the sex by the shape that the stomach acquires. It is believed that a low and sharp tummy indicates a son “living” in it, and a round and large one speaks of a daughter. There are enough signs regarding pregnancy, but do they work. Practice shows that the veracity of signs is considered an ordinary coincidence.

Is it possible to accurately calculate the gender of the baby

None of the methods described above can give a 100% accurate result. Moreover, ultrasound diagnostics is no exception, there are many cases when the sonographers were mistaken, as a result, the correspondence of the sex determined during the study did not coincide with the real gender of the baby. The reasons for the error are not related to lack of experience, just before the 18-week period, the external genital organs of the female and male type are very similar, which is the cause of the error. It is possible to accurately determine the sex of the baby only in such ways.

1. intrauterine test. A similar technique involves the behavior of chorionic villus biopsy and amniocentesis (biochemistry of amniotic fluid). These studies are carried out, observing a certain schedule - in the period of 11-14 and 15-18 weeks of the term. But let's make a reservation right away - these studies can be dangerous, so gender is not determined in this way. They are prescribed only when there are real suspicions about the abnormal development of the fetus.
2. ECO. How to determine the sex of the child in this way? When a woman undergoes artificial insemination, before the procedure of transplantation into the uterine body, doctors find out the sex of the embryo. In practice, such a study is rarely carried out, because it is considered unethical. Therefore, such a procedure is prescribed only to exclude possible pathologies that are inherited through the female or male line.

The remaining methods aimed at calculating gender are unreliable, therefore they cannot be considered reliable.

Determining the sex of a child by arithmetic calculations

This method of planning the sex of the future baby is ideal for women who have menstrual cycle stable for several months.

For example, as practice shows, if you have sexual intercourse 11-12 days before the onset of menstruation, then you will “get” a boy. If you need a girl, then you need to have sex 13-14 days before your period. Just on own experience can you make sure who will be born a boy or a girl? You did the right thing or you got it wrong.

The sex of the child by the blood of the parents

You can find out the sex of the child by updating the blood of the parents if you know the approximate day of conception. The essence of the method is that at the time of conception, whose blood of the parents is younger, then that sex will be born. In a woman, blood renewal occurs once every 3 years, and in a man - once every 4 years. To calculate, it is necessary to take the full years of the man at the time of conception and divide by 4, and the full years of the woman by 3. Whose result is less - that sex will be born.

Determination of the sex of the child by the number of years lived

There is also a rather bold theory - who will be a boy or a girl. According to this theory, it is possible to calculate the sex of a child by the number of years a woman has lived, even number years or odd. Adherents of this theory believe that the correct calculation will give the expected result - pregnancy: a boy or girl can be planned according to the following scheme, for example, if a woman has an even number of years, then the conception of a girl will be in even months - February, April, and June, etc. . You can predict the sex of a boy if the woman is an odd number of years, in odd months - January, March and May, etc. And also, vice versa: with an odd number of years lived by a woman, a boy can be "ordered" in even months, and a girl - in odd ones. Until now, no one can explain this phenomenon, but it works. You can check.

Method for determining the sex of a child by Evgeny Yonas

Evgeny Jonas is a Czech physician who tried to use the relationship of the moon phase with the conception of a child of a certain gender to determine the sex of a child or to conceive a child of the desired sex.

The method of determining the sex of a child by Evgeny Jonas is to first find out exactly the phase of the moon in which the expectant mother was born. By the way, the previous phase is considered the most favorable for conception. So, if this phase of the moon is in the female zodiac sign (Pisces, Capricorn, Scorpio, Virgo, Cancer, Taurus), then the conception of a girl is most likely. The reverse situation is true for conceiving a boy and determining the male sex of the unborn child.

This method of determining the sex of a child requires accurate data when conception occurred. But the very conception of a child, as a rule, does not coincide with the date of sexual intercourse. Spermatozoa that entered the female body during this sexual intercourse can live for several days and only then give birth to a new life. So the phases of the moon for sexual intercourse and conception may differ. This can significantly change the results of such determination of the sex of the unborn child.

Moreover, there is evidence that it is more correct to use this method not the phase of the moon of the birth of the expectant mother, but the phase of the moon of her conception.

Determination of the sex of the unborn child by heart rate

This method is often used by gynecologists, errors are rare. If the fetal heart rate is above 140 beats per minute, then it is a girl; if it is less than 140 beats, then it is a boy.

Determination of the sex of the unborn child using ultrasound

To date, ultrasound during pregnancy is the most accurate way to determine the sex of the unborn child. After 20 weeks of pregnancy, you can determine who you will have - a boy or a girl. But there are cases when determining the sex of the unborn child is impossible, for example, if he turned his back to the sensor, "sits on the priest" in the uterus or hides behind his legs.

Amniocentesis

In this case, the amniotic fluid surrounding the fetus is examined. Usually the method is used to diagnose various genetic abnormalities of the fetus, but the sex of the unborn child can also be determined with 100% accuracy. It is invasive, that is, penetrating, and entails certain risks, including miscarriage. Therefore, amniocentesis is performed according to strict indications. and never for the purpose of determining the sex of the child.

DNA test

Very accurate in determining the sex of the baby, but at the same time no less expensive, is a DNA test. It is not widely used: it is carried out in highly specialized laboratories and only for special indications.

Determination of the sex of the unborn child according to the ancient Chinese table

An ancient Chinese birth chart was found in a temple near Beijing 700 years ago. The time of creation of this table is the middle of the first millennium BC. The original is currently at the Institute of Sciences in Beijing. All you need to know is the month of conception and the age of the mother at the time of conception.

Using this table, compiled in accordance with ancient Chinese sources, you can plan the birth of a boy or a girl as you wish. Knowing in which month a boy (indicated in the table "m") or a girl (indicated in the table "d") will be born, you can plan the time of conception. Having conceived at will, it is also possible to provide, in accordance with the horoscope, the constellation and the sign of the Zodiac, which will determine to some extent both the fate and the character of the child.

Do you want to test yourself? First find the age of the mother, then correlate it with the month in which the child was conceived. You will get "m" or "d" for boy or girl respectively. So you can check your birth or relatives. Given the age of the mother, which is indicated in the table from 18 to 45 years, you determine in which month a boy or girl can be born, choose the preferred one and count nine from this month to get the time of conception.

The table "works", it is easy to make sure for every woman who has given birth, it is enough to remember the age when she became a mother and correctly calculate the month of conception. The correct result is obtained in 90% of cases. This result is slightly higher than the indications for ultrasound examination (ultrasound).

Are you working hard to conceive a child and want a boy or a girl? Then, after reading this article to the end, you will be able to calculate the sex of the child by the date of conception and not in one way, but in 10 systems that are actively used all over the world and have already helped couples give birth to exactly the “right” baby.

A little about genetics, what affects the sex of the child?

The process of conception is quite simple. The child comes with dad and stays with mom, more precisely, the sperm fertilizes the egg and the baby is born. What determines the sex of the unborn baby? Recall biology lessons, it was there that we were told that the sex of a child depends on the set of chromosomes responsible for sex (sex chromosomes). As you know, they go in pairs and are divided into female and male.

• male chromosomes are Y chromosomes. Spermatozoa, carriers of the Y chromosome, are smaller in size and weight than carriers of X, since they contain less genetic information. It is more mobile, but at the same time less tenacious than X carriers;
• female chromosomes are X chromosomes. If the spermatozoon has exactly it in the genome, then it is more tenacious, remains mobile longer and has a large number of genetic material (compared to Y). Such spermatozoa weigh more and move more slowly.

For each woman, the set looks like this (XX) - two female chromosomes. In men, things are different, their set looks like this (XY) - one female and one male chromosome. At conception, a woman gives only the X chromosome, but the man "has a choice" what to give the baby X or Y. It is on this "gift" that the sex of your unborn child depends.

For thousands of years, following the continuation of the human race, people, observing, have developed methods for planning a "desired" child. We will consider the most popular and, accordingly, the most effective, but since none of them has been proven scientific facts No one can guarantee a 100% result.

What is the meaning of the method of planning the sex of the child?

We figured out how the desired gender is obtained, now we will consider the meaning of the planning technique from a medical point of view. This method was studied by the demographer Gottfried Hatzold, and he put forward a theory based on scientifically proven facts, sperm weight and ovulation days.

Pregnancy occurs during the period of ovulation, and depending on the sperm (what type X or Y) that is nearby, the sex of the child also depends. How to correctly calculate the date of conception in order to get the desired result.

Do you want a girl? We calculate the date of conception for the girl. As already mentioned above, X-type spermatozoa are more tenacious and slowly move towards the target (egg), the process of advancement takes them up to 5 days. Accordingly, Y-carriers die and the result is a girl. It turns out that the date of conception should be 5 days before ovulation.

Would you like a boy? We calculate the sex of the child by the date of conception. Since Y-type sperm are lighter, they get to the egg faster, but they do not live long 1-2 days. Accordingly, the date of conception should be set 24-48 hours before ovulation.

How to calculate the sex of the child by the date of conception? TOP 5 ways to get the desired child

No. 1. For the renewal of the blood.

The method is based on determining which of the parents' blood was updated last before the date of conception. Whoever had this event last, the child will be of this gender, since the "fresh" blood is correspondingly more active.

For the strong half of humanity, this happens once every four years, and for the weak half, once every three. The calculation is done as follows (example):

Dad is 34 and mom is 30. We divide father's year by 4, and mother's by 3, we get:

Dad's blood is younger, so it must be a boy.

No. 2. By the age of the mother and the month of conception.

This method goes back centuries. Even 700 years ago, a table was developed in China, using the month in which the child was conceived and the age ( full years at the time of conception) of the mother, you can find out or calculate the sex of the unborn baby.

No. 3. According to the date of birth of both parents and the month of conception.

This version comes from Japan. People of the sun claim that the month of birth of each of the parents leaves its mark on the fetus, so to find out the sex you need to calculate certain number You can do this in the table below.

Further, in the second table Japanese method finding out the sex of the child by the date of conception, we find the resulting number from the first table. Under it we look for the month of conception and by the number of crosses we find out the probability of the sex of the unborn baby.

No. 4. Moon calendar.

Since the expression "as the stars converge" has not been canceled, then children can be conceived after consulting with them. Everything is pretty simple here. couple you need to know on what day the moon will find itself in the desired (male or female) constellation. And it is on this day to actively make love. But do not forget that conception occurs on the day of ovulation, on other days this method will not work.

No. 5. Hormonal research.

In this way, it is possible to determine the sex of a child only after conception, but on early dates. A blood sample is taken from the expectant mother and the amount of chorionic gonadotropin is determined. For women expecting a girl, it is about 18% higher than for mothers expecting a boy.

Basic rules accompanying the conception of a child

Like it or not, but any process has its own requirements and rules. And no matter what the date of sexual intercourse is, for the desired result (daughter or son), such rules must be observed.

General rules for conception date:

• The woman must be ovulating.
• On the scheduled date, it is necessary to have sex as often as possible.
• After each intercourse, place a pillow or folded blanket under your ass.
• On the eve of sexual intercourse, avoid overheating, freezing, alcohol and cigarettes.
• A woman must reach orgasm, this will create a favorable microflora in the vagina, which will allow spermatozoa to more easily "make their way" to the egg.

To get a boy you need:

• often have sex, this will contribute to the filling of sperm with carriers of the Y chromosome;
• sex positions should be used with maximum penetration;
• Three days before ovulation, use a condom during intercourse.

To get a girl you need:

• two weeks before the date of ovulation, keep sex to a minimum;
• the last sex should occur 2 days before the date of ovulation;
• make love in positions with minimal penetration.

Such rules will contribute to the conception of the desired sex of the child, but no one can give guarantees.

Do you believe in folk tales?

Before ultrasound devices appeared, they tried to predict the sex of the baby by observation methods. So, for many years, pregnant women were observed and conclusions were drawn after the birth of the baby. Here are some folk omens, which indicate the gender of the child:

1. If the fetus is already very active, constantly pushing the mother in all directions, then it means that the football player is growing - a boy.
2. A round, blurry belly that can be seen from the back of a girl. Sharp, which is invisible from behind - on the boy.
3. Sprinkles a woman, age spots appear, which means there will be a girl. It is she who takes her mother's "beauty from the face."
4. If mom gives sweets in food, then there will be a sweet princess, and if she prefers meat and spicy food, then the man grows.

If a pregnant woman has an awkward gait, her legs are widely spaced, then, most likely, the masculine principle living in the stomach makes itself felt. A graceful gait indicates the presence of a girl in the "belly".

1. If hair is actively growing on the legs, faster than it was before pregnancy, then the sex of the child will be male.
2. If a pregnant woman constantly spins near the mirror, constantly cleans herself up, changes her hairstyle several times a day, expect a daughter.
3. Eating bread, a woman prefers a crust - there will be a son, a crumb - a daughter.
4. If you ask a woman in a position to show her hands and she does it with her palms up, it will be a girl, but if the back is then a son.

You can plan the sex of the child by the date of conception, but as they say: "People assume, the Lord disposes." Work on the process of conception, give birth and no matter who the daughter or son is, it will be the most beloved the best child because it will be yours.
