Methods to determine the sex of the child with maximum accuracy. Folk signs of determining the sex of a child during pregnancy

Future parents from the first days after conception want to determine the sex of their child. There are many methods for this, but none of them gives a 100% result. The only accurate method for today how to determine the sex of a child is amniopuncture or chorionic biopsy. This is a rather complicated procedure for taking amniotic fluid and it is prescribed only to detect genetic abnormalities, if there is evidence for that, as it can provoke a miscarriage.

It is worth noting that the sex of the unborn baby is affected by the sperm that fertilized the egg. If he carried the X chromosome, then a girl will appear, and if Y - a boy.

Ultrasound to determine the sex of the child

The closest to the truth is the determination of the sex of the baby, and most importantly, it is available to everyone - through an ultrasound examination of the fetus. It, as a rule, is prescribed not only to find out the sex of the child, but to monitor the development of pregnancy and only on time, in accordance with international standards. So, the first ultrasound of the expectant mother is recommended to be done at 12-13 weeks in order to identify gross anomalies in the development of the fetus at an early stage. The next study is after 20 weeks. At the same time, the organs of the crumbs, which are already well visualized, are studied. The last ultrasound is performed when the pregnancy is full-term, and thus the volume of amniotic fluid, the weight of the baby, and the maturity of the placenta are determined.

During an ultrasound examination, the accuracy of determining the sex of a child depends on the gestational age, as well as the experience of the doctor conducting it. Until 8 weeks, the baby's genitals are not differentiated. Their formation in the fetus continues until about 12 weeks. But doctors agree that future parents can find out the sex of the child no earlier than 12 weeks of pregnancy. In boys, the scrotum and penis are visualized on ultrasound, in girls, the labia majora.

During the study, the doctor may erroneously determine the sex of the child: instead of the boy's penis, a loop of the umbilical cord or a finger is noticed, and the swelling of the girl's labia, passing over time, is very similar to the scrotum. It also happens when a boy hides his genitals behind his clenched legs, and parents are told that they will have a girl.

It is best to find out the sex of the baby on an ultrasound scan at 23-25 ​​weeks. During this period of pregnancy, the fetus is quite mobile, and most likely, the doctor will be able to consider its sexual characteristics. In the later stages, this can be difficult due to its small mobility and considerable size.

Many people wonder how then to accurately determine the sex of the child, even if ultrasound can be wrong. As mentioned above, there is only one such method - chorion biopsy. It is carried out at an early stage (7-10 weeks of pregnancy) and consists in drawing a small amount of amniotic fluid with a thin needle to detect chromosomal abnormalities.

The indications for this procedure are:

1. hereditary diseases associated with the X chromosome;
2. identification of certain genetic conditions, the establishment of twins.

This method of determining the sex of a child is not used without medical indications, but it gives an almost 100% result and allows you to calculate the sex of the child.

Sex determination by blood group

To use this method to calculate the sex of the unborn child, you need to know the blood type of each parent and match them. There may be the following variations:

• A woman is a carrier of the first blood group, and a man is a second or fourth. In this case, a boy should appear. If the mother has the first blood group - the father has the third or both have the first, then a girl should be born.
• A woman with the second blood type, and the father has the first or third. This means that the parents are waiting for an heir. If the mother has a second, the father has a fourth or also a second, a girl is expected to appear.
• Parents need to wait for the girl and with the third blood group in the mother, and in the father - the first. If the mother is a carrier of the third blood type, and the man has the first, third or fourth, then they need to expect a boy.
• With the fourth blood group in a woman and the second in the future father, we can talk about the birth of a girl. If the mother is the carrier of the fourth group, and the father is the first, third or fourth, then they are expecting a boy.

Opponents of this method of determining the sex of a baby speak of its implausibility, since in this case only same-sex children would be born to the same parents. But in many families there are children of different sexes.

Also using this method to find out the sex of the child, it should be borne in mind that the sex of the baby also depends on the Rh factors of the blood of the expectant mother and father. The birth of a boy is predicted with opposite Rh factors of future mothers and fathers. The girl will be born with the same Rh factors in her parents.

Determining the sex of a child by blood type is quite popular, but does not carry any scientific basis. Many question it, but for a change, you can try and use it to calculate the sex of the child.

Chinese table for determining the sex of a child

Parents in China have long used this method, as the Beijing Institute of Science says it can determine the sex of a child with 98% accuracy. To calculate the sex of the child in accordance with the Chinese table, you must specify the age of the expectant mother and the month in which the baby is expected to appear.

This method is also suitable for those who only want to plan the gender of the child. In this case, the table must indicate the age of the woman and the month of conception. Next, you can see the result of the intersection of these data. This will help determine the sex of the child in advance, and correctly approach the date of the intended conception.

It is worth noting that this table is over 700 years old, and its original is still kept in Beijing.

Determination of the sex of the child by ovulation

Many people know about this method of determining who will be born. It is scientifically established that closer to ovulation, the environment in the vagina becomes more alkaline, and therefore it is susceptible to X-chromosomal spermatozoa carrying a girl. This is due to the fact that they are slower and more stable, unlike the Y chromosomes.

Therefore, if the egg is fertilized during ovulation, then a boy is more likely to be born. If this happened a few days before ovulation, then most likely the future parents will expect a girl.

The moment of ovulation is determined by measurement. So, under the influence of progesterone, the temperature during ovulation rises by 0.4-0.6 degrees. There are also ways to help identify it. This is another way to plan the gender of the unborn child.

Useful information on determining the sex of the child

In addition to the basic methods that help to find out the gender of the child, the following important points can be noted:

• Spermatozoa, which are carriers of the male chromosome, unlike female ones, react poorly to negative external manifestations. For this reason, men who work in hazardous industries rarely give birth to boys.
• An important role is played by the hereditary factor. If a mother is from a large family with more than 4 children, then there is a high probability of a birth and she has a predominant sex among sisters or brothers.
• Also, the sex of the child depends on the chromosome that fertilizes the cell. Sometimes the female body refuses to accept the male cell. When trying to get pregnant, some women notice that there was a delay, but the pregnancy never occurred. The reason for this may be that the female body rejected the egg fertilized by the male sperm.
• Women and men with a strong-willed character are more likely to have a boy. And calm parents with a gentle character, as a rule, become the parents of girls.
• Girls are born more often in a family of smokers, as well as in men suffering from gout and some other diseases.
• British scientists have published a study indicating that in families where a man is older than a woman, as a rule, the first boy is born. If, on the contrary, the expectant mother is older than the man, then it is likely that their first child will be a girl. This rule applies only to determining the sex of firstborns.
• There is an opinion that the heart rate of the fetus over 140 times per minute indicates the birth of a girl, in boys the heartbeat is more rare.
• Scientists have also found that with prolonged male abstinence before conception, more viable female spermatozoa with the X chromosome remain in the semen. Males with a Y chromosome become weakened and will not be able to fertilize an egg. Therefore, after male abstinence, a girl is more likely to appear.

Folk ways to determine the sex of a child

Since ancient times, there have been a large number of folk signs that help determine the sex of the child during pregnancy. Here are the most popular ones:

1. If a waist line is drawn from the back of a pregnant woman, then she is expecting a boy.
2. Boys also push hard in the stomach.
3. If the appearance of the expectant mother has deteriorated due to poor skin condition in an interesting position, then she is pregnant with a girl.
4. The preference for salty foods, as well as cold feet, indicate the expectation of a boy.
5. Women who are waiting for an heir become clumsy, and the future mothers of girls are graceful.
6. Swelling in the legs is a sign of the appearance of a boy.
7. An active sex life before conception increases the chance of having a girl.
8. Increased hair growth on the legs indicates the expectation of a boy.
9. Thin and tall representatives of the fair sex most often give birth to girls, and short ones with a dense physique give birth to boys.
10. Young mothers under the age of 25 most often become parents of boys.
11. Early toxicosis is characteristic of a girl's pregnancy.
12. A low position of the abdomen is a sign of expectation of a boy.

One parent wants to raise a real man, and the other parent wants to take care of a pretty girl. But it is not so easy to predict the gender of a child. It is good that our people have accumulated a lot of signs, and we have many different ways in which you can try to determine the sex of the child, and even the sex of the second child.

In addition to folk omens, future parents also have modern methods in their arsenal that help determine even the sex of a child at an early stage. We will list for you all the known (among them folk) methods by which it is possible with a high degree of probability to accurately determine the sex of a child at an early or late date.

Medical methods for determining the sex of a child

With the help of ultrasound. It is quite possible to find out the gender of the child by ultrasound today. Are you interested in what gender the child is, when sexual characteristics are visible and where to go to find out? You need to go to the ultrasound room. Any experienced doctor will tell you that it is best to find out the sex of the child by ultrasound in the period from 22 to 24 weeks. Before this period, sexual characteristics are poorly visible, and later - the child may “not show” them to you, covering them with his hands or feet. So it is logical, it is better to find out the sex of the child when it is visible. This method is also called determining the sex of the child by weeks. That is why, if you meet somewhere a recommendation to determine the sex of the child by weeks, you can immediately and safely go for an ultrasound scan. In clinics with good equipment and extensive experience, the sex of the child can be assumed even earlier, even from 12 weeks - during the first screening. But these data are not yet accurate, and with more success you can achieve for a period of 16-17 weeks.

Genetic analysis. The sex of the child at an early stage allows you to find out a procedure called chorionic biopsy. But keep in mind that the procedure is not intended for those parents who want to predict the sex of the child early when it is visible, but the wait seems too tiring for them. This diagnostic method is not used to satisfy curiosity, but in order to completely dispel or confirm concerns about genetic gender abnormalities. This way you can find out the sex of your second child or firstborn, but at the cost of an increased risk of miscarriage or complications.

Folk ways to determine the sex of a child

Pay attention to the first child. To determine the sex of the second child, you can use folk signs. If your first child has a small dimple at the back of the head, then the youngest child will be of the same gender. Or, for example, if the first word of the first child was “mother”, then the second one will be female, if “dad”, then, respectively, male.

Sex for blood renewal. It is possible to determine the sex of the child by blood renewal with a certain degree of probability. It is generally accepted that in people with a certain frequency there is a renewal of blood. For example, in men this happens every four years, and in the weaker sex - every three. At the same time, if you decide to calculate the gender of your child by renewal, you should also take into account “unscheduled” renewal, for example, blood transfusion, blood donation, etc. There is nothing difficult in revealing the sex of a child by updating. If you are seriously planning to find out the sex of the child by blood, then remember: the child will be of the sex whose parent’s blood will be “younger” at the time of conception.
Example: father is 29 years old, mother is 25. 29/4=7.2 25/3=8.3. It follows that they will have a male child. The probability of the method is 52%. Well, here you have learned how to identify the sex of a child by blood.

Eastern tables. The sex of the unborn child by the age of the mother using oriental tables. To accurately determine the sex of the child by the years of the mother, you need to know her age at the time of the birth of the child, as well as the month of conception of the child. After that, at the intersection of two values ​​in the tables, you will find the gender of the child. This method has many names: the sex of your child by the date of his conception, the establishment of the sex of the child by the age of his mother, the sex of the child by the months of his conception, and so on. As you may have noticed, it is quite easy to determine the sex of the child by the age of the mother. The main thing is that you have the necessary table at hand, and then there will be no difficulties in determining the gender of the child by the years of the mother.

Belly shape. Finding out the sex of the child by the mother's belly is a rather interesting way of gender determination. It has long been believed that the boy sits neatly in the stomach, the stomach is “cucumber”, and nothing blurs on the sides. Whereas the girl in the abdomen gives it a shapeless appearance, the abdomen of the pregnant woman protrudes strongly on the sides. Of course, you are unlikely to determine the gender of the child by the belly with a 100% guarantee, but it’s hard not to agree that you can find out the gender of your child by the belly much faster than calculating the gender of your child by the years of the mother.

Conception in relation to ovulation. The sex of the child by menstruation can be determined with a high degree of probability. The only thing worth considering: determining the sex of the child by menstruation should be carried out before conception. This method has another name - the sex of the child by ovulation, but the meaning does not change from this. So, if you want to work on determining the sex of a child by ovulation, then you first of all should know that male spermatozoa (those with a Y chromosome) move faster, but they die faster, while the carrier of the X chromosome, that is the female spermatozoon, although slower, has a greater endurance. This gives us the ability to determine the gender of your baby by ovulation. Just if you want a boy, plan to conceive on the day of ovulation or immediately after it, and if you need a girl, conceive a day or two before ovulation. This is how the gender of your child is determined by menstruation.

Dates of birth of parents. The sex of the unborn child by the months of birth of the parents can be determined using special calculators on the websites. There you need to enter information about the parents of the unborn child to find out his gender. Determining the sex of a child by months is much faster and easier than, for example, determining the sex of a child by urine (yes, this also happens).

Sex determination with urine. The sex of the child is determined by urine as follows: Urine is taken from the expectant mother in the morning and mixed in a ratio of 1 to 1 with fresh milk. To determine the sex of the child in the urine, the liquid should be put on fire (gas) and wait for the boil. If the milk curdled before or immediately during the boil, it will be a girl. Otherwise, it's a boy.

Parents' blood group. In fact, identifying the sex of a child by the blood type of his mother and father is elementary simple if there is a table of compatibility of blood types at hand. You can easily find this table on the Internet, and then quickly find out the gender of the unborn child by group.

"Who are you waiting for?" is the most common question a pregnant woman hears. And even if she already knows the answer, there will always be a person who will undertake to guess the gender by some signs that "always work." But here's the strange thing: sometimes such predictions come true. Let's check?

Gender sign number 1: changes in the skin of the expectant mother

Many pregnant women change the properties of the skin due to hormonal changes in the body. It is believed that if the mother's skin has become more oily, then a girl will be born, and if the skin, on the contrary, dries, a boy will be born.

Gender Sign #2: Acne

A logical continuation of the first sign: acne on oily skin - to expect a girl, and normal smooth skin should set you up for the imminent birth of a son. Here we can also recall the popular belief that the daughter “takes away” the beauty from the mother, but the son, obviously, does not.

Gender Sign #3: "Shine"

There is a strong opinion that all pregnant women should “shine” with happiness. Foretellers argue with this: in their opinion, only future mothers of boys “shine”.

Gender Sign #4: Negro Line

This is a dark stripe on the belly of a pregnant woman. And from it, it turns out, they also guess the sex of the child. If the line is visible only below the navel, a girl will be born, if it goes through the entire abdomen, a boy.

Gender Sign #5: The Soda Test

This method of prediction is not for the squeamish. Mix two tablespoons of baking soda with urine. If the mixture sizzles, a boy will be born; if nothing happens, a girl will be born. They say that the accuracy of such a test reaches 80%.

Gender Sign #6: Hair Texture

Brittle and dull hair is a sure sign of a future daughter. Thick and shiny hairstyles are worn by the boys' mothers. Or maybe just change shampoo?

Gender Sign #7: Body Hair

If the hair on the body begins to grow quickly and thickly, the woman will give birth to a boy. If there are no changes in the hairline of the body, there will be a girl.

Gender Sign #8: Weight Distribution

Some pregnant women notice that all the pounds gained are concentrated in the stomach, for others, the weight is distributed throughout the body. The first sign is for the birth of a boy, the second for a girl.

Gender Sign #9: Leg Temperature

It is believed that those who are expecting a boy get cold feet. At least this misfortune bypassed the unfortunate expectant mothers of girls (with dull hair and problem skin)

Gender Sign #10: Swelling

Another problem that testifies in favor of the son. The legs swell and double in size.

Gender Sign #11: Eating habits

The vagaries of pregnant women in food are a classic of any pregnancy. Craving for sweets? Feel free to buy pink diapers, there will be a girl. Crunchy pickled cucumbers? A boy will be born.

Gender Sign #12: Belly Height

A low and sharp belly - to the birth of a son. Highly located belly - to the daughter.

Gender Sign #13: Father's Weight

It would seem that the future father has already done his job. But no, in his appearance, some also guess the sex of the child. If a man gains weight with his pregnant wife, a girl will be born.

Gender Sign #14: Headaches

It is quite logical that any couple expecting or planning to continue the family is interested in what determines the sex of the child. Unfortunately, the question of the gender of the baby is surrounded by illogical myths that contradict common sense and the laws of biology and physiology.

In our article, we will dispel these myths and figure out what determines the sex of a child in a person, and also consider who exactly it depends on - a man or a woman. Separately, we will touch on the question of what the sex of the child depends on when conceiving a child, and how this process can be influenced.

In contact with

Each human somatic cell contains 23 pairs of chromosomes that carry genetic information - such a set of chromosomes is called diploid (46 chromosomes). 22 pairs are called autosomes and do not depend on the sex of a person, therefore, they are the same in men and women.

Chromosomes of the 23rd pair are called sex chromosomes, since they determine the sex. These chromosomes may differ in shape, and they are usually denoted by the letters X or Y. If a person in the 23rd pair has a combination of X and Y chromosomes, this is a male individual, if these are two identical X chromosomes - female. Therefore, the cells of the female body have a set of 46XX (46 chromosomes; identical sex X chromosomes), and the male body - 46XY (46 chromosomes; different sex X and Y chromosomes).

Human germ cells, sperm and eggs, contain 23 chromosomes instead of 46 - this set is called haploid. Such a set of chromosomes is necessary for the formation of an already diploid zygote - a cell formed by the fusion of a sperm and an egg, which is the first stage of embryo development. But still, the sex of the child depends on the man. Why? Now let's figure it out.

Chromosomal set of men and women

On whom does it depend more - on a woman or a man?

Many are still asking the question “Who determines the sex of the child: from a woman or a man?” The answer is obvious if you figure out which sex chromosomes carry germ cells.

An egg always has an X chromosome, while a sperm can have both an X and a Y chromosome. If the egg is fertilized by a sperm with an X chromosome, the sex of the baby will be female (23X + 23X = 46XX). In the case when a sperm cell with a Y chromosome merges with the egg, the sex of the child will be male (23X + 23Y = 46XY). So who determines the sex of the child?

What gender the child will be depends purely on the sperm that fertilizes the egg. It turns out that the sex of the child depends on the man.

What determines the sex of the child at conception? This is a random process, when the probability of fertilization of the egg by one or another spermatozoon is approximately the same. The fact that the baby will be a boy or a girl is a coincidence.

Women with feminist inclinations will either have to accept the fact that the sex of the child depends on the man, or women will try long and tediously to influence themselves by modifying their diet, frequency of intercourse and sleep time, without in any way increasing the likelihood of having a boy or a girl .

Why does a sperm with a Y chromosome fertilize an egg?

During the ovulatory phase of the menstrual cycle, the egg is released into the fallopian tube. If at this time a woman has sexual contact with a man, the spermatozoa in the semen enter the vagina, cervical canal, and then into the uterus and fallopian tubes.

On the way to the egg, the spermatozoa have many obstacles:

• acidic environment of the vagina;
• thick mucus in the cervical canal;
• reverse flow of fluid in the fallopian tubes;
• woman's immune system;
• corona radiata and zona pellucida.

Only one sperm cell can fertilize an egg, and this sperm cell can be either an X-chromosome carrier or a Y-chromosome carrier. The position in which sexual intercourse takes place, what diet the man followed, etc. does not affect which of the spermatozoa will be the "winner".

It is believed that X-spermatozoa are more resistant to the "aggressive" environment in the female genital organs, but at the same time they are slower than Y-spermatozoa, but there is no reliable evidence for this.

Why folk ways and signs should not be taken seriously?

But because if you include logic and common sense, they have no justification. What are these methods?

1. Ancient calendar methods, for example:
   • the Chinese method of sex planning, depending on the age of the woman and the month of conception;
   • the Japanese method, where the sex of the baby depends on the month of birth of the mother and father;
2. Methods associated with sexual intercourse: abstinence (for the appearance of a girl) and unrestraint (for the appearance of a boy), various postures as a predictor of male or female baby;
3. Diet Methods:
   • to get a girl child - foods with calcium (eggs, milk, nuts, beets, honey, apples ...);
   • for a child-boy - products with potassium (mushrooms, potatoes, oranges, bananas, peas ...).

Now let's break it all down.

Chinese and Japanese methods involve the use of special tables to predict the sex of the baby. Who determines the sex of the child at conception? From the sperm that will fertilize the egg. The Chinese, on the other hand, stubbornly believed that the sex of the baby depends on the mother, therefore, this method is already deprived of any logical background.

Does the sex of the fetus depend on the woman? In the egg, in any case, there is only the X chromosome, therefore, it does not bear responsibility for whether a girl or a boy is born.

You can focus on the Japanese method if you firmly believe that the compatibility of couples is determined exclusively by a horoscope, because the essence of this option for determining gender is the same. Remember what determines the sex of the unborn child at conception by studying this method!

Can the dates of birth of two partners affect the fact that after many years of the sperm of a man, it will be the X- or Y-sperm that will be the most dexterous and strongest? Especially considering the randomness of the latter. This also includes all kinds of methods that promise the birth of a child of one sex or another, depending on the day of the menstrual cycle.

Another way to determine the sex of the unborn child

The pace of sexual activity, as well as diet, can affect the quality of sperm and the likelihood of fertilization, but not the sex of a potential baby. Modifications of sexual life are not among those factors on which the sex of the unborn child depends, since it cannot speed up the movement or increase the endurance of the “same” sperm.

Yes, and X-and Y-spermatozoa differ not in the amount of calcium and potassium, but only in a fragment of the chromosome containing DNA. And it’s not worth talking about the influence of a woman at all - we all remember which parent determines the sex of the child.

Consequently, folk methods for planning the sex of a baby are based on myths and ignorance of the features of the fertilization process, therefore they cannot be taken seriously. But you will find about what methods you can use to determine pregnancy at home.

Does the sex of the fetus affect the appearance of toxicosis?

What used to be called toxicosis is now called preeclampsia. Preeclampsia is the result of the pathological adaptation of the female body to pregnancy. The causes of gestosis include a violation of the hormonal regulation of pregnancy, immunological changes, hereditary predisposition, features of placental attachment, and many other factors.

Preeclampsia manifests itself in the form of hemodynamic disturbances (for example, an increase in blood pressure), deterioration in the function of the urinary system (pregnancy nephropathy, manifested in the form of edema, the appearance of protein in the urine, etc.), in severe cases, there is a pathology of blood clotting.

To the popular question “Does toxicosis depend on the sex of the unborn child?” There is only one answer: definitely not. None of the factors that cause preeclampsia, the gender of the fetus can affect.

All the first signs of pregnancy are described in detail in. A - it is painted for how long and with the help of ultrasound you can reliably find out the sex of the unborn child.

Useful video

It is known that the sex of the unborn child is determined at the moment of conception and depends on which sperm will fertilize the egg. Is this connection random, or can it be influenced in some way:

Conclusion

1. Spermatozoa are produced by the sex glands of a man, which suggests who determines the sex of the unborn child.
2. The fact that both X- and Y-chromosome sperm can fertilize an egg answers the question why a child's gender depends on the father and not on the mother.

If it's a girl:

• You will be sick in the morning
• Baby's heartbeat over 140 beats per minute
• You will gain weight in your hips and buttocks
• Your hair will take on a slightly reddish tint.
• The belly will look like a watermelon
• In food will experience a weakness for sweets, fruits, orange juice
• On the face you will see a blush
• Your urine is light yellow
• The first push of the baby in the tummy on the right

The theory of the intensity of the sexual life of spouses belongs to the weakly reliable. If a young man had a long abstinence, then most likely a baby will be born. If the couple makes love quite often, then a boy will be born.

This theory also finds scientific confirmation. "Male" spermatozoa do not live long, so a man will have a daughter after a long period without sex. In this case, the concentration of “female” spermatozoa is increased.

Another interesting way to identify a son or daughter. This can be done by looking at our dad! If the father is a little bald, then wait for the boy, but if the thick hair is a daughter. You should also expect a girl if your husband has great masculine strength and wears loose underwear.

Currently, there are simply a huge number of ways to find out if you will have a daughter or son. Which method you use is up to you. The most important thing is that the baby should be the most beloved and desired for future parents.

The question of how to determine the sex of an unborn child worries potential parents, perhaps no less than his health. In an effort to find out who will be born, some are guided solely by interest, others by principle. In any case, even today, in the 21st century, mothers and fathers resort to methods for this, often far from science.

The sex of the unborn child depends on the chromosomes carried by the spermatozoa.

What factors determine the sex of a child, everyone knows from the school anatomy course. During intercourse, a huge amount of sperm enters the vagina. True, only the most persistent get to the cervical mucus, while most of them die in an acidic environment. After that, the “lucky ones” cross the uterine cavity and find themselves in the fallopian tube, where they meet with the egg.

The egg is the carrier of the X chromosome, while the spermatozoa that fuse with it can be carriers of both X and Y chromosomes. In the first case, a female embryo (XX chromosomes) is born, in the second - a male (XY).

Scientifically proven methods that allow you to calculate the sex of the child in advance, before conception, do not exist. This can only be done during pregnancy, using ultrasound or amniotic fluid analysis.

Methods for determining the sex of a child

We list the most popular ways to influence the gender of the fetus and determine it after conception. All of them are free, feasible on their own, but the reliability and accuracy of these methods are in big question.

By date of conception

Of all the methods that will be discussed below, the method of determining sex by is the only one that has a scientific justification, but even taking this into account, it is not accurate. The technique is based on the fact that spermatozoa carrying the Y-chromosome are more active. On the day of ovulation, they are the first to reach the egg and fertilize it. Therefore, if you correctly determine the date of ovulation, you can plan the conception of a boy.

Sperm with X chromosomes are slow, but more stable and tenacious. In the female genital organs, they can be and remain active for up to 7 days. Thus, if sexual intercourse took place a few (3-4) days before ovulation, only sperm with X chromosomes will remain alive by its onset, which means that a girl will be conceived.

This method, despite its physiological nature, will work only if a woman has a perfectly regular cycle, and is not affected by stress, common diseases, changes in air temperature, pressure and other factors.

Gender determination according to the table

A kind of "calculator" of the sex of the child online - ancient tables that take into account the dates of birth of the parents and the date of conception. The most popular among them are the Japanese and Chinese calendars.

• Japanese version

The Japanese calendar, based on the principles of astrology and numerology, consists of two parts. The first table defines a number that links the dates of birth of the potential father and mother.

Table No. 2 shows the probability of having a child of one sex or another. In the top line, you need to find the number determined using the first table, below it - the month in which the conception occurred. The crosses next to it indicate the probability of conceiving a boy or a girl: the more crosses, the higher it is.

• Chinese calendar

The Chinese calendar, like the Japanese one, is based on long-term observations and the systematization of their results. It is based on the calculation of such parameters as the location of the stars at the time of conception, the phases of the moon and others. In an adapted and simplified form, it looks like this:

Internet forums claim that Eastern calendars are remarkably accurate. Scientists, on the other hand, believe that accurate predictions are nothing more than random coincidences, since sex is determined not by the time of conception, but by the sperm.

By the blood of the parents

The blood of the parents, of course, plays a huge role in the formation and development of a healthy fetus. However, there are theories that it affects not only health, but also gender.

• Blood type

According to this version, the sex of the child is determined by the blood types of the mother and father and their combination.

Man	Woman	Child
I	I	D
II	I	M
III	I	D
IV	I	M
I	II	M
II	II	D
III	II	M
IV	II	D
I	III	D
II	III	M
III	III	M
IV	III	M
I	IV	M
II	IV	D
III	IV	M
IV	IV	M

The Rh factor also affects the accuracy of calculations:

Man	Woman	Child
-	+	M
+	-	M
+	+	D
-	-	D

The main question that this method raises and which casts doubt on its reliability is why the same parents give birth to children of different sexes?

• Blood renewal

An equally controversial way of planning at home is to renew the blood. According to this theory, women's blood is renewed once every 3 years, and men's - every four years. If at the time of conception the blood of a man is younger, a boy will be born. Accordingly, if the woman’s blood turns out to be younger, you can expect a daughter. In this case, it is necessary to take into account such events as blood transfusions, abortions, large blood loss. If they took place, the countdown should start from them.

It is very simple to calculate the years when the blood is renewed: for a woman they are a multiple of three (18, 21, 24, and so on), and for a man - four (20, 24, 28, and so on). Thus, if the expectant mother is 25 years old, and the future dad is 27 years old, it is worth waiting for a girl, because the renewal of the mother's blood happened a year ago, and the father's - three years ago.

By heartbeat

How did doctors determine the sex of a child without an ultrasound before? Mothers and grandmothers may recall that the midwife listened to the fetal heartbeat with an obstetric stethoscope. The heart of the fetus begins to contract as early as two weeks after conception, you can fix its beats for a period of 7-8 weeks, and try to determine the sex - not earlier than 12 weeks, when the organs take shape in the fetus. To determine gender, pay attention to the following factors:

1. Beat frequency: in girls, the heart beats more often (about 150 beats, while in boys it is 120-130).
2. Rhythm: the heart muscle of boys contracts more rhythmically and louder, in girls it is more chaotic and muffled.
3. Location of the fetus: if the heart beats are heard on the left, they talk about a boy, if on the right, about a girl.

Today, medicine is skeptical about this technique. The characteristics of the child's heart are not constant indicators; they depend on the state of health of the mother, sleep or wakefulness, the position of the mother's body at the time of diagnosis, and other factors.

By menstruation

The method of determining sex by menstruation is based, first of all, on statistical data collected and processed by Japanese scientists. They found that the earlier a girl began her period, the more likely it was that her future children would be dominated by girls.

Thus, 10 thousand mothers were interviewed. Those of them who first “got acquainted” with menstruation at the age of 11-12 bring up mainly girls.

Scientists concluded that this dependence is determined by the level of estradiol: the more it is in the body, the earlier menstruation begins.

By mother's age

A calculation method based on the age of the parents, especially the mother. The main criterion is the evenness of the age and the evenness of the month when the conception occurred.

1. A woman of even age (22, 24, 26 and beyond): conception in even months (such as February, April and others) - daughter, conception in odd months (January, March and others) - son.
2. Woman of odd age (19, 21, 23, and so on): conception in even months - son, conception in odd months - daughter.

By the phases of the moon

According to the postulates of ancient Indian medicine, conception should not occur on 11 or 13 lunar days, as well as on the full moon and new moon. For a boy to appear, you need to have sex during the days of the male signs of the Zodiac - Gemini, Leo, Cancer. The female signs are Taurus, Leo and Libra.

Another theory of the connection between the phase of the moon and fertility belongs to the Czech scientist Jonas. He believed that in ancient times, when the unity of man and nature was completely harmonious, a woman's ovulation coincided with the lunar phases favorable for conception. Now this harmony has been broken, and therefore the correct days have to be calculated.

According to the scientist, the most favorable for conception is that phase of the moon, in which the future mother herself was born. The task of a woman is to calculate the optimal fertile days, focusing both on her own ovulation and on the corresponding lunar cycle. Every 2.5 days, the Moon moves from the male to the female zodiac sign. If the fertile period falls on a male sign, you can plan a son, if on a female, a daughter.

According to food preferences

Many future parents are sure that it is possible to plan a child of the required gender with the help of a diet that must be followed for two months before conception, and both parents. The nutritional recommendations are as follows:

1. For the birth of a girl, you need to eat vegetables, dairy products, sweets, local seasonal fruits.
2. In order for the family to be replenished with a boy, it is worth focusing on meat, potatoes, tropical fruits, and mushrooms.

Preferences already during pregnancy is also one of the home methods for determining sex. The expectant mother is drawn to salted, smoked, meat - which means she is expecting a boy. If she wants sweets, there will be a girl.

The question arises: if a woman adheres to a certain diet before conception and during pregnancy, how will this affect the health of the fetus and the expectant mother herself? For example, a meat and, in general, any protein diet in an effort to give birth to a boy is a rather serious blow to the kidneys, which already have a hard time during the period of expectation of a child.

Folk omens

Pregnancy is an event of great importance in the life of every woman, so the waiting time for a child is surrounded by many signs, including those related to sex determination. By what signs, according to popular signs, can a forecast be made? We list the most famous among them.

• Appearance

If a woman expects a girl, she changes outwardly for the worse: the future coquette "takes away" her mother's beauty. Indeed, many women become stupefied while waiting for a child, but this is not the fault of the daughter, but of physiology - hormones, excess weight, edema and other unpleasant factors that often accompany 9 months.

• Toxicosis in the first trimester

Signs say that it is stronger in expectant mothers of boys. This is due to the fact that it is easier for the body to adapt to bearing its own likeness. Meanwhile, the mechanism of development of toxicosis is not fully understood. Hormones, the central nervous system, and other factors are “guilty” of its appearance. But science does not know about the influence of the sex of the fetus on the development of toxicosis.

• Intrauterine behavior of the fetus.

The future bully often moves, but the princess behaves much more calmly. Medicine, of course, agrees that the movements of the fetus must be monitored, but not to determine the sex, but to assess its condition. So, too frequent movements may not indicate a boy at all, but that the baby does not have enough oxygen.

• The shape of the abdomen in the later stages, after 28 weeks.

A sharp belly, which is not visible from the back, is a sign of a boy, round and as if spreading to the sides - girls. And medicine refutes this sign: the shape of the abdomen depends only on the anatomical features of the expectant mother, the presence or absence of excess weight, the location of the fetus in the womb.

There are other, less well-known ways to plan the baby's gender:

• in order for a boy to be born, a woman at conception must lie down with her head towards the north, and if a couple dreams of a girl, towards the south;
• if you make love in dry weather, a boy will be born, in the rain - a girl;
• for a girl to appear, a spoon must be hidden under the pillow during an act of love;
• boys are born in cool rooms, and girls in warm ones;
• if a husband loves his wife more than she loves him, you can expect a son.

There are not only signs, but also various funny divination on the sex of the child. For example, it is believed that if a pregnant woman eats bread, starting with a crust, then she is waiting from her son, and if from a crumb, then her daughter. Fortune-telling on the key is also known, which advises asking the expectant mother to take an ordinary key from the table. If she takes the head of the key, it will be a girl, and if the tip, then a boy.

Of course, there is nothing wrong with these fortune-telling. But only if you do not place high hopes on them, as well as on signs, and treat them with humor.

Folk signs on the gender of the child

scientific methods

By nature, it is conceived in such a way that approximately 105 boys are born for every 100 girls in the world. This is due to the fact that boys are genetically experimenters, discoverers who move the world forward, and therefore often take risks and die. Interference with the laws of nature and the impact on the sex of the child by scientific methods is a very controversial issue. However, some technologies that are used in IVF exist (they are not used in Russia).

1. Robert Erickson's method is based on the division into fractions of spermatozoa with male and female chromosomes. On the day of female ovulation, a man donates sperm, which is processed with the help of albumin protein. It is assumed that sperm with male chromosomes will move faster through albumin, and therefore they will be at the bottom of the tube earlier. After that, the doctor selects the "necessary" (male or female) sperm and spends.
2. Laser separation of spermatozoa. Sperm with X and Y chromosomes are separated from each other using a laser. True, the authors of the technology do not promise a 100% guarantee and accuracy - for example, in the case of boys, success is only 75%, since spermatozoa with male chromosomes, as already mentioned, have a low survival rate.
3. . The technique involves, first of all, the identification of genetic diseases in the fetus and is carried out if there is reason to assume their presence. During the diagnostic process, it is possible to determine the sex of the future fetus, but only for the purpose of informing parents: it is forbidden to choose a boy or a girl in Russia.

Other studies are underway, but all of them cause an ambiguous reaction from scientists, primarily for ethical reasons. One thing is clear: the main thing is not what gender the baby will be born, but his health and the attitude of his parents towards him already at the moment of conception.

It is known that the female egg contains one sex X-chromosome, and the male spermatozoon can have both the X-chromosome and the Y-chromosome different from it. If the egg is fertilized by an X-chromosome similar to itself (the so-called female), then a girl is born. If the egg is fertilized by the Y chromosome (male), then a boy is born.

Interestingly, the female chromosomes are rather slow, they are even 1% heavier than the nimble, small and mobile male chromosomes. But the female chromosomes are more adaptable and tenacious, but the male chromosomes remain “combat-ready” only for 3 days. Knowing this, you can guess the right time to conceive a child.

According to statistics, it is also known that:

• Boys are more likely to be born at first births
• The younger the parents, the more likely they are to conceive a boy (and vice versa)
• If pregnancy occurs soon after an abortion, girls are more likely to be born
• Weather children are usually of the same sex
• If the interval between births is more than 3 years, children of the opposite sex are born

Methods for determining the sex of a child by date

The egg is ready for fertilization at the time of ovulation and the next 12 hours when it is in the fallopian tube. This is the life span of the egg. Therefore:

• if sexual intercourse took place 3 days or more before ovulation, the female X chromosome is likely to fertilize the egg (the alkaline environment in the female genital tract favors female chromosomes). This means that a girl will be born.
• if sexual intercourse occurs during ovulation or the next day, most likely the first before the start, that is, before the egg, the sprinters - Y-chromosomes will run (the environment in the genital tract changes, becomes acidic, which is more favorable for male chromosomes). This means that a boy will be born.

Forecast accuracy: 65%

The main condition for this method is the correct establishment of the day of ovulation. The easiest way is to determine basal temperature. It must be measured at certain hours - from 5 to 6 or from 8 to 9 in the morning for at least three cycles. The day when the temperature rises to 37.1 - 37.2 is the day of ovulation.

However, do not forget that the day of ovulation can change under the influence of various factors (climatic, psychological, physical ...)

Early determination of the sex of the child by updating

Another "modern" method... abstaining from sex. It is assumed that in the case of prolonged abstinence in the body of a man, special antibodies are produced that suppress the male chromosomes. Therefore, after a period of abstinence (at least one and a half months), female chromosomes remain in “vigorous health”, which means that the probability of having a girl is high and vice versa.

Forecast accuracy: 25%

Accurate determination of the sex of the child by blood renewal

promoted in European countries blood renewal method. This theory is based on the fact that the blood in the body of a man is completely renewed every 4 years, in the body of a woman - every 3 years. The child will be born of the sex whose blood was “younger” at the time of conception.

To determine this, you need to divide the total number of dad's years by 4 and the total number of mom's years by 3, and then compare the results. Whose remainder is greater, the child will be born of that gender.

Attention! If the expectant mother has a negative Rh factor, the result will be just the opposite.

Forecast accuracy: 51%

Determination of the sex of the unborn child by nutrition

Also Known baby gender planning method through diet. Moreover, both parents must comply with it, it should begin a month and a half before the intended conception. Scientists have developed special diets.

Future gender of the child: boy

Food should be rich in sodium and potassium. Eat potatoes, mushrooms, lentils, bananas, apricots, oranges, peaches, dates. Eliminate green salad, raw cabbage, nuts, beans from the diet.

Future gender of the child: girl

Food should be rich in calcium and magnesium. Eat dairy products, eggplant, beets, carrots, bread, onions, nuts. Eliminate plums, bananas, currants, melons, rice from the diet.

Forecast accuracy: 35%

Along with modern methods determining the sex of the child There are also ancient methods. Some of them are based on superstition, but there are also such methods, the correctness of which cannot be doubted.

Chinese horoscope for determining the sex of a child

In China, many mothers and fathers still use the well-known baby sex chart, which eight centuries ago was kept in one of the temples near Beijing. Now the document is in the Beijing Institute of Sciences.

To find out the gender of the baby, you need to know the mother's age at the time of conception (vertical line) and the month of conception (horizontal line). At the intersection of these two components there is a letter, which will tell you what gender the child will be born.

Prediction accuracy: 90%

Methods for determining the sex of the child: IVF - pregnancy

In principle, modern medical technologies make it possible to separate male chromosomes from female ones and artificially fertilize the egg with the “necessary” chromosome. This technology is called ECO (in vitro fertilization). True, in this case, it will not be possible to get pregnant without the help of doctors and modern reproductive technologies.

Forecast accuracy: 91% for boys, 75% for girls.

Table for determining the sex of the child

Designations in the table: M - boy, D - girl

Mother's age

And finally, one more method - concentrate on your unborn child, dream about him, because the main thing is the strength of your common desire!

Signs for determining the sex of the child:

• If you want to conceive a girl, place a wooden spoon and scissors under the mattress and a red ribbon under the pillow.
• Eat bread rolls, then you will have a boy, but if you eat only the crumb, a girl will be born
• Sleep on the left side, then a girl will be born, on the right - a boy.
• If a woman loves more in a couple, a girl will be born. Instead, it's a boy.
• In order for a girl to be born, you need to get out of bed in the morning on your left foot, so that a boy is born - on the right.

Gender of the child by the blood of the parents:

Gender of the child: table of the Rh factor of the parents

Of course, it will not be possible to determine the sex of the child by the date of conception with a 100% guarantee. After all, Mother Nature herself decides who should be born - a boy or a girl. However, if you know exactly or approximately the day on which, you can use the table of the sex of the child by the date of conception even before the ultrasound shows the exact answer.

Which parent determines the gender of the baby?

Recall the course of school biology. The gender of the future man is determined by the combination of chromosomes: XX for girls, XY for boys. It is the Y chromosome that is “male”, and only the father can pass it on.

children.mail.ru

The sex of the baby depends entirely on the father, or rather, on which set of chromosomes the sperm that fertilized the egg has.

Gender of the child and date of conception

Fact: spermatozoa that carry the female set of chromosomes "weigh" more and move more slowly, but are more survivable and resistant to adverse conditions than theirY-brethren.

Simply put, "boy" sperm cells move faster, and therefore get to the egg faster. However, if it took place before ovulation, they will not have time to do this, as they will die earlier. But the more stable "girls" will remain and at the decisive moment will be directly near the egg.

Conception directly on the day of ovulation and for several days after it increases the chance of. If sexual intercourse occurred earlier, the probability of having a girl is higher.

Difficulties of calculation

Although the described method does have a scientific basis, in practice deviations are quite common.

sputnikdestva.ru

To plan the sex of the unborn child by the date of conception, you must clearly know the day of ovulation. If you have been planning a pregnancy for a long time and used special tests, there will be no problems.

However, the usual calendar method, for example, can fail. This is due to the fact that even in women with a regular menstrual cycle, slight disruptions can occur. Stress, climate change, colds, various health problems, and even banal fatigue can affect this.

Alternative ways to find out the gender of the child

The methods below have no scientific justification, they are from the field of astrology and predictions. However, since they have been used for so many centuries, perhaps they really work.

Moon calendar

Astrologers claim that the reliability of this method reaches 95-97%. Believe them or not, let everyone decide for themselves. We will just briefly describe the essence.

The duration of the lunar month is 29 days - this is the period during which the moon makes a revolution around our planet.

Lunar calendar | onlineanswerchik.ru

It is believed that you can find out the sex of a child by the date of conception by finding out in which zodiac constellation the Moon was on that day. Gemini, Leo, Libra, Aquarius, Sagittarius and Aries are considered "male" signs, and Cancer, Virgo, Scorpio, Capricorn, Pisces, Taurus and Virgo are considered "female" signs.

Chinese calendar

To determine the sex of the child by the date of conception, people have sought at all times. And this is most eloquently proved by the ancient Chinese calendar, found in an ancient temple about 700 years ago (now the original is kept in the Beijing Museum).

In ancient China, it was believed that the sex of the baby depends only on two factors: the date of conception and the age of the mother.

Important: in order to calculate everything correctly, a pregnant woman needs to add 9 months to her real age. This is due to the fact that, according to tradition, in the Celestial Empire, the “reference point” was considered not the birthday of a person, but the date of conception.

puzenush.ru

Using this calendar to calculate the gender of the child is very simple. For example, if a woman is 25 years old, 1 year must be added to her age. It is necessary to find the appropriate column with age, the month of conception of the baby (for example, March), draw straight lines and find the place where they intersect. The table indicates "M" - this month, the probability of conceiving a boy is higher.

Japanese table

The next way to determine the sex of the child by the date of conception is to use the Japanese table. Japanese scientists believe that X and Y chromosomes are produced at certain periods of time. When the number of “necessary” spermatozoa prevails, the chance of conceiving a child of the desired sex is higher. Unlike the Chinese calendar, this method takes into account the age of the father.

The table consists of two parts.

1. Find the number and remember the number at the intersection of the months of birth of the father and mother of the baby.

2. Go to the second table and find the required number in the horizontal line, and the month of conception in the column. Depending on where there are more crosses (in the "Boy" or "Girl" column), the probability of conceiving a baby of the desired gender is also higher.

Conception date calculator

If you are too lazy to understand various tables on your own, you can use ready-made calculators.

The most popular resource of this kind in Runet is the Nyanya.ru website. Here you can calculate the sex of the child by the date of conception with a calculator based on ancient Chinese or Japanese tables. Everything is as simple and convenient as possible: you just enter the necessary data, press the "Calculate" button and in a matter of seconds you will receive an answer to your question.
