Methods for determining the sex of a child: female and male chromosomes. Calculation of the sex of the child by updating the blood
Surely, almost every pregnant woman would like to know in advance who will be born to her: a boy or a girl? This question is asked by any expectant mother, even if she firmly decided not to resort to any methods of determining the sex of the child.
If you decide to find out the gender of your unborn baby, you can use one of the methods that are described in this article. Even if you have a very short gestational age, determining the sex of the unborn child is possible! The main thing is to choose the right way!
How to determine the gender of the unborn child?
First of all, it is, of course, evidence-based methods. There are two of them:
- Chorionic biopsy. Using this procedure, you can determine the sex of the unborn child with 100% certainty. It is carried out for a period of 6-10 weeks only for medical reasons, since this procedure may threaten the birth of a child. With the help of a special needle, several cells of the future placenta are removed from the uterus. Only, in order to find out the sex of the child, a biopsy is not recommended.
- ultrasound. This is the most common and well-known scientific method. But, unfortunately, not always reliable. The most accurate result can be obtained after 23 weeks. And only sometimes, it is possible to determine the sex of the unborn child at 15-16 weeks of pregnancy.
In addition to scientific methods, there are many methods How to determine the sex of a child. After all, ultrasound diagnostics appeared quite recently, and women have always wanted to know who you have to be born, therefore, for many millennia, various methods for determining the sex of a child have been passed down from generation to generation. Here are just a few of them:
How to determine the sex of the unborn child by the date of ovulation
Determination of the sex of the child by the date of ovulation is based on the difference in spermatozoa. As you know, sperm carriers of the Y chromosome are more mobile and agile. During fertilization, they are the first to reach the egg, and therefore the sex of the unborn child is male. But, if at the moment of proximity ovulation has not yet occurred, then the spermatozoa carriers of the Y chromosome will soon die. Unlike them, sperm carriers of the X chromosome can wait 2-3 days for the right moment. In this case, we must wait for the birth of a girl.
How to determine the sex of the unborn child by the blood type of the mother and father

Table determining the sex of the unborn child by the Rh factor of the blood of the parents
But, this is a very dubious way to determine the sex of a child, because such an approach would mean that a couple of a man and a woman could only have same-sex children.
New blood method
This method is considered one of the most common. It is based on the "Blood Renewal" theory. In a woman, blood is renewed once every three years, and in a man once every four years. In order to determine the sex of the child, it is necessary to calculate which of the parents had more “young blood” at the time of conception. For example: Future dad is 29 years old, mom is 23 years old. We divide 29 by 4, we get 7 and the remainder is 1, 23 is divided by 3, we get 7 and the remainder is 2. And so, 2 is greater than 1, which means that a girl will be born. If, during division, equal remainders are obtained or one of them is equal to zero, then twins may appear.
Determination of the sex of the child by the father
Yes, and this is possible. There are some signs by which it is supposedly possible to determine who will be born - a boy or a girl.
- It is believed that bald men have sons one and a half times more often than men with lush hair. So, if your chosen one is bald, expect a boy.
- If the future dad has great male power, then wait for the girl.
- A man wears tight underwear - a boy will be born, free - a girl.
Well-being and appearance of a pregnant woman
- If you are experiencing severe toxicosis, then expect a boy
- Mothers of boys during pregnancy have a tendency to sour and sweet foods, as well as meat. But the mothers of girls, on the contrary, become sweet-toothed and consume various sweet buns and fruits in large quantities. In addition to different food preferences, the appetite of expectant mothers also matters. So mothers of boys want to eat much more often and more.
- If a pregnant woman experiences chills, then she will have a girl, bouts of suffocating heat - most likely a boy.
- If, in a future mother, the hair on her legs suddenly began to grow sharply, this indicates that there is a boy inside her. In addition, the constantly cold feet of the pregnant woman also indicate the boy.
- Nipple halos are light - a boy, dark - a girl.
- A woman became ugly during pregnancy - a girl, prettier - a boy. In mothers of girls, the amount of sex hormones, which are so necessary for the child, decreases, therefore, swelling of the face often appears in mothers, age spots.
How to determine the sex of the unborn child according to folk signs
- It is believed that if a pregnant woman has a rounded belly, like a ball, then there will be a girl, if the belly resembles a cucumber, long, then there will be a boy.
- If the pregnant woman felt the first stirring in her stomach on the right, then it is a boy, if on the left, then a girl. This sign comes from the fact that it is believed that the left half of the body is female, the right half is male. So, for example, if you ask a pregnant woman to get up, then you need to observe with which hand she will do it, from here you can draw exactly the same conclusions.
- If the first trimester of pregnancy proceeded easily, it is believed that a boy will be born, otherwise, a girl will be born.
- There is one formula with which you can find out the sex of the child.
How to find out the sex of a child using various fortune-telling
- Grains of barley and wheat should be moistened with pregnant urine. And look, if barley sprouts first, a boy will be born, if wheat - wait for a girl.
- If the expectant mother prefers to start eating bread from the crust, then she will have a son. And if he takes from the middle - a daughter.
- You can ask the expectant mother to take the key from the table. If she takes the round part of the key, then there will be a boy. If a girl is born for a reason.
- If, after a request to show her hands, the pregnant woman shows them with her palms up, then there will be a girl, if down, a boy.
- Hang the wedding ring on a gold chain and hold it over the pregnant belly. If the ring starts to swing back and forth, it means that a girl will be born. If the ring starts to rotate in a circle it will be a boy.
- If you already have a child, then you need to look at the back of his head. If the hair goes down in the form of a pigtail, then the next child will be a girl. If the first word your first baby said was "mom", then expect a daughter. If "dad" - a son will be born.
Determining the sex of a child by heart rate
You can determine the sex of the child with this method at 12-14 weeks of pregnancy. If the fetal heart rate is over 140 beats per minute, then it is a girl. If less than 140 strokes, then a boy.
Special tests to determine the sex of the child
These special tests for determining the sex of the unborn child can help you most likely find out who you will have.
Of course, today there are many methods to determine the sex of a child. But no matter what method you use, the main thing is to let your baby be desired and definitely loved!
Throughout pregnancy, the expectant mother is worried about many questions. One of the most common - who will be born to her, a boy or a girl? Despite the fact that in the 21st century medicine can give an almost 100% answer to this question, future parents do not refuse other methods. How to find out the gender of the unborn child?
Ultrasound examination (ultrasound)
It is much easier for modern mothers to find out the sex of their unborn child precisely because of this miracle of medicine. Starting from the 16th week of pregnancy (and in some cases even earlier), it is possible to determine the sex of the fetus on ultrasound. As a rule, it is confirmed at two screenings (examinations) in the second and third trimesters of pregnancy.
However, this study cannot give a 100% guarantee. Many cases have been recorded when, according to the results of an ultrasound examination, a future mother was “promised” a son, and in the end she gave birth to a lovely daughter - and vice versa. In addition, the fetus can simply simply turn away or close, in a word, take a position in which it is not possible to examine its sexual characteristics.
Be that as it may, future parents do not always trust the results of ultrasound and are looking for other ways to find out the sex of the child.
Ancient Chinese table for determining the sex of a child
The unique table is over 700 years old and was found in a crypt near Beijing. It is believed that determining the sex of the unborn baby using this table gives a probability of 98%. Indeed, often the data matches, and the table gives the correct result.
To determine the sex of a child according to the ancient Chinese table, you need to know exactly the month when the conception occurred. Select your age and month of conception and at the intersection of these indicators you will see the predicted gender of your unborn child.
Blood renewal
This is another fairly common way to find out the sex of a child for free. It is based on the frequency of blood renewal in men and women. For the former, it is updated every 4 years, for the latter - once every 3 years. It is also worth remembering that blood can be "unscheduled" updated during significant blood loss, for example, when donating blood, transfusion, operations, injuries. These points also need to be taken into account.
According to this, it should be calculated when the blood of the future mother and the future father of the child was last renewed. The parent whose blood was renewed later determines the sex of the unborn child by its sex. Those. if the mother’s blood was later renewed, a girl should be expected, and if the father’s, the stork will certainly bring a boy.
Let's give an example of how to find out the sex of the unborn child by the method of updating the blood of the parents. Let's say the future mother is 25 years old, and the future father is 30 years old. It turns out that a woman's blood was renewed a year ago, and a man's - 2 years ago. So this family needs to wait for a girl.
How to find out the sex of the unborn child by the date of conception?
Information about the gender of the child is laid down from the moment of conception. The carrier of this information is the spermatozoon. If the sperm that fertilized the egg is a carrier of the X chromosome, then a girl will be born, and if the XY chromosome, there will be a boy.
How does this relate to the date of conception? The thing is that the sperm carriers of the XY chromosome are much "faster" than the sperm carriers of the X chromosome, but at the same time, the period of their vital activity in the uterus is not so long. Since conception occurs during ovulation, we can assume the following: if the sexual intercourse that led to pregnancy was performed directly on the day of ovulation, then a boy will be born, and if a few days before ovulation, it is worth waiting for a girl.
Determination of the sex of the child by the blood group of the parents
This method is considered imperfect, however, it has the right to exist among others. How to find out the sex of a child for free by blood type and Rh factor of parents? You can use the proposed gender calculation tables:
How to find out the gender of the unborn child using numerology?
It will help determine the sex of the child and the science of numerology. To do this, you need to use the following table:
You need to write the full name of the future mother with the maiden name and the full name of the future father. After that, you need to write in words the name of the month of conception. Convert the letters of names and month names to numbers and add up all the numbers. Divide the amount received by seven. An even number indicates a girl, an odd number indicates a boy.
RIMMA RODONOV: 9 + 1 + 5 + 5 + 1 + 3 + 7 + 5 + 7 + 6 + 7 + 3 + 1 = 60
OLEG RYKOV: 7 + 4 + 6 + 4 + 9 + 2 + 3 + 7 + 3 = 45
MARCH: 5 + 1 + 9 + 2 = 17
60 + 45 + 17 = 122
122: 7 = 17 with the remainder, which is not taken into account.
17 is an odd number, which means that this couple will have a boy.
Folk omens
Of course, in such an important matter as determining the sex of the unborn child, it was not without the participation of folk wisdom. After all, our grandmothers did not know about the ancient Chinese miracle table, nor about the renewal of blood, and ultrasound was completely inaccessible to them. But they also probably knew how to find out the sex of a child by certain signs. Folklore was used, namely, folk signs for determining the sex of a child. What is most interesting is that often these signs turn out to be prophetic. Here are some of them.
You should expect a boy if:
- you do not have toxicosis (do not feel sick in the morning);
- belly low and round like a ball;
- you have cold feet;
- you are drawn to meat and cheese products, as well as salty and sour;
- you are pregnant;
- your nipples have darkened;
- you are worried about headaches;
- eating bread, you prefer the crust;
- you sleep on your left side;
- you are always in high spirits;
- the baby in the tummy is very mobile;
- heart rate of the child is less than 140;
- you are under 20 years old.
You are likely to have a girl if:
- you suffer from toxicosis;
- the abdomen is high and has a sharp (cone-like) shape;
- you are drawn to sweets;
- your left breast is larger than your right;
- pregnancy does not suit you, you look bad, your skin becomes problematic;
- eating bread, you prefer the crumb;
- you sleep on your right side;
- you are nervous and irritated;
- The heart rate of the child is more than 140;
- you are over 30 years old.
divination
There are a number of fortune-telling to determine the sex of the child:
1. A pregnant woman is asked to show her hands. If she stretches them palms up, it’s worth waiting for a girl, and if she holds them palms down, a boy will be born.
2. The expectant mother is asked to take the key lying on the table. If she takes him by the “head” (the round part, the top of the key), a boy will be born, but if by the long part, there will be a girl.
3. A ring is hung on a string and swings over the belly of the expectant mother. If he swings like a pendulum from side to side - expect a boy, and if he drives circles - there will be a girl.
These are all ways to find out the sex of a child for free. We hope you enjoy them.
Life realities do not always coincide with what a person plans for himself, but most people continue to believe that the most important moments of their lives can be subordinated to the plan. And even refusing such a wonderful surprise as the news of the gender of the newborn heir, they are trying to calculate the sex of the child.
There would be nothing reprehensible in this, especially in cases where the question is about the prevention of hereditary pathologies in children of a certain sex. But, unfortunately, they have nothing to do with science and only mislead parents. Let's see what kind of methods these are, how to calculate the sex of a child, all kinds of calendars and tables for calculating the sex of a child are offered, whether they are reliable.
In contact with
Tables for calculating the sex of the child and the so-called pregnancy calendars seem simple and accessible. You can calculate the sex of the child according to the table in a matter of minutes, the main thing is to tune in to intercourse on the very day when the action plan requires it.
Planning the sex of the child is a very difficult question.
Women have been widely using the Chinese method to calculate the sex of a child from a table since about the middle of the last century, when such near-scientific trends as astrology and numerology were on the wave of popularity. The popularity of this technique can be explained by the authority of the state, which gave the world Chinese sages and ancient Chinese medicine, as well as ease of use.
Judge for yourself, for the calculations you need only a couple of accurate data:
- date of conception (only the month, even the date is not necessary);
- the age of the woman at the planned time of the birth of the child.
Anyone who has ever played battleship or simply loved math in elementary school will be able to use the child gender calculation table.
- The top line of the table is a list of the months of conception from January to December.
- The left vertical is the age of the expectant mother.
- At the intersection of a horizontal line with a vertical line, a “forecast” is imprinted - in the form of the letters “M” (boy) or “D” (girl). The method couldn't be easier.
Any sane person understands that predicting, and even more so calculating the sex of a child using a table, is the same as casting lots, the reliability is about the same.
Why is the method of calculating the sex of a child according to the table so popular? Well, extremely dubious theories, therapies and techniques are often overgrown with popularity, as it has always been - both two hundred and a thousand years ago, and even in our sophisticated century.
A little more zaum in another eastern technique - Japanese, using the conception calendar. It is proposed to calculate the sex of the child according to the table.
The theory of blood renewal is deeply unscientific, since the composition of human blood is updated much faster than the stated 3 years for women and 4 years for men.
Nevertheless, the table exists, and it is possible to familiarize yourself with it:
- The upper horizontal column is the full age of the father at the time of conception (from 18 years old).
- The left vertical column is the full age of the mother at the time of conception.
- At the intersection of the lines, as in the Chinese table, there are letters that determine the gender of the unborn baby.
Example: if the father is 30 years old and the mother is 25, then according to the table, they will have a girl. How to calculate the gender of the baby if they need a boy? Let's look at the table:
- a year later (when the father is 31 and the mother is 26), the table again predicts the birth of a girl;
- after 2 years - the table depicts a riddle in the form of M / D, that is, the sex of the child can be any with the same probability;
- finally, only after 3 years (when the father is 33, and the mother is 28), the table promises the coveted "M".
It looks like a Japanese table for determining the sex of a child
Do you really have to wait that long? No, supporters of the idea of blood renewal explain that the results of this technique may vary, depending on which month conception occurs. For example, the father is still 30 years old, and the mother turns 26 years old in 3 months, at this moment the table “predicts” the boy, this time can be used to conceive an heir until the father is 31 years old. Given all these nuances, it is proposed to create your own conception calendar.
And not according to the table, but according to the formula? Yes, the theory of blood renewal offers such an option. For example, let's continue the calculations with an already “familiar” couple - he is 30, she is 25 years old.
- Divide the man's age by 4 (30:4=7.5).
- Divide the woman's age by 3 (25:3=8.3).
- Compare results: 7.5< 8,3.
- Whoever has the highest score wins.
In our case, the woman won, which means that the couple will have a girl by the time they reach the age of 30 and 25 full years. As you can see, the data coincided with the predictions of the Japanese table, but there is nothing surprising in this - the table was compiled according to such calculations.
How reliable are these methods?
The reliability of the considered methods is not worth even thinking about. They are no more accurate than a coin toss prediction, and the possible coincidences that 50 percent of married couples can boast of are nothing more than just coincidences. Anyone who knows what affects the sex of the child, how fertilization occurs and will never trust Eastern theories and will not look for a "table to calculate the sex of the child" (the spelling of the searchers is intentionally preserved).
Recall that the sex of a person is laid during fertilization and depends on the set of chromosomes of the sperm, which will be able to penetrate the egg. During penetration, fertilization occurs - the fusion of female and male germ cells into one, called the zygote, which will already have 46 pairs of chromosomes that determine the sex of the conceived child.
Fertilization is possible only after ovulation, and another popular way is associated with the moment of its onset, how to calculate the sex of the child.
What is the basis of the method of planning the sex of the child at the time of conception? In this technique, the main role is given to ovulation, around which all calculations are made, how to calculate the sex of the child.
What is ovulation?
Ovulation is the exit from the ovary of a mature germ cell and its release from the elastic membrane - the follicle.
- Since birth, a woman's ovaries have been inhabited by several million immature eggs of different quality.
- By the time of reproductive age, their number is reduced to several hundred thousand.
- By ovulation, only one or two eggs mature, ready for fertilization.
- The growth of the follicle and the entire ovulatory process are stimulated by the pituitary gland, which produces a special substance - luteinizing hormone. If the production of LH is insufficient, ovulation does not occur and pregnancy cannot occur.
What is the significance of ovulation for the question of how to calculate the sex of a child? The egg only lives for one day. If the cell is not fertilized, it will die, and after 14 days the woman will begin (regula). It is believed that if fertilization is scheduled for the date of ovulation or a day before it, then the first to approach the egg are more efficient spermatozoa containing the Y chromosome, carriers of male genetic material. This is what parents are trying to use, who are interested in how to calculate the sex of the child so that a son is born.
How to calculate the time of ovulation?
If a woman has a regular menstrual cycle, it is not at all difficult to calculate the moment of ovulation - it usually occurs 14 days before the start of the cycle. The first day of the cycle is the day when a woman has bleeding from the vagina, even if they are not too intense. The duration of the discharge is not important, it can be 2 days or 8, the countdown should be from the first day of the regulation.
How do you know if your cycle is regular? You will have to follow the cycle for at least 3 months:
- Mark the first day of your period in the current month.
- Wait until the next regulation starts.
- Count how many days have passed since the previous start of menstruation.
- Count from the beginning of the next menstruation as many days ahead as you counted last time, mark the day on the calendar.
- When the next period (already the third in a row) comes, compare the date of their start with your mark on the calendar - if they came earlier or later than the "planned" period, then your menstrual cycle is irregular. If they came on time, we can assume that it is regular.
How does the cycle go without pregnancy
In general, the regularity of the cycle can be judged by the results of observation for at least a year, since menstruation can spontaneously change its cycle, especially in young girls. If you are sure that your cycle is regular, subtract 14 days from its expected start, this will be the day of ovulation.
How to calculate with an irregular cycle?
It is more difficult to calculate the date of ovulation for women with irregular cycles. In this case, there are several ways to track ovulation:
- use of pharmacy tests;
- basal temperature charting.
With ultrasound control (folliculometry), it is possible to obtain the most accurate data with a prediction accuracy of up to 12 hours. But this technique cannot be called cheap, because in order to obtain evidence of ovulation that has occurred, you will have to undergo not one, but several ultrasound examinations (3-5 procedures).
A pharmacy ovulation test, similar to a pregnancy test and consisting in determining the LH hormone in the female urine (during the ovulatory period, its level rises), will cost less. However, this technique cannot be called accurate, since an increase in the level of luteinizing hormone is sometimes associated not with ovulation, but with gynecological and other pathologies.
This is what an ovulation test looks like
Finally, a technique that does not require any financial investment is the measurement of basal temperature. It is measured in a state of complete rest, so it requires some preparation.
Preparation for calculation
To chart your basal temperature, you will need:
- notepad or notebook;
- dedicated thermometer;
- if the thermometer is not electronic, but mercury, you will also need a watch.
All of the above should be at hand, next to the bed, even the thermometer should be shaken off the previous readings in advance (in the evening). This is necessary to maintain complete rest after sleep, when the temperature will be measured.
At the time of measuring the basal temperature, you should abandon late dinners and, moreover, from “night eaters”, so that at least 8 hours pass from the last meal before the measurement.
Measurement order:
- Measurements should begin on the first day of the menstrual cycle. Waking up, you should, without getting out of bed, take a thermometer and gently insert it into the rectum.
- After 5 minutes, pull out the thermometer and take readings. Record readings in a notebook.
- From the readings, make a graph with the origin in the lower left corner.
The lower horizontal line should be divided into days, and the vertical line into temperature divisions. Each division should correspond to 0.1 degrees, since only 0.4 degrees have diagnostic value in this process. So it is recommended to start the vertical reading from 36.1o C.
A noticeable increase in basal temperature usually manifests itself from 12-14 days (with a 28-day menstrual cycle), if the temperature is kept at an elevated level (+0.4 or +0.5 degrees) for three days, then ovulation has taken place. How to calculate the sex of the child at conception at the time of ovulation?
The principle is this:
- if you want to conceive a boy, intercourse should occur no earlier than a day before ovulation;
- if you need a daughter, you should have sexual intercourse 2-3 days before ovulation.
Nothing complicated. This is not a conception table; certain dates help calculate the sex of the child.
How is the basal temperature chart plotted?
What is the connection, you ask. The fact is that carriers of the male genome, that is, Y-chromosomal spermatozoa, are much more mobile than X-chromosomal, that is, carriers of female genetic material. However, the first live only 24 hours, and the second - as much as 72. So it turns out that by the time of ovulation, only those spermatozoa that are carriers of the desired genome can be present around the egg.
- If sexual intercourse takes place on the day of ovulation or the day before it, then the nimble Y-chromosomes will be the first to reach the mature reproductive cell of a woman.
- If sexual intercourse occurred 2-3 days before ovulation, then the Y-chromosomes will already die by the time of fertilization, and only X-chromosomes will remain.
Nothing complicated, but there is nothing scientifically confirmed in this theory, how to calculate the sex of the child. The table is 100 percent as likely to justify the forecast as the ovulation counting method.
Is it possible to calculate the gender of the unborn baby by 100%?
Anticipating the disappointment of future parents, who realized that it would not work, let's try to offer the most desperate option. True, you can use it only for a lot of money and strictly for medical reasons.
We are talking about in vitro fertilization, or IVF procedure, combined with preimplantation genotyping (ICSI method):
- The procedure with ICSI assisted reproductive technology does not involve calculations, it is designed for people with sperm quality disorders and other sexual abnormalities.
- The procedure uses paternal sperm (ejaculate), in which, despite complex forms of infertility, morphologically healthy semen can be isolated.
- Fertilization of selected germ cells occurs in vitro, that is, in a test tube, which allows you to check the zygotes for the presence of hereditary diseases and gender.
- Having chosen the highest quality embryo, it is implanted intracervically into the future mother (that is, it is inserted through the cervical canal located between the uterine cavity and its cervix).
Nothing can interfere with the gender of the finished embryo, therefore the IVF + ICSI method is 100% gender planning, but not its calculation.
Conclusion
- Unfortunately, the search for methods on how to calculate the sex of a child according to the table is completely useless, the predictions of the tables are not scientifically substantiated.
- You should not place special hopes on calculating the moment of ovulation, few people succeed in programming the fertilization of an egg with a certain spermatozoon, this process is subject only to chance.
As soon as a woman finds out about a long-awaited pregnancy, she immediately has many questions, one of which ishow to find out the sex of the unborn child? Today, many new ways to study expectant mothers have appeared, but the question of how to determine the sex of a child in the first weeks (or even in the first days) of pregnancy remains open.
Which of them are considered the most effective and what are they based on?
How is a child of a certain gender formed?
To answer this question, you have to remember the school biology course. A woman's egg carries the X chromosome, and male spermatozoa carry X or Y. If the egg is fertilized by the Y chromosome, then in due time the couple will have a boy, and if X, a girl can be expected.
It is difficult to predict this natural process in advance, calculate the sex of the child or influence it in any way, therefore, in the first weeks after conception, determining the sex of the child remains a mystery to both future parents and doctors.
What affects the gender of the baby?
There are many theories about the influence of various factors on the formation of the sex of the child, but so far none of them has found 100% confirmation. For example, there is a statement that the future sex of the child depends on the weight of the mother and her nutrition.
According to some studies, women who weigh less than 54 kilograms are more likely to give birth to girls, and fatter women mostly have boys. Indeed, the development of the male body requires a little more nutrients than the female, but the weight of the expectant mother still cannot be a guarantee of the birth of a child of a certain gender - there are a lot of cases when small, fragile girls successfully give birth to boys.
The same applies to theories regarding the age of future parents: hormonal changes that occur in the human body over the years can affect the sex of the embryo, but are not a determining factor.
Other studies say thatcalculate the sex of the babycan be done with a specific diet. So, in order to give birth to a girl, expectant mothers need magnesium and calcium, that is, eggs, onions, dairy products, nuts, etc. But you can “order” a boy with the help of products such as fish, meat, legumes and fruits - that is, those that contain sodium and potassium.
In addition, acidic foods and drinks (in particular, natural fruit juices without sugar) are considered quite effective in planning the sex of a future baby: nutritionists advise women who want to conceive a girl to regularly use them immediately before conception. This fact has a completely scientific justification - thanks to acidic foods, the environment in the vagina also becomes acidic, which is why spermatozoa with the Y chromosome quickly die.
But in any case, the fundamental role inplanning the sex of the unborn childonly Mother Nature plays, and future parents are unable to influence her decision. The only thing they can do is try to determine the sex of the child before birth, using existing methods and techniques for this.
Methods for determining the sex of the baby
Ultrasound is considered the most accessible way to determine the sex of a child today, but the problem is that this can only be done at a specific time (approximately after the 16-17th week of pregnancy). But what to do if for some reason it needs to be recognized earlier? It is practically impossible to do this in advance with a 100% probability today, so scientists do not leave attempts to find a technique that will allow not only to calculate the sex of the child immediately after conception, but also to plan it in advance.
The most popular and effective are severaltests to determine the sex of the child, which are based on different factors: the blood of the parents, the date of conception and special tables (Japanese and Chinese). You can test each of them in practice and make sure of their reliability below.
Determination of the sex of the child by blood renewal
Ways to determine the sex of a child by the blood of the parents have been known to scientists for a long time, and one of them is based on the date of blood renewal. There is an opinion that a complete renewal of blood, mucous membranes and tissues regularly occurs in the body of each person, and in men the frequency of this process is four years, and in women of the opposite sex - three. That is, if at the time of conception the woman’s blood is “younger” than the man’s, the couple will have a girl, and if vice versa, then a boy.
It is rather difficult to say anything about the reliability of this method, since according to some data it “works” in 80% of cases, and according to others - in 50%. But experts say that if the calculations are made correctly, the couple has every chance of getting an answer to their question with a fairly high probability.
To calculategender of the child by blood renewalyou need to know the date of conception of the baby, as well as the dates of birth of the future father and mother. However, it is important to remember that there are many factors that can speed up the process of blood renewal: these include transfusions, operations, major blood loss or donation. In this case, the countdown should start not from the date of birth, but from the day when the last major blood loss occurred.
Determination of the sex of the child by the blood group of the parents
The method is based on the theory that the blood types of the future father and mother have a great influence on the formation of the sex of the baby. In other words, a woman and a man with certain blood types are more likely to have a child of a certain gender. Of course, this method has the right to exist, but its reliability is subject to great criticism.
The problem is that the table for determining the sex of a child by blood implies one result for one pair of parents, but after all, each of us knows cases when children of different sexes grow up in one family.
Determination of the sex of the child by the Rh factor of the parents
To determine the sex of the baby in this way, it is enough to compare the Rh factors of his parents. It’s easier than ever to do this: if the rhesus match, then the couple will have a girl, and if the indicators are different, a boy.
True, as in the case of the calculation of sex by blood type, the reliability of the result can be strongly doubted, because he claims that a particular couple can have either one boy or one girl.
Determination of the sex of the child according to the Chinese table
This technique does not have any scientific justification, and it is based on the observations and practical experience of several generations of Chinese at once. He says that a woman at a certain age can conceive or give birth to a boy or a girl only in certain months of the year.
According to researchers, the first mention of the method dates back to the 12th century, anddetermining the sex of the child according to the tablehelped many monarchs from the Celestial Empire to plan the gender of their heirs. Howfind out the sex of the child according to the table?
Very simple - you need to know the month of birth of the expectant mother, as well as the month of conception or the expected birth of the baby. By the way, modern parents also talk about its high efficiency of the Chinese table - according to the estimates of couples who used this method, the probability of getting the correct result is about 90%.
To determine the sex of the expected baby according to the Chinese table, simply find the corresponding cell in the table - the intersection of the line of your age and the column - the month of conception.
Interestingly, with the help of this table, you can also plan the gender of the child. In the row corresponding to your age, select the months in which the appearance of a boy or a girl is most likely. Subtract 9 months from the selected month, and you will get the estimated month of conception.

Determination of the sex of the child according to the Japanese table
Determining the sex of a child according to the Japanese calendar, which came to us from the Land of the Rising Sun, is very similar to the definition according to the Chinese table, and is also based solely on practical observations. The difference between them is that the first takes into account not only information about the mother and the month of conception (or the expected month of the birth of the child), but also the date of birth of the father. Thus, the Chinese methodology can be called more flexible and, accordingly, more reliable.
The only problem that some couples may face is the difficulty in determining the month of conception. For example, if a woman ovulated on the 31st, then conception is highly likely to occur on the 1st and 2nd of the next month, because the life of spermatozoa is from 3 to 5 days. The accuracy of the method according to various data is from 70 to 90%.
To determine the sex of the unborn child according to the Japanese table, you need to find the number corresponding to your couple in table 1. Then we find this number in the top row of table 2. In the column of the corresponding number we find the month in which the conception occurred. Moving along this line to the middle of the table, we determine the probability of having a boy or a girl by the number of crosses - the more there are, the greater the probability.

Determination of the sex of the child by the date of ovulation or the date of conception
Every woman knows that conception can only occur on certain days of the month: on average, these are two days before ovulation, ovulation itself and two days after it. A technique that allowscalculate the sex of the child by the date of conception(more precisely, the date of ovulation), is based on the "behavior" and features of the X and Y chromosomes.
According to studies, “girlish” spermatozoa (that is, carriers of the X chromosome) are rather slow, but at the same time more tenacious, so they can stay in the uterus from 2 to 4 days and calmly “wait” for ovulation. But spermatozoa with the Y sign, on the contrary, are very mobile, but their lifespan is very short.
That is, if sexual intercourse occurred 2-4 days before ovulation, then there is a high probability that the couple will have a girl, and if exactly on the day of ovulation (or immediately after it), a boy can be expected.
Method for determining the sex of the child Freiman-Dobrotin
Quite a complicated calculation. But it is considered one of the most accurate. It's good that we have a calculator)
Tables: O - father and M - mother
First, in table O1, we find the intersection of the year of birth of the father and the year of conception of the child, remember or write the number into the intersection.
And so on all the tables from the first to the fifth number.
Then we skaldivat the received numbers and according to the table O6 we find the final coefficient.
Similarly, we do all the actions for the mother according to tables M1-M6
In the end, we look at who has a higher final coefficient, if mom has a girl, if dad has a boy. If both are equal to zero - there will be a girl

Determining the sex of a child using the Budyansky method
Calculation method:
1. If you use the mother's date of birth in the calculations, then you need to determine her approximate date of conception. To do this, subtract 9 months (approximately 226 days) from the mother's date of birth.
Next, you need to determine the even year of the mother's conception or odd.
Next, in the table, find the type of mother's cycle: in the first column, look for a suitable month for the mother's conception, and look for an intersection with the type of year (even or odd) - at the intersection will be the type of mother's cycle.
2. According to the preliminary date of conception of the child, do the same actions as the mother. Determine the parity of the year of conception of the child, look in the first column for a suitable date range in which conception is planned and at the intersection of the type of year of conception and the date of conception, the type of the child's cycle will be indicated.
If the cycle type of the mother and the type of the child's cycle are the same, then there will be a girl, if they differ, then there will be a boy.

Is it possible to predict the sex of a child with 100% probability?
Unfortunately, none of the methods listed above can give a 100% accurate result. Even specialists in ultrasound diagnostics sometimes make mistakes: for example, the fetus can turn so that it will be very problematic to determine the sex of the child.
In addition, until the 18th week of pregnancy, the male and female genital organs are very similar, so even an experienced doctor can confuse them.
There are only two ways to find out exactly the gender of the child:
- ECO. When conducting in vitro (artificial) fertilization, doctors usually determine the sex of the embryo before transplanting it into the uterus. But doing such a study only at the request of parents in most countries is considered unethical, so it is carried out only in order to exclude genetic pathologies that are characteristic of men and women.
- Intrauterine Tests. Most often, they include amniocentesis and chorionic villus sampling and are performed between the 15-18th and 11-14th weeks of pregnancy, respectively. But since these tests carry some risk, they are also carried out only in
To determine the sex of the unborn child, it is not necessary to wait 9 months - you can use one of the sex determination methods that have been tested by more than one generation and are described in this article.
In anticipation of the birth of a small miracle, young parents burn with impatience and want to find out as soon as possible what their child will be like, who is more like, and most importantly - what gender will the baby be. Of course, you can be patient and wait for the ultrasound, which will dot the "i", or you can use numerous methods baby gender calculation and know for sure.
Is it possible to calculate the sex of a child from the blood of the parents?
On the Internet, information is widespread that the sex of the unborn child can be established if you know blood type of both parents. In accordance with this theory, when certain blood types are mixed, a fetus of a certain sex should be formed. The following will help in calculating the gender using this method. table:
Determination of sex by blood type of parents
How to calculate the sex of the child by updating the blood of the parents?
Also quite common method of calculating gender for blood renewal. According to this method, there are certain blood renewal cycles, which are committed in men after 3 years, and for women 4 .
Thus, by dividing the age of the parents by the number of blood renewal, one can determine which of them has the newest blood. Whose newer blood, which means that that gender will “inherit” the baby. In calculations it looks like this:
Blood renewal If mom 28 years, That:
28:4= 7
- get the number of blood renewal
The calculation for the father of the child will look like this:
If dad 30 years, That:
30:3=10
Because update figure mother has less, which means that her blood is younger, and therefore the child will have female.
How to calculate the gender of the child according to the table?
There is no scientific evidence whether using the famous Chinese table you can determine the sex of the unborn child. Legend tells that she was found in the tomb of one ancient emperor and, according to legend, compiled by the sages in accordance with the phases lunar calendar.
The table was found in the tomb of a Chinese emperor. Was it really so or is it just a beautiful myth, but table is actively used and according to the reviews of many mothers, the data in it is completely reliable.
