Calculate the sex of the child using the table. How to calculate the gender of the unborn child based on the date of conception and how accurate are such calculations? Dependence of the sex of the unborn child on the Rh factor of the parents' blood

Various online resources offer expectant mothers a variety of methods for planning pregnancy. In particular, a popular method allows one to find out the sex of a child by the date of birth of the parents. According to the authors, it is advisable to carry out the calculation both in preparation for pregnancy and after conception.

The undoubted advantages of the technique include its simplicity. However, the accuracy of her forecast has been questioned. How to find out the sex of a child by the date of birth of the father and mother, whether this calculation should be trusted and how to find out one hundred percent the sex of the baby, we will consider further.

Classmates

Since time immemorial, humanity has sought to look into the future with the help of numerology. Followers of this discipline believe that human life is closely connected with the magic of numbers. However, numerology refers to esoteric teachings, which means it has no scientific basis.

If in the distant past such calculations were, perhaps, the only way to plan a pregnancy, then at the present stage they have been replaced by ultrasound. With its use, you can already get an accurate answer about who will be born.

Young mothers and fathers most often strive to get ahead of events by turning to articles on how to find out the sex of a child by the date of birth of the father and mother. The technique originated in China many centuries ago. In this country, numerology was one of the highly revered teachings.

You can calculate the sex of a child based on the date of birth of the parents using the following algorithm:

1. Prepare everything you need. To record the initial data, you need to prepare a place for recording and stationery in a contrasting color. For clarity, it is convenient to use blue and pink shades.
2. Build a graph. Before you find out the gender of the child by the age of the parents, it is necessary to draw a diagram based on a straight line. It should be divided into equal segments corresponding to calendar months by name and number
3. Set starting points. Mark the month of birth of the mother with one color (pink), and the month of the father with another (blue). You can also use one color, but the result will not be so clear.
4. Get the result. A simple calculation will allow you to find out the sex of the child by the date of birth of the parents. It is necessary to place points at 3, 6 and 9 intervals after the birth of the mother. Also mark the points 4 and 6 intervals after the month of appearance on the father’s account.

The schedule can be continued, increasing the time coverage. The months located between the pink and blue dots (from left to right), according to the creators of the method, are favorable for conceiving a girl. Periods in the blue to pink dot range increase the likelihood of having a male baby. When located between points of the same color, the sex of the child cannot be calculated based on the age of the mother and father.

Many sites, with information on how to find out the gender of a child by the age of the parents (calculator by date of birth), offer automatic calculations. It is necessary to enter the dates of birth of parents in the windows and the system will independently perform all the calculations.

How to determine by date of conception ()?

There is such a popular theory as calculating pregnancy by renewing the blood of the parents. It is based on the assertion that the representatives of the fair sex undergo a complete renewal over the course of those years. The process takes fathers one year longer. It is the spouse who at the time of fertilization had more “fresh” blood that supposedly influences who will appear in the family.

You can find out the sex of a child based on the date of conception and the age of the parents using a simple mathematical calculation:

1. Write down the year of birth of both spouses on a separate sheet of paper.
2. Calculate the period for a woman. To do this, you need to add three to the year of her birth.
3. Carry out the calculation with your father. To do this, they resort to a calculation similar to the female one, but the number 4 is added.

Let's look at an example of how to determine the gender of a child based on the date of conception and the age of the parents. As initial data, we take the year of birth of the mother as 1992, the father as 1989. We add 3 years to 1992, getting the years of “young” blood for the girl: 2016, 2019, etc. For the father, we add 4, resulting in 2017, 2021, etc. etc.

Table 1. Chromosome combinations that determine gender

The only factor that has a real influence is the combination of chromosomes. The birth of a boy or a girl directly depends on which chromosome, X or Y, was contained in the male reproductive cell - the sperm.

Is there a 100% method for determining the birth month of parents?

At the moment, the only way to plan for a boy or a girl is in vitro fertilization. This technology allows you to combine two gametes in a test tube.

After the fusion of the sperm and egg, the resulting zygote is placed in an incubator for 3-5 days and then implanted in the uterus. As part of the procedure, it is possible to select sperm containing only Y chromosomes. Of course, this technology has nothing to do with how to determine who will be born based on the age of the parents.

If pregnancy has already occurred, you will have to be patient. The reproductive system of the embryo begins to develop around the fifth week. After the eighth, the process becomes active, and by the eleventh the development of the genitals will begin. They can be differentiated around the fourteenth week, which the “one hundred percent” table of conception of the sex of the child by the age of the mother and father is silent about. Used for determination. It is completely safe for the health of the mother and the developing fetus.

Finding out the sex of the child using a table based on the date of birth is an understandable desire. The technique can well be used as entertainment. There is no point in relying on its results, drawing any conclusions or making plans for the future.

Of course, there are people who have obtained reliable results using the method on how to find out the gender by the date of birth of the parents. However, this is quite understandable. The coincidence is explained by the theory of probability. Finding out the sex of a child using a table and the ages of the mother and father is the same as getting the result from fortune telling using coffee grounds or tossing a coin. Sooner or later it will indeed coincide. Trying to find out the gender of the child using the parents' age chart is a waste of time.

Conclusion

1. Recommendations on how to find out the gender of a child by the year of birth of the parents, the table and calculation method have no scientific basis and are supported only by superstition.
2. You should not believe everyone who pushes information on how to find out the sex of a child by the date of birth of the parents or. Such proposals are either quackery or incompetence.
3. It is better to be patient and who will certainly tell who will appear in a happy family.

Boy or girl? Who will be born who will delight their parents with their smile and ringing laughter? The answer to this question worries both expectant mothers and those who are just planning a pregnancy. Is it possible to calculate the sex of a child knowing the date of conception and the woman’s age?

Chinese table for determining the gender of a child

Modern medicine has not gone too far in matters of gender determination. All that an obstetrician-gynecologist can offer is to undergo an ultrasound scan at 12-14 weeks. Good equipment makes it possible to determine the sex of the fetus already at the beginning of the second trimester and thereby satisfy the curiosity of future parents.

In recent years, a new method of calculating the sex of a fetus using the mother's blood has gained popularity. The technique is based on identifying the SRY gene in the blood of a pregnant woman. This gene is found only in male fetuses, and therefore reliably indicates the birth of a boy. The absence of the SRY gene in the mother's blood most likely indicates the female sex of the fetus. The test can be performed as early as 9 weeks of pregnancy.

Traditional Eastern medicine practices slightly different approaches to determining the sex of a child. From ancient times, tables have come down to us, according to which experts many centuries ago tried to predict the probability of the birth of a boy or girl for a particular married couple. In traditional Chinese society, the gender of the expected child was of great importance. The family dreamed of an heir who would take over the common cause and provide assistance to their elderly parents. That is why it was important for every married couple to know when there is a high probability of conceiving a boy, and when to expect a girl. What way did the Chinese sages propose to solve this problem?

Eastern experts have developed a table that allows you to calculate the gender of the expected child. The table takes into account two important parameters:

• date of conception;
• mother's age.

The original table was discovered by archaeologists in one of the ancient temples. This document is still kept in the Beijing National Museum. The table is about 1000 years old. Using this table is not difficult, and any modern woman will be able to calculate the gender of her unborn child without any problems.

The numbers from 18 to 45 are located vertically in the table - the age of the expectant mother. Probably, an adapted version of the ancient original table has reached us. It is known that in traditional Chinese society, girls were married much earlier. By the age of 18, an ordinary Chinese woman could already become a mother several times and please her husband with a long-awaited heir.

Horizontally in the table the month of conception of the child is indicated. The first month (January) will be numbered 1, and the last (December) will be numbered 12. Knowing the date of conception and the age of the mother at the time of this event, you can predict the likelihood of a couple having a boy or a girl.

1. The woman's age is 25 years.
2. The month of conceiving a child is March (month No. 3).
3. At the intersection of the number 25 (vertically) and the number 3 (horizontally) we see the letter “M”. According to the table, this woman will give birth to a boy.

How does the Chinese table work?

Modern scientists have still not been able to comprehend the principle of operation of the Chinese table. There is a version that the table was built taking into account the lunar calendar, which was used by the inhabitants of Ancient China. It is possible that in those distant times special research was carried out, on the basis of which this complex algorithm was developed. Someday scientists will be able to solve this riddle, but for now, future parents can only use the ready-made table and hope that the ancient Chinese method will not fail.

Classical medicine does not recognize the Chinese method of determining the sex of a child. Modern doctors claim that the sex of the unborn baby depends solely on which sperm reaches the egg first. If the quick sperm contains a Y chromosome, a boy will be born. The X chromosome will allow the birth of a girl. This process can be influenced in any way only through IVF (in vitro fertilization). Under natural conditions, it is almost impossible to predict the sex of a child.

How to find out the date of conception?

For women just planning a pregnancy, it will not be difficult to use the ancient Chinese table. All you need is to find the optimal time at the intersection of lines to conceive a boy or girl and pay attention to your spouse at the indicated time. According to the table, intimacy in the selected month will allow you to conceive a child of a certain gender.

Pregnant women also want to know the sex of their unborn child. Not all expectant mothers have the patience to wait for an ultrasound and find out who has settled in the tummy. A Chinese chart will also help you find out the sex of your baby in the early stages of pregnancy. But in order to use it, you need to know the exact time of conception of the child. How to calculate this date?

Calculation of the date of conception with a regular cycle

A woman's menstrual cycle consists of two phases: follicular and luteal. With a regular cycle, menstruation always comes at the same time (± 2 days). The second phase of the cycle always lasts 14 days (± 1 day), while the length of the first phase can vary.

Conception of a child always occurs at the moment of ovulation of the egg or within 24 hours after its release from the ovary. In order to find out the date of ovulation, you need:

• subtract 14 days from the total duration of the cycle (in days);
• add the resulting number to the date of the last menstruation (LMP);;
• the final date will be the day of expected ovulation and conception of the child.;

Pregnancy, especially a long-awaited one, is a bright event in every family. And only after seeing 2 stripes on the test, the couple becomes curious about who they will have - a boy or a girl. This issue is of greatest concern to couples who already have one child or several same-sex children.

It is no secret that determining the sex of the unborn child is possible only at 18-20 weeks of pregnancy during an ultrasound scan. And for some, it’s not easy to wait that long. Here techniques come to the rescue (ancient Chinese table; renewal of the blood of parents; date of conception; fetal heartbeat and others), with the help of which parents can find out the sex of the unborn baby. However, until now, no physician considers these methods reliable. From a medical point of view, this is comparable to fortune telling using coffee grounds. Only medical methods (genetic studies, ultrasound) make it possible to most accurately determine whether a couple is expecting a boy or a girl.

So, in this article we will look at how to determine who will be born - a boy or a girl.

Genetic research

These include amniocentesis, cordocentesis, and chorionic villus biopsy. They are prescribed exclusively for medical reasons to identify genetic diseases or fetal malformations. They allow you to determine the sex of the child with 99% probability. Such an intervention can cause miscarriage or premature birth, because the material (amniotic fluid, chorionic villi, umbilical cord blood) for research is taken from the uterine cavity

Determine the sex of the fetus by ultrasound

Gender can be determined using ultrasound as early as 16 weeks. But more reliable information can be obtained only at 20-25 weeks of pregnancy. In some cases, a specialist cannot see the gender on an ultrasound, for example, the fetus is in an awkward angle or its genitals are covered by the umbilical cord.

Ultrasound is considered the most effective and safe way to find out the gender of the unborn child. Confidence is 95%.

Gender by date of conception

It is known that conception occurs during ovulation (the release of a mature egg from the follicle into the fallopian tube to meet the sperm). The sex of the baby is determined at the moment of conception. If sexual intercourse took place on the day of ovulation, then sperm carrying male chromosomes will reach the egg faster - which means it will be a boy. If sexual intercourse occurred a few days before ovulation, then fertilization of the egg will occur with the hardiest sperm carrying the female chromosome (as a rule, sperm with male chromosomes will have already died by this time). Thus, knowing the day of ovulation and the day of conception, you can estimate who will be born.

Determination by parental blood

A popular technique is to determine the sex of a child by renewing the blood of the parents. The reliability of the method is 50% - it either guesses the gender or not. Therefore, the method is more suitable as entertainment.

Blood renewal theory

There is an assumption that the sex of the child is influenced by the blood of the parents. Every person has blood renewal in their body throughout their entire life. In women, the blood is renewed once every three years, in men - once every four years. And which of the parents has “fresher” blood at the time of conception will have a baby of that gender. However, early renewal of blood is also possible if blood loss exceeds 1000 ml, for example, during surgery, previous difficult childbirth, blood donation (donation), abortion. Therefore, these factors are also taken into account in the calculation.

How to calculate gender based on parental blood renewal

The scheme for calculating the sex of the baby is simple. Let's assume that the future father is 29 years old, and the mother is 23. Next, simple arithmetic operations are carried out: the woman's age is divided by 3, and the man's by 4 (23: 3 = 7.7; 29: 4 = 7.3). As can be seen from the example, the father’s remainder is 0.3, and the mother’s is 0.7, and since 3.7, the couple will most likely give birth to a boy.

If after calculations the remainders are the same, then the couple can have either a girl or a boy.

We offer to determine the sex of the baby using an online calculator. It is enough to enter the date of birth of the parents and know the exact time of conception.

If a man or woman has had blood donation, surgery, or childbirth, then instead of the date of birth, the date of the last blood loss is indicated.

(calculation will take a few seconds)

Determine sex by fetal heartbeat

This technique is based on the assertion that the number of heartbeats is different in boys and girls. Before ultrasound machines, many gynecologists could use a stethoscope to determine gender by heartbeat. Gynecologists have noticed that the heart of girls beats faster - 150 or more beats per minute, and the heart of boys - in the range of 120-140. However, this technique has not been proven, because the heartbeat can be influenced by many factors, for example, excessive activity of the fetus, possible hypoxia, uterine tone, gestational age, time of day, increased blood pressure in the mother.

According to the Chinese calendar

It is possible to find out the sex of a child using the ancient Chinese calendar, which is more than 700 years old. The Chinese believe that its accuracy is very high. It was by this method that in ancient times they determined who would be born to a couple. The method is based on the relationship between a woman’s lunar age at the time of conception and the month in which it occurred.

It is customary for the Chinese to count age not from the date of birth, but from conception. It turns out that Chinese babies are born at 9 months (months of intrauterine stay are added). But, if the baby was born in January or February, then it may be necessary to add another year to his age, in addition to 9 months. The fact is that during this period the Chinese celebrate New Year.

• If she was born after February 23, then 9 months of intrauterine life are added to her age (rounded up to 1 year).
• If from January 1 to January 21, then 2 years will need to be added to the age (i.e. 9 months + 1 year).
• If the date of birth fell in the period from January 21 to February 23, then it is more difficult to calculate the Chinese age. First you need to find out when New Year was in China this year. If a woman was born before him, then 2 years are added, if after - then 1.

To determine the gender of the unborn child using the ancient Chinese table, use an online calculator where you need to indicate the month of conception and the woman’s lunar age.

Scientists have been trying for decades to develop a way to plan the birth of a boy or girl. They managed to find a connection between conceiving a child and the release of an egg and even derive a formula. Determining the sex of a child by the date of ovulation is a scientific, although not very reliable, method.

Online calculator

You can plan the sex of your child based on ovulation using an online calculator. To do this, you need to know the duration of the menstrual cycle and the day your period starts.

This online conception calendar will not only help you calculate the days when fertilization is likely, but will also help you calculate the sex of your unborn child. To calculate the day of ovulation, it is enough to know the date of your last menstruation and the length of your cycle. Fill out the fields of the calculator and click on the “send” button.

You will receive a calendar with the most likely day of ovulation and the days when you need to plan PA to conceive a boy or girl. If conceiving a child of a certain gender is important to you, then it is better to back up the results of the calculator with ovulation tests.

If your cycle fluctuates a little - for example, one month lasts 26 days, another 28 - you need to derive the arithmetic average. For example, if the last three months the duration of the MC was 26,27 and 28 days, then it is better to calculate the ovulation calendar with the number 27. If the cycle fluctuates, then the calculation method will not suit you. It is better to use ovulation tests or do an ultrasound.

Planning a boy or girl by ovulation: the essence of the method

Only those women who have regular menstrual bleeding and whose body does not malfunction can plan the sex of a child based on ovulation (with or without a calculator). The technique is not suitable for girls with a “jumping” cycle and hormonal disorders. It does not work for women who have recently stopped taking hormonal contraceptives; their cycle can take up to 3 months to recover.

To know how to calculate the gender of a child based on ovulation, you need to understand the mechanism of conception. To achieve pregnancy, two sex cells fuse in a woman’s body, each containing 23 chromosomes. Male and female gametes have the same number of chromosomes. When they unite, they form a zygote with a set of 46 chromosomes.

The sperm and egg carry equal genetic material, but the sex of the unborn baby depends solely on the man. Each sperm has an individual chromosome X (girl) or Y (boy). Scientific studies have shown that cells with Y chromosomes move rapidly and are ahead of gametes with X chromosomes. However, the latter have greater viability and can wait for the right moment for several days before ovulation.

Embryologists give male cells the following characteristics:

• A sperm that carries an X chromosome can fertilize an egg after a long stay in the female genital tract. Such gametes do not move forward very quickly. They are significantly inferior to their competitors with Y chromosomes (boys). Sperm compensate for their slowness with high viability. The period of preservation of vital activity is from 3 to 5 days. If fertilization takes place, the woman will have a girl.
• The male reproductive cell, which carries the Y chromosome (boy), is ready for fertilization immediately after intimacy. These sperm move in a straight line and have a high speed of movement. In just a few hours after ejaculation, they can reach their goal, ahead of the carriers of the X chromosome. Fast and playful sperm soon lose their strength and die. The period of preservation of the activity of such cells is no more than a day. If fertilization takes place, the couple will have a boy.

The essence of the method of planning a boy or girl on the day of ovulation is to choose the right time for sexual intercourse. The closer to the peak of fertility you have unprotected intimacy, the greater the likelihood of giving birth to a male child.

If conception occurs on the day of ovulation, a woman has a greater chance of becoming pregnant with a boy. If you are close 3-4 days before the egg is released, the likelihood of having a girl increases.

• If you refuse intimacy 2-3 days before ovulation or use a condom. Unprotected sexual intercourse should take place no earlier than one day before the release of the egg from the ovary.
• If you have unprotected sex several days before ovulation. Within 24 hours before the follicle ruptures, avoid intimacy or use a condom.

Obstetricians and gynecologists consider this method of planning relatively scientific and admit that it works. However, doctors do not advise placing high hopes on him, so as not to be disappointed later. You can try to plan the sex of the child, but you cannot be 100% sure of the result. It is important that there is no failure in the chosen cycle, which will lead to a shift in ovulation and disrupt the plans of the spouses.

How to find out about the release of an egg

Since the time of sexual intercourse, the timing of ovulation and the gender of the child are interconnected, a woman must learn to determine the exact period when the egg is released from the ovary. The length of the break between periods is different for all women, so it is impossible to name a single exact date of ovulation for them. The second phase of the cycle lasts on average two weeks. The easiest way to calculate ovulation requires subtracting 14 days from the total cycle length.

To plan sex based on ovulation, you can use more reliable methods:

• measure basal temperature;
• do tests;
• monitor follicle growth using ultrasound.
• Use our online calculator (a little higher in this article).

Some girls find out about the moment of follicle rupture without additional calculations. They clearly feel ovulation and know in which ovary it occurs.

Other ways to plan the gender of your unborn child

Future parents actively use five methods to determine the gender of the child:

1. Blood renewal. To calculate, you need the year of birth of the future father and mother. Read about how to plan a girl for blood renewal.
2. Blood group. You can determine who will be born to a couple if you know the blood type of each partner. A special table helps you perform the calculation.
3. Rh factor. Calculation by rhesus is performed by analogy with the method of determining sex by group. Often these two methods are used together.
4. Chinese calculation. If you know how old a woman was at the time of conception and in what month it happened, you can plan the sex of the child using the table. The scheme is popular among young couples.
5. . No less often, men and women use the Japanese table. To carry out the calculation, you need to know in what month both partners were born and when conception occurred.

All these methods of determining the sex of a child are not recognized by official medicine, despite the fact that they work for some couples.

There is only one reliable and scientific method that allows you to conceive a child of the desired gender - a boy or a girl. It's called sperm fractionation. This procedure is often used if there are hereditary diseases in the family that are transmitted along a certain line. In this case, it is important for the spouses that they have a child of the opposite sex, who will definitely not inherit a dangerous pathology.

The essence of the sperm fractionation method is that the man's seminal fluid undergoes laser treatment. After this, the sperm are divided into two parts based on chromosome content:

• X chromosomes make it possible to conceive a female child;
• Y chromosomes make it possible to become pregnant with a boy.

Subsequently, fertilization of the egg is performed in vitro with the set of cells that was selected for conception. The sperm fractionation technique is used according to indications; this is one of the stages of IVF. Doctors say that this scheme works effectively, but also does not give a 100% result.

The sex of the child begins to worry future parents, sometimes long before conception. Someone wants a daughter, and someone wants a son. Many do not want to expose themselves to chance, and begin to independently try to plan the sex of the child, using all sorts of options (diet, folk signs, date of conception).

Of course, not everyone plans the gender of their heir before conception. Many people ask this question only during pregnancy. It's too long to wait for an ultrasound, but I really want to solve this mystery as quickly as possible.

Chinese gender determination calendar

We suggest you contact Chinese calendar for determining the gender of a child. The Beijing Institute of Science claims that the reliability of this method reaches 97%.

Using the data from this table:

• If you are planning a child, then in the row of the table corresponding to your age, you need to select the months in which the birth of a boy or girl is most likely, and then subtract 9 months, determining exactly the one in which you should conceive a baby.
• If you are already pregnant, then find in the table the intersection of your age and the month of conception (or the expected month of the birth of the child), and you will find out what gender it will be born.

No logical pattern was found in the table, or it has simply not yet been defined. But oddly enough, in most cases it shows the correct results.

Japanese calendar for determining the gender of a child

Reliable in 80% of cases. This method takes into account not only the date of conception, but also the month of birth of the future parents, and consists of two tables.

Table No. 1 helps you find the “secret” number that connects the month of birth of both parents.

Then in table No. 2 in the top line we find that very cherished number, and in the column below it is the month in which 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 higher the probability).

M- boy

D- girl

Information Baby gender reveal calendars, both Chinese and Japanese, are ideal for planning. These tables are easy to use and are highly likely to offer us their capabilities. However, it must be remembered that the percentage of error still remains. Boy or girl? Who cares! The main thing is to be healthy.
