Boy or girl?

Throughout the history of mankind, people have been trying to guess who will be born to them - a boy or a girl?

Modern medicine offers the most popular way to determine the sex of a baby in the womb using ultrasound. This method gives results from about 16 weeks of pregnancy. But more reliable information can be obtained only at 20-25 weeks of pregnancy. Another way to determine the sex of a child is an American special test, which allows you to find out who the couple is expecting. It is known that fetal sex hormones are present in the urine of a pregnant woman. If you combine it with a special reagent found in the test, it will change color - if it is green, it will be a boy, if orange, it will be a girl. The accuracy of the test is 90%, it can be performed from 8 weeks. However, such a test is not cheap and it will not be easy to find it, since it is not sold in all pharmacies.
If you are just planning to conceive a child and you want a boy or a girl, then with an accuracy of 50% you can use alternative folk and ancient methods of determining gender: according to the Drene Chinese and Japanese tables, according to the renewal of the blood of the mother and father, according to the blood type of the parents, folk signs.

Ancient Chinese table for determining the sex of a child by mother's age and time of conception

Are you planning a child and want to know the gender of your unborn baby? Let's first look at the Chinese fertility chart. The original of this table is kept in a museum in Beijing, its age is about 700 years. A conception table for the sex of a child was discovered in one of the eastern ancient temples. But, according to legend, they initially found it in the tomb of the emperor, and only then transferred it to the temple. The Chinese conception table is based on the fact that the sex of the unborn baby depends on two different factors - the age of the mother and the month of the child’s immediate conception. First find the mother's age, then relate it to the month in which the child was conceived. You will receive a plus or minus sign indicating whether it is a boy or a girl, respectively. This way you can check the birth of yourself or your relatives.

Considering the age of the intended mother, which is indicated in the table from 18 to 45 years, you determine in which month a boy or girl can be born, choose the preferred one and count nine from this month to get the time of conception. Good luck in your endeavors!

Folk signs on how to determine the gender of the unborn child

1. Let the expectant mother take the key from the table (without a ring and not in a bunch!). If she takes the round part, then she will have a boy, if she takes the long narrow part, then she will have a girl, and if she takes the middle part, then she will have twins.
2. If the expectant mother chokes while eating, ask her to name any number. Then figure out which letter of the alphabet this number corresponds to (a - 1, b - 2, etc.) and ask her to name the name starting with this letter. If she chooses a girl's name, then she will have a girl, and if she chooses a boy's name, then she will have a boy.
3. If you have older children, remember the first word of the previous child. If he said “mom” first, then a girl will be born, and if “dad”, then a boy.
4. Compare the year of conception and the age of the mother at the time of conception. If both numbers are even or both are odd, then the birth is a girl, and if one is even and the other is odd, then the birth is a boy.
5. If you want to give birth to a boy, eat more salty foods for several months before conception, and if you want a girl, eat more sweets.
6. If you want to conceive a girl, place a wooden spoon and scissors under the mattress, and a pink bow under the pillow.
7. The gender of the child will be opposite to that of the partner who was more active at the time of conception.
8. If your legs swell during pregnancy, you will have a boy, and if your legs are fine, you will have a girl.
9. If a pregnant woman is irritable, then she will have a girl, and if she is mostly in a good mood, then she will have a boy.
10. If a pregnant woman eats small pieces of bread, then she will have a boy, and if she takes pieces of bread from the middle, then she will have a girl.
11. If a pregnant woman’s hands become dry and the skin on them cracks, then a boy will be born, and if the hands become softer, then a girl will be born.
12. A pregnant woman expecting a boy eats more than one who is expecting a girl.
13. A pregnant, expecting girl feels more nauseous.
14. If acne appears on the face and chest of a pregnant woman, then a girl will be born: the daughter “takes away” her mother’s beauty.
15. A woman who is pregnant with a boy has a lower belly than one who is pregnant with a girl.
16. Thread a chain through the pregnant woman's wedding ring and hang it over her belly (the woman should lie down). If the ring swings back and forth, then a girl will be born, and if in a circle, then a boy. This fortune telling also exists in another version: it is not necessary to hang a ring, but any medallion on a chain, not over the stomach, but over the palm of the pregnant woman, and the results are the opposite: if the medallion moves in a circle, then it is a girl, and if it swings from side to side , then it's a boy. There is, however, an opinion that this fortune telling is only true if the child is not the first.
17. If a pregnant woman is clumsy and constantly stumbles, then she will have a boy, and if she is more graceful, then let her expect a girl.
18. If a boy, already starting to walk, shows interest in a pregnant woman, she will give birth to a girl, and if he does not pay attention to her, then a boy.
19. If a pregnant woman sleeps on her left side, then she will have a boy, and if on her right, then she will have a girl.
20. Ask the pregnant woman to show you her hands: if she turns them palms up, then a girl will be born, if she turns them palms down, then a boy.

Online calculators for calculating the sex of a child

Our calculators for calculating the sex of the unborn child have collected several options and methods; the calculation is based on those methods that have proven themselves among women.

Online calculator for calculating the gender of a child by updating the parents' blood

It is believed that the sex of the child depends on which parent has “fresher” blood. In men, blood is renewed once every 4 years, in women - once every 3 years. So, if dad's last blood update date is later than mom's, then it will be a boy. Try to determine the sex of your baby using this method!

The realities of life 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 a plan. And even refusing such a wonderful surprise as the news about the gender of the newborn heir, they try to calculate the gender 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 these methods are, how to calculate the sex of a child, all kinds of calendars and tables for calculating the sex of a child are offered, and whether they are reliable.

In contact with

Classmates

Tables for calculating the sex of a child and so-called pregnancy calendars seem simple and accessible. You can calculate the sex of a child using 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 gender of a child is a very complex issue.

Women began to widely use the Chinese method to calculate the gender of a child from a table around the middle of the last century, when pseudo-scientific trends such as astrology and numerology became popular. The popularity of this technique can be explained by the authority of the state that gave the world Chinese sages and ancient Chinese medicine, as well as by its ease of use.

Judge for yourself, for the calculations you only need a couple of accurate data:

  • date of conception (month only, not even the date);
  • the age of the woman at the planned time of birth of the child.

Anyone who has ever played “battleship” or simply loved mathematics in elementary school will be able to use the table for calculating the sex of a child.

  1. The top line of the table is a list of months of conceiving a child from January to December.
  2. The left vertical is the age of the expectant mother.
  3. At the intersection of the horizontal line with the vertical line, a “forecast” is imprinted - in the form of the letters “M” (boy) or “D” (girl). The method couldn’t be simpler.

Any sane person understands that predicting, let alone calculating the gender of a child using a table, is the same as casting lots; the reliability is approximately the same.

Why is the method of calculating the gender of a child using a table so popular? Well, extremely dubious theories, therapies and techniques often become popular; this has always been the case - two hundred, a thousand years ago, and even in our sophisticated age.

There is a little more brilliance in another eastern method - Japanese, which uses the conception calendar. It is suggested to calculate the gender of the child using the table.

The theory of blood renewal is deeply unscientific, since the composition of human blood is renewed much faster than the stated 3 years for women and 4 years for men.

Nevertheless, the table exists, and you can familiarize yourself with it:

  1. The upper horizontal column is the full age of the father at the time of conception (from 18 years old).
  2. The left vertical column is the mother's full age at the time of conception.
  3. 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 a child if they want 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 gender of the child can be any with equal probability;
  • finally, only after 3 years (when father is 33 and mother is 28) the table promises the coveted “M”.

This is what the Japanese table for determining the sex of a child looks like

Will we really have to wait that long? No, proponents of the idea of ​​blood renewal explain that the results of this technique may vary depending on the month in which 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” a boy, this time can be used to conceive an heir until the father turns 31 years old. Taking into account 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.

  1. Divide the man's age by 4 (30:4=7.5).
  2. Divide the woman's age by 3 (25:3=8.3).
  3. Let's compare the results: 7.5< 8,3.
  4. Whoever has the higher result “wins.”

In our case, the woman won, which means that the couple will conceive a girl when 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 this is not surprising - the table was compiled according to such calculations.

How reliable are these methods?

You shouldn’t even think about the reliability of the methods discussed. They are no more accurate than the prediction of a tossed coin, 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 a child, how fertilization occurs, and will never trust Eastern theories and will not look for “a table to calculate the sex of a child” (the spelling of the searchers has been preserved intentionally).

Let us remember that a person’s sex is determined during fertilization and depends on the set of chromosomes of the sperm that manages to penetrate the egg. During penetration, fertilization occurs - the fusion of female and male reproductive cells into one whole, called a 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 to calculate the sex of a child is associated with the moment of its occurrence.

What is the method of planning the gender of a child based on the time of conception based on? In this technique, the main role is given to ovulation, around which all calculations are made on how to calculate the sex of a child.

What is ovulation?

Ovulation is the release of a mature germ cell from the ovary and its release from the elastic membrane - the follicle.

  1. Since birth, a woman’s ovaries contain several million immature eggs of different quality.
  2. By the time they reach reproductive age, their number is reduced to several hundred thousand.
  3. By ovulation, only one or two eggs have matured and are ready for fertilization.
  4. The growth of the follicle and the entire ovulatory process are stimulated by the pituitary gland, which produces a special substance - luteinizing hormone. If LH production 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 lives only for one day. If the cell is not fertilized, it will die, and after 14 days the woman will begin to (regulate). It is believed that if you plan fertilization on the date of ovulation or a day before it, then the more efficient sperm containing the Y chromosome, carriers of male gene material, will be the first to approach the egg. This is what parents who are interested in how to calculate the sex of a child so that a son is born are trying to use.

How to calculate the time of ovulation?

If a woman has a regular menstrual cycle, calculating the moment of ovulation is not at all difficult - it usually occurs 14 days before the start of the cycle. The first day of the cycle is the day a woman begins to experience bleeding from the vagina, even if it is not too intense. The duration of the discharge is not important, it can be 2 days or 8, the count should be started from the first day of regulation.

How do you know if your cycle is regular? You will have to monitor your cycle for at least 3 months:

  1. Mark the first day of your period in the current month.
  2. Wait for the next regulation to start.
  3. Count how many days have passed since the previous start of your period.
  4. Count down from the beginning of your next period as many days forward as you counted last time, mark the day on the calendar.
  5. When your next period arrives (this is your third period), compare its start date with your mark on the calendar - if it comes earlier or later than the “scheduled” date, it means your menstrual cycle is irregular. If they arrived on time, we can consider it regular.

How does a 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 cyclicity, 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;
  • charting your basal temperature.

With ultrasound control (folliculometry), it is possible to obtain the most accurate data with a forecast accuracy of up to 12 hours. But this technique cannot be called cheap, because to obtain evidence of ovulation, 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 female urine (its level rises during the ovulatory period), 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 measuring 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;
  • a specially designated thermometer;
  • If the thermometer is not electronic, but mercury, you will also need a watch.

Everything listed above should be at hand, next to the sleeping place, even the thermometer should be shaken off from its previous readings in advance (in the evening). This is necessary to maintain complete rest after sleep, when the temperature will be measured.

During the measurement of basal temperature, you should avoid late dinners and, especially, “night snacks”, so that at least 8 hours pass from the last meal to the time of measurement.

Measurement procedure:

  1. Measurements should begin on the first day of the menstrual cycle. Having woken up, you should, without getting out of bed, take a thermometer and carefully insert it into the rectum.
  2. After 5 minutes, pull out the thermometer and take readings. Write down the readings in a notepad.
  3. 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 count at 36.1o C.

A noticeable increase in basal temperature usually appears from 12-14 days (with a 28-day menstrual cycle); if the temperature remains at an elevated level (+0.4 or +0.5 degrees) for three days, it means ovulation has taken place. How to calculate the sex of a child at conception based on the moment of ovulation?

The principle is this:

  • if you want to conceive a boy, intercourse should occur no earlier than one day before ovulation;
  • if you want a daughter, you should have sexual intercourse 2-3 days before ovulation.

Nothing complicated. This is not a conception table; certain dates help to calculate the gender of the child.

How to build a basal temperature chart

What is the connection, you ask. The fact is that carriers of the male genome, that is, Y-chromosomal sperm, are much more mobile than X-chromosomal sperm, that is, carriers of female gene material. However, the former live only 24 hours, and the latter - as much as 72. So it turns out that by the time of ovulation, only those sperm that are carriers of the desired genome can be present around the egg.

  1. If sexual intercourse occurs on the day of ovulation or the day before it, then the nimble Y-chromosomal ones will be the first to reach the woman’s mature reproductive cell.
  2. If sexual intercourse occurred 2-3 days before ovulation, then the Y chromosomes will have already died by the time of fertilization, and only the X chromosomes will remain.

There is nothing complicated, but there is nothing scientifically proven in this theory on how to calculate the sex of a child. The table has the same 100 percent chance of justifying the forecast as the ovulation calculation method.

Is it possible to calculate the gender of a future baby 100%?

Anticipating the disappointment of future parents who have realized that it will not be possible to calculate, we will try to offer the most desperate option. True, you can only use it for a lot of money and strictly for medical reasons.

We are talking about in vitro fertilization, or the IVF procedure combined with pre-implantation genotyping (ICSI technique):

  1. The ICSI assisted reproductive technology procedure does not involve calculations; it is designed for people with sperm quality disorders and other sexual abnormalities.
  2. The procedure uses the father's sperm (ejaculate), in which, even despite complex forms of infertility, a morphologically healthy seed can be isolated.
  3. Fertilization of selected germ cells occurs in vitro, that is, in a test tube, which makes it possible to test zygotes for the presence of hereditary diseases and gender.
  4. Having selected the highest quality embryo, it is implanted into the expectant mother intracervically (that is, introduced 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

  1. Unfortunately, the search for methods on how to calculate the sex of a child using a table is completely useless; the predictions of the tables are not scientifically substantiated.
  2. You shouldn’t place much hope on calculating the moment of ovulation; few people succeed in programming the fertilization of an egg with a specific sperm; this process is subject solely to chance.

In contact with

Every couple expecting a baby wants to know in advance who they will have. And some go even further and try to plan their birth. Let's consider whether it is possible to determine the sex of a child by the date of conception, and some prediction methods known today.

How to calculate a day for floor planning


Since the mystery of childbirth has concerned people since ancient times, determining the sex of a child by the date of conception exists in every nation. In addition, scientific research in this area is increasingly opening up the problem and offering their own methods for designating days on which there is a high probability of conceiving a son or daughter.

Scientific background

When considering the scientific basis for the issue of embryo conception, it is enough to have a little knowledge of anatomy to agree with their version. The sex of the embryo depends on the chromosomes of the cells that came into contact. Female cells are all endowed with only X chromosomes. This means that they do not affect the sex of the fetus. Male ones are of several types: X and Y. With which of them the female cell interacted and the future sex depends:

  • both X-type cells: girl;
  • female X and male Y: boy.

But can a couple influence their cells and choose the sex of their baby? Today this is possible if we look at the characteristics of sperm, which determine the sex of the unborn child based on the date of conception. Let's consider the main features of Y-type cells:

  • fast, swift, agile;
  • have a short lifespan.

These criteria show that sexual intercourse while the finished cell is in the female tract leads to fertilization by Y-sperm. They will reach the cell much faster than the X cells and fertilize it. If there is no ready-made cell at the moment, Y die very quickly - up to 24 hours. This means that in order to conceive a son, you need to perform the act exactly on the day of ovulation.

X-type cells have the following parameters:

  • slowness, low mobility;
  • high viability.

They are able to survive in a woman’s reproductive environment for up to 3 days. In some cases, even up to 5 days. Thus, in order to predict the birth of a daughter, you need to create the following conditions:

  • Carry out the act when there is no female cage yet.
  • Male Y cells die.
  • A female egg appears.
  • The slow Xs have already advanced and are ready to meet her.
  • There are no Y left in the reproductive tract that can determine the male sex of the embryo.

To recreate a similar situation, it is necessary to perform the act a couple of days before ovulation. At the same time, the main thing is not to repeat it later, so as not to give the Y-cells a chance to “hold out” until the day the cell appears. This is how, using scientific evidence, you can determine the sex of the unborn child by the date of conception:

  • Girl: on the eve of ovulation (2-3 days before);
  • Boy: at the moment the cage comes out.

Detecting the day of ovulation

If you want to use such calculations, then you need to understand the definition of this important moment - ovulation. It's actually quite simple. You can calculate it like this:

  • Determine the cycle duration. To do this, you will need to calculate the number of days between menstruation. In this case, the length of the discharge itself does not play a role; the initial days are taken into account. Typically, the parameter varies within 25-30 days.
  • The cycle varies depending on the maturation period of the follicle and cell. It is unique for everyone and may require 11-16 days. This first phase will not help us. It cannot be calculated.
  • The second part of the cycle is the same for everyone: 14 days. This is exactly how long it will take for the ovaries to “return” to normal and prepare for the production of a new cell.
  • So, we go by the opposite: we subtract 14 days from the first number. The result obtained indicates the number of days that need to be counted from the first day of bleeding. This will be the day of ovulation.

Let's look at calculating the sex of a child based on the date of conception using an example. A woman’s cycle is 27 days, and her last period occurred on the 5th. We make simple calculations: 27-14=13. We count 13 from the 5th. Expected ovulation occurs on the 18th. If the spouses want to conceive a son, the act should be carried out exactly on the 18th, if the girl – on the 16th.

As you can see, everything is simple. But there are cases when mathematical calculation will not be enough. Firstly, a woman may experience a malfunction, due to which the cell will take longer to mature in this particular month, or ovulation simply will not occur. Changes in rhythms can be caused by any reasons that affect hormone levels:

  • stressful situations;
  • infection, disease;
  • taking hormone-containing drugs;
  • travel to a country with a different climate;
  • change of living conditions (vacation).

Therefore, it is better to confirm any calculations with additional means. These can be tests. Today there are many of them and everyone can choose the best option in terms of quality and price. They respond to luteinizing hormone (LH), which peaks 12 hours before the cell appears. There are also more expensive, but reusable devices that can detect the moment of ovulation by the salt content in saliva.

If a woman has irregular periods, calculating the sex of the child based on the date of conception will be very difficult. After all, every month they have different lengths and, accordingly, the cage comes out at different moments. Therefore, they should only roughly calculate the day based on their minimum cycle, and conduct testing to identify it more accurately.

Foods to influence gender

In addition to everything discussed above, scientists who are adherents of this method consider it obligatory to “feed” the desired type of sperm with the microelements they need to increase their vital activity. It is known that:

  • Y-cells require sodium and potassium to function;
  • X cells prefer calcium and magnesium.

Based on this, scientists advise making several changes to your diet in advance of planning a pregnancy. You need to consume more foods with these elements and limit those that contribute to the opposite result.

When planning a daughter, you need to eat seafood, fish, rabbit, chicken, dairy products, eggs, rice, cereals, yeast-free bread, many fruits, vegetables, dried fruits, and legumes.


When planning a son, you need to eat smoked meats, dry sausages, meat products, mushrooms, potatoes, bananas, cherries, apricots, prunes, dates, peas, lentils, egg whites.


But you should change your diet with the consent of your doctor. A child will need many vitamins and minerals for normal development, so you should not deprive them. Therefore, the doctor can prescribe a diet taking into account your expectations. There is no need to be afraid of eating the “wrong” product. At small doses, the amount of “unnecessary” element will not have a harmful effect. The main thing is to observe moderation and slightly increase the consumption of foods rich in an element that helps prolong the life of cells involved in influencing sex.

Online calculator - operating principle

Today, calculators are offered to determine the sex of a child by the date of conception, most often working according to the algorithms described in the first section.

They allow you to enter your characteristics and receive ready-made calendars for the coming months, where the optimal dates for conception will be marked. If you specify a gender prediction, the cells will be colored pink for a higher probability of getting a girl, or lilac for a boy.

Our calendar takes into account the following data for calculation:

  • cycle length;
  • number of days of menstruation;
  • the beginning of the last menstruation;
  • enable gender prediction;
  • for how many months to perform the calculation.

Calculation of the child's gender based on the last two dates of menstruation

There is also a second method of calculation - based on the last two dates of menstruation. It is suitable for women who do not follow rhythms and do not have such information. It is worth considering that in such a situation, a calculator for determining the sex of a child by date of conception will not always give an up-to-date result. This is due to the possibility of a discrepancy between the latest readings and the usual ones that occurred previously.

After checking your parameters, we get the following parameters marked on the calendar:

  • three dates when it is possible to conceive a daughter, the last of which falls one day before the cell’s “birth” day;
  • the day of ovulation, when there is a maximum chance of getting a son;
  • two days, when you can also count on a boy - one day before and the next after leaving the cage.

As you can see, the calculator calculates the gender of the child based on the date of conception, taking into account scientific methods known to us regarding the vital activity of cells with different types of chromosomes. Of course, you need to understand that the act on the eve of ovulation is not always productive. After all, sperm Y may die before the cell exits, and then the opposite result will occur. If you conceive after the cell has appeared, you may not get pregnant at all. This is due to the lifespan of the egg. She lives for about a day, and therefore may die by the time the sperm enter the genital tract.

As for conceiving a daughter, the first date will most likely not bring any effect. After all, X-type sperm will not always be able to last 4 days until a female cell appears. Their lifespan is different for everyone and can reach up to 5 days, but the standard parameter that occurs in most cases is 3 days.

Therefore, even if you receive a forecast for the sex of your child based on the date of conception online, you should not follow it blindly, but take into account your knowledge on this topic.

Chinese calendar for determining the gender of a child

You can also determine the gender of the unborn child using the Chinese calendar. The gender of the child is determined by the date of conception. This technique is very ancient and was used even in Ancient China. It is believed that since then the table has not changed, but was used by women to predict the heir, which is important for the Chinese. They say that even today many Chinese women use this table.

It looks like this:


To use this table, you must follow the instructions:

  • Find the horizontal line corresponding to your age.
  • Months are located in vertical columns. Find the nearest ones.
  • View the forecast for each of them.
  • Choose your option (boy or girl).
  • Record the months when the desired effect is predicted.

The table is easy to use and no additional methods are required. The day of conception is considered the moment of ovulation. To “strengthen” the effect, it is worth combining already known methods of assigning the “right” day with a table.

If we consider the reviews of those who determined the gender of the child by the date of conception, the table does not always show the correct result. In particular, there are forums where mothers checked their data against the children they already had. The coincidence ratio indicates that the table is unreliable in at least 1/3 of the cases.

Adherents of the Chinese theory found an excuse for this. They talk about a different way of counting birthdays among the Chinese. According to Chinese teachings, a person is born in the womb. Therefore, it is the day of conception of the embryo that they recognize as their birthday. That is, to use the table, it is advised to add another 9 months to your years. And often this takes the woman to another line, where other predictions regarding gender are already marked in the fields. But for this method of interpreting the table, there is no verified data to know the effectiveness.

Important

You will have to decide for yourself whether to trust the chart to determine the sex of the child based on the date of conception.

Skeptics, for example, point to the lack of data on the father. But, as is known from scientific research, the sex of the newborn depends on it. In addition, no one has yet been able to scientifically confirm the direct relationship between the mother’s age and the date of conception.

Japanese table for determining the sex of a child

That’s why some people prefer another calculation option – the Japanese table. It includes two interconnected plates. The first one is needed to assign a check number. This figure is determined by the dates of birth of each of the future parents. At the intersection of the months there is a number that corresponds to the pair:


Having found out this number, you need to move on to decoding the second part:


Here you need to follow the instructions:

  • Find your number in the vertical column.
  • Look at the desired column (boy, girl).
  • Find the largest values ​​in the latter.
  • Draw a straight line to the column with your number. The most favorable month is written here.
  • The remaining months can be determined by comparing the parameters for the son and daughter. Choose those where the excess is more significant.

Users like this table more. If the Chinese table reveals the sex of the child based on the date of conception and the woman’s age, then the Japanese table also takes into account the characteristics of the father. But there is also no statistical data regarding its effectiveness.

Blood renewal and rhesus - what medicine says

In addition to the methods listed above, you can turn to medicine. Everyone has heard that the sex of an embryo is predicted by blood type, Rh factor values, or the structure of blood renewal. Although these methods are also not 100% accurate, you should not completely dismiss them.


When planning a child, the couple undergoes some tests. The blood is checked not only to identify abnormalities in health, but also to determine whether the couple’s Rh factors match.

It is no secret that, given certain parameters, it can be difficult to get pregnant even with normal sexual function in each spouse. The situation is considered especially dangerous when a woman has negative Rh. It affects the rejection of male cells, which makes the fertilization process itself and the subsequent stage of attachment of the fertilized egg very difficult. If a mother with such Rhesus develops a fetus with a positive factor, immune complications may even occur.

The forecast itself looks like this:

  • identical rhesus: daughter;
  • different rhesus: son.

Blood table for calculating the sex of the unborn child

So, we have looked at how to determine the sex of the unborn child by the date of conception using calculators and Chinese forecasts. Let's look at how this can be done using a blood table.


Having chosen our characteristics, we get a very likely answer. However, statistics indicate some error. Otherwise, we would not see situations where children of different sexes were born in the same family, which is not at all uncommon.

How blood renewal affects the gender of the child

Another medical scientific method is blood renewal. It is known that the spouse whose blood is “younger” directly determines the sex of the embryo. A woman’s blood rejuvenates somewhat more often – every 3 years. The date of the last update must be determined from the year of birth. If a woman gave birth, received a serious injury, or underwent treatment combined with large blood losses, then the calculation must be carried out from this year. An unscheduled rejuvenation occurred in him. For men, the countdown is similar, but taking into account the frequency - once every 4 years.

Having calculated the criteria, the couple should find out which of them had the blood rejuvenated last. If the father has a boy, then the mother has a daughter.


So, today you can find out the sex of a child by the date of conception using several options, the main ones of which we have considered. The effectiveness of each raises some doubts, except, perhaps, the first – scientifically based. Therefore, no one promises a guaranteed result. But if you combine several, you can quite hope for the desired effect.

The gender of the baby directly depends on whose blood - mom's or dad's - is younger, that is, whose blood was renewed later.

  • By blood type

    You can determine the sex of a child by the combination of the parents' blood groups. Some people think this method is ridiculous, but you can just try it.

  • Ancient Chinese table

    Determines the sex of the unborn child using the age of the mother and the month when the baby is due.

  • Japanese table

    Determines the sex of the unborn child by the month of birth of the mother and father and the month of conception.

    • The sex of the child begins to worry future parents long before conception. Some people want a boy, some want a girl, but most importantly, many do not want to depend on chance, so they try to plan the sex of the child. Diet, folk signs, the sex of the child by date of conception and many other ways to determine the sex of the unborn child are used by parents.

    However, not everyone plans the gender of their baby before conception. Many people begin to worry about the question “how to calculate the gender of a child” when they are already pregnant. In this case, you can find out the gender using an ultrasound, but for this you need to wait, and you really want to find out as quickly as possible, preferably right now.

    For those who want to know how to calculate the sex of a child, the site team offers to take tests to determine the sex of the child. Thanks to these tests, you can calculate the sex of the child by the date of birth of the parents, by the last update of their blood, by blood type and Rh factor. You can also calculate the sex of your unborn child using Japanese and Chinese methods of planning the sex of the child, presented in the form of simple tables. Determining the sex of your unborn child using these methods will allow you to choose the right month to conceive a boy or girl.

    With the help of our service, you can, without fuss and at a time when it is convenient for you, determine the gender of your unborn child for free, using all the tests presented on the site.

    For some women, the question of the sex of the unborn baby will finally become clear at the 20th week of pregnancy after an ultrasound. But if for some reason an ultrasound examination cannot be done, or the child has turned so that it is impossible to see whether it is a boy or a girl, or the parents want to plan the gender of the baby before conception, what to do? And here various kinds of calculators come to the rescue, calendars for determining the sex of the unborn baby, based on the date of the last menstruation.

    Methods for calculating the sex of a child

    The existing methods for determining the gender of a child can be divided into two groups:

    • scientific, that is, approved by doctors (ultrasound, as well as when conducting tests for genetic pathologies, for example, during the amniocentesis procedure);
    • folk, that is, unscientific, proven over the years with more or less success, but not deserving the absolute approval of doctors.

    Sooner or later, all parents are puzzled by the question of who will be born: a boy or a girl.

    Method for predicting the baby's gender based on ovulation in the last cycle

    This method cannot be classified as exclusively folk or amateurish, since it is based on the physiology of the female body, that is, it has a scientific basis. Although you cannot completely trust it as scientific: calculations may have errors associated with the individual characteristics of women’s health. The method is used to calculate the baby’s sex in advance and is based on calculating the timing of ovulation based on the dates of the monthly cycle.

    The table shows the approximate days of the onset of ovulation for monthly cycles of different lengths

    The ovulation technique is based on the fact that conception occurs only at a certain time, and signals about its changes are reflected in the woman’s body (increase in breast volume, pain in the lower abdomen, increased libido, etc.). But you can calculate the date of ovulation based on the timing of the monthly cycle: the release of the egg from the ovary is planned for its middle, plus/minus 2–3 days. For example, with a 28-day monthly cycle, the expected release of the egg will occur on the 14th day, that is, one day of the week after the start of menstruation, and the ovulation period will be from the 11th to the 16th day. The ovulation method is based on the fact that carriers of the “X” chromosomes, that is, girls, are slow, but more persistent, therefore, once in the vagina, they are able to maintain their vitality for up to 3 days (according to some studies - up to 7 days), waiting for ovulation. But the male chromosomes, that is, the X chromosomes, are very nimble, but they do not retain their vitality for very long. Therefore, if sexual intercourse occurs 2-3 days before the release of the egg from the ovary, the advantage will be on the side of the girl, and if it is on the day of ovulation, then the likelihood of adding a boy to the family increases. Thus, to implement this calculation method, it is important to know the date of ovulation, and therefore the start and end dates of menstruation.

    The timing of the last menstruation is important for calculating the date of conception, which is the basis for most methods for early determination of the baby’s sex

    How to determine the day of ovulation in the monthly cycle

    In addition to the mathematical calculation of the ovulation period, there are three more methods that also rely on the start date of the last monthly cycle.

    1. Special tests for ovulation. They can be bought at the pharmacy. They are carried out daily until the appearance of a distinct second stripe, that is, an increase in luteinizing hormone, indicating day X, starting from the date obtained as a result of calculations of the approximate onset of ovulation. To do this, subtract 17 from the average number of days of the cycle, for example, with a 28-day cycle it will be the 11th day, and with a 34-day cycle it will be the 17th day.
    2. Measuring basal temperature. Every morning, a woman measures the temperature in the rectum, vagina or mouth. If in the first half of the cycle the readings are around 37º, during the period of ovulation the temperature drops by 0.3º, and at the time the egg is released it rises again to 37º. If the graph is presented in the form of a bird with open wings, then the day of ovulation is the beak of this “feathered bird”.
    3. Tracking follicle development using ultrasound. Conducted by a doctor in a medical facility.

    How to calculate the baby's gender based on the date of the last menstruation

    As for folk methods of determining the sex of a baby, there are about a dozen different calculators, schemes based on the start and end dates of the last menstruation and determining the date of ovulation, which is considered the date of conception of the baby. One of these is calculating the sex of the child based on the date of the last menstruation. This method is based on the relationship between the woman’s age and the month of her last menstruation. The formula for calculation looks like this: the serial number of the month + the number of complete years of the woman on this date + unit. If the result is an even number, it will be a girl, if it is an odd number, it will be a boy.

    My last menstruation before conception was on May 9, that is, the 5th month, at which time I had already celebrated my 31st birthday. We get: 5 + 31 + 1 = 37. I really have a son.

    Most non-scientific methods for calculating the sex of an unborn child require the date of conception, that is, the day of ovulation

    Table: advantages and disadvantages of determining gender by date of last menstruation

    This is interesting. The Chinese and Japanese, who carefully monitor the demographic situation in their countries and have forced restrictions on the number of children in families, since, starting with the second baby, parents pay a large tax, pay great attention to the choice of the sex of the future baby. Therefore, scientists from Japan are actively developing a theory according to which the gender of the child can be predicted by the age when the expectant mother had her first menstrual bleeding: the earlier this happened, the greater the chance that it will be a girl. So, for example, if menstruation began at 10 years old, then with a 53% probability a little princess will be born, if at 12 years old, then 50/50, and if at 14, then 53% remains on the boy’s side. I fell into the category where the probability of a boy or a girl is determined by 50/50.

    Reviews of the method of calculating gender based on the date of the last menstruation

    Some women with great enthusiasm carried out calculations both for their children and for the children of all their friends and acquaintances:

    Calculation of parental blood renewal

    The technique is based on the fact that human blood is systematically renewed: for women - every 36 months, that is, after three years, for men - every 48 months, that is, after four years. According to calculations, the baby will be born with the gender of the parent whose blood turned out to be “fresh” at the time of fertilization of the egg.

    Instructions:

    1. We add three years to the mother’s year of birth and four to the father’s, up to the year the baby was conceived.
    2. Whose blood is younger by the day of conception, that is, approximately in the middle of the last monthly cycle, will have a baby of that gender.

    You can also enter the initial data (birth dates of parents and conception of the baby) into an online calculator and trust the program.

    Important: if in the life of the parents there were cases associated with blood loss, then the objectivity of the results of calculating the sex of the baby based on blood renewal is reduced.

    One of the methods for determining the sex of the baby is based on the timing of blood renewal in mom and dad, as well as on the date of conception

    Reviews about the technique

    For many families, the method of calculating gender based on the timing of blood renewal gave correct results.

    My mother introduced me to the method of determining the sex of an unborn child using blood renewal. For many years, she has been counting on all her loved ones. And I have never made a mistake. It’s a pity, we were counting on a second daughter)

    Budyansky method

    Another way to calculate who will be born, taking into account the monthly cycle, was developed by the Budiansky teaching spouses, who, based on research by scientists at the American private Johns Hopkins University and an analysis of the biographies of their students, formulated the conclusion that in each cycle the egg secretes a certain substance that attracts The X chromosome (even, “female cycles”), and in certain cases, the Y chromosome (odd, “male cycles”). You can tell who it will be - a girl or a boy, based on the cycle in which conception occurred. The determination of whether a woman’s cycle is even or odd is directly dependent on whether she was conceived in a male or female state. Moreover, if the expectant mother was conceived in an even-numbered month, she can only conceive babies in even-numbered months, and boys in odd-numbered months. And, conversely, if a woman was conceived in an odd month, then she will have princesses in odd months, and princes in even months. To use this method, it is important to know exactly the date of your last period, since it will be used to determine the day the baby was conceived.

    You can find out the sex of your unborn baby using the Budyansky table

    Method for calculating floors for even or odd cycles

    To predict the sex of the baby you will need:


    Instructions:

    1. We start with determining whether a woman is even or odd. From the month of birth we subtract 38 weeks (that is, 8 months). This will be the date the woman is expected to conceive. And again I’m experimenting on myself: I was born on November 10, the approximate date of conception is February 23.
    2. We determine from the table whether the month of the future mother’s conception date is even or odd, focusing on the even or odd number of the year of birth. It's an even month for me.
    3. The conception of my child was in May, the fifth month, that is, odd. So, according to the Budyansky formula, I have a boy - everything is correct.

    For those who prefer to trust online calculators, calculations using the Budyansky method can be done.

    However, for me personally the results were not the same.

    Reviews about the Budyansky method

    As practice shows, the technique cannot say for sure who will be born: a son or a daughter.

    According to this method, I should have two girls, but the youngest is a son!

    I have the same 2 pregnancies.

    It’s all bullshit, it worked out well with my first daughter, but my second daughter is definitely a boy according to all tables! My mother should also have me as a boy, and my brother as a girl!

    I wrote to Budyansky, he counted for me and confirmed that I was even, and my son was odd, and that’s all. If he claims that it is necessary to count according to the last menstruation, then it turns out that I have a girl, but with a real pregnancy he answered that, most likely, there will be a boy, but since the cycle is irregular, 26–28 days, perhaps there will be a girl, as something like that)))) 50/50 in short, point to the sky, as they say))

    Freiman-Dobrotin method

    A method requiring arithmetic calculations using six tables. The technique was proposed by software engineer M. Freiman, who formalized the principle of predicting the sex of a baby, taking it from various folk beliefs on this topic. Professor S. Dobrotin subsequently checked these data at the Gorky Maternity Hospital, and in 99 cases out of 100 the theory was confirmed. Calculations are made for both mother and father. But in both cases, you need to know the period of conception of the child, that is, you cannot do without the date of the last menstruation here.

    Instructions:

    1. We start with calculations for dad. We find in table No. 1 the intersection of the year of his birth and the date of conception of the baby. Write down the number.
    2. Further, for each table we also fix the number at the intersection of two columns.
    3. We add the numbers and get the final coefficient.
    4. We practice the same steps, but for mom. Please note that the data in tables No. 4, 5, 6 for men and women are the same.
    5. We compare the odds: whoever has more “wins”, that is, if dad has a boy, if mom has a girl.

    Calculations can also be made using an online calculator using the Freiman-Dobrotin method.

    According to my spreadsheet calculations, the result coincided with reality: a boy. But according to the online calculator - no, it showed a girl.

    We determine the father’s usual or leap year of birth, as well as how many days are in the month of his birth. We calculate the results for both parents

    Chinese table

    Another way to calculate the sex of a baby is to use a Chinese table found about 700 years ago in one of the temples near Beijing. The principle of its operation does not have any scientific explanation; all data was verified by the centuries-old experience of the inhabitants of the Celestial Empire, because the first use of the method dates back to the 12th century. And since then, many Chinese monarchs have been able to calculate the gender of their heirs. To use the Chinese table, you do not need to perform mathematical calculations.

    Instructions:


    This is interesting. To calculate the sex of the child in advance, we choose who we want: a boy or a girl, and mark all the months where the chances of achieving what we want are highest. These will be the best months to conceive. All that remains is to choose those that also coincide with ovulation.
