METHODS FOR PREDICTING THE GENDER OF A CHILD

Method essence


The calculation of data for determining the sex of a child is based on the cyclical renewal of the blood of men and women, depending on their date of birth. Term blood renewal quite abstract and can be contested, however, it seems to me the most acceptable in this description.
The blood renewal cycles for men and women are different and are strictly defined periods, starting from their birthdays. I will allow myself not to publish this data and refer it to know-how.
Assuming that the state of the blood changes from the maximum - the beginning of the cycle, to the minimum - its end, and combining the data for a man and a woman, one can find a certain relationship and introduce a new term - Strength of blood or Youth of blood characterizing this dependence. It is this parameter that determines the sex of the unborn child - i.e. whose blood is stronger (or younger), that blood prevails, predetermining the sex of the unborn child.
Parameter Strength of blood is strictly tied to dates, which allows, with great accuracy, to calculate the probability of having a child of one gender or another, on any date in the year.

Interpretation of results


In order to correctly use the results obtained, it is necessary to understand in detail what is presented on the graph.
All data located to the right of the vertical line are 50/50 marks (colored in blue color) indicate that the conception of a boy is possible on the corresponding dates. The data located to the left of the 50/50 mark (colored red) are girls.
The probability level (as a percentage) can be estimated by the value shown in each row.

ATTENTION: You must understand correctly that the results located near the 50/50 mark do not allow, with a certain degree of probability, to calculate the sex of the child, because for this period, conception of both a boy and a girl is possible, in approximately equal proportions.

ADVICE: 1. Try to avoid periods where the values ​​are located in the immediate vicinity of the 50/50 mark.
2. Sometimes situations arise when the values ​​have a high level, but the period of this level is insignificant, so there is no guarantee of conceiving a child of the desired sex.
3. For conception, choose a period when the values ​​tend to 100%. For greater likelihood, it is better to shorten the selected period by 2-3 days on each side. By analogy with short-term periods, conception should be avoided at times when meanings change from one state to another.

In conclusion, I would like to say that no matter what, the appearance of a child of any gender in a family is a great and joyful event. Therefore, if the result did not coincide with what you planned, do not despair. Everything is God's will.

Childbirth is a unique process that is not easy to predict. Due to the peculiarities of the work of each organism, the processes can proceed in a peculiar way and cannot be systematized. Nevertheless, many want to plan and anticipate all the nuances, right up to the conception of a baby of a particular gender. Consider how to create your own pregnancy calendar and calculate the sex of the baby using different methods.


Preparing to conceive a child

If there is a clear desire to influence the sex of the embryo, you need to carefully weigh everything, follow the current cycles in the body for several months in order to understand how easy it will be to do it.

To plan the conception of a child (calendar) and calculate the sex of the child, a woman should know the following parameters:

  • Cycle length. It needs to be identified by counting the number of days between the first dates of menstruation. The norm is considered to be 28 days. But a deviation of 5-6 days up / down is also acceptable.
  • Rhythm. Calculations should be carried out for several months in order to understand whether the length is always the same. If it is systematic and the deviation does not exceed 1 day, then the indicator can be taken into account. Otherwise (for different sizes: from 25 to 30 days in different months), the cycle is considered irregular and will not help in mathematical calculations.
  • Normal menstrual flow. The number of days, the abundance, structure and nature of the bleeding speaks of the rhythm of the processes. In case of imbalance, changes in the length of menstruation and other failures, it is required to diagnose violations.
  • Information about the state of the level of hormones in different periods. Hormones are responsible for the formation and nucleation of a cell, for its "release" into the reproductive tract, for the normal passage of all stages of pregnancy in general. For each stage, its own hormone is responsible, which must be contained in a certain volume so that everything proceeds without interruption.

Calculation of the day for conception

The easiest and most effective way to calculate the sex of a child is by ovulation and the date of intercourse. It has been confirmed by research by scientists and specialists and has proven its reliability to the greatest extent. Possessing the minimum baggage of knowledge in the field of anatomy and the reproduction process, one can understand how legitimate it is.

Let us recall the basic principles of the fertilization process and the influence of cells on the formation of the sex of the embryo:

  • The female cell has only X chromosomes, which do not determine the sex of the embryo.
  • The sperm of the male, which contain the X chromosome, are responsible for the creation of the female embryo (XX).
  • Sperm type Y, will result in the birth of a son (XY).

It should be understood that the Y-chromosomes are characterized by mobility and the female chromosome will reach the female much faster than the X-cells. If she is ready and at this moment is in the genital tract, then the conception of a boy is inevitable. If the Y-cells have time to die (because they live only a day) until the cell is born, then there will be no one to fertilize it except X. They differ in vitality and are able to live in the genital tract for several days, waiting for the egg.

  • To give birth to a son, it is necessary to carry out a productive act at the time of ovulation, when the cell has already ruptured the follicle and begins to move towards the uterus.
  • For a girl, a more "calculating" tactic is needed. You need to find out your exact moment of "birth" of the cell and 2 days before it to carry out the act. In this case, all Y will die in a day, and only after that the cell will appear. Y has no chance of waiting for her to appear. X, having no nimble competitors, will calmly fertilize the egg.

How to calculate ovulation

To use the method, you must be able to accurately determine your ovulation periods. Mathematical calculations are carried out according to the formula: DC - 14. Where DC is the cycle length. It is very easy to explain the number 14. To do this, you need to understand the process of cell nucleation and the principles of the body. They occur in the following stages:

  • The origin of the follicle in which the cell grows and develops. Each stage has a different duration and it is he who affects the length of the cycle as a whole. May be 11-17 days.
  • The stage of ovulation, when the cell ruptures the bubble and goes into the fallopian tube. Duration 1-3 days, individually, as it depends on the viability of the cell. She normally lives for a day.
  • Recovery phase. In the absence of fertilization, the cell dies. A corpus luteum grows on the ovary, producing a hormone necessary for conception and pregnancy. The ovaries are normalizing and preparing for the new "job" of cell production. All lasts 14 days. In rare cases, 12 days.

It is the knowledge of the same length of the third stage for any organism that makes it possible to identify exactly the moment of ovulation and calculate the sex of the child.

Irregular ovulation

If the rhythm is broken, the mathematical approach will not help a woman. It is better to use tests here. They are able to detect the concentration of the hormone in the urine, which is released at the moment of follicle rupture. Having determined its increased content, the woman has several hours to have intercourse. But in the case of conceiving a daughter, you must first check with tests in order to understand the inherent nature of the change in shade on the strip. In the designated month, already identify the days on the eve of the expected ovulation, comparing with the first samples.

The use of tests that detect the concentration of salts in saliva is more suitable for girls suffering from irregular processes. The device allows you to see a gradual change in the structure of salts and predict the speedy exit of the cell.


You can also use testing to validate your calculations. Another way is to monitor your body. During ovulation, the following changes occur:

  • the chest swells somewhat;
  • cervical mucus appears abundantly, having a viscous structure;
  • there is pain in the side of the ovary.

Online calendars for calculating ovulation and baby gender

If you want to calculate the sex of a child online, so as not to dive into complex calculations, you should understand that they are based on the same formulas. For example, you can check the forecast at this link.

You will need to set your criteria for one of the calculation options:

  • By cycle length: in addition to this parameter, you need to set the date of the last menstruation and the duration of bleeding.
  • By date: enter the days of the last two periods.

In any case, the woman will receive ready-made calendars for several months (specify their number in the settings) with the following marks:

  • Days of menstruation;
  • Days for the act to increase the likelihood of conceiving a girl;
  • Day of cage release;
  • Days favorable for the birth of a son.

This option is also not very suitable for irregular cycles, because it will show a large error. Such a lady is advised to follow the rhythms through the temperature graph. It is necessary to take measurements rectally for several months and mark the indicators on the graph. Before the rupture of the follicle, the temperature drops slightly, then rises again. Such a peak will indicate the onset of an auspicious day. Considering the changes in the curve on the graph, a woman will see the day before or a specific moment of ovulation and will be able to predict the possible outcome of intercourse.


Calculate the sex of the child using tables

While looking for other methods of how to calculate the sex of a child, a table developed by the ancient Chinese or Japanese can suggest a solution. Their reliability is questionable, but many are happy to calculate the options and try to set the optimal months for them.

Chinese table

The Chinese table has been known since ancient times. It is believed that the wives of the emperors used it to plan an heir. It was compiled according to the principle of the lunar calendar, but it was not possible to identify which factors it takes into account and what the forecast depends on.

Using the table is very simple:

  • Find the line corresponding to the girl's age.
  • The vertical columns contain the months. Find the nearest and see the predictions.
  • Schedule acts in the months when the desired result is expected.

In view of the large presence of negative reviews and not trusting such tables to mothers who have already conducted analytics on their children and were unhappy with the answer, information appeared regarding the miscalculation of age. It is believed that the Chinese women call the birthday directly the conception. This means that you often need to look at another line, if you add the moment of being in the womb (9 months) to your age. But there is no confirmation of such information from serious sources.

Japanese table

If the Chinese pregnancy calendar allows you to calculate the sex of the child only by two parameters, then the Japanese one has a more complex structure. Here you need to first compare the months of birth of future parents and find the check digit at the intersection of the graphs. Consider its characteristics already in the second table:

  • Find a column with your criteria.
  • Look at the boy / girl column and select the most probable rows in them (filled cells 5-10).
  • Draw a line to your column and see which month corresponds to a given value.
  • In the absence of an indicator for such parameters in your column, you need to evaluate the most probable: 2-3 cells or more than for the second option.

How the calculation algorithm works in this table is also unclear. But due to some complexity and due to the characteristics of both parents, users trust her more.

Calculate the sex of the unborn child by blood

When undergoing tests at the time of conception planning, spouses are tested and examined. Based on this data, gender can also be predicted.

Blood types

Special tables have been developed to calculate the sex of the child by blood. It is based on the principle of a blood group, which can be predicted in an embryo. The gender is also determined. In particular:

  • The mother has group I. If the father has I or III, there is a high probability of giving birth to a daughter, with II and IV - a son.
  • Mother II. If the future Pope I or III has a son, II and IV are expected to have a daughter.
  • Woman III. In all cases, the birth of a son is more likely. Only with the blood of group I from the dad, it is possible to predict a daughter.
  • Woman IV. In all cases, it is more likely to "get" the girl. But if the father has group I, then a son is practically guaranteed.

In most cases, this prediction coincides with the result obtained, but there are still exceptions. It's no secret that one couple has children of different sexes, but their blood groups have not changed in any way. Therefore, this forecast also has exceptions.

Rh factors

Check in the hospital and the Rh factors of the spouses. If they do not match, sometimes it is not possible to get pregnant for a long time. And some situations are fraught with the development of a baby with abnormalities in the immune system. The situation with a negative rhesus in the mother and positive in the father is especially dangerous if the embryo also receives a positive one.


The forecast for rhesus looks like this:

  • With the same rhesus in parents - the probability of having a daughter;
  • With different - a son.

You can also calculate the sex of the child by blood renewal. This theory is based on the principle that the body undergoes a rejuvenation procedure every few years: 3 - in a woman, 4 - in a man. It is believed whose blood is "younger" will have a greater effect on the sex. The calculation takes place from the year of birth and the cycle of renewal is calculated. It is determined which of the spouses was the last to experience rejuvenation. If a person had a serious injury that caused a lot of blood loss, then this year the update took place unscheduled and the countdown should be taken from him. For women giving birth - from the date of birth.

As far as this theory is correct, the opinions of specialists also differ. If you want to use it, you should also enlist more reliable calculations regarding ovulation and the viability of each type of sperm (scientific method). So, by combining several methods, it is easier to achieve the desired effect.

Pregnancy Calendar

Already at the planning stage, it is possible to identify pregnancy by week, calculate the gender of the child and set an approximate date of birth. It is clear that this is rather arbitrary and changes may occur in the body that lead to earlier childbirth, but it will not be superfluous to understand the dates and prepare for them.

Today there are special services that can calculate all these parameters, for which you only need to enter the length of the cycle and the last date of menstruation. The calculator will calculate and give a complete picture of the expected pregnancy.

The advantage of our calculator is the explanations for each week regarding the development of the fetus, so that the woman understands what state the embryo is in now and when to expect "shocks", etc. In addition, we have medical indications and advice for every week. For example, if in the first week you need to avoid bad habits and not take medications without the approval of a doctor, then in the second week it is already possible to take folic acid, which prevents the development of neural tube defects.


At the 14th week, the first ultrasound is likely to be performed, which is necessary to assess the level of development. The unpleasant symptoms of the first quarter are already fading away and are not a problem. During this period, it is better to consume more liquid, as constipation often occurs due to the slow "evacuation" of food. And already at the 16th week, you can identify on an ultrasound scan what gender the baby is. From the 18th week, he begins to distinguish the mother's voice and respond to it. It is believed that talking with him, reading books, listening to music at this stage have a beneficial effect on development.


At the 28th week, the baby's active kicks begin. At this time, heartburn no longer suffers, but back pain and fatigue appear. From this period, it is better to start attending courses designed to prepare future women in labor for this procedure, if this has not been done before, to learn proper breathing, and to do special exercises.

At 36 weeks, the doctor begins to check the cervix for softness and openness. If the baby appears at the 37th week, this is usually not fraught with problems, since he is almost ready for an independent life. In particular, the lungs are almost ready to function outside the womb. At 38 weeks, the baby turns his head down, and his body is covered with original lubricant, which is conducive to a normal birth.

You can view a more detailed pregnancy calendar by week and calculate the sex of the baby on our website by following this link.


After studying the listed recommendations, you can plan your pregnancy, calculate the best days for conception, calculate the sex of the child. Using online calculators will allow you to confirm the results and get a ready-made "cheat sheet" for the appointment of acts. Using the pregnancy calendar, you will be able to receive recommendations and advice from doctors, necessary for a given time, every 7 days. Of course, you need to promptly give up harmful addictions, take care of your health, track the regularity of your cycles and be examined by a gynecologist. Further pregnancy should also be monitored by a doctor.

Pregnancy, especially the long-awaited one, is a bright event in every family. And already, only after seeing 2 strips on the test, the couple becomes curious who they will have - a boy or a girl. Most of all, this issue is worried about 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 is not easy to wait so long. Here methods come to the rescue (the ancient Chinese table; renewal of the parents' blood; 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, not a single physician considers these methods to be reliable. From the point of view of medicine, this is comparable to fortune telling on coffee grounds. Only medical methods (genetic research, ultrasound) make it possible to most accurately calculate who the couple is waiting for - 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 biopsy. They are prescribed solely for medical reasons to detect genetic diseases or fetal malformations. They allow you to determine the sex of the child with 99% probability. Such an intervention can cause a miscarriage or premature birth, because the material (amniotic fluid, chorionic villi, umbilical cord blood) is taken from the uterine cavity for examination

Determine the sex of the fetus by ultrasound

It is possible to determine the sex using ultrasound as early as 16 weeks. But more reliable information can be obtained only at 20-25 weeks of pregnancy. In some cases, the specialist cannot see the gender on an ultrasound scan, for example, the fetus is in an uncomfortable perspective or the umbilical cord closes its genitals.

Ultrasound is considered the most effective and safest way to find out the sex of the unborn child. The reliability 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 with the sperm). The gender of the baby is determined at the time of conception. If sexual intercourse took place on the day of ovulation, then sperm carrying male chromosomes will reach the egg faster, which means there will be a boy. If intercourse occurred a few days before ovulation, then the fertilization of the egg will occur with the most hardy 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 determining the sex of the child by renewing the parents' blood. The reliability of the method is 50% - he either guesses the gender or not. Therefore, the method is more suitable for entertainment.

Blood renewal theory

There is an assumption that the blood of the parents influences the sex of the child. Every person has a renewal of blood in the body throughout his life. In women, the blood is renewed once every three years, in men - once every four years. And which of the parents at the time of conception has more "fresh" blood, the same sex will have a baby. However, early blood renewal is also possible with blood loss of more than 1000 ml, for example, during a surgical operation, 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. Suppose the future dad is 29 years old, and the mother is 23. Further, simple arithmetic operations are carried out: the age of the woman is divided by 3, and the age of the man by 4 (23: 3 = 7.7; 29: 4 = 7.3). As you can see from the example, the father's remainder is 0.3, and the mother's is 0.7, and since it is 3.7, the couple is likely to have a boy.

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

We offer to determine the gender of the baby by updating the blood on 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 donated blood, surgery, childbirth, then instead of the date of birth, the date of the last blood loss is indicated.

(calculation will take a few seconds)

Determine gender by fetal heart rate

This technique is based on the statement that the number of heartbeats in boys and girls is different. Before ultrasound machines, many gynecologists could use a stethoscope to find out gender by heartbeat. Gynecologists noticed that girls 'hearts beat more often - 150 and more beats per minute, and boys' hearts - within 120-140. However, this technique has not been proven, because many factors can affect the heartbeat, for example, excessive fetal activity, possible hypoxia, uterine tone, gestational age, time of day, increased blood pressure at the mother.

According to the Chinese calendar

It is possible to find out the sex of the child according to the ancient Chinese calendar, which is more than 700 years old. The Chinese believe that its accuracy is very high. It was on him that in ancient times they determined who would be born to a couple. The method is based on the relationship between the 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 9 months old (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 its age, in addition to 9 months. The fact is that during this period, the Chinese begin New Year.

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

To determine the sex of the unborn child according to the ancient Chinese table, use the online calculator, where you must indicate the month of conception and the lunar age of the woman.

Determining the sex of the unborn child

The method of "blood renewal" is based on the fact that the blood of men is renewed every 4 years, and for women - every 3 years. If dad's blood is "newer" - a boy will be born, if mom's - a girl. It is necessary to take into account all the large blood loss, after which the blood was renewed - operations, childbirth, miscarriages, abortions, blood transfusions, donation of blood.

Ancient Chinese table for determining the sex of a child by the time of conception

Want to test yourself? First find the age of the mother, then correlate it with the month in which the child was conceived. You will get a plus or minus, representing a boy or a girl, respectively. So you can check the birth of your own or relatives.

Given the age of the intended mother, which is indicated in the table from 18 to 35 years old, 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!

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

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 9 months old (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 its age, in addition to 9 months. The fact is that during this period the Chinese have a New Year.

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

To determine the sex of the unborn child according to the ancient Chinese table, use the online calculator, where you must indicate the month of conception and the lunar age of the woman.
