The most an important event in the life of any family is the birth of a child. And if the gender of the first-born, as a rule, does not particularly concern parents, then the gender of the second baby would like to be known in advance.
Advanced modern moms explore everything possible methods to determine the sex of the child and compare the results in search of the truth. Let's look at how to find out the sex of a child by blood renewal and whether this method gives a 100% guarantee.
Description of the method
The method of determining the sex of a child by blood renewal at first glance seems quite interesting and reasonable. Some researchers have concluded that human blood is renewed every few years. To find out the sex of the unborn child, it is necessary to determine which parent’s blood changed later. If mom's blood is younger than dad's, then a girl will be born. If the parent’s blood was renewed later, then a boy will be born.
Some features of blood renewal
In women, the process of blood renewal occurs once every three years. In men, less often - once every four years. However, blood renewal can occur under other circumstances. For example:
- during blood transfusion;
- when donating blood for donor purposes;
- in case of large blood loss due to: operations, childbirth, abortions, miscarriages, injuries, etc.)
These facts must be taken into account when calculating so that the result of determining the sex of the child by blood renewal is as reliable as possible. This means that the calculation must be carried out from the day when an event occurred that affected the period of blood renewal.
The mother's Rh factor also affects the results of determining the sex of the child. If the expectant mother has a negative Rh factor, then the sex of the child is determined by whose blood changed first.
Formula for determining the sex of a child by blood renewal
To determine the sex of a child, data is used based on the cyclical renewal of the blood of a woman and a man depending on the date of their birth. To make the calculation, you need to know the exact age of the parents at the time of conception of their child. The age of the mother will be divided into “3”, and the age of the father – into “4”, where “3” and “4” are the periods of blood renewal of a woman and a man, respectively.
Let's determine the sex of the unborn child for a 28-year-old woman and a 30-year-old man.
- mom 28:3=9.3
- dad 30:4=7.5
We compare only the remainder of the resulting numbers: 3 is less than 5. A woman has younger blood. This means a girl must be born.
An easier way
So, women's blood changes at 15, 18, 21, 24, 27 years old, etc. Men's blood renewal occurs at 16,20,24,28,32,36 years, etc. For convenience, we counted with adolescence. Let's determine the gender of the child of the same fictitious parents: mom - 28 years old and dad - 30 years old. Mom’s blood changed one year ago, and dad’s – two. A girl must be born.
What is the probability of a successful prediction?
No one can 100% confirm the reliability of the method of determining the sex of a child by updating the blood. The reality of such a forecast is 68-88%. And some sources indicate 50% of the veracity of this method. In addition, the smaller the difference in the calculations, the lower the accuracy of determining the sex of the child.
After analyzing a lot of information and being completely confused, I decided to omit the statistics and conduct an experiment. Taking into account all the above recommendations, I calculated who should have been born to me 14 years ago.
All calculations showed that there should be a girl sitting in the next room. But there, actively pressing the laptop buttons, his beloved son is storming the Internet. And believe me, not once in my life have I thought about why this is not my daughter. After all, we love our children not because of their gender, but because they exist.
Many people in modern world We are used to planning our future. The birth of a baby is no exception. Increasingly, future parents want to know in advance who will be born to them. One of the popular research methods is calculating the sex of the child using How much can you trust this method? This is exactly what this article will tell you about. You will learn how to calculate the sex of a child using blood renewal. You can also find out the features of this process.
Blood renewal
Normally, this process occurs in every person. In addition to blood, the mucous membranes and skin are also renewed. does not require outside intervention. It happens on its own.
The timing of the described process is set individually for men and women. For example, males undergo this procedure once every four years. Among girls and women, renewal occurs more often. Their blood is purified every three years.
Calculation of the sex of the child by blood renewal
The calculation can be done using two methods. The first involves dividing the age a person was at the time of conception by the required number. The second begins counting directly from the date of birth. However, it is less convenient. This is due to the fact that many phenomena can occur during life that affect the period of blood renewal.
How to calculate the sex of a child based on blood renewal? When using the first method, you need to find out the full number of years of the mother and divide the resulting number by three. Over the years, fathers do the same. However, the divisor in this case is four. The results obtained are compared. Whose blood turns out to be younger, a child of that gender will be born to that couple.
How to calculate the gender of a child using blood renewal using another method? In this case, you take the woman’s year of birth and add 3 to it, then another 3, and so on until the moment of conception. You do the same with your father’s age. Only in this case you need to add 4.
Calculation example
- Option one. The mother is, for example, 26 years old at the time of conception. This number must be divided by 3. The result will be 8.7. The father's age at this moment is 27 years. Divide these years by 4 and get 6.8. Let's compare the balances. The mother's blood is younger. Therefore, it will be a girl.
- Second way. The woman was born in 1989. Her blood will be renewed in next periods: 1992, 1995, 1998, 2001, 2004, 2007, 2010, 2013, 2016. The man was born in 1986. His blood will undergo renewal in 1990, 1994, 1998, 2002, 2006, 2010 and 2014. If the child is conceived in 201 4 years old , then the couple will have a boy.
Special cases
How to find out the sex of a child by updating the blood of the parents if they were born on the same day? Experts still cannot find the answer to this question. Some scientists say that in such a situation there is a big difference. Other scientists say that two babies are born at the same time when the remainders are equal.
In any case, in this situation, as in other cases, it is necessary to take into account external factors that may affect blood renewal before calculating the sex of the child based on the blood renewal of the parents.
The popularity of the described method and its reliability
Researchers say that currently there are a lot of different ways to determine the gender of a planned baby. These include all kinds of tables and pentagrams, online applications and calculations. The most popular among them is the ancient Chinese table and method of blood renewal.
Despite the popularity it has gained, experts say that the effectiveness of this method is quite low. So, some scientists call the probability of an accurate hit 2%. Others are talking about 50%. How is it really going?
Can the method described above be trusted?
Determining the sex of a child by the renewal of the parents' blood is quite simple. However, this does not guarantee that you will receive accurate data. In most cases, a successful coincidence is just an accident. This fact is explained as follows.
During fertilization, two cells fuse: male and female gametes. The egg contains only sperm, but its structure is more interesting. It may contain a set consisting of X chromosomes. In this case, the couple will have a girl. When a male cell contains one child chromosome, a boy is born in the near future. Based on these data, we can conclude that human blood has absolutely no effect on gender future baby. All methods of this are recognized as mere entertainment rather than true information.
Opinion of married couples
Many families who were told how to calculate the sex of a child using blood changes were able to plan in advance for the birth of a boy or girl. They simply made a calculation and found out in what years and months they would have a baby of one sex or another. These couples respond extremely positively to the described method.
The majority of tested individuals refuted the above theory. Simple calculations did not confirm the birth of a child of a certain gender. Exactly on this information scientists rely on, citing the percentage of positive outcomes of the calculation.
Necessary information
Before you try to renew your blood, you need to take into account all the data. Thus, a change in the bloodstream can occur not only at the above intervals. This process is also sometimes influenced by external factors.
Premature renewal of the bed occurs during childbirth, operations, severe blood loss, various injuries, treatment, blood and plasma transfusions, as well as among donors. It is from this moment that a new countdown begins. Many couples do not take this information into account. That is why their data and the actual outcome of events do not agree.
A short summary of the article or conclusion
Now you probably know by updating the blood of his parents correctly. Choosing this method calculation, always take into account full information about both partners. Otherwise, the data may be incorrect.
It is possible to know absolutely accurately the sex of the unborn baby only during ultrasound examination carried out at 20 weeks of pregnancy or later. However, even in this case the assumption may be wrong. You should not put much faith in the described calculation method. Good luck to you and may your wishes come true!
Pregnancy, especially a long-awaited one, is a bright event in the life of 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 examination. 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 gender 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. coffee grounds. Only medical methods (genetic research, ultrasound) allow you to most accurately calculate 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. These studies are prescribed exclusively for medical indications 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, 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 of the fetus on an ultrasound, for example, it is in an awkward angle or its genitals are covered by the umbilical cord.
Ultrasound is considered the most effective and in a safe way find out the sex of the fetus. 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 in 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 a 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 among expectant parents is to determine the sex of the child by renewing the blood of the parents. The reliability of the method is 50% - it either guesses the sex of the fetus 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 blood renewal 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. All you need to do is enter your parents’ date of birth and know exact time 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 find out the sex of the fetus by its 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 many factors can influence the heartbeat, for example, excessive activity fetus, possible hypoxia, uterine tone, gestational age, time of day, increased blood pressure at the mother's.
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 life 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 are experiencing 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.
Of course, it is important for every parent that their child is born healthy and strong. However, for many no less important issue is half a baby. Some people dream of a boy, while others, on the contrary, want to have only a girl. There are many methods for calculating when exactly you need to conceive in order for a child of a particular gender to appear in the family. Do they give everything exact result, the issue is controversial. There is a method based on renewing the blood of the parents.
What is the theory of blood renewal?
The method of predicting the sex of a child by renewing the blood of the parents has its roots in ancient times (see also:). Even then people knew that human body Almost everything changes periodically - from blood and tissues to mucous membranes and cells. This knowledge has reached the modern world.
Such physical changes continue throughout life. However, in women and men, similar changes occur through different period time. The fair sex renews itself every three years, but the stronger sex renews its internal reserves less often - once every four years. It is these temporary differences that give rise to attempts to determine the sex of a child by the blood of the mother and father.
Let us dwell in more detail on the renewal of blood based on modern research, and not old beliefs. Blood consists of a large number of different elements and blood bodies. Red blood cells rightfully bear the title of the longest living. The number of these blood cells in an adult reaches 25 trillion. The process of updating them takes on average about 120 days, that is, they are updated in 4 months. As for platelets and leukocytes, they life cycle is only a few days.
Drawing conclusions from this, we can say that the theory about blood renewal every 3 and 4 years is wrong. Despite this, many mothers continue to calculate the sex of the child before conception. In a similar way, and often they manage to correctly determine the gender of the baby. According to statistics, the chance of correctly finding out the gender of the unborn baby is 68–88%, and these are impressive numbers, especially for an erroneous approach. For this reason, the technique still remains popular among expectant mothers and fathers.
How can you plan the sex of your child using the blood renewal method?
Dear reader!
This article talks about typical ways to solve your issues, but each case is unique! If you want to know how to solve your particular problem, ask your question. It's fast and free!
It’s clear what the method is based on, but how can such a theory be applied to determine sex before conception? The main idea is that the baby will “choose” the gender of the parent whose blood is younger. If the mother has recently renewed her blood, then the family will have a daughter, if the father has a son.
The main task is to determine who has younger blood at the time of pregnancy planning - a man or a woman. There are two ways to calculate who will be born after childbirth, a boy or a girl:
- Using special tables based on the age update calendar. They have come to us from very ancient times. Horizontally in the table the full age of the future father is indicated, and vertically the full age of the mother. The intersection of these lines will answer the question of interest. For example, if at the time of planning a child the mother was 32 and the father was 36, then after the birth a boy will appear. This is a simple method, but whether such a test should be trusted is up to parents to decide.
- Calculation. Without using a table, you can calculate the sex of the child yourself. Counting will also not take much time and effort. To determine the gender, you need to divide the number of full years of the mother by 3, and the number of the father by 4, and then simply compare the quotient of the division. Whichever parent has the lower result will pass on their gender to the baby. For example, mom is 22 and dad is 27. We divide 22 by three and get 7.3, and divide 27 by 4 and get 6.75. Dad's value is less than mother's, which means there is a high probability of having a boy. If the values are equal, then there is a chance of becoming parents of twins. This is possible if the blood of both parents was renewed in the same year.
There is a third option for calculating who will be born, a boy or a girl. To calculate this, you need to know the year of birth of each parent and the year in which the family wants to plan the conception. For example, my mother was born in 1994, which means that her blood was renewed in 2015, her father was born in 1998, and his blood was changed in 2016. If you conceive in 2016, a son will be born, since the father’s blood is younger.
What do scientists think about calculating the sex of an unborn child based on the renewal of the parents' blood?
Although many parents manage to calculate the gender of the child, and spreadsheet tests also give a high percentage of matches, scientists do not take this method seriously. Doctors consider the idea that it is realistic to calculate the sex of a child by changes in the blood to be superstition.
The method based on blood renewal, as well as tables and calculations in accordance with it, are not able to take into account even all the nuances concerning this valuable biological fluid. If you rely solely on such a test before conception, then it would be useful to take into account the factors of blood loss that affect the process of blood change, leading to its earlier passage.
The process of blood renewal is influenced by:
- transfusion and donation of donor blood;
- surgical intervention;
- injuries;
- childbirth;
- spontaneous and induced abortion.
Doctors believe that even minor injuries or cuts can trigger blood renewal. Without carrying out laboratory research It is impossible to say exactly when the blood was renewed, which means the result of the calculations is also controversial.
This opinion of experts does not interfere ordinary people consider the methodology reliable, trust it and carry out calculations. Women all over the world often resort to a blood renewal test to calculate the sex of their unborn baby in a few minutes.
What actually determines the sex of the baby and is it possible to “order” it?
In accordance with the research of biologists, which has a scientific basis and has received worldwide recognition, if the sperm that fertilized the eggs was a carrier of the X chromosome, then the baby will be female; if the sperm has a Y chromosome, then a boy will be born. The blood or age of mom and dad have no effect on this process.
Those wishing to give birth to a child of a certain gender “by order” should take into account that sperm carrying the Y chromosome are more mobile, but less tenacious, and their counterparts carrying the X chromosome move more slowly but live longer. Therefore, in order to conceive a boy, a man and a woman need to have sexual intercourse on the day of ovulation, and for the birth of a girl, 3-4 days before it.
However, this method can also misfire. It is absolutely possible to “order” a son or daughter only in the case of in vitro fertilization and subsequent transfer of embryos of the desired sex.
Numerous clinical researches showed that in the human body, used cells are replaced with new ones with a certain periodicity. The process of blood renewal is of utmost importance, during which the body is cleansed of old cells and toxins, and new ones receive the necessary amount of nutrients and oxygen.
Most doctors believe that this process takes its own time for each person, depending on the individual characteristics of the body and age. But it has been proven that the fair sex undergoes renewal a little faster than men.
Many people ask why the body renews blood and what factors influence the rate of hematopoiesis. This will be discussed further below.
Process characteristics
In international medicine, blood renewal is called “hematopoiesis.” Its progress is 80% dependent on correct functioning bone marrow.
The process of biomaterial renewal has not yet been fully studied, world scientists They are trying to study its features, so a reliable and correct table of hematopoiesis has not yet been compiled.
The biomaterial consists of several types of cells that perform various functions. Basically the following are subject to replacement:
.jpg)
- Red blood cells. The most common type of cells, they contain hemoglobin and iron. Red blood cells enter the blood from the bone marrow and are responsible for the supply and saturation of oxygen to other tissues. Doctors have found that the lifespan of red blood cells is 4 months; after this time, the cells begin to die in the liver and spleen.
- Leukocytes. The main task of these bodies is to protect the body from various viruses and pathogenic microorganisms. They prevent infection, and if malicious compounds penetrate, they detect and destroy them. There are several types of leukocytes in human blood: eosinophils (protect intestinal tract And respiratory system), neutrophils (the functioning of immune system), monocytes (fight inflammatory process), basophils (prevent the development of the allergic process).
- Platelets. They are responsible for restoring and strengthening the walls of blood vessels, activating the coagulation process when receiving cuts and injuries, and preventing blood loss. Unlike other elements, platelets live from 8 to 12 days, after which they die. In their place, new ones are formed.

What determines the update speed?
Blood renewal - difficult process, depending on various factors. Today, the theory of hematopoiesis is gaining great popularity, especially among young couples planning to conceive a child.
Numerous studies have confirmed that if a child is conceived when the biomaterial of both parents is completely renewed, the likelihood that he will be born healthy, without various pathologies, increases to 98%.
Blood in the body changes in any case, but the rate and number of cells replaced depend on the physiological state of the person and the exposure external factors.
Main reasons influencing the process:
- gender identity;
- Availability chronic diseases;
- nutritional features;
- taking medications of certain pharmaceutical groups;
- Availability bad habits;
- receiving serious injuries accompanied by heavy blood loss;
- donation;
- Lifestyle.
It is impossible to say exactly how many years or months the update lasts, since it depends on the characteristics of a particular person.
In men
.jpg)
Recent studies have confirmed that in men this biomaterial is completely renewed every 4 years. During this period, a person becomes as strong and healthy as possible.
If a married couple is planning to conceive a baby, experts recommend waiting for this moment, as the baby will be strong, resilient and strong.
The optimal age for a man to conceive a child: 24, 28, 32 years. But it is important to remember that replacement can occur at other times. This happens if a person received serious injuries or by donation.
Among women
Unlike representatives of the stronger sex, in women renewal occurs a little more often - once every 3 years. This is largely due to the fact that during menstruation a small amount of biomaterial is lost, as a result of which recovery is faster.
Failure of the full update cycle can occur due to termination of pregnancy (both medical and surgical), donation, or recent operations.
All these processes will affect your health and condition, so blood renewal may happen earlier. It is impossible to answer how many years later the process of hematopoiesis will begin.
Update during the menstrual cycle
During menstruation, women on average lose about 150 ml. By medical standards, this volume is quite insignificant (during a donation, a person gives about 450 ml of blood).
Doctors claim that during this natural process the blood is also renewed, but in too small quantities. However, this affects the overall renewal cycle, and in women it happens a little faster.
During pregnancy and childbirth
.jpg)
During pregnancy, the blood is practically not renewed, the process slows down.
This feature is due to the fact that the body devotes energy to the life support of the baby, and other processes are “frozen”.
The situation is completely different after the baby is born. During childbirth, women lose a large number of blood, also profuse bleeding observed during the following days after birth.
The body begins to quickly and intensively cleanse itself of the baby’s waste products, and the process of hematopoiesis is activated.
Update calculation
Many health-conscious people ask their therapists whether it is possible to calculate when blood fluid renewal will begin.
It must be taken into account that each person's renewal cycle is slightly different. Also, the period of hematopoiesis largely depends on anatomical features and the impact of external factors. If a person is a donor, his renewal will occur more often and faster, this will become an individual feature.
International medicine is of the opinion that in men and women the biomaterial is renewed in the following way:
Age dependent
The number of years lived has virtually no effect on the rate of blood replacement. But human health directly depends on age. The more significant the latter, the more stress, infections and nervous experiences a person has encountered. This directly affects your overall health.
Planning a pregnancy
IN Lately future parents began to pay great attention to the quality and age of blood. Many experts claim that the health and gender of the baby depend on the characteristics of the biomaterial.
- The father's age must be divided by 4.
- Mother's age is 3.
- Then you need to compare the remainder of the numbers.
Whose remainder is smaller, the parent determines the future gender. If the father has less balance, a boy will be born. If the mother has a girl. When the remainders are the same, the probabilities of having a son or daughter are equal.
How to speed up the update
If necessary, the process can be accelerated artificially. Most easy way To do this, sign up as a donor. If a person donates blood once a month, the formation of new cells in him accelerates several times.
If we talk about the blood transfusion procedure, it is ineffective and will not help improve the health of the body. This technique also increases the risk of side effects..
Foods that are good for your blood
Improve blood quality and saturate it useful microelements you can if you stick to it proper diet. Research has confirmed that the foods that are most beneficial for your blood are:
- Carrots, beets. They are recommended to be consumed fresh, and juices can also be made from them.
- Garlic. If you swallow a clove of garlic before going to bed, hematopoiesis will accelerate.
- Sea fish. Almost all varieties contain a large amount of omega-3 acids, which helps remove cholesterol and cleanse the blood.
- White cabbage. It is recommended to make salads based on it. Vegetable subjected heat treatment, loses its properties.
- Apples.
- Pomegranate.
- Nuts. They contain a lot of iron, magnesium, potassium and various vitamins.
Some scientists are still skeptical about the theory of blood renewal and consider it false, especially when it comes to planning a child. Nevertheless, many women who calculate the gender of the child using this theory note that the results coincide with the calculations.
It is necessary to understand that this biomaterial in the body, like all other cells, is renewed in any case, but it is almost impossible to calculate the frequency of the process, since it is very complex and depends on individual characteristics.
