The most important and long-awaited event in lifeevery woman - the birth of a baby. And if the sex of the first child does not worry you at all, then the answer to the question of what gender will be the second one wants to know much in advance. And in some cases, and predict. Plus in families where there is already one boy, my mother wants to give birth to a baby daughter. And vice versa. Now we know a lot of ways to determine the sex of the baby. There are scientific methods, people's signs, and beliefs. In this regard, a large number of modern mothers study various literature, passes tests, compares the results in search of truth. So let's consider how you can find out who will be born - a boy or a girl - using the method of blood rejuvenation. Some moms say that it really gives almost 100% result. But is it really so? 
Determination of sex by blood: truth or fiction
What is the theory of determining the sex of the baby,based on blood rejuvenation? As experts say, every person after a certain time there is a process of updating the mucous tissues and the blood itself. At the same time for each sex these gaps are different. So, for example, a woman rejuvenates blood once in three years, but for men only once in 4 years. For the sake of justice it is worth noting that this method does not apply to scientific methods, therefore, the accuracy of the result can not be guaranteed. Its effectiveness, according to scientists, is only about 2%. 
The main essence of this method
Method for determining the sex of the baby by updatingblood may first seem completely justified and quite interesting. A large number of researchers concluded that once in a few years the human blood is completely renewed. So, in order to find out who will be born at mom's - a girl or a boy - it is necessary to find out what the test says, who of the parents had the blood changed later. In the event that the mother's blood is much younger than my father's, the girl, most likely, will be born. And vice versa, if the parent's blood has been renewed later, then there will be a boy.
Features of blood renewal
As it was said earlier, blood rejuvenationa woman passes only once every three years, a man - once every four years. But despite this, the blood can be renewed and completely under other circumstances. Therefore, if you decide to find out the sex of the future baby, be sure to write on the leaflet whether it was with you or your husband that it could contribute to the renewal. For example, this happens:
- during blood transfusion;
- during the delivery of blood at transfusion stations;
- in the case of large blood loss during childbirth, surgery, abortion, injuries, miscarriages and so on.
Do not forget that all these factors are necessarycertainly taking into consideration when counting. This is necessary to ensure that the result of determining the sex of the future of a tiny creature with the help of the method of blood rejuvenation was more reliable. That is why the calculation must be made from the very day when the event occurred that led to the renewal. In addition, the sex and blood group are calculated. The Rh factor of the expectant mother is also of great importance in determining the sex of your unborn child. If the mother is Rh negative, then the sex of the crumbs will depend on the one whose blood has changed before.
How to calculate the sex of a child correctly
In order to find out who will be born to you -the future boy or girl -, it is necessary to use all the data that are based on the cyclic rejuvenation of the blood of a man and a woman (depending on the exact date of their birth). The calculation is made on the basis of the exact age of future parents at the time of conception. In this case, the age of the father should be divided by 4, and the age of the mother - by 3, where 4 and 3 - the periods of blood renewal in men and women. Let's consider in more detail how it is possible to determine the sex of a future child, naturally, using the method of blood renewal. So, who will be born to a man at the age of 30 and women 28 years old? Mother's age is divided into three. As a result, we get 9.3. Dad's age is divided into four, resulting in 7.5. In this case, we take into account the remainder of the figures: the age of the father is 5, which is much more than the age of the mother - 3. Therefore, the woman's blood is much younger, which may indicate that a girl is likely to emerge. But to accurately predict the sex of the child is unlikely to work. Another more complex and interesting example. In the event that the remains are equal to zero, then twins or twins may be born. Mothers are 24 years old. My father is 28 years old. 24/3 is equal to 8, 28/4 is equal to 7. Serious to take this should be if the genus already had such cases. 
How do I plan the birth of a boy or girl?
Date of birth of the father - 1983, and mother -1987. Then take the average age in which some of the fair sex are planning to give birth to a child - 20 years. Consequently, the man's blood will be rejuvenated in 2003, then in 2007. In the case of conception in the period from 2003 to 2007, a boy will most likely appear in the world. In the period of 2008-2011 a girl will be born. In 2011, the blood of the mother and father was renewed, so that this year twins may appear in the world. It is impossible to guess the sex of twins by this method. Of course, the definition of the sex of the child (using the method of blood renewal) is subject to great criticism and discussion. After all, if the rejuvenation of the blood really happened because of its transfusion, then what then? And if the spouses were born in the same year? Then how to make all calculations in order to get an accurate result? The question arises: is there really a probability of a successful prognosis with the help of the method of blood rejuvenation? As mentioned earlier, no one can guarantee the accuracy and accuracy of the method to 100%. Thus, the realism of this forecast ranges from 68 to 88 percent. However, some sources fully assure that this method is true by 50 percent. In addition, the lower the difference in calculations, the lower the accuracy of the result. Therefore, if you want to know the gender of the unborn child, you need to try more serious options. For example, ultrasound.
Learn the sex of the child by blood type
It is believed that the blood group can be determinedsex future child. To this test also should not be taken too seriously, as it gives only fifty percent result. After all, it has not been scientifically proven yet how this can influence the fact that, for example, a boy was born. So, if the mother and father have blood in the first group, the chance that the parents will have a girl is high. The same goes for the second group. Representatives of the fair sex for some reason they love. But the boy will be born, if the partners are 3rd or 4th. There will be a daughter if the pope's blood is related to the 2nd group, and the mother's blood is to the 4th group. If the pope in this case will be 1st or 3rd, wait for the daughter. But before you start counting, think about why it is so important for you to know the sex of the unborn child. If you have a boy, will you love him less? Or do you really need an heir, and your daughter will become a burden? Nowadays, gender identity is not so important. The girl is mother's joy, assistant and closest person. The boy will become a defender, an earner. By the way, that's why in the eastern countries it is forbidden to go on ultrasound in order to know the sex of the future child. After all, the boy for them is the best thing that can happen. And from the fairer sex ladies are trying to get rid of. But, as specialists predict, the situation will soon change when women are catastrophically short. And then the sex of the child will not be so important.
