In any society, family planning is considered one of the main and vital aspects. And at this stage, all parents think about the field of their future baby. Who it will be: a boy or a girl is the first question that worries future mom and dad for nine months. The sex of the child can be determined by updating the blood, based on the fact that at certain times in her life she “becomes younger” or “grows old”.
Female blood is renewed every 3 years; in men, blood is renewed every 4 years. If you start the calculation from the age of 12 years, then the woman’s blood will be updated at 15, 18, 21, 24 years and so on. Male blood freshens at 16, 20, 24 and the like. The sex of the child can be determined by updating the blood, based on this technique. Who has blood younger in the process of conception, the same sex will be in the child. For example, if a man is 31 years old and a woman is 25, a girl will most likely be born, since the blood of the future mother has only been updated, and this has not happened to the future father.
Blood renewal process
To determine the gender of the child, blood renewal can be calculated taking into account three- or four-year cycles. But it should be noted that this process is natural, and it cannot occur under the influence of external factors. Suppose a person constantly donates blood as a donor or he needs an urgent blood transfusion - this technique does not apply to him anymore. Specialists even doubt that it is possible to determine the sex of the child by updating the blood. They consider this term and this technique far from science. In addition, what if the parents were born on the same day and one year?
How to find out the gender of the child, given the cycles of blood renewal
You can determine the sex of the child by updating the blood, if you establish how many times it has changed for each of the parents. That is, it is enough to know the age of future dad and mom. The age of a man is divided into four, and the female age is divided into three. Whose coefficient will be lower, the same will be the baby.
But at the same time, some subtleties must be taken into account. Firstly, the age of the parents must be taken at the time of conception. Secondly, in women with a negative Rh factor, the blood is not renewed every 3 years, but every 4 years, as in men.
Blood Update Table
The sex of the child, of course, can be found using the parental blood renewal table, but this technique is not the most reliable. Parents can also find out what gender a child will be born based on their blood type. True, the probability of this method is more like guessing, but these methods are not complicated and, in principle, can be checked.
Determining the sex of the unborn baby using a blood test
The most reliable way to determine the sex of the child is to donate blood from a vein for analysis. Mom can get this examination already at the seventh week of pregnancy. What is its essence? As you know, in the circulatory system of the expectant mother contains a small amount of fetal DNA. In human cells there are X- and Y-chromosomes, while the latter are inherent only to men. That is, if at least one Y-chromosome is present in the mother’s blood, then for sure she will have a male child. This method is considered 99% reliable.
Believe or not believe the above methods - your business. Yes, in principle, for most parents it does not matter who is born. The main thing is that the baby is healthy.
