All couples who are expecting a baby naturally want to find out as soon as possible who they will be born to - a daughter or a son. And some people even initially try to adhere to certain tips in order to contribute to the appearance of a baby of a certain gender. A rather interesting theory, which has gained popularity in recent years, allows you to find out the gender of a child by updating the blood .
Various studies have shown that at certain intervals, blood in both the female and male body is renewed. And the sex of the baby itself, which should be born to a couple, will depend on the blood of which of the spouses was "younger" at the time of conception.
In order to know the sex of the child by updating the blood, you should know that in women blood cells are updated every three years, and in men this time is slightly longer - once every four years. That is, in women, renewal occurs at the age of 15, 18, 21, 24, 27 and so on, and for the stronger sex, respectively, at 16, 20, 24, 28.
Let's look at some practical examples. If the mother at the moment, for example, is 20 years old, and the father is 25, then her blood was last updated two years ago, and there is only one. That is, from the point of view of the theory under consideration, the probability of having a boy is higher.
Let's try to find out the sex of the child by updating the blood, if the woman is twenty-two years old, and the future daddy is twenty-seven. Here, on the contrary, there is a greater chance of the birth of a girl.
If you want to know the sex of the child by updating the blood, you should consider some of the nuances characteristic of this method. Using it, it is very important to consider whether there have been blood loss, surgery, childbirth, abortion, transfusion, etc. If yes, then the count should be carried out, starting not from age, but just from the time of the last blood loss.
The described theory has its supporters and those who are of the opinion that no calculations and no mathematics will help to “plan” a child of a certain gender. And the only way to find out the sex of the baby, in their opinion, is a traditional ultrasound.
However, it was knowledge of the characteristics of the human body that enabled the scientists of Ancient China to compile their own table, in which you can also find out the sex of the child by the mother’s blood, or rather, by her “age”. This takes into account not only the number of full years, but also the number of months. It is believed that in different months (from 1 to 12), the likelihood of having children of different sexes increases.
However, all of the above methods will not allow you to get a reliable result. But already from the 7th week of pregnancy, you can take a blood test from a vein and get an exact answer. As you know, the baby’s DNA is present in small quantities in the blood of a future mother. It is known that two types of chromosomes are present in humans - X and Y, and the Y chromosomes are characteristic only for men. If at least one of these is found in the mother’s blood, a boy will be born with a 99% probability.
Now you know how to find out the sex of the unborn baby by the blood of the parents, and you can plan the pregnancy so that a son or daughter is born, depending on your desire.
