It's no secret that nowadays couples are more consciously approaching the sex of the future baby. To date, there are many ways to plan the sex of the unborn child. These methods are becoming more progressive. Most of these methods are invented by women themselves.
Today, the methods used by our ancestors seem ridiculous and ridiculous to us. For example, several centuries ago people believed that if, during the performance of marital duties, put an ax under the pillow, a boy would be born, and if there was a hammer, there would be a girl. Also, if in the process of creating the heir a man wears a manly headdress, then a boy will be born.
Modern methods of planning the sex of the unborn child are far removed from those that were before. Now they have a scientific basis. The calculation takes the genetic predisposition, the food used before and during pregnancy, and, of course, the blood group of future parents.
Modern women are very popular conception by the method of calendar. This method is based on calculations by the calendar. The calendar method is based on scientific facts and in most cases will help to predict the sex of the unborn child.
How does it work? Everything is simple enough. Everyone knows that the female body works cyclically. The main task of this process is the maturation of the egg and its readiness for fertilization. This is called ovulation. Ovulation in women occurs approximately in the middle of a monthly cycle. At each it is individual. The most favorable period to get pregnant is two days before ovulation and a week after ovulation. You must correctly calculate and determine the duration of your ovulation. But this is only the beginning of all calculations.
As is known even from school practice, the sex of the child depends on how the chromosomes will unite during the fertilization of the egg. The combination of chromosomes XX belongs to the girl, and XY of the chromosome to the boy.
Calculations based on the calendar method for determining the sex of a future child are based on the theory of chromosome viability. The theory says that Y chromosomes, that is, men's, are more mobile, but less resilient. X chromosomes, on the contrary, are more sluggish, but more tenacious. If the sexual intercourse has occurred less than a day before ovulation or immediately after it, then the conception of a boy with a probability of 80% occurs. This is because, as already mentioned above, that the Y chromosomes are more mobile. If the sexual intercourse has occurred more than one day before the maturation of the egg, or a day after ovulation, then the probability of conceiving a girl is increased.
To the truth of this theory, scientists came through a lot of research. The data obtained from this study convinces us of the connection between the child's sex and the day when his conception takes place.
Now it is not difficult for you to calculate by the calendar method, when the girl will be conceived, and when the boy is. Remember, for this method the main thing is the exact definition of the day of ovulation. To determine the exact day of ovulation, you need to monitor the changes in the base temperature, observe the structure of the discharge. But today there is a more reliable way to determine the maturation of the ovum - these are tests for ovulation, which can be purchased at any pharmacy.
If a woman's ovulation process falls exactly on the middle of the calendar cycle, then she can be advised an easier way to plan the sex of the unborn child. In the odd years of the mother's life in even-numbered months, such as February, April, June, August, etc., the boy is more likely to conceive. And, accordingly, the probability of conceiving a girl in even years of life in odd months, such as January, March, April, etc., increases.
Of course, these methods do not give an absolute guarantee of determining the sex of the child. The female organism in itself is a very complex structure. Many factors affect it. If you really go to experiments, it is better to not find the calendar method.
