One of the main questions of future parents is determining the sex of the child. There is an opinion that all men dream of a son, while women, on the contrary, want a daughter. But in reality, all this is purely individual.
It would seem, what difference does it make who is born? The most important thing is that the baby is healthy. Nevertheless, when pregnancy comes, I want to quickly find out who will be, a girl or a boy?
There are many methods for determining the sex of a child at an early stage. Often, their predictions are correct, but official science has not yet recognized any method as 100% reliable.
Chorionic biopsy is the most accurate such method today with almost 100% guarantee. It is possible to determine the sex of the child from 7 weeks of pregnancy. But this method is mainly resorted to only for medical reasons, in some cases it can lead to the development of serious complications, even termination of pregnancy.
Another very reliable method that allows you to determine the sex of the child already at 12-14 weeks is to determine the sex by the frequency of his heartbeat. Many gynecologists use this method and rarely make mistakes. Typically, a fetal heart rate of more than 140 beats per minute corresponds to a girl. If less, then the boy.
Perhaps the most common and official method for determining the sex of a child is ultrasound. In any case, this is possible no earlier than 10-12 weeks of pregnancy. The child may exhibit peculiar false signs. More accurate data can be obtained for a period of 23-25 weeks. But ultrasound, unfortunately, does not give you a 100% guarantee.
However, there are cases when, for example, an ultrasound scan is not possible for medical reasons. In such a situation, you can turn to folk methods, one of which is sex determination by date of conception.
A woman can only become pregnant during ovulation. Sperm can be stored in the female genital organs for up to 96 hours. Because the life expectancy of male spermatozoa, carriers of the Y chromosome is less than carriers of only the X chromosome (female), the likelihood of conceiving a boy increases sharply on the days of ovulation. But this is also not a 100% method.
A very common technique for determining the sex of a child at an early stage for blood renewal. The blood in women is renewed every 3 years, in men - every 4 years. If a woman has a negative Rh factor, then vice versa. Whose blood will be "younger", of that sex and the baby will be born.
The interesting point here is the frequency of having sex. If a man had prolonged abstinence until the moment of conception, most likely there will be a girl. This theory has found its scientific explanation: the more mobile "male" spermatozoa do not live long, so in the sperm of a man who has not had sex for a long time, the number of tenacious "female" spermatozoa is increased.
There are many formulas among the people for determining the sex of an unborn child. One of them looks like this: 49 - X + 1 + Y + 3, where X is the father's age, and Y is the month of conception. If the answer here is an even number - expect a boy, an odd number - a girl.
In general, ultrasound, as a way to determine the sex of a child at an early date, is the most reliable of the safest methods. Scientists continue to search for new approaches to solving this problem. One of these areas is innovative tests to determine the sex of the unborn child. They have not yet received widespread practical application, and their accuracy is also not 100%.
Of course, today there are many methods for determining the sex of a child at an early stage. Which one to use is your legal right. But so that you do not choose the main thing, that the baby is desirable, healthy and beloved.
