However, even in our age of high technology, it is not yet possible to predict the sex of the future baby with a 100% probability. Only as a comfort, printed and online publications offer planning couples to use "near-scientific" and folk methods, such as the calendar for the future child's sex, the ancient Japanese and Chinese fertility tables, the method for blood renewal , a special diet for a boy or girl, and others, up to end is not grounded methodology. All these methods are very relative, but, nevertheless, they have their supporters.
Let's consider the basic principles and features of the work of some of them.
Pregnancy and child planning calendar
Many future mothers and dads use a special calendar when planning a pregnancy, which allows you to determine the sex of the child by the date of conception. The method is based on the characteristics of female and male physiology, factors such as menstruation days, ovulation, frequency of sexual contacts and much more are taken into account. This is one of the known methods, which has a scientific background.
Everyone knows that conception is a complex multilevel process that is preceded by the release of the female sexual cell (ovulation) and the entry of spermatozoa, carriers of the sex gene, into the vagina. Male gametes with the Y-chromosome, which is responsible for the birth of the boy, are more mobile, but less viable, so they quickly die in the acidic environment of the female reproductive tract. Carriers of the X chromosome, responsible for the birth of a girl, on the contrary, can stay in the vagina long enough. Considering the above, the conclusion suggests that the most important factor, from which the sex of the future child will depend, is the date of the fateful sexual intercourse. More precisely: before or after ovulation, intimacy took place. In the case when sex was a few days before the release of the egg is likely that the girl will be born, and vice versa on the day of ovulation and later increases the chances of Y-chromosome carriers the first to reach their cherished goal.
That is why couples planning to conceive a child of a certain sex and relying on the pregnancy calendar, you need to know the date of ovulation.
Japanese Child Conception Calendar
Admirers of ancient Japanese wisdom will probably be interested in another method of determining the sex of a future child with the help of a calendar, this is the so-called Japanese table (more precisely, two tables). This method is based on the beliefs of the Japanese people in the hidden meaning and significance of the date of birth of a person, and its fundamental role in the fate of each of us. Astrological knowledge and the study of horoscopes were also taken into account when compiling the tables. Nowadays everybody can use the Japanese calendar of conception. In the first part, a special number is determined at the intersection of the months of the birth of the parents. In the second part of the table, the figure obtained is compared with the date of the alleged or already completed conception. As a result, the sex of the unborn child is determined. As far as this method can be considered reliable, each pair will decide for themselves individually.
Chinese calendar of conception of a sex of the child
Not less popular is the so-called Chinese table, which harbors the experience and knowledge of more than one generation. With her help, many couples managed to predict the sex of the baby even before conception. In addition, the Chinese table is easy to use: on the one hand, the number of full years of the mother at the time of conception is indicated, on the other - the month in which it is planned, at the intersection of these two values, the sex of the future child is determined. What is the essence of this technique is not fully understood, some suggest that the method is based on the lunar calendar, others argue that the system is nothing more than the result of many years of research on establishing a connection between the age of the mother and the month of conception.
However, do not forget that the predictions of the Japanese and Chinese tables can be misinterpreted, because in our countries the numbering of the months and the age of the mother, which takes the count directly from conception, and not from birth, can differ.
