The Journey of Sexual Chromosomes
It often happens that fathers blame mothers forthat they can not give birth to the desired boy. But, if we consider the process from the point of view of biology, then the sex of the future child depends entirely on the man. The matter is that at conception two sex cells merge (men and women, respectively), and in each of them there is only half of the genetic heritage of an individual. That is why each cell contains two chromosomes that are responsible for a single sign (two chromosomes for the color of the eyes, the length of the hair, sex, etc.). Sometimes they are the same, and sometimes they are different. For example, a situation is possible in which the child from the brown-eyed father will get the gene responsible for the blue color of the eyes, because in fact he was in the father's gene pool, but successfully hid before the moment of conception. And if in the case of other symptoms it is difficult to say whether the chromosomes are different in the cell or the same, then it is known about the sex chromosomes to mankind reliably. A woman has two identical X-chromosomes, while a man has different X-chromosomes. One X, another U. Depending on which chromosome separates from the male cell, a certain sex of the child will be obtained. Accordingly, all calendars suggesting the planning of conception time for obtaining the desired result take into account the phases, when the separation of the desired chromosome from the DNA of a man is most possible. 
The basic principle of planning
All manipulations at the time of conception lead to,To give the spermatozoa of a certain type the first to reach the ovum. Scientists have found out that those that carry the male chromosome are more mobile and quick, but less tenacious. Spermatozoa with female chromosome, on the contrary, are heavy and slow, but can survive longer in unfavorable conditions. Our task is to make sure that one or the other is the first to reach the finish line. If you want a boy, then you need to strive to ensure that spermatozoa quickly meet with the egg and that those who are quicker survive. This will help deep penetration and powerful ejaculation. If you want a girl, you need to provide spermatozoa enough obstacles on the way to the goal. At the time of conception, you should not penetrate well and it is best to have sex regularly so that the sperm resource is depleted. Just want to say that no method gives a 100% guarantee of the result, it is only a generalized, centuries-old experience. If you want a guarantee, you better use IVF.
Tips for Chinese Traditional Medicine
Already in ancient times people knew how to determine sexa child by the date of conception. And the people's methods were all of their own. Basically, they were based on observation and analysis of the data obtained. And, nevertheless, the effectiveness of these calendars and tables was very high. Consider the Chinese table of conception of a child of a certain sex. It is based on two indicators: the age of the mother at the time of the alleged conception and the month in which sexual contact will be made. There is a small subtlety in determining the age of the mother. Within the framework of this conception calendar, it is not the number of full years of a woman that is important, but how many years ago she was conceived. Therefore, for an accurate calculation, add to your biological age 9 months - this will be the final figure, which should be guided in the table. Find the cage at the intersection of the mother's age and the month of conception. If it is pink, then you will have a girl, white - a boy. This method of determining the sex of the future baby has not too high accuracy of the forecast. And, nevertheless, they are still successfully used in China, trying to invariably give birth to a boy in the context of the "one family - one child" policy. However, there are some scientific confirmations of this method. It is known that younger moms often give birth to boys, as the table shows. 
The Japanese way
To calculate the sex of a child using Japanesecalendar, you have to work a little and carefully examine the two tables. In the first table, you need to match the birthdays of future mothers and fathers and find the number at the intersection of these data. After that, proceed to the next table. You should consider a column with the number you defined earlier. In this column, all 12 months are vertical - these are the potential months of conception. And in the middle of the table the scale of the probability of the birth of a boy or a girl is shown. The more signs "x", the higher the probability of conception of the child of the sex.
Astrological forecast
Another method that helps to reasonably approachconception, is the lunar calendar. It lists the best days for the child's creation of the lunar month. Note that the cycle of the moon consists of 29 days, and they do not coincide with the usual Julian calendar. Therefore, it is necessary to find out what day of the lunar calendar is in the specialized sources. The lunar calendar has helped people in many ways since ancient times. For example, it is widely known and confirmed empirically that plants are best planted in the initial phases of the moon.
