Since that moment when it is already precisely known that the man and the woman shortly will become parents, they by all means want to know a sex of their long-awaited kid. For such cases still in the ancient time thought out ways of obtaining information who in family will be born.
National methods
The very first way of sex determination of the child was "a method of the hammer and axe". At night before conception one of parents put the axe under a pillow that the girl, the hammer was born – for the boy's birth. Today it is possible to call this way very dangerous and unacceptable for definition or forecasting of a sex of the kid.
In Russia the sex determination method was widely widespread on a wedding ring. The pregnant woman held on a suspension a wedding ring over a palm, and it started moving. On the nature of movements of a ring defined a sex of future fumes. Circular motions of a ring corresponded to a female, cross movements – men's.
The Czech psychiatrist Eugen Jonas offered own method of sex determination — by position of the moon in zodiac signs at the time of conception. If the moon in the air or fiery sign — is born the boy, otherwise — the girl.
Often key method mentions meet. This way works if house find a key with a round head and a long leg, will put it on a table, and the pregnant woman will approach and will undertake one of parts of a key. If the woman in labor lifted a key for a round part – there will be a girl if for a leg – the boy.
There is a way of sex determination of the child on age of future mom at the time of conception. Pays off step by step. Of the number of full years number 19 is taken away, then estimated month of childbirth increases. To January there corresponds number 1, to February — 2 and so on. Having calculated, estimate result - if number even, wait for the girl, odd – the boy.
Modern methods
The methods based on modern technologies, for example, by means of a blood type are more reliable. For this purpose the blood type of the man and woman – future parents is defined. Information on a Rhesus factor is important. If parents have both the first blood type, at any Rhesus factor they will give birth to the girl. Also will be if both of them have the second blood type, the third or fourth. And here if their blood types do not coincide, then most likely that the boy will be born, but here it is necessary to study more carefully also a ratio of Rhesus factors.
It is known that Y-spermatozoa (that is men's) are much more sensitive to low temperatures, than X-spermatozoa. On the basis of it apply cooling or warming to receiving the necessary sex of the child.
There is one more way of sex determination by birth. It is known that blood has property of stage-by-stage updating. At men this updating happens once in four years, women have once in three years. Therefore if blood was updated for dad later, than at mom, expect the boy and vice versa. The method of ultrasonography (ultrasonography) is most reliable. When the term of pregnancy is more than twenty three weeks, on planned ultrasonography at the doctor it is possible to take an interest about a sex of the child. During this period the kid is very mobile and, most likely, will open a riddle who is he such.
