The boy or the girl? Whether it is possible to affect a sex of future child? On what the sex of a child depends

What it will be? What will be eyes, a nouse to whom our kid will be similar? For whom to us to wait, the boy or the girl? What can go not so? Whether I will lose the child? Agree, you more than once thought of it or will think, when time will come. Whether to define to you a sex of a child and that with it can there will be important questions. But about all one after another.

The floor yet not born child depends on that pair chromosomes which passes to the child from a seed of the father and jajtsekletki mothers, namely - from sexual chromosomes. In jajtsekletkah the female sexual chromosome which because of its form name H.Spermatozoidy's chromosome contains only chromosomes Y can be carriers as chromosomes H, and. As a result of merge of chromosomes HH there is a girl, in summary merges of chromosomes ХY - the boy. And though the embryo sex is defined from the very beginning, till the moment of formation of genitals development of the boy does not differ from development of the girl.

The boy. Till sixth week embrionalnogo no distinction between embryos of the boy and the girl is present development. Only now chromosome Y starts to interfere with development actively: the basis of man's genitals is pawned, are formed jaichki, development of hormones begins. Formed in jaichkah the hormone - testosteron - stimulates formation of external man's genitals and simultaneously interferes with formation of the female. Already at this stage there are cages which begin to develop subsequently spermatozoidy. These are cages from its part even more accelerate development. At favorable position of an embryo in a uterus at ultrasonic research it is possible to consider its genitals already on the twelfth week and by that to define a fruit sex.

The girl. If caused fertilisation spermatozoid was the carrier of chromosome H absence of chromosome Y causes development in a fruit of female genitals: jaichnikov, a uterus, vaginas. External genitals simultaneously develop: the big and small sexual lips and klitor. Approximately on two weeks later, than jaichki boys, jaichniki female sexual hormones start to allocate: estragen and a progesterone. To define a sex of girls at ultrasonic research it is a little bit more difficult.

Genitals of the future child start to develop already on the eighth week of pregnancy and are visible at ultrasonic research already on the twelfth week of pregnancy. But it does not mean, that the error is excluded. The fruit constantly is in movement, therefore the result of research can appear incorrect. If in the beginning all looks how at the girl it at all does not mean, that subsequently will not be found out, that it was the boy and on the contrary. Such errors are not too frequent, but it is not necessary and to exclude completely their probability and too early to adjust itself on a birth necessarily only the boy or only the girl, especially if the verdict of the doctor has been taken out only on the twelfth week. Wait for following inspection to receive more exact answer.

Whether it is possible to affect a sex of future child? Spermatozoidy-carriers H - chromosomes are more viable, and spermatozoidy-carriers Y - chromosomes are more mobile. Therefore if sexual intercourse is made before ovuljatsiej the birth of the girl as the probability of survival Y - chromosomes in these conditions is insignificant is more probable. If sexual intercourse occurs after ovuljatsii the boy as Y - chromosomes reach jajtsekletki faster, most likely, will be born. However all these statements still require serious scientific proofs. Though, the majority of embryos of a male agrees to the statistican, however boys is born all the same less, than girls (accordingly 49,5 % and 50,5 %). The conclusion From this follows, that germs of girls are more viable and less often perish as a result of abortions, they it is less, than male germs, are subject to various harmful influences. Possibly, same that women in general are more viable men speaks also. Therefore, according to all to the same statistics, the stronger sex all the same is not man's, but female.

Today in the countries of the European cultural tradition legislations of the democratic states proclaim equality of men and women. Therefore it is difficult to us to understand, how today in some countries of the woman can be considered as the lowest being and as some future mums go on pregnancy interruption when learn, that at them the girl will be born. So quite often happens, for example, in China where the population is especially high and where the state tries to contain its further growth in every possible way. The law limits quantity of children in a family, and many women at whom should the girl will be born, its birth any more do not want. Discrimination and the oppression of women fixed by the law and remains presently in the nature of things in many countries of Asia and Africa.

During the period from conception till the birth of the child for a normal current of pregnancy presence of many factors is necessary. Unfortunately, sometimes pregnancy comes to an end with an abortion. Its reasons can be the most different, but they can be united in following groups: defects impregnated jajtsekletki, the physiological or psychological processes occurring in an organism of mother, and external influences (traumas, drugs, etc.) . For example, the abortion can occur owing to genetic defects jajtsekletki which are connected with the years parents. Very often early pregnancy come to an end with involuntary abortion. The abortion reason can become and heavy disease of mother, and also anatomic anomalies or the hormonal infringements interfering an attachment plodnogo of egg to a wall of a uterus. However such physiological phenomena accompanying early terms of pregnancy as a nausea, weariness, etc., should not disturb future mums. Even if the previous pregnancy has ended with an abortion it yet an occasion to despair. Only in case of habitual abortion it is necessary to mark attentively all possible indispositions as their reasons can be more serious.

Spontaneous abortion on early terms of pregnancy usually happens is connected with anomalies jajtsekletki. It means, that the embryo has the heavy, genetically caused anomalies interfering its survival. If all has been made for a normal current of pregnancy in case of an abortion it is possible to assume, that an embryo, or a fruit, was really impractical. In this case has worked the mechanism which the nature has started to interfere with development of heavy genetic anomalies and their further transfer to following generation.

Remember! In first three months of pregnancy the nausea and dizziness are frequent. It is normal. But in case of bleedings or pains we advise to you to address to the doctor. If you consider, that your indispositions are typical for pregnancy, consult to the gynecologist. The major means of struggle against abortion threat - rest!
