How to warn barreness

Development of sexual system of the girl, since 5th week эмбрионального the period, proceeds long time, to 16—18-летнего age. For 5th weeks эмбрионального developments appear primary sexual cages which move in a sexual fold and form яичник or яичко. This process depends on an embryo sex, i.e. From presence or absence of a Y-chromosome in its cages. If the cellular floor man's (there is a Y-chromosome) primary sexual cages settle down in the centre of a sexual fold and is formed man's sexual gland. If the cellular floor female (is available two H-chromosomes) primary sexual cages settle down on periphery of a sexual fold and is formed яичник — female sexual gland. It is necessary to notice, that man's sexual gland begins hormonal activity already in эмбриональном the period, at the age of 6—7 weeks эмбрионального developments. Under the influence of hormones formed in it man's genitals are formed. Formation of female genitals occurs at those embryos which sexual glands do not form hormones of man's sexual gland (андрогенов and a hormone primary эмбриональной man's sexual gland). Scientists believe, that the female sexual system is formed in the absence of influence of sexual hormones.

Nevertheless in яичнике in эмбриональном the period there are considerable transformations. Primary sexual cages in it intensively share. Thereof reproduction from 30—50 primary sexual cages by the pregnancy end in яичниках the newborn is from 200 thousand to 1,5 million sexual cages in spite of the fact that simultaneously to processes of reproduction of cages there is also a  destruction of their part. Processes of formation of sexual glands except internal эмбриональных factors (full value of the sexual chromosomes received from parents) are influenced also by environment factors, i.e. a condition of a parent organism. Heavy, especially virus diseases of mother, toxic influences (alcohol, the drugs, some chemical substances, antibiotics) in the first weeks of pregnancy can break correctness of formation of sexual gland of an embryo, and it in the subsequent can lead to barreness.

Uterus formation, маточных pipes and a vagina also occurs in the first trimester of pregnancy, i.e. Till 12—13 weeks эмбрионального developments. At infringement of this process the uterus and a vagina can not be formed at all or be generated incorrectly. For example, there can be 2 uterus and 2 vaginas, or to be formed the defective short vagina which does not have an external aperture that leads to absence of outflow from a uterus. Such pathology is shown, as a rule, at the age of 13—14 years when at the girl function begins менструальная, and менструальное the separated cannot find an exit outside. It accumulates in a vagina and in a uterus, stretches them, is thrown through маточные pipes in a belly cavity, causing irritation брюшины and the strongest pains in a stomach. Treatment only operative — formation of a vagina for outflow realisation менструального separated.

It would be desirable to remind once again to the women expecting a birth of the child, importance of observance by them of hygiene and preservation of the health. Truly, preservation of the health, conducting a healthy way of life is pledge of a birth of the healthy child. For example, disease of parents by the milkwoman, a gonorrhoea or a trichomoniasis last weeks to pregnancy leads to infection of the child, especially girls, these diseases in the course of sorts.

The majority of parents, understanding importance of hygiene, regularly bathe the baby as children love these procedures. But then bathings become more rare, the toilet of external genitals is carried out too far not regularly. And suddenly at this age appear allocation from a vagina, reddening in the field of external genitals. More often these phenomena are connected with insufficient hygienic leaving. In a vagina of the girl which has no on the anatomic structure external запирательного жома, environment microorganisms get. At penetration of pathogenic species of microorganisms into a vagina there is an inflammatory process. Thus appear allocation (bleach) also irritation them skin of external genitals. Pathogenic microorganisms can be brought каловыми in weights, hands, clothes, can get at bathing in the polluted reservoirs, etc. Infringement of the general condition of the child, chronic diseases ротоносоглотки, allergic diseases, metabolism infringements can promote occurrence of inflammatory process in a vagina of the girl. Therefore so observance of a healthy way of life, hygiene at the child already since a birth is important. The eutrophy, закаливание, regular moderate physical activities, observance of rules of hygiene — all is preventive maintenance of the big number of diseases, including gynecologic.

Very important period of development of the person is пубертатный the period, or the period of sexual development covering age from 10 till 17—18 years. At this age especially intensively ripens and development of sexual system comes to an end.

It is necessary to remember, that яичник is not only body in which remain and ripen яйцеклетки, giving rise to a new life, but also the body forming sexual hormones. These hormones are necessary for creation of optimum conditions for maturing яйцеклетки, its fertilisations, for development of an embryo, growth and a birth is healthy about го the child. Other glands of internal secretion help with creation of such conditions яичнику also. Difficult interaction will organise them and the central nervous system co-ordinates.

It is necessary to tell, as puberty is supervised by the central nervous system. It begins only at achievement by the girl of certain level of physical development. For example, it is established, that the weight of a body should be not less than 45 kg.

The control and regulation of sexual system are carried out by means of the substances formed in a bark of a brain and in subcrustal structures. It катехоламины, опиаты, рилизинги and so forth So-called гонадотропный the rilizing-hormone is allocated with nervous cages of a subcortex. This hormone makes active formation and an exit in blood гонадотропных hormones of a hypophysis which directly stimulate function яичника. And so, formation гонадотропного a rilizing-hormone increases to the beginning of the period of sexual development Thereof concentration гонадотропных hormones under which influence formation of female sexual hormones of a-estrogen — in яичниках amplifies increases. The formation and allocation increase in blood of an estrogen leads to transformation of the girl into the girl. Mammary glands start to develop, the uterus grows, the figure changes, adjournment of fat in the field of hips amplifies.

Further the cyclic type of allocation of hormones, characteristic for a female organism is formed. It consists that within 2 weeks an estrogen is allocated basically, then within 2 next weeks allocation in яичниках a progesterone prevails, the Progesterone is formed in significant amounts only after an exit from яичника mature яйцеклетки. Cyclic secretion яичниковых hormones prepares a uterus for reception яйцеклетки and promotes high-grade tearing away of a mucous membrane of a uterus during time менструации.

Correctness of a current of these difficult cyclic processes in an organism of the girl is regulated by the central nervous system. Therefore considerable psychological overloads, parts about nervous shocks, stresses, the excessive intellectual loadings especially connected with occurrence of feeling of shortage of time, can promote infringement of recurrence of regulation of function яичников. It will lead to maturing infringement яйцеклетки, to infringement of development of a mucous uterus. Therefore at girls пубертатного age we so often observe маточные bleedings and irregular менструации. Quite often such infringements arise after the disease transferred by the girl. It can be ОРВИ, a flu or any other disease proceeding with a heat. For preventive maintenance of infringements менструального a cycle after such diseases to expediently ill girl to give the increased quantities of vitamin C in 2nd half менструального a cycle and a complex of vitamins B in 1st its half.

Гонадотропная function stimulation яичников, amplifying in puberty, can promote growth of tumours and опухолевидных formations in яичниках. It кистомы and кисты яичников. They appear and start to grow in пубертатном the period. However are quite often found out much later, only after survey by the gynecologist. At the girls conducting a mobile way of life, it is quite often observed перекрут legs кисты, that causes sharp inflammatory process in a belly cavity and dictates necessity of the emergency operative help. At operation in such cases it is necessary to delete all яичник. Therefore we, children's gynecologists, insist on necessity of gynecologic survey of girls пубертатного age. Timely detection кисты яичника allows to make removal only кисты and to keep яичник.

Enough widespread opinion, that менструации at the girl should be painful. Really, painful менструации at girls are observed often. Nevertheless studying of the reasons of this phenomenon shows, that is frequent to it conduct inflammatory processes of internal genitals and wrong development of a uterus.

Many girls, wishing to keep leanness or to grow thin, not simply limit a food allowance, but also cause vomitings, drink a depletive. Uncontrolled restriction of a food causes sharp decrease in appetite, the weight of a body decreases. The girl reaches desirable result. However against loss of weight of a body, at its approach to 45 kg, disappear менструации, that is the terrible symptom specifying in considerable infringements in regulation of functions of sexual system. We consider this phenomenon as the protective reaction of an organism connected with impossibility more to lose fibers and elements of blood with менструацией. Moreover, at such decrease in weight of a body cyclic allocation гонадотропного a rilizing-hormone and гонадотропинов, maturing яйцеклетки stops, formation of hormones and in яичниках decreases. There are so deep infringements, what even the increase in a food allowance and an increase of weight of a body far and not always at all lead not at once to restoration of function of sexual system.

These and some other troubles could be avoided, if parents in time and correctly conductor with the girl of conversation concerning sexual education.
