However until now use hormonal contraception of no more than 10% young women, while all sexually active teenagers know about such method of protection from pregnancy almost. Teenagers do not wish to apply hormonal preparations, referring to the until now saved opinion about their harm for a health, on relative costliness of method. The not unimportant value has incomplete (or negative) information of teenagers about a similar method of contraception.
It is necessary, however, to mark that the prolonged preparations, in spite of failings described higher, makes sense to recommend to the unhappy girls-teenagers socially, in that number by an abusing alcohol, drugs, being in durance vile.
The combined oral contraceptives are more reliable and convertible facilities of protection from pregnancy, than preparations with progestagen. The theoretical and real index Perl of modern COÑ makes 0,040,07 and 0,30,9 accordingly.
Presently in the world is counted about 500 different COC. For comfort of determination of properties all existent combined oral contraceptives are classified on the type of progestagen component. The presence of different classification signs was the result of the protracted, almost semi-centennial history of the creation COC.
Modern industry of hormonal contraception allowed substantially to change the structure of testimonies and contra-indications to the application COC, in that number for sexually active teenagers. Hormonal preparations it is possible to recommend to use, both urgent measure of warning of pregnancy and permanent highly reliable method of contraception and planning of procreation.
Information of teenagers that postcoital contraceptioncan be appointed by a doctor only, appears by an important moment in elucidation of necessity of selection of method of regular protection from conception. The examination complemented by the necessary inspection allows objectively to estimate the state of woman taking into account its health and results of application of postcoital contraception.
Irregular menstruations can not behave to contra-indication of reception of hormonal preparations. Opposite, setting of modern COÑ provides the control of duration of cycle and prophylaxis of origin of the uterine bleeding.
Low growth also must not be examined by contra-indication of setting of hormonal contraception at sexually active girls-teenagers. Assertion that the reception of hormones for contraception stipulates acceleration of pubescence and closing of areas of growth of bones has under itself no warrant. Biological age at beginning to menstruate girls with growth below 150 sm, as a rule, coincides with passport age.
Surplus of mass of body also must not stop a young woman from the use of modern COC. It appeared that the micro dosed out contraceptives from progestagens 3rd generation practically did not influence on mass of body.
It is interestingly to mark that the protracted use COC during a intergenetic interval and presence of desirable amount of pregnancies creates operating of the reproductive system conditions, which are similar to such at the women never protected from pregnancy and having 10-12 children reared by a breast. The last variant of reproduction is small acceptable to the modern stage of development of society, in spite of the fact that is considered the best method of prophylaxis of origin of cancer of ovaries and mammary glands.
