The new theory of formation однояйцевых twins is offered at medical conference in the French Lyons. As physicians consider, this theory will promote creation new the technician of restoration of reproductive functions of people. By means of specialised technics and the software doctors led by doctor Diana Pejn photographed each 2 minutes 33 embryos, is artificial grown up in clinic of reproduction Мио in Japan. Thanks to this technics it was possible to understand in details development of embryos-twins at the earliest stages.  As a result of supervision it is established, that formation process однояйцевых twins starts to occur after the embryo is in special way divided. This division occurs at level of the cages-predecessors containing the basic genetic materials. And each of such cages contains half of material. That is the same genetic material from the different parties of an embryo is divided on two parts, and further there is a development of two different germs.
Also in photos received in laboratory conditions, scientists observed two ярковыраженных the centre of weight of a cage in embryos from which twins then developed. As a result, viable there were 26 embryos from 33, and 2 embryos have started to share characteristic way for twins. According to doctor Soren Zibe, the expert in a reproduction from University of Copenhagen, the new technics explains just a principle of occurrence of twins. After all till now physicians assumed, that process of formation of twins begins already at an embryo stage when actually it already starts to be attached to a uterus for the further development. In general, by data statisticans, at natural process of fertilisation only in 3 cases from 1000 steams as a result receives twins, but in case of artificial fertilisation this percent much more above - 21 case from 1000. The reasons of such phenomenon for experts also managed to be defined. The matter is that laboratory conditions strongly enough differ from natural conditions. Therefore the embryo also starts to share more actively to reproduce natural conditions of a uterus. Thus, it leads to development of pairs the proto-cages leading to occurrence of twins. Also according to Пейн, on occurrence of twins very big initial number of factors - concentration of gases, a fermentation or balance of elements influences.
