The reasons for the birth of conjoined twins

The birth of conjoined twins is extremely rare. Until now, scientists are unable to determine the indirect cause of this disease. Initially it was assumed that cell division in the womb is not uniformly or partially (up to 12 days after conception). Most often this pathology occurs in identical twins and in particular suffer from the girls. Found this flaw in 4 times more often than boys.

Statistics show that in live there is only one pair of the four. The rest die at birth or are born already dead. The difficulty is that to anticipate the birth of twins with this pathology is impossible, because it is very difficult to identify initially signs of Siamese twins.

The twins are connected to different parts of the body. Scientists classified according to this criterion: TeraCopy - twins, fused breast cells (a majority of them - about 35 %), omphalopagus twin fused line from the chest to the waist ( about 30 %), pagepage - fused spins ( about 19 %), craniopagus - twins fused heads ( forecast such unfavorable ankylosis of the separation of these twins is not possible).

Contribute to the fusion of many factors. It can be genetic disorders, various toxic poisoning and even environmental impact. Often genetic disorders do not allow normal functioning of the body and to perform properly their functions. It is not correctly allow the cells to divide, which leads to the birth of fused twins.

Scientists of the Institute in Frankfurt, studying abnormalities in the anatomy and development, concluded that genetic abnormalities do not play an important role in the development of this pathology. They argue that such twins are born due to mental illness. As the example was given of a syndrome of a split personality. Experimented on monkeys. Was the study that pregnant female monkeys kept in stress. Later in their offspring dominated the percentage of fused cubs.

Birth of Siamese twins are surgically, because the Union does not allow to be born babies the natural way. Meet the twins, one of which is like a parasite on the other, using his health.

The separation of children is possible, but requires highly qualified technologies.
