The twins are two people who came from the same womb at the same time. Almost every type of species on this earth can produce multiple births at the same time. The twins are very rare, representing approximately 1.2% of all human births. In short, one in every eighty births of twins. The birth of identical twins is even rarer, with a capacity of 250 births. Pairs of twins, two girls and a boy and a young girl.
Birth of twins can be different according toseveral factors. Some ethnic groups and people have been found in some places, a greater number of twins. Use of fertility drugs is also supposedly a reason for birth of twins, how do these drugs hyperovulation (multiple release of eggs). Thus, women who had fertility treatments tend to have multiple pregnancies.
Genetic factors are also likely to play a role in multiple pregnancies. Women who are aged between thirty and forty and aabove-average height and weight are also likely to give birth to twins. Women, the number of previous pregnancies and those who have recently stopped oral contraceptives was to give birth to several children.
The twins can be divided into several types: non-identical twins or fraternal twins (not identical), the same or identical twins (one egg that splits) twins disappear (if you can not survive the fetus), Siamese twins (twins identical with the bodies together in a site),parasitic twins (a fetus depends on the other for survival) (each a mirror image), twin mirrors and miscarried twins. The twins have compared a shorter gestation period of about 36 weeks to 40 weeks for an individual child.
Twins, though identical, have different personalities, it would be at least a slight difference in them to be. You can, however, the same brain waves. Some people also believe that twins have their own language "twin" through which theycommunicate with each other.
Twin pregnancies are usually difficult, because there is more weight as well as the placenta and amniotic fluid additional. One or both twins are in a perfect location in the uterus because of limited space. One or both can come down and walk with them first. The twins are also smaller and weaker than normal children at birth. The majority of births are two problems.
These days there are magazines, broadcasts, and allWeb sites dedicated to the twins. These contain useful information, facts and curiosities about twins who also useful for mothers, the twins are expected.
