According to statistics...

According to different statistics held by different scientific groups from different parts of the world, nowadays there are more than 70-80 pairs of twins in the world.

The number of twins that are born is increasing. If to compare the modern number of twins that are born with those in 60-s, the percentage increased in 2.5 times. Doctors talk a lot about it, but the main their explanation is the achievements of medicine in the sphere of treatment of sterility.

1/3 of all twins burn in the USA are alike one another and in Japan 2/3 of all twins are alike one another.

It is interesting the theory of one American doctor who made the statistics of the number of twins in a few years. According to him the number of twins would decrease. But when he made up his theory, there were no good methods of treatment of sterility and female problems. That is why in fact it is possible to say that medicine saved twins.

If you are a non-identical twin you have 6 chances of 100 to give birth to twins. If you are an identical-twin you have the same chances to give birth to twins as any ordinary woman. That makes 1-2.5 chances of 100 in dependence on hormone substances. If your mother is non-identical twin your chances are higher than the average one. And if your father is non-identical twin then the chances are average and the same as if your husband was the twin or there were twins before in the family. If somebody of your parents is identical twin that won't influence your chances to give birth to twins.
