Twins occur about once in every ninety live births and the exact rate varies globally coupled with ethnicity and heritage. The highest rate of twinning could be due to the following reasons:
High estrogen levels cause more ova to mature and be released due to dietary habits as caused by consumption of excess yam in the diet.
Identical twins, technically known as mono zygotic, are formed from the fusion of one sperm and one ovum. This one fertilized egg, for unknown reasons, splits into two identical halves which develop separately into identical babies. Physically, they are the mirror reflections of each other and are always of the same sex.
Fraternal twins or dizygotic twins are the result of fusion of two ova from one ovary or both ovaries with two sperms. The children may look similar or just as different as other normal ones. High incidence of twin birth rates in particular place for a long period of time, is altogether, a different matter of medical wonder. It needs special attention and research work.

Dr.
Krishnan Sribiju, who is researching on the Kodinhi twins for
sometime, believes the real number will be be far higher- between
300 and 350 twins within the village boundaries.
Kodinhi
has,surprisingly, 45 twin births for every 1000 births whereas the national and
also Asian rate of twin births is roughly 4 out of 1000 births. It is
also noted that twins are born to more mature women, who are normally over 5 feet and
three inches in height. The
majority of twins in Kodinhi are identical twins of same sex.

In
the past five years alone, it is observed, that up to 60 pairs of
twins have been born - with the rate of twins increasing year by year
and in the past ten years the number of twins in Kodinhi has, for unknown reason doubled.
Researchers have yet to come up with a possible, acceptable biomedical theory for this strange phenomenon that occurs only in this village and not in surrounding villages, not even in fringe villages bordering this village.
Yet another matter of interest is villagers allege that the twin phenomenon is not a recent one and has been occurring since 1949. That, both men and women marrying outsiders – from other villages still report high incidence of birth of twins, has surprised the researchers and is more of a riddle
that has remained unsolved.
Igbo-Ora in Nigeria is yet another place which has the highest rate of twin births in the whole world. As per a study conducted by an English Gynecologist, Patrick Nylander, an average of 45 to 50 pairs of twins per 1000 live births were recorded during 1972 and 1982 in Igbo-Ora. Researchers believe eating habit plays a major role in the birth of twins here. However, in the case of Kodinhi, people here and other parts of Kerala have similar food habits. So, comparison can not be made based on dietary habits.
Candidi Godoi, Brazil, Latin America has a large number of twin births. In the case of Kerala village, the enigma is yet to be solved. May be an offshoot of this mystic world!!
