Indian Village Of Twins A Mystery

A small village in India has about a hundred pairs of twins (mostly the same sex) and 90% of them were born in the last 20 years. No one can explain this phenomenon, although I have a theory that might or might not be correct. I recall hearing some while back that the in a report published in the current issue of the Journal of Reproductive Medicine, researchers linked recombinant bovine growth hormone (rBGH) with this rise in twin birth rates. The study shows how rBGH, a synthetic growth hormone used to increase milk production in dairy cattle, increases ovulation in humans and persists in the body after entering via digested food, particularly milk. Monsanto's controversial hormone has been banned in almost every industrialized country in the world,but I do not know if this is the case in India. The ban was due to scientific evidence indicating that the milk from injected cows contains more pus, antibiotic residues, and IGF-1, a potent cancer tumor promoter.
Now Hindus do not eat beef because they consider the cow sacred but they do drink cow's milk after they are weaned which is why they call the cow "Go Mata" or "Mother Cow". I think that people should try to look into the quality of these people's milk supply, if it happens that their cows started using growth hormones around twenty years ago, it could be a possible explanation for the unusually high rate of twin births.
