This is a youtube video from January 2012, (12:46).
A farmer in Iowa who has farmed since the 1970s, and started using Genetically Modified corn with his hogs in 1997. In 2000 approximately 80% of his sows experienced false pregnancies, in which they appeared to be pregnant but produced no young. Several other farmers in his area were having the same problem, and when they compared notes, the only thing they had in common was the brand of GM corn they fed their pigs. Yet, the seed company blamed the farmers and refused to take any responsibility. This guy lost his farm because of it.
Infertility is a growing problem and the pervasiveness of genetically engineered foods is likely to be the reason. From what I’ve heard, canola oil (aka: rapeseed), soy, soybean oil, corn and corn syrup are the culprits. It seems that all of them are in nearly everything you eat. They are everywhere!
