Pregnancy Over 40, Fertility and GMO'sI don't know much about genetically modified crops, but I do know that their safety has been questioned.
I also know that, many processed products already contain genetically modified ingredients. Even the "health food" stores are carrying these products. See more here:

This article talks about how these crops can affect fertility. Read more:
The work was done at the University of Vienna, using a GM maize hybrid line called NK603 x MON810, which has two copies of the RR gene in it, each copy with its own, different promoter sequence, as well as the MON810 gene. In one of the very few long-term nutrition studies conducted so far with an approved GM product (2), it became apparent over a period of 20 weeks that the fertility of GM corn fed mice was seriously impaired, with fewer offspring than mice fed on non-GM equivalent material. In a multi-generational trial, mice fed with GM maize had fewer offspring in the third and fourth generations, and this difference was statistically significant.

Mice fed with GM-free corn reproduced more rapidly. In a series of carefully-controlled trials, it was also discovered that there was a statistically significant decrease in litter weight in the third and fourth litters of mice in the GM-fed group as compared to the control group.
