GMOGenetically modified organisms (GMOs) are a part of our diet, finding their way into many of the foods we eat. This might not be good news for couples struggling with infertility. A new study finds that GMO corn made rats sterile. While rats are one thing and humans are another, it’s probably a safe bet that GMOs shouldn’t play a part in your fertility diet.

The study, led by researchers from the Suez Canal University, revealed that by day 91, the rats fed GMO corn were sterile. This sterility was in addition to the organ damage they suffered to their liver, kidneys, heart and spleen. The study showed the kidneys of the male rats suffered the most damage (43.5 percent) while the kidneys of the females were slightly lower (30.8 percent).

The study is the latest of several that reveal GMOs need further investigation for their effects on human health. In every study, infertility of the animal involved is a common side effect of consumption of GMOs.

In 2013, a Russian biologist revealed that hamsters fed diets high in GMO soy (like that which is grown in the vast majority of fields in the United States) experienced a higher mortality rate and that the surviving adults suffered infertility.

In 2012, a French study from the University of Caen revealed that rats fed GM corn (identical to what is fed to humans and animals here in the United States) and trace amounts of Roundup (a weed killer made by Monsanto) suffered severe organ damage to their livers and kidneys. This damage appeared in as little as four months. To read more about this study, you can see the abstract here.

GMOs are unfortunately pervasive in the food you have available today. However, there are great ways to avoid them, too:

  • Look for the USDA Organic symbol. The organic standards do not allow the presence of GMOs.
  • The Non-GMO Project Seal of Approval. As a third-party organization, the Non-GMO Project approves foods that have been verified to avoid GMO foods.
  • 365 Everyday Value foods. The Brand, 365 Everyday Value Foods from Whole Foods, provides food that avoids GMOs

Other strategies include choosing foods that avoid the five high-risk foods: corn, canola, soy, cotton and sugar beets. These GMOs, however, are the ones most commonly included in packaged foods. Avoiding packaged foods and sticking to fruits and vegetables is always a safe bet for those trying to avoid GMOs.

When you are trying to conceive, your fertility diet and your overall health play an important role in your ability to overcome infertility. As more and more research reveals, your fertility diet should be one that avoids the potential health dangers that GMO crops impose on your fertility health. Choose organic or non-GMO-verified foods for yourself, and you will give your fertility the best chance possible to help make your dreams of family your reality.
