Genetically Modified Foods Already Linked to Reduced Fertility

Genetically engineered (GE) corn and soy have already been shown to reduce fertility in animals, and glyphosate, the active ingredient in Monsanto’s weed killer Roundup, which is heavily used on GE crops, has also been shown to alter fertility.

For example, female rats fed GE (Roundup Ready) soy for 15 months showed significant changes in their uterus and reproductive cycle, compared to rats fed organic soy or those raised without soy. According to researchers, if women experience similar changes in the uterus lining and altered hormonal levels, it might increase the risk of retrograde menstruation, in which menstrual discharge travels backwards into your body rather than through your uterus. This can cause a disease known as endometriosis, which may lead to infertility.

The disorder can also produce pelvic and leg pain, gastrointestinal problems, chronic fatigue, and a wide variety of other symptoms. Genetically modified soybeans are called Roundup Ready.

They contain a bacterial gene that allows the plants to survive a normally deadly dose of Roundup herbicide. Although the spray doesn’t kill the plant, its active ingredient, glyphosate, actually accumulates in the beans themselves, which are then consumed by livestock and humans. There is actually so much glyphosate in GE soybeans that when they were introduced, Europe had to increase their allowable residue levels 200-fold!

Glyphosate Poses Risk to Female Reproductive Health

Although there are only a handful of studies on the safety of GE soybeans, there is considerable evidence that glyphosate—especially in conjunction with the other ingredients in Roundup—wreaks havoc with the endocrine and reproductive systems.

Glyphosate throws off the delicate hormonal balance that governs the whole reproductive cycle. It interferes with aromatase, which produces estrogen, and it’s also highly toxic to the placenta in pregnant women. In a 2009 French study, scientists discovered that glyphosate can kill the cells in the outer layer of the human placenta (the trophoblast membrane), which in turn can kill the placenta. A mere 1/500th the amount needed to kill weeds was able to kill these cells! The amount is so small, according to the study’s authors, that the “residual levels to be expected, especially in food and feed derived from Roundup formulation-treated crops” could be enough to “cause cell damage and even [cell] death.”

Thank you

Might help overpopulation?!

Scary how Monsanto is poisoning our world

Finding anything that hasn't been tainted by GMO products is extremely difficult since it is present in so many prepackaged foods, fresh vegetables, etc.. Monsanto has flooded our food supply in such a gross manner, it's literally hard for those on a strict budget or not to try and get away from. Most cereals, breads, condiments, gum, many chocolate products (Hershey's, Dove, Cadbury, etc.), any restaurant that is not organic, which is 99.9%, are tainted with Monsanto crud. I know I don't directly eat anything that is GMO because I am allergic to soy, so I read each and every label on anything I buy and know the sources I buy from do everything they can to not have GMO in their product line, but they too have a difficult time because of cross-pollination issues with GMO crops and non-GMO. Labeling is not going to be good enough.

Maria C; let's see if you are laughing when your children or your children's children start developing disease or illness from unknown sources, worse yet; congenital birth defects that could have been prevented simply by eating non modified healthy food. That danger exists for us all, and we're not laughing!

Thanks for the article. I followed the links to the source of the research. It seemed to say that the difference between GM and organic performance of soy was minimal.

Maybe it's a part of population control by the 1%.

we should be working to increase fertility and natural life not modify it

3:56AM PDT on Mar 20, 2012

these foods should be banned

This has become a world wide problem. Here in South Africa legislation exists (albeit to a limited extent), requiring labeling of foods, which sadly is not being adequately applied or enforced. Huge proportions of maize and other foodstuffs are found in products produced by large milling companies like Bokomo and sold by supermarket chains, without adequate label disclosure. Most of this instigated by the likes of Montsanto GE modified seed and weed control poisons, which are infecting the countries food sources. People need to get this message urgently and the rollout plans in place for educating the citizens of California are eminently laudable. More strength to all those who are responsible for its organization and to all those with the moral conviction to support them.
Your voices are essential.
