The global in-vitro fertilization market is expected to reach an astonishing $21.6 billion by the year 2020, which of course raises the question: why are so many people becoming infertile in the first place, anyway?
People in the organic and GMO-free movement have long suspected that the food system and its overreliance on unnatural and chemical-laden techniques could be at least partially responsible for quite a while, and now new research has suggested that they may be on to something after all.
Organic Food Could Help Solve the Fertility Crisis: Study
According to this article from the website Huffington Post, the Journals of the American Medical Association have published research in recent weeks showing large increases in pesticide exposure to human beings, and also suggesting that pesticide-laden foods and fertility issues could be connected after following over 300 women at a fertility clinic and tracking their progress.
As noted in the article, women who regularly ate fruits and vegetables treated with chemical pesticides had lower success rates in getting pregnant through IVF, while those who ate organic food had a reduced risk of pregnancy loss and increased fertility rates.
In the study of 325 participants (of an average age of 35.1), women in the highest quartile of measured intake of high-pesticide residue fruits and vegetables had an 18% lower probability of clinical pregnancy and a 26% lower probability of live birth.
That means switching away from eating non-organic vegetables with high pesticide residues (such as apples, spinach, strawberries and others; see top 5 list here) may be able to quickly boost your fertility at significant levels.
“I was always skeptical that pesticide residues in foods would have any impact on health whatsoever. I thought we were not going to find anything,” said lead researcher Jorge Chavarro, MD, to Time Magazine, adding that he is now more likely to buy organic apples than before.
Most U.S. “conventional” apples are treated with a chemical called diphenylamine, which is banned in Europe and used to prevent “storage scald” from happening. This is just one result of a system in which the pesticide industry is allowed free rein in the United States and has been allowed to shape policies in its favor of its chemicals, according to those in the non-GMO and organic movement.
Epidemiologist and pediatrician Phillip Landrigan, MD of Mount Sinai, called the Harvard study a “warning that our current lassez-faire attitude toward the regulation of pesticides is failing us” in the same issue of JAMA.
With much evidence showing that human fertility is on the decline and more and more couples lining up for some sort of intervention to fix the issue, Landrigan called for a re-examination of how doctors educate patients on diet.
“Encourage our patients to eat organic,” Dr. Landrigan wrote as a recommendation, saying that reduced sperm counts and birth defects are almost certainly related to the overabundance of chemicals on food and in the environment.
“And educate elected officials and other policy makers about the hazards of pesticides—make them realize that pesticides are not merely a regulatory issue or an environmental problem, but that in fact these potent chemicals can have powerful effects on human health that need to be intelligently confronted.”
Pesticide Levels Rising in Human Bodies
Also noted in the article was another study published in JAMA documenting large increases in the amount of glyphosate humans are being exposed to, leading to more calls for government officials to step in and make long-awaited changes.
Glyphosate, the main ingredient in Monsanto’s best-selling Roundup weedkiller, was declared a probable human carcinogen by the World Health Organization’s International Agency for Research on Cancer in spring 2015, which Monsanto has disputed by pointing to approvals from government health agencies. Still, research on glyphosate’s toxicity continues to mount, especially in light of recent scandals showing that Monsanto worked with academics in order to skew research.
According to the other study, undertaken by UC San Diego researchers, human exposure to glyphosate has increased about 500% since the introduction of genetically engineered crops (also known as GMOs or genetically modified organisms), most of which are created in a laboratory to withstand large-scale sprayings of Roundup.
The number found according to the JAMA study is 100-fold greater than levels of glyphosate fed to rats that developed liver disease in one long-term feeding study.
Going Organic to Preserve Fertility?
These studies are just a small sampling of how pesticides have been linked to countless health maladies, and how caution should be taken for anyone hoping to conceive when it comes to pesticide consumption.
While there are many factors that go into fertility, one thing’s for sure — exposure to too many pesticides is not helping anyone, leading Dr. Landrigan to call for better regulations going forward.
“We need to overcome the strident objections of the pesticide manufacturing industry, recognize the hidden costs of deregulation, and strengthen requirements for both premarket testing of new pesticides, as well as postmarketing surveillance of exposed populations — exactly as we do for another class of potent, biologically active molecules—drugs.”
