Reproductive Health

Glyphosate-based Herbicide Impairs Female Fertility - new study (GM Watch. 24 July 2018.)  What the 3 month studies mandated by regulatory agencies cannot show:  The dosages were selected based of the reference dose (dose supposed to be safe over a lifetime) and the higher dose was 1/5th of the "industry-declared no-observed adverse effect level (NOAEL)". 'However, although all glyphosate herbicide-exposed first generation female rats became pregnant, they had a lower number of implantation sites of fertilized eggs, compared with controlsThe second generation offspring from both glyphosate herbicide-exposed groups showed delayed growth, evidenced by lower foetal weight and length, and a higher incidence of abnormally small foetuses...Also, to the authors' surprise, malformations (conjoined foetuses and abnormally developed limbs) were detected in the second generation of offspring from the higher dose of glyphosate herbicide group...The findings of malformations reflect epidemiological findings that people living in an Argentine town in the heart of the GM soy and maize growing area, where glyphosate-based herbicides are sprayed in large amounts, suffer birth defects at twice the national average rate.'

DDT Resistant Fruit Flies Show Reproductive Difficulties  (Beyond Pesticides, June 7, 2017) Fruit flies that developed a genetic resistance to the insecticide DDT have lower success at mating than those without similar changes, according to a study published last month in the journal Behavior Genetics. The results were surprising to researchers, given that the resistance developed through changes to a single allele (a variation of a single gene). “It is amazing that even if all the genes are exactly the same, having this one gene expressed at a higher level has all these effects,” said Professor Nina Wedell, PhD, of the Centre for Ecology and Conservation on Exeter’s Penryn Campus in Cornwall, UK to Phys.org. The study raises possible concerns about the effect of pesticide exposure to non-target (not the focus of pesticide use) insects that are integral to a healthy ecology and food web...However, it should be noted that the documented effects in this study are only seen in the absence of insecticide exposure.  SNAP Comment: These types of effects are not mandated studies prior to pesticide registration. I also think the study raises possible concerns about genetic engineering (GE). If the change in one naturally occurring allele can cause problems, what can the insertion of a new gene do?... (also filed under  wildlife/insects and gmos/Safety/Health Effects)

California to List Atrazine and Other Triazine Weedkillers to Prop 65 as Reproductive Toxicants  (Beyond Pesticides, July 13, 2016)  'The listing of these chemicals was initially to be effective on August 3, 2015. However, Syngenta, manufacturer of atrazine, challenged the listing decision, leading to a delay in the formal decision. Syngenta Crop Protection v OEHHA (Sacramento Superior Court case#34-2014-800001868). Syngenta’s challenge was unsuccessful and now the official listing can move forward, in spite of Syngenta’s pending appeal.'..'Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The proposition protects the state’s drinking water sources from being contaminated with chemicals known to cause cancer, birth defects or other reproductive harm, and requires businesses to inform Californians about exposures to such chemicals.'

Endocrine Disruptors Lead to Female Reproductive Disorders Costing Billions (Beyond Pesticides, April 26, 2016) A study published last month finds that exposure to endocrine-disrupting chemicals (EDC) plays an important role in the development of certain female reproductive disorders, and ultimately results in significant economic costs to society. Scientists analyzed the economic impact of a number of EDCs, including phthalates, bisphenol A (BPA), polychlorinated biphenyls (PCBs), dioxins, perfluoroalkyl compounds, as well as DDE and organophosphate and organochlorine pesticides.

Sperm Quality

Pesticide Residues on Foods Shown to Affect Sperm Quality (Beyond Pesticides, April 1, 2015) The study, published online in the journal, Human Reproduction, adds to a growing body of research that finds pesticide exposures give rise to impaired reproductive function, including reduced sperm counts, sperm quality and reduced fertility in exposed men. The results of this study also underscore the importance of an organic diet in reducing pesticide exposures.The study is believed to be the first to look into the consumption of fruits and vegetables with high levels of pesticide residue in relation to semen quality, PAULE'S NOTE: as our ability to measure minute amounts of chemicals increases, we are finding relationshisps that eluded us earlier, when testing was not good enough to detect common amounts of pesticide we are exposed to on a daily basis.

Pesticide Exposure Linked to Abnormal Sperm Development (Beyond Pesticides, November 10, 2015) The study was condicted in the faro Isands where contaminated whales are an important part of the diet. 

Pesticides in Fruits and Vegetables Linked to Poor Sperm Quality
(Organic consumer Association, March 2015)The researchers found that men who ate the highest levels of pesticide residue had a 49 percent lower sperm count and a 32 percent lower percentage of normally-formed sperm than men who consumed minimal amounts of pesticide residues.
