“The routine use of common pesticides in agriculture is no longer an ethically viable option for sustainable food production,” according to a new review in Reproduction & Fertility by livestock researcher Whitney Payne, Ph.D. candidate, and Kelsey R. Pool, PhD, of the School of Agriculture and Environment at The University of Western Australia. They base their position on the endocrine-disrupting qualities of many pesticides.The authors describe endocrine-disrupting compounds (EDCs) as “an inescapable feature of modern life” and note that the “farming systems sit at the intersection of...

(Beyond Pesticides, June 23, 2026) With new medications (including those containing GLP-1-receptor-agonist or glucagon-like peptide-1) exploding onto the market to treat obesity and serious related health threats, it is easy to lose sight of critical policy issues that allow the ongoing introduction of obesogenic pesticides and other chemicals (endocrine disrupting chemicals that affect metabolism and fat storage) into the food supply. The science on obesity has found that the most common form is attributable to a combination of genetic and environmental factors. Because there are many...

(Beyond Pesticides, July 8, 2026) This piece reports on yet additional new studies linking pesticides to breast cancer. A number of recent reviews make it clear that pesticide exposure per se raises the risk of breast cancer, across a wide swath of pesticide types. One would think that with the body of science linking breast cancer with pesticide exposure, covered extensively by Daily News and the Pesticide-Induced Diseases Database, a scientific-based regulatory system would respond with a sense of urgency. And yet, that is not the case, as the U.S. Environmental Protection Agency (EPA)...

A multitude of studies link exposure to glyphosate and glyphosate-based herbicides to harmful impacts on women's reproductive health.

(Beyond Pesticides, August 27, 2026) Pesticides contribute to an array of gynecological cancers (ovarian, endometrial, cervical, uterine, vaginal and vulvular, of which the first three are most common). A review by Iranian researchers examines studies of pesticide links to these diseases published between January 2000 and February 2025. The literature review encompasses human cohort, prospective and retrospective longitudinal, and cross-sectional methods, along with other results showing mechanistic evidence from experimental animal or in vitro studies. Thirty studies made the final cut....

The Copenhagen Analgesic Study holds the potential to provide novel and comprehensive insights into the impact of early and late prenatal exposure to mild analgesics and other endocrine-disrupting chemicals on future reproductive function in the offspring.

Occupational, residential, and dietary exposure to pesticides are linked to thyroid dysfunction and cancer.

In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heterocl...

Tell EPA and Congress that pesticide use cannot continue without findings of no endocrine disruption. Demand that EPA test for and act on endocrine disruptors as required by law. #pesticides #menshealth #spermcount #fertility #globalissues #endocrine #organics #takeaction

Tell EPA that pesticide use cannot continue without findings of no endocrine disruption. Tell Congress to ensure that EPA does its job.

(Beyond Pesticides, February 15, 2022) A synthetic weed killer linked to cancer, endocrine (hormone) disruption, reproductive harm and birth defects can be found in the bodies of 1 in 3 Americans, according to research published in Environmental Health by scientists at George Washington University. The chemical in question is not glyphosate (though current data indicate similar results are likely) but 2,4-D, an herbicide that is increasingly used when weeds growing near genetically engineered  (GE) crops have developed resistance to the repeated use of Roundup and other glyphosate-based weed killers. “Our study suggests human exposures to 2,4-D have gone up significantly and they are predicted to rise even more in the future,” Marlaina Freisthler, a PhD student and researcher at the George Washington University, said. “These findings raise concerns with regard to whether this heavily used weed-killer might cause health problems, especially for young children who are very sensitive to chemical exposures.” Researchers conducted their analysis based on data from the National Health and Nutrition Examination Survey, which includes urinary concentrations of 2,4-D from 14,395 participants spanning 2001 to 2014. Between those years, the use of 2,4-D increased rapidly from its relative low point at the beginning of the century. “Roundup […]

(Beyond Pesticides, January 26, 2018) Triclosan may be on its way out in soaps and disinfectants, but its presence on toothbrushes could stick around for a long time, according to research published in Environmental Science and Technology by a group of scientists from University of Massachusetts, Amherst (UMass Amherst). The Food and Drug Administration (FDA) banned the use of over the counter triclosan-containing soap in 2016, and late last year extended the ban to include health care and hospital settings, but the toxic antibacterial can still be found in toothpaste and other consumer products. Many may have have checked their toothpaste label and switched to a non-triclosan toothpaste after the recent news, but scientists say that exposure to this persistent chemical may continue through toothbrushes, if triclosan toothpaste was previously used. To test triclosan absorption while brushing, researchers purchased 22 different toothbrushes, each with different components, from bristles only, to those with polishing cups, gum protectors, or tongue cleaners. Different toothpastes, including six with and 15 without triclosan, were also used.  A mixture used to imitate saliva was added to toothpaste and put into a vial that was then brushed with different toothbrushes over a 3 month period – the […]

(Beyond Pesticides, April 4, 2017) Exposure to commonly used pyrethroid insecticides results in the early onset of puberty in boys, according to a study presented at the 99th meeting of the Endocrine Society in Orlando, Florida this week. Pyrethroids, which exhibit endocrine disrupting properties, have the ability to interfere with the proper regulation of the human body’s hormonal system. This research is the first to investigate not only the association between pyrethroids and accelerated puberty, but also the causal mechanisms involved in the physiological changes taking place within the human body. For the study, Jing Liu, PhD, and colleagues from Zhejuang University in China, analyzed the urine in 463 Chinese boys aged 9 to 16 for the presence of metabolites from the pyrethroid insecticide cypermethrin. Results show that a 10% increase in the metabolite 3-PBA is associated with a roughly 4% increase in luteinizing and follicle-stimulating hormones, which facilitate puberty and sperm production. The author’s note that, “Boys with increased urinary levels of 3-PBA have a significantly increased risk of earlier pubertal onset, in which the odds of being in an advanced pubertal stage are increase by 73% to 110%.” The study, acknowledging the limitation in determining causality, further investigates the […]
