PFOA and PFOS cause lower sperm counts and smaller penises, study finds
“Experiments they conducted in the laboratory show that PFOA and PFOS can bind with testosterone receptors inside the cell and disrupt the normal function of the hormone.”
Administering hormones affects DNA
“researchers have demonstrated for the first time that the administration of even extremely low doses of an endocrine disruptor – in this case, an endogenous oestrogen – leads to epigenetic changes in a pregnant sow’s DNA.”
Endocrine-disrupting pesticides impair frog reproduction
“The scientists found that linuron, which is used as a pesticicide, impaired the males’ fertility, and that tadpoles developed ovaries instead of testicles to a greater extent, which caused a female-biased sex ratio.”
Everyday chemicals may affect brain development, including foetal IQ
“Our paper, published on March 7 in Scientific Reports, shows that young tadpoles exposed to a mixture of common chemicals at concentrations routinely found in human amniotic fluid not only modified thyroid hormone signalling but also reduced the total number and size of neurons and inhibited tadpole movement.”
Chemicals in lavender and tea tree oil appear to be hormone disruptors
“A new study lends further evidence to a suspected link between abnormal breast growth in young boys—called prepubertal gynecomastia—and regular exposure to lavender or tea tree oil, by finding that key chemicals in these common plant-derived oils act as endocrine-disrupting chemicals.”
Painkiller may disrupt sex hormones, placing unborn babies at risk
“In this study, researchers found an association with use of the drug and lower levels of “sulfated” forms of sex hormones in men and women. Also called neurosteroids, many of these hormones are active in the brain. One of these hormones, DHEA-S, is well known to be important for placental health.”
How food preservatives may disrupt human hormones
“We discovered that each of these chemicals damaged hormones that communicate between the gut and the brain,” said Dhruv Sareen, PhD, assistant professor of Biomedical Sciences and director of the Induced Pluripotent Stem Cell Core Facility at the Cedars-Sinai Board of Governors Regenerative Medicine Institute. “When we tested the three together, the combined stress was […]
Exposure to common flame retardants may raise the risk of papillary thyroid cancer
“Some flame retardants used in many home products appear to be associated with the most common type of thyroid cancer, papillary thyroid cancer (PTC), according to a new study”
Pyrethroid pesticide exposure appears to speed puberty in boys
“Environmental exposure to common pesticides may cause boys to reach sexual maturity earlier, researchers have found.”
Exposure to BPA substitute, BPS, multiplies breast cancer cells
“Bisphenol S (BPS) shows the potential for increasing the aggressiveness of breast cancer through its behavior as an endocrine-disrupting chemical, a new study finds.”
