(Medical Xpress) -- A University at Albany-led research team has identified a link between exposure to bisphenol A (BPA), a molecular component of plastics and resins used in baby bottles and the linings of canned foods, and a reduction in the peak estrogen concentrations among women undergoing in-vitro fertilization (IVF).  The reduced estrogen concentrations could adversely influence the quality of egg-containing follicles. http://medicalxpress.com/news/2011-08-bisphenol-exposure-impacts-in-vitro-fertilization.html Health Tue, 09 Aug 2011 11:00:02 EST news232103428 A link between chemicals called phthalates and thyroid hormone levels was confirmed by the University of Michigan in the first large-scale and nationally representative study of phthalates and BPA in relation to thyroid function in humans. http://medicalxpress.com/news/2011-07-large-human-links-phthalates-bpa.html Health Mon, 11 Jul 2011 13:27:55 EST news229609657 Several chemicals that can accumulate to high levels in our body (for example BPA and some pesticides) have been recently linked to an increased risk of cancer and/or impaired responsiveness to anticancer drugs. A team of researchers, led by Sridhar Mani, at Albert Einstein College of Medicine, New York, has now identified a potential mechanistic link between environmental exposure to these foreign chemicals (xenogens) and cancer drug therapy response and survival. http://medicalxpress.com/news/2011-07-pxr-stone-environmental-chemical-cancer.html Cancer Mon, 11 Jul 2011 12:53:42 EST news229607612 While the U.S. Food and Drug Administration notes "some concern" with the controversial chemical BPA, and many other countries, such as Japan and Canada, have considered BPA product bans, disagreement exists amongst scientists in this field on the effects of BPA in animals and humans. The latest research from the University of Missouri shows that BPA causes male deer mice to become demasculinized and behave more like females in their spatial navigational abilities, leading scientists to conclude that exposure to BPA during human development could be damaging to behavioral and cognitive traits that are unique to each sex and important in reproduction. http://medicalxpress.com/news/2011-06-bpa-exposed-male-deer-mice-demasculinized.html Health Mon, 27 Jun 2011 15:00:13 EST news228393088 Despite years of scientific studies, reports, lawsuits, congressional inquiries, claims and counterclaims, the question of whether bisphenol A (BPA) poses health threats to people lacks a definitive answer, according to a package of articles on the controversial substance in the current edition of Chemical & Engineering News (C&EN), ACS's weekly newsmagazine. http://medicalxpress.com/news/2011-06-bisphenol-restrict.html Health Wed, 08 Jun 2011 10:04:13 EST news226746236 Exposure in the womb to bisphenol A (BPA), a chemical widely used in the food and medical industries, causes changes in female primates' uterus development, new research suggests.

In the study, researchers compared BPA concentrations in mice that were given a steady diet supplemented with BPA throughout the day, compared to the more common lab method of single exposure, and found an increased absorption and accumulation of BPA in the blood of mice. http://medicalxpress.com/news/2011-06-exposure-bpa-underestimated.html Health Mon, 06 Jun 2011 03:24:02 EST news226549419 A new case study examining an infant's neurobehavioral abnormalities and extremely high bisphenol A (BPA) concentration of the baby's mother suggests a link between the two.
