BPA shown to disrupt thyroid function in pregnant animals and offspring
Date:11/13/2012

Chevy Chase, MD In utero exposure to bisphenol A (BPA) can be associated with decreased thyroid function in newborn sheep, according to a recent study accepted for publication in Endocrinology, a journal of The Endocrine Society. Hypothyroidism is characterized by poor mental and physical performance in human adults and in children can result in cognitive impairment and failure to grow normally.

BPA, a major molecule used in the plastic industry, has been shown to be an endocrine disruptor that could exert deleterious effects on human health. Most investigations have focused on reproductive functions, but there is evidence that BPA might have negative effects on other endocrine systems including thyroid function. The current study used sheep, a relevant model for human pregnancy and thyroid regulation and ontogeny, and analyzed the internal exposures of the fetuses and their mothers to BPA and determined to what extent those exposures may be associated with thyroid disruption.

"Our study is the first to show that BPA can alter thyroid function of pregnant animals and their offspring in a long-gestation species with similar regulation of thyroid function as humans," said Catherine Vigui, PhD, of Toxalim, Research Centre in Food Toxicology in Toulouse, France and lead author of the study. "Because of the potential consequences of maternal/fetal thyroid disruption on neural and cognitive development, we think that our study warrants the need for further investigations on the effect of BPA on thyroid function."

This study was conducted on adult ewes that had multiple pregnancies before being included in the experiment. Some of the pregnant ewes received daily subcutaneous injections of BPA while the remainder were allocated to the control group. Blood samples were taken from jugular blood, amniotic fluid, placenta samples and cord blood to determine levels of BPA, thyroid-stimulating hormone (TSH) and thyroxine. Results showed th
