BPA exposure may lead to pregnancy difficulties

Mouse-science-diabetes Discovery 12.2.10

A study published this month in Environmental Health Perspectives focuses on the affect endocrine-disrupting chemical(and popular water bottle/receipt additive) Bisphenol-A has on the reproductive abilities of mammals over the course of their lifetime. While the study focused on mice, researchers believe the results may lead to further concern for humans in contact with the ubiquitous substance.

The study involved allowing a selection of female mice to become pregnant. At that point, the pregnant mice were separated and given BPA-containing solutions. The concentration of BPA in these solutions ranged from miniscule amounts to a mouse-sized version of the human dose. A control group was given none.

These different groups of mice were then allowed to continue breeding throughout their lifespan to see how the amount of BPA would affect their ability to breed.

Within four months, litters of those given the BPA solution had shrank by 25%, and the frequency of pregnancies was also notably lower.
