Bisphenol A affects sex-specific reproductive behaviors in a monogamous animal species
Date:2/11/2013

"We use animal models to provide informative decisions about our own health and the risks associated with BPA," Rosenfeld said. "What we have observed in those models is that BPA affects male rodents differently than females. Risk assessment studies examining the impacts of BPA in humans could be more accurate if they took sex into account when monitoring for changes in children's behavioral patterns."

Rosenfeld's most recent study observed the influence of prenatal BPA exposure on California mice, whereas earlier studies had used deer mice. The two rodent species have contrasting mating behaviors. California mice are monogamous, as opposed to the polygamous deer mice. Although BPA affected the California mice differently than the deer mice, both rodent species' behaviors were altered in ways that would decrease their ability to successfully mate and pass on their genes to future generations. Since two species of rodents with different mating patterns were both affected, it suggests that BPA disrupts essential reproductive-associated behaviors that are species- and sex-specific.
