Abstract

Play behavior is affected by alteration of the hormonal environment during development. In fact, congenital adrenal hyperplasia or early administration of diethylstilbestrol are able to modify female play behavior in mammals. In this research, play behavior of female rats was used to explore the effects of perinatal exposure to low, environmentally relevant dose of bisphenol A (BPA), a xenoestrogen widely diffused in the environment. We used 18 females born to mothers exposed to 40 microg/kg/day BPA during pregnancy and lactation, and 18 control females. The subjects were observed in a heterosexual social situation from 35 to 55 days of age. Six main behaviors were identified by principal component analysis (PCA): exploration, defensive behavior to males, play behavior with males, play behavior with females, low-intensity mating behavior, social grooming. Early administration of BPA was responsible for a significant increase of exploration (including social investigation) (p<0.001), as well as a decrease of play with males (p<0.02) and social grooming (p<0.01) at 45 days of age, indicating a general decrease of playful interactions. In general our results suggest that BPA does not induce a clear masculinization of female behavior, but is able however to defeminize some aspects of female behavior. This result is compatible with the estrogenic properties of BPA, and suggests caution in the use of a chemical that, in the range of human exposure, is able to influence the development of the brain during a critical period, resulting in long-term effects on behavior.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
