Abstract

Humans are ubiquitously exposed bisphenol A (BPA), and epidemiological studies show a positive association between BPA exposure and diabetes risk, but the impact of parental exposure on offspring diabetes risk in humans is unknown. Our previous studies in mice show disruption of metabolic health upon maternal BPA exposure. The current study was undertaken to determine whether exposure in fathers causes adverse metabolic consequences in offspring. Male C57BL/6 J mice were exposed to BPA in the diet beginning at 5 weeks of age resulting in the following dietary exposure groups: Control (0 μg/kg/day), Lower BPA (10 μg/kg/day) and Upper BPA (10 mg/kg/day). After 12 weeks of dietary exposure, males were mated to control females. Mothers and offspring were maintained on the control diet. Post-pubertal paternal BPA exposure did not affect offspring body weight, body composition or glucose tolerance. However, when fathers were exposed to BPA during gestation and lactation, their female offspring displayed impaired glucose tolerance in the absence of compromised in vivo insulin sensitivity or reduced ex vivo glucose-stimulated insulin secretion. Male offspring exhibited normal glucose tolerance. Taken together, these studies show there is an early window of susceptibility in which paternal BPA exposure can cause sex-specific impairments in glucose homeostasis.
