Prenatal mild stress disrupts corticosterone levels in offspring. (A) Body weight gain of male rats prenatally exposed to stress (PS, n = 28) and control group (CTR, n = 8), showing no differences in body weight gain as animals aged. (B) Body weight gain of female rats prenatally exposed to stress (PS, n = 20) and control group (CTR, n = 9), showing no differences between groups. (C) Basal serum corticosterone levels of male and female PS is increased in comparison with CTR rats, although not statistically significant (n_{PS males} = 6, n_{CTR males} = 6, n_{PS females} = 6, n_{CTR females} = 4). (D) Upon acute stress exposure (restraint for 30 min), male and female PS rats presented significantly increased serum levels of corticosterone (n_{PS males} = 8, n_{CTR males} = 4, n_{PS females} = 6, n_{CTR females} = 6).
