Fig. 2.
A: baseline corticosterone was elevated in chronically stressed (STR), pregnant female mice relative to unrestrained (CON) females at both day 5 and day 10 of pregnancy. Baseline corticosterone (CORT) increased from early to midpregnancy (day 5 to day 10) and was elevated in restrained females relative to unrestrained at both time points. Day 5: CON, n = 5; STR, n = 4; day 10: CON, n = 11; STR, n = 12. B: baseline progesterone was lower in chronically stressed, pregnant female mice on day 5 relative to CON females but not on day 10. C: on day 5, baseline corticosterone was inversely correlated with circulating progesterone. Day 5: CON, n = 10; STR, n = 9; day 10: CON, n = 5; STR, n = 6. **P < 0.02; ***P < 0.001, planned comparisons.
