Effects of perinatal oxytocin (OXT) or prenatal OXT receptor antagonist treatment on offspring behaviors. (a) Number of USV calls at PD 8 (in all seven groups, n = 40: male = 20, female = 20; ND vs. C/S, p = 0.016; ND vs. born to L-368,899-treated dams via natural delivery [LND], p = 0.009). (b) Approaching time of male mice to the stranger cage (S) and the empty cage (C) in the 3-CSI test (ND: p = 0.001, ND-OXT: p < 0.001, preOXT-C/S: p < 0.001, p = 0.268, C/S-OXT: p < 0.001, LND: p = 0.804, LND-OXT: p < 0.001). (c) Number of marbles buried by male mice in the marble burying (MB) test (ND vs. C/S: p < 0.001, ND vs. LND: p = 0.035). Data represent the mean ± SEM. The numbers in parentheses indicate the numbers of mice tested and their litters (mice/litters) in each group. *p < 0.05, ***p < 0.001.
