Pup retrieval by sires. Average latency time in seconds to start retrieval of biological pups by wild‐type (WT) or CD38^−/− sires at 30 min (A) and 24 h (B) after single subcutaneous injection of PBS, OT, or LOTs (30 ng/mouse), n = 5–6 for each test. One‐way ANOVA followed by Bonferroni post hoc test was performed for 30 min (F _5,39 = 7.60, P = 0.0001) and for 24 h (F _5,40 = 5.35 P = 0.0007). *P < 0.05, Bonferroni's post hoc test compared with CD38^−/− treated by PBS. OT, Oxytocin; PBS, phosphate‐buffered saline.
