Objective To explore the effect of chronic unpredictable mild stress (CUMS) on the reproductive function of mice and provide a suitable animal model for reproduction and stress. Methods A total of 240 female Kunming mice were feed for 5 days, and then divided randomly into the control group (n=90) and experimental group (n=150). The mice in the experimental group were stressed by 9 chronic mild unpredictable stress factors for 4 weeks and validated by open field test and sucrose consumption test. We administrated pregnant mare serum gonadotropin (PMSG)/human chorionic gonadotropin (HCG) for induction of superovulation and observed the ovarian response and embryo development potential. Results After 4-week CUMS stimulation, the weight gain, 2% sugar consumption test and open field test were significantly different between the mice in two groups (P>0.05). After PMSG/HCG was administrated, the antra follicles and preovulatory follicles significantly reduced significantly in the experiment group than that in the control group (P<0.05); the number of oocytes, fertilization rate, 2-cell embryos, D4 embryos, blastocysts, high quality embryo rate and D5 bed points were all significantly decreased in the experiment group than those in the control group (P<0.05). Conclusion The CUMS female Kunming mice model is a kind of emotional stress animal model with low reproductive function, which is effective, operable and repeatable; it could be used for further study on the mechanism of reproductive medicine.
