Objective:To observe the expression of endometrial homologous box gene A10(HOXA10),Integrinαvβ3 and leukemia suppressor factor(LIF)in peri-implantation mice,and to investigate the effect of controlled superovulation(COH)on endometrial receptivity in mice.Methods:After COH model preparation and blastocyst transplantation,kunming pure-bred mature mice were randomly divided into natural blastocyst+natural pseudocyst group,COH blastocyst+natural pseudocyst group,natural blastocyst+COH pseudocyst group,and COH blastocyst+COH pseudocyst group.The pregnancy rate and average number of beds in each group were observed on day 6 of conception.Western blot and RT-PCR were used to detect the expression of HOXA10,Integrinααvβ3,LIF protein and mRNA in the endometria of mice on day 5 of conception.Results:The pregnancy rate and average number of beds in the COH group were lower than those in the natural receptor group.The expression of HOXA10,Integrinααvβ3 and LIF in endometrium was significantly lower than that of the natural receptor mice(P<0.01).Conclusion:Superovulation drugs down-regulate the expression of HOXA10,Integrinαvβ3 and LIF in endometrium during the implantation window,reduce endometrial receptivity,and lead to low clinical pregnancy rate. 展开更多
