Effects of endometriosis on the reproductive ability of mice / 中国实验动物学报

ABSTRACT

Objectives The aim of the study was to establish a mouse model of endometriosis , and to observe the effects of endometriosis on the reproductive ability in the mice .Methods The mouse models of endometriosis was estab-lished by subcutaneous and intraperitoneal injection of heterogenous endometrium .The pregnancy rate and live embryo number in the experimental , sham operation and blank groups were observed and compared , and the effects of endometrio-sis on reproductive ability of the mice were evaluated .Results Two weeks after the establishment of the mouse model of endometriosis , there were lesions in the peritoneal cavity and subcutaneous tissue of the mice .Compared the pregnancy rates among the model group , sham operation group and blank group , the differences were statistically significant ( P<0.05).Compared the live embryo number in the three groups , there were also significant differences (P<0.05).Con-clusions A mouse model of endometriosis is successfully established , and it demonstrates that endometriosis may affect the reproductive ability of mice .
