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 .
ABSTRACT
Objectives To evaluate the effect of a Chinese traditional medicine , Huoxue Xiaoyi Fang , on the embryo development after in vitro fertilization ( IVF ) in mouse models of endometriosis .Methods To observe the quantity of oocytes including the average number of superovulation , fertility rate, 2-cell and 4-cell embryo cleavage rates at different stages in vitro fertilization, and morulation rate among the traditional Chinese medicine group (TCM group), endometriosis model group ( EM model group ) and sham-operated group .To explore the influence of endometriosis and the effect of Huoxue Xiaoyi Fang on the quantity of oocytes and embryonic development after IVF in the mouse models of endometriosis.Results All the average number of superovulation , fertility rate, 2-cell and 4-cell embryo cleavage rates in the three groups showed significant differences (PTCM group>model group .There were no significant differences in the morulation rates in the three groups (P>0.05).There were significant differences among the IVF rates of the three groups (PTCM group>model group .There were significant differences in the final morulation rate among the three groups (P<0.05).Conclusions Endometriosis may influence the quality of embryonic development of EM model mice, including reduced average number of superovulation , fertility rate, and embryo cleavage rate .The Chinese traditional medicine Huoxue Xiaoyi Fang can improve the the quantity of embryonic development after IVF .
