Effects of ovulation induction on expression of integrins ?_4?_1 in endometrium / 中华妇产科杂志

ABSTRACT

Objective To study the effect of clomiphene citrate (CC) and human menopausal gonadotropin (hMG) on the expression of integrins ? 4? 1 during implantation window in endometrium. Methods Endometrium integrin ? 4? 1 expression was detected by immunohistochemistry method in the mid secretory phase of 48 normal natural cycles. CC+hCG or CC+hMG+hCG cycles in 30 polycystic ovary syndrom (PCOS) patients and 48 normal women. Results The expression of endometrial integrin ? 4? 1 was stronger in the natural cycls than those of ovulation induction cycles with CC+hCG or CC+hMG+hCG. So was the pregnancy cycles as compared with the non pregnant cycles. Conclusion The endometrial receptivity in the min luteal phase and pregnant rate declined during ovulation induction by CC+hCG or CC+hMG+hCG in either normal women or PCOS patients.
