The changes of estrogen receptor and pogesterone receptor in the endometria of proliferative phase in polycystic ovary syndrome patients / 中国医师杂志

ABSTRACT

Objective To explore the changes of estrogen receptor (ER) and progesterone receptor (PR) in the endometria of pro-liferative phase in polycystic ovary syndrome (PCOS) patients. Methods Thirty-two patients who suffered PCOS combined with infertilitas feminis were enrolled in this study, and 20 cases of tubal infertilitas feminis having the corresponding time period were selected as controls. The expressions of estrogen receptor (ER) and progesterone receptor (PR) in the endometria were observed by pathological examination and immunohistochemical staining. Results The expressions of ER and PR in the PCOS group in the glands and interstitium of endometrial a-mong three different periods were not significantly different. The expressions of ER and PR in the glands and interstitium of endometrial a-mong three different periods in the control group were significantly different. There was no statistical difference in the expressions of ER, PR in the glands and interstitium of the early endometria between PCOS group and control group. The expressions of ER in the glands and inter-stitium of the middle endometrial in PCOS group was significantly lower than that of control group. The expressions of ER and PR in the glands and interstitium of the late proliferative endometrial in PCOS group was significantly lower than that of control group. Conclusion ER and PR of endometrial in the PCOS patients decreased. The cyclical of ER and PR in the PCOS patient were irregular.
