Spontaneous abortion and changes of estrogen receptors and progesterone receptors in the endometria of patients with polycystic ovary syndrome / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To explore the relationship between the spontaneous abortion and changes of estrogen receptors (ER) and progesterone receptors (PR) in the endometria of patients with polycystic ovary syndrome (PCOS).@*METHODS@#Thirty-two patients who suffered PCOS combined with infertilitas feminis were enrolled in a experimental group,and 20 patients with tubal infertilitas feminis having the corresponding time period as a control group. The expressions of ER and PR in the endometria were observed by pathological examination and immunohistochemical staining.@*RESULTS@#The expressions of ER and PR in the glands and interstitium of endometrial in the PCOS group were significantly lower than those of the tubal infertilitas feminis group (P=0.004,P=0.001). The expressions of ER and PR in the PCOS group in the glands organ and interstitium of endometrial among 3 different periods were not significantly different (P>0.05). The expressions of ER in the glands of endometrium in the spontaneous abortion group were significantly lower than those of the non-spontaneous abortion group (P=0.02), but there was no statistical difference between the two groups in the interstitium of endometria (P>0.05). The expression of PR in the glands interstitium of endometria showed no statistical difference between the spontaneous abortion group and the non-spontaneous abortion group (P>0.05).@*CONCLUSION@#The decrease of ER and PR of endometrial in the PCOS patients, may be a reason for spontaneous abortion, and the cyclical irregularity of ER and PR in the PCOS patients is another cause of spontaneous abortion.
