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.
