[摘要] 目的 觀察多囊卵巢綜合征患者子宮內膜雄激素受體表達的改變。 方法 采用免疫組化法對40例多囊卵巢綜合征患者和40例對照子宮內膜雄激素受體表達進行檢測。 結果 PCOS患者子宮內膜雄激素受體表達較對照組增多,主要表現在腺上皮(P<0.05﹚。 結論 多囊卵巢綜合征患者子宮內膜雄激素受體表達增多,影響子宮內膜容受性,是導致多囊卵巢綜合征不育患者促排卵治療后低妊娠率的原因之一。

[Abstract] Objective This study was designed to observe the change of immunohistochemical localization of AR in endometria in women with PCOS. Methods Selected 40 patients with PCOS and 40 infertility patients (tubal or male infertility) .Measurement of AR was carried out with immunohistochemistry. Results The patients with PCOS exhibited elevated endometrial AR expression compared to controls,this increase was most apparent in glandular epithelium(P<0.05). Conclusion The high expression of AR in endometrial glandular cells may be correlated with the low clinical pregnancy rate observed in patients with PCOS after ovulation induction.

多囊卵巢綜合征(polycystic ovarian syndrome,PCOS)是育齡女性最常見的內分泌紊亂性疾病。持續性無排卵是其重要特征之一,在無排卵性不育患者中約占60%~70%。使用炔雌醇醋酸環丙孕酮(達英-35)糾正高雄激素血癥后應用克羅米芬(clomiphene citrate,CC)促排卵是目前大多數PCOS不育患者的常用治療方案。但治療的結局往往是排卵率高而妊娠率低。人類的子宮內膜存在 “種植窗口期”,僅在這一短暫的時間內允許胚胎種植[1]。PCOS不育患者治療后的低妊娠率推測與胚胎種植過程子宮內膜容受性存在問題有關。研究表明,PCOS不育患者復雜的內分泌及代謝紊亂可導致子宮內膜發育障礙而造成容受性的缺陷,產生不良的治療結局。本研究采用免疫組化法測定PCOS患者“種植窗口期”子宮內膜雄激素受體(androgen receptor,AR)的表達,旨在探討PCOS患者子宮內膜AR表達的變化與其不育的關系。
