The Role of LH and FSH in Polycystic Ovary Syndrome

多囊卵巢综合征(PCOS)是一种由于糖代谢异常与内分泌失调引发的以高雄激素血症、稀发排卵或无排卵、胰岛素抵抗、超重或肥胖、月经不规则等为特征的一种生殖内分泌性疾病，是困扰育龄期女性难孕难育、不孕不育的重要原因之一。在PCOS中，下丘脑–垂体–卵巢轴功能障碍是造成多种不同临床表现及卵巢功能和结构改变的主要原因。卵泡刺激素和黄体生成素是重要的垂体促性腺激素。在PCOS疾病的发生和发展过程中，黄体生成素增多、卵泡刺激素降低、黄体生成素/卵泡刺激素比值升高，对于该病的诊断有重要的提示意义，同时对于PCOS治疗后的临床预后有着一定的预测意义。Polycystic ovary syndrome (PCOS) is a reproductive endocrine disease caused by abnormal glucose metabolism and endocrine disorders, which is characterized by hyperandrogenism, rare ovulation or anovulation, insulin resistance, overweight or obesity, irregular menstruation, etc. It is one of the important reasons that plague women of childbearing age who are difficult to conceive, have children and have infertility. In PCOS, dysfunction of the hypothalamic-pituitary-ovarian axis is the main cause of various clinical manifestations and changes in ovarian function and structure. Follicle stimulating hormone and luteinizing hormone are important pituitary gonadotropins. During the occurrence and development of PCOS, the increase of luteinizing hormone, the decrease of FSH, and the increase of the ratio of luteinizing hormone to FSH pose important suggestive significance for the diagnosis of PCOS, and also represent certain predictive significance for the clinical prognosis after treatment of PCOS.
