[Preliminary study on the value of ratio of serum luteinizing hormone/follicle-stimulating hormone in diagnosis of polycystic ovarian syndrome among women with polycystic ovary].

Objective: To investigate the value of ratio of luteinizing hormone (LH) to follicle-stimulating hormone (FSH) in diagnosis of polycystic ovarian syndrome (PCOS) among women with polycystic ovary (PCO) and to compare the difference of the diagnostic criteria between the Rotterdam Consensus and the Committee for Reproductive and Endocrine in Japan Society of Obstetrics and Gynecology.

Methods: By means of transvaginal Doppler ultrasound, 195 women with PCO were diagnosed in Nanfang Hospital of Reproductive Medicine Center and compare difference of multiple clinical indexes according to Rotterdam consensus and Japan consensus respectively. In the mean time, the ratio of LH/FSH, the level of LH, testosterone (T) and recevier operating characteristic (ROC) curve were explored to on the value of diagnosis of PCOS.
