To investigate the differences in baseline characteristics and treatment outcomes between hirsutism and non-hirsutism polycystic ovary syndrome patients，and to provide a theoretical basis for the syndrome characteristics and diagnosis and treatment of polycystic ovary syndrome.Methods:This study was a secondary analysis based on a multicenter，randomized，double-blind，placebo-controlled infertility clinical trial.According to the Rotterdam diagnostic criteria，644 women with infertility polycystic ovary syndrome were included in 19 sub-centers between November 2009 and February 2013.Subjects were divided into hirsutism group (HI group，≥5 points) and non-hirsutism group (Non-HI group,<5 points) according to the Ferriman-Gallwey scoring criteria.The differences in baseline characteristics and clinical outcomes between the two groups were compared.Results:1.Baseline characteristics：waist circumference，diastolic blood pressure，heart rate，LH and LH/FSH levels were significantly lower in the HI group than in the Non-HI group (P<0.05)，while the proportion of the acne score and the bilateral ovary “necropic sign” was higher than Non-HI group (P<0.05); 2.Clinical outcomes：The pregnancy rate of subjects in HI group was significantly lower than that in Non-HI group (P=0.04).Conclusion:The hirsutism and non-hirsutism polycystic ovary syndrome subjects have different clinical phenotypic characteristics.The hirsutism polycystic ovary syndrome subjects have the characteristics of low conception rate.
