[摘要] 目的 探讨超声联合体重指数(BMI)诊断多囊卵巢综合征(PCOS)患者不孕的临床价值。方法 回顾性分析2015年1月—2018年12月来该院就诊的800例多囊卵巢综合征患者的B超检查结果及BMI，分层分析BMI与多囊卵巢综合征患者的关系及PCOS患者BMI与怀孕关系。结果 多囊卵巢综合征患者中598例为肥胖型，202例为非肥胖型，肥胖型远多于非肥胖型，肥胖型PCOS患者不孕率为64.5%，非肥胖型PCOS患者不孕率为47.0%，显著低于肥胖型PCOS(χ2=46.490，P=0.000)。此外，降低体重能增加怀孕率。B超结果显示肥胖型PCOS患者卵巢体积显著大于非肥胖型，且卵泡数量增多，无优势卵泡。结论 BMI升高增加多囊卵巢综合征不孕率， 超声联合体重指数(BMI)有助于诊断多囊卵巢综合征患者不孕率。

    [Abstract] Objective To investigate the clinical value of ultrasound combined with body mass index (BMI) in the diagnosis of infertility patients with polycystic ovary syndrome (PCOS). Methods We retrospectively analyzed ultrasound and BMI of 800 patients with polycystic ovary syndrome in the hospital from January 2015 to February 2018. The relationship between BMI and patients with polycystic ovary syndrome and the relationship between BMI and pregnancy in PCOS patients were analyzed. Results 598 of patients with polycystic ovary syndrome were obese ......
