title: Endocrine and metabolic characteristics of polycystic ovary syndrome in Chinese women with different phenotypes.
abstract: OBJECTIVE
  The aim of this study was to describe the endocrine and metabolic characteristics of Chinese women with polycystic ovarian syndrome (PCOS) according to different phenotypes, including menstrual cycle pattern and body mass index (BMI).
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  A total of 3539 patients with PCOS and 590 controls were recruited from the Centre for Reproductive Medicine. Patients with PCOS were divided into three groups according to the characteristics of the menstrual cycle (amenorrhoea, oligomenorrhea and eumenorrhea) and the BMI (<25 kg/m(2) ; 25 ≤ and ≤ 30 kg/m(2) ; and BMI > 30 kg/m(2) ).
  
  
  METHODS
  Waist circumference, hip circumference, weight, height, Ferriman-Gallwey score, and endocrine and metabolic variables were measured.
  
  
  RESULTS
  The serum testosterone, luteinizing hormone (LH) and oral glucose tolerance test 2 h-glucose levels were increased in the amenorrhoea group (P < 0·05). The triglycerides (TG) and low-density lipoprotein-cholesterol (LDL) levels were the highest in the amenorrhoea group (P < 0·05). The same trend existed in total cholesterol and non- high-density lipoprotein-cholesterol (HDL) levels, although there was no statistical significance (P > 0·05). Subjects with a BMI<25 kg/m(2) had higher values of follicle stimulating hormone (FSH), LH, LH/FSH and prolactin (P < 0·001) than the other two groups. The levels of TG, LDL and non-HDL and the indices of glucose and insulin metabolism increased with the change in BMI (P < 0·001).
  
  
  CONCLUSIONS
  The amenorrhoea group had severe endocrine and metabolic abnormalities, which appeared to be related to latent long-term complications and higher morbidity. The degree of dysbolism was positively associated with the change in BMI.
