[Different types of menstrual cycle and their significance in Chinese women diagnosed with polycystic ovary syndrome according to the Rotterdam consensus criteria].
OBJECTIVE
To analyze the clinical and metabolic characteristics of Chinese women with different menstrual types. All the women were diagnosed with polycystic ovary syndrome according to the Rotterdam consensus criteria.


METHODS
A total of 2100 patients were divided into three groups: amenorrhea, oligomenorrhea and regular menstruation. The metabolism and endocrine indices were determined and compared among three groups.


RESULTS
(1) The incidences of hirsutism and PCO were obviously higher in the amenorrhea group than in the oligomenorrhea group (P < 0.01). (2) The amenorrhea group had the highest level of serum testosterone while the oligomenorrhea group had the lowest. Moreover, the level of luteinizing hormone (LH) was higher in the amenorrhea group than in the other two groups (P < 0.01). However the ratio of LH/FSH increased significantly in the regular menstruation group (P < 0.01). (3) The value of 2 h blood glucose was the highest in the amenorrhea group (P < 0.01).


CONCLUSIONS
PCOS patients with diverse types of menstrual cycle show different clinical manifestations and metabolic and endocrine characteristics so that the choice of treatment should be individualized.
