In AES group and NIH group:
Patients are younger,
Besides higher T, higher FSH and LH level.
LH/FSH ratio is also higher significantly
Similar in both groups:
Insulin levels are higher than that of non- groups
Prevalence of Diabetes family history is significantly higher
More risk of long-term complications
Clinical study of Chinese PCOSClinical study of Chinese PCOS
The increased level of FSH and hypersensitivity
caused by hyperandrogenism can promote the
development of mutiple pre-antral follicles. This
may be the reason of the morphological change in
PCOS.
Elevated LH level will stimulate the production of
androgen and form the vicious cycle which will
aggravate the ovulatory dysfunction.
Sarma HN. 2005
DiscussionDiscussion
A strong association between hyperandrogenism and
metabolic syndrome, independent of obesity and insulin
resistance. Hyperandrogenism is the independent risk factor
of CVD
NIH PCOS is associated with a more adverse metabolic profile. The prevalence of obesity and insulin resistance is higher in NIH group. The risk of CVD and DM was increased.

Cussons 2008, Moran L 2009 Goverde AJ, 2009
DiscussionDiscussion
Our present results: both NIH and AES PCOS are associated with a more adverse metabolic profile. The insulin level are higher than that of non- groups, the insulin sensitivity was impaired in these subgroups. Prevalence of Diabetes family history is significantly higher.
PCOS without polycystic ovaries (non-PCO ) had higher
cholesterol and low-density lipoprotein, had a higher
incidence of developing long-term complications.

DiscussionDiscussion
Androgen excess plays an important role in the
pathophysiological process and has crucial significance ,but in clinic, how to determine androgen excess ?
