Women with PCOS have been observed to be potential diabetics.Recently,American Diabetes Association has suggested screening of women with PCOS for HbA1C.

In view of recent suggestion of American Diabetes Association(ADA)to screen women with PCOS for HbA1C,we intend to study its prevalence in all categories of obesity in women with PCOS.

Women with PCOS by Rotterdam criteria will be screened for insulin resistance by using different techniques or tests.

Further, the sensitivity and specificity of HbA1C will be compared with sensitivity and specificity of other insulin resistance markers such as OGTT, Free androgen index, free testosterone, fasting insulin to glucose ratio, HOMA-IR and HOMA-B-CELL.

Inclusion Criteria:

1. BMI of 25-35 Kg/Mt2
2. Atleast three of the Rotterdam criteria for diagnosis of PCOS.
3. Subjects with well stabilized Thyroid,if they had documented evidence of previousthyroid disorder.

Exclusion Criteria:

1. Subjects with documented diagnosis of Metabolic Syndrome.
2. Subjects with laparocopic and histopathologic diagnosis of Endometriosis. 3Subjects with Primary hyperprolectineamia.

4.Subjects with basal FSH >/=15mIU/ml. 5.Subjects with continuously elevated 17-0h-p.

This population will have subjects with diagnosis of PCOS,by Rotterdam criteria regardless of complain(s)
