Condition
Polycystic ovarian syndrome
Intervention
Primary outcome was the comparison of insulin resistance in polycystic ovarian syndrome and controls. Venous blood was taken for measurement of insulin and glucose levels, and insulin resistance was calculated by HOMA-IR (insulin x glucose /22.5).
Secondary outcome was the biological variation of insulin resistance in polycystic ovarian syndrome and controls. Insulin resistance was calculated by HOMA-IR as above, and calculation of biological variation was done on 10 consecutive HOMA-IR taken at 4-day intervals.

Eligibility
Participant inclusion criteria
The diagnosis of PCOS will be based on evidence of hyperandrogenemia (Free androgen index > 8, with a history of oligomenorrhea and hirsutism or acne. Non classical 21-hydroxylase deficiency, hyperprolactinemia, and androgen secreting tumors will be excluded by appropriate tests before the diagnosis of PCOS will be made. Transvaginal ultrasound will also be performed to confirm the diagnosis of PCOS
