Eligibility
Key inclusion criteria
PCOS was defined according to Rotterdam European Society for Human Reproduction and Embryology (ESHRE) and the American Society for Reproductive Medicine(ASRM) consensus workshop. All patients had at least two of the following three criteria: chronic anovulation, clinical and/or biochemical hyperandrogenism, and polycystic ovaries on ultrasound (USG).
Minimum age
18 Years
Maximum age
No limit
Gender
Females
Can healthy volunteers participate?
No
Key exclusion criteria
The patients who had liver and kidney diseases and using drugs affecting insulin sensitivity and lipid profile and oral contraceptives within the last six months were excluded from the study. Patients with Cushing's syndrome, hyperprolactinemia, diabetes mellitus, thyroid disease, congenital adrenal hyperplasia and androgen-secreting tumors, insufficient LH syndrome and other endocrinopathies were also excluded from the study.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients were assigned to receive lifestyle-intervention (diet and exercise) and metformin (2000mg/day, n= 20, M group) therapy or lifestyle-intervention, metformin plus rosuvastatin therapies (2000mg/day metformin and 10 mg/day rosuvastatin, n= 18, MR group) for 12 weeks.
For statin administration, newly diagnosed PCOS patients with hyperlipidemia and IGT were selected among PCOS patients at high risk for cardiovascular disease. PCOS patients with a LDL-cholesterol level>130 mg/dL and triglyceride (TG) level>150 mg/dL were considered as hyperlipidemic patients. Among hyperlipidemic patients, 18 patients with a LDL-cholesterol level> 160 mg/dL were scheduled to receive additional rosuvastatin therapy. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation used according to their lipid profile. PCOS patients with a LDL-cholesterol level>130 mg/dL and triglyceride (TG) level>150 mg/dL were considered as hyperlipidemic patients. Among hyperlipidemic patients, 18 patients with a LDL-cholesterol level> 160 mg/dL were scheduled to receive additional rosuvastatin therapy. 20 patients received only metformin therapy.

Summary
Brief summary
Objective: We aimed to compare the effects of metformin and metformin plus rosuvastatin combination therapies on hyperandrogenism in patients with polycystic ovary syndrome (PCOS).
Design: A prospective, randomized study.
Setting: University hospital.
Patients: Thirty-eight PCOS patients with hyperlipidemia and impaired glucose tolerance (IGT) were included in the study.
Interventions: Patients were assigned to receive lifestyle intervention and metformin (2000mg/day, n= 20, M group) therapy or lifestyle intervention, metformin (2000mg/day) plus rosuvastatin therapies (10 mg/day rosuvastatin, n= 18, MR group) for 12 weeks. Blood samples were obtained before and after treatment.
Main Outcome Measures: Total and free testosterone, insulin, glucose and hs-CRP levels. Results: After 12 weeks of treatment body mass index (BMI), insulin and glucose levels, HOMA-IR had similar decreaments in both groups (p= 0.5, p=0.97, p=0.74, p=0.94), whereas there was a greater decline of the total and free testosterone levels in MR group (p< 0.001, p= 0.004). DHEAS levels did not change in M group however significantly decreased in MR group after treatment (p=0.8, p=0.002). As expected hsCRP, triglyceride, total and LDL- cholesterol levels decreased more in MR group.
Conclusion: Metformin and rosuvastatin combination therapy was proved to have more favorable effect on hyperandrogenism. Therefore statin therapy in PCOS patients with hyperlipidemia and higher cardiovascular risk can render hyperandrogenism treatment more successful.
