Arms Assigned Interventions
Experimental: Metformin-CC Drug: metformin HCl (Cidophage®; CID,Cairo, Egypt), CC (Clomid®; Global Napi Pharmaceuticals,Cairo, Egypt),Cairo, Egypt)
metformin HCl 1500 daily for 6-8 weeks then 100 mg CC for 5 days starting from day 3 of menstruation up to 6 cycles.
Active Comparator: Laparoscopic ovarian diathermy (LOD) Procedure: Laparoscopic ovarian diathermy (LOD)
Three-puncture technique. Each ovary was cauterized at four points, each for 4 seconds at 40 W for a depth of 4 mm with a mixed current, using an monopolar electrosurgical needle.

Detailed Description:

All patients in the combined metformin-CC group received metformin HCl (Cidophage®;Chemical Industries Development,Cairo, Egypt), 500 mg thrice daily for 6-8 weeks. Then after the end of this period, they received 100 mg CC (Clomid®; Global Napi Pharmaceuticals,Cairo, Egypt) for 5 days starting from day 3 of menstruation (increased by 50 mg in the next cycle in case of anovulation ). Patients continued treatment for up to six cycles. Metformin was stopped only when pregnancy was documented. All patients in the control group underwent laparoscopic ovarian diathermy, then followed up for 6 months.
