The cases will be randomly assigned to receive one of the four treatment modalities by using computer generate random table and sealed envelop Group A: they got cabergoline (0.25 mg twice weekly) for three months. Group B: they received metformin 500 mg three times daily for three months. Group C: they received Clomiphene citrate (50mg twice daily for 5days) from second day of menstrual cycle for three months. Group D: they got placebo once per day during the three months follow up period Serum prolactin (PRL), basal follicular stimulating hormone (FSH), basal luteinizing hormone (LH), basal serum estradiol (E2) and midluteal serum progesterone (P) were measured before the start of the treatment.
