Objective: To compare the effect of clomiphene citrate, metformin, and lifestyle modification on treatment of patients with polycystic ovary syndrome (PCOS).
Design: Prospective randomized double-blind study.
Setting: University-based infertility clinic and research center.
Patient(s): Three hundred forty-three overweight infertile women with PCOS.
Intervention(s): The participating women were assigned to four groups: clomiphene (n = 90), metformin (n = 90), clomiphene + metformin (n = 88), and lifestyle modification (n = 75). The patients in each group received standardized dietary and exercise advice from a dietitian.
Main Outcome Measure(s): The primary outcome variables were change in menstrual cycle, waist circumference measurements, endocrine parameters, and lipid profile. The main secondary outcome variable was clinical pregnancy rate.
Result(s): The clinical pregnancy rate was 12.2% in clomiphene group, 14.4% in metformin group, 14.8% in clomiphene + metformin group, and 20% in lifestyle modification group. Lifestyle modification group achieved a significant reduction in waist circumference, total androgen, and lipid profile.
Conclusion(s): Lifestyle modification improves the lipid profile in PCOS patients. Therefore, lifestyle modification may be used as the first line of ovulation induction in PCOS patients. (Fertil Steril (R) 2010; 94: 216-20.
