A Prospective Randomized Trial Comparing the Clinical and Endocrinological Outcome with Rosiglitazone Versus Laparoscopic Ovarian Drilling in Patients with Polycystic Ovarian Disease Resistant to Ovulation Induction with Clomiphene Citrate

Objectives: Rosiglitazone, an insulin sensitizing agent is used currently in women with clomiphene citrate (CC) resistant polycystic ovarian syndrome (PCOS). Our study proposed to compare the efficacy of rosiglitazone and CC with laparoscopic ovarian drilling (LOD) and CC in terms of biochemical effects, ovulation rate and pregnancy rate in patients of PCOS resistant to CC.

Methods: This prospective randomised trial included 43 patients of PCOS resistant to CC. Twenty-two women were assigned to the rosiglitazone (4 mg twice daily) and CC group and other 21 patients underwent unilateral LOD and then received CC and multivitamins. The treatment continued for six cycles in both the groups. The biochemical response, ovulation rate and pregnancy rate over a follow up period of 6 months were compared.

Results: Treatment with rosiglitazone and CC or LOD and CC resulted in increased ovulation (80.8 vs. 81.5%) and pregnancy (50 vs. 42.8%), respectively. There was no statistical difference between the two groups in terms of biochemical response, ovulation rate and pregnancy rate.

Conclusion: To avoid the risk of adverse effects of LOD preference may be given to the use of rosiglitazone and CC therapy in patients of PCOS resistant to CC.
