Background and Objective: Patients with polycystic ovary syndrome (PCOS) treated with gonadotrophins often have a polyfollicular response and are exposed to the risks of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy. The aim of the present study was to evaluate the efficacy of laporoscopic ovarian drilling (LOD) on the endocrinologic, clinical parameters and reproductive outcome of clomiphene- resistant anovulatory infertile patients with PCOS using monopolar diathermy. Material and methods: Fortyfive clomiphene- resistant anovulatory women with PCOS have participated in the study. Serum testosterone (T), follicule stimulating hormone (FSH) and luteinizing hormone (LH), fasting insulin and glucose levels, body mass indexes, modified Ferriman Gallwey (FG) hirsutism scores of the subjects are recorded before and after the procedure. Endocrinologic and clinical profile and reproductive outcome of the patients were analysed. Results: Ovarian drilling was successfully employed without any surgical complications and mean ± S.D. duration of followup time was 29.73 ± 10.64 months. In the follow- up period 93.3% of the subjects were recorded to have regular cycles and 64.4% pregnancy rate was achieved, spontaneously. The serum levels of T, free T, LH, LH:FSH ratio, insulin and FGscores were significantly reduced after LOD, although glucose levels and glucose/insulin ratio remained unchanged. Conclusion: In choosing ovulation induction method in clomiphene resistant PCOS patients, LOD may avoid or reduce the risk of OHSS and multiple pregnancy than gonadotrophins with the same success rate of conception. The high pregnancy rate, and economic aspect of the procedure offer an attractive management for patients with PCOS.
