The impact of insulin resistance on the outcome of laparoscopic ovarian electrocautery in infertile women with the polycystic ovary syndrome

In this study we assessed how insulin resistance affects pregnancy rates in infertile women with the polycystic ovary syndrome (PCOS) treated with laparoscopic ovarian electrocautery. Sixty-four PCOS women were included in the study in a consecutive fashion. Following the CIGMA (continuous infusion of glucose with model assessment) test, 28 women were classified as insulin resistant and 36 women as non-insulin resistant. After the ovarian electrocautery patients were observed for 12-18 months. If pregnancy did not ensure, they were referred for one or more cycles of in vitro fertilization (IVF). Following ovarian electrocautery the non-insulin-resistant women more frequently achieved a regular menstrual cycle and ovulation than the insulin-resistant PCOS women. Consequently 18 (50%) of the non-insulin-resistant PCOS women achieved a pregnancy versus only five (18%) of women in the insulin-resistant PCOS women. Consequently 18 (50%) of the non-insulin-resistant PCOS women achieved a pregnancy versus only five (18%) of women in the insulin-resistant PCOS group. Following treatment with both ovarian electrocautery and IVF, 27 (75%) of the non-insulin resistant PCOS women achieved a successful pregnancy, while 13 (46%) of the insulin-resistant PCOS group achieved this. In conclusion, insulin resistance may be an important marker of a poor outcome of treatment in POCS infertility. Further studies are needed to evaluate the possible effect of treatment alternatives to alleviate the unfavourable influences of insulin resistance and hyperinsulinemia on ovulation induction in PCOS women.
