OBJECTIVE: To compare the therapeutic effects of metformin (Met) and laparoscopic ovarian drilling (LOD) in clomiphene and insulin-resistantpatients with polycystic ovary syndrome (CIRPCOS). METHODS:A total of 110 patients were randomly divided into two groups. One group was administered Met (n = 55), while the other group underwent LOD (n = 55). Rates of ovulation, pregnancy, and abortion were compared between both groups. RESULTS:Rates of normal menstruation, ovulation, and pregnancy in the LOD group were higher than in the Met group: 76.4% (42/55) vs. 58.2% (32/55), P < 0.04; 50.8% (11/258) vs. 33.5% (94/281), P < 0.001; 38.2% (21/55) vs. 20.0% (11/55), P < 0.03. The difference in the early abortion rate between both groups was not statistically significant. CONCLUSIONS: Although Met can significantly improve a patient's insulin resistance, we found that in patients diagnosed with CIRCPOS, LOD can be much more effective in improving rates of normal menstruation, ovulation, and pregnancy.
