METHODS: A total of 110 eligible participants were randomly allocated to diagnostic laparoscopy plus metformin therapy (group 1, n=55) or laparoscopic ovarian drilling (group 2, n=55). The t test was used for mean comparisons of hormonal-metabolic parameters and OGTT values before and after treatment. The chi(2) test was used for comparisons of ovulation, pregnancy, and abortion rates.
RESULTS: Groups 1 and 2 showed a significant decline in testosterone, insulin-like growth factor-1 (P<0.001 vs P<0.001), and luteinizing hormone (P<0.05 vs P<0.001), while the glucose to insulin ratio was significantly increased (P<0.001 vs P<0.05) compared with baseline. Group 2 patients had more regular cycles and higher rates of ovulation and pregnancy compared with group 1: 76.4% [42/55] vs 58.2% [32/55], P<0.04; 50.8% [131/258] vs 33.5% [94/281], P<0.001; and 38.2% [21/55] vs 20.0% [11/55], P<0.03, respectively. The difference in the early abortion rate between the groups was not statistically significant.
CONCLUSION: Although metformin results in a better attenuation of insulin resistance, laparoscopic ovarian drilling is associated with higher rates of ovulation and pregnancy. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
