Metformin in women with PCOS, CONS

  • Marie L. Misso
  • Helena J. Teede
Pros and Cons in Endocrine Practice


Metformin has a potential role for insulin resistance in polycystic ovary syndrome(PCOS) and has demonstrated efficacy in diabetes. There are a large number of studies and evidence syntheses comparing metformin with control, lifestyle interventions, the oral contraceptive pill, and clomiphene citrate; however, there is still uncertainty about the effectiveness of metformin in women with PCOS. Here we present a systematic overview of the evidence for the use of metformin in women with PCOS. The evidence suggests that metformin continues to have an unclear roll in PCOS until further well designed; methodologically rigorous effectiveness studies with large sample sizes are conducted, and these should include women across the body mass index (BMI) range.
