Long term efficacy of metformin in overweight−obese PCOS

| Hot topics

Metformin is widely used in the treatment of women with polycystic ovary syndrome (PCOS), yet data supporting its long term efficacy in this population are scant. In this retrospective cohort study, Jensterle et al. report data from their centre’s longitudinal follow-up (for up to 10 years) of women with a diagnosis of PCOS, concomitant overweight/obesity, and normal glucose handling at baseline.
