Metformin treatment (1-2 g/day) improves hyperandrogenism, hyperinsulinemia, and menstrual cyclicity in nonobese women with PCOS primarily by increasing hepatic insulin clearance and reducing abdominal adiposity, without significantly altering whole-body insulin sensitivity.
For nonobese women with PCOS, metformin (1-2g/day) can effectively lower testosterone and improve menstrual cycles by helping the liver clear insulin faster, rather than by changing how muscles use glucose. This suggests that even without weight loss or improved muscle sensitivity, hormonal balance can be restored.
Metformin improved hyperandrogenism, hyperinsulinemia, and menstrual cyclicity, most likely through its positive effect on insulin clearance and abdominal adiposity. Thus, similarly to obese PCOS women, nonobese PCOS subjects with anovulation may also benefit from metformin treatment.
Why this rating
Randomized controlled trial comparing active treatment to standard care, though sample size is small (n=17).
