title: Metabolic and endocrine effects of metformin and metformin plus cyclic medroxyprogesterone acetate in women with polycystic ovary syndrome.
abstract: OBJECTIVE
  To evaluate the metabolic and endocrine effects of treatment with cyclic medroxyprogesterone acetate (MPA) plus metformin compared with metformin alone in women with PCOS.
  
  
  METHODS
  In this prospective randomized study of women with PCOS, 20 women received 850 mg of metformin twice a day, and 20 women received 850 mg of metformin plus 5 mg of MPA twice a day. Body mass index, hormonal and lipid blood profiles, homocysteine blood level, and insulin sensitivities assessed by homeostasis model assessment (HOMA) were recorded at baseline and at 3 months.
  
  
  RESULTS
  Total cholesterol levels decreased in the metformin plus MPA group (P=0.002) but did not change significantly in the metformin group (P=0.159). While homocysteine levels remained unchanged in the metformin plus MPA group, they increased significantly in the metformin group (P=0.002).
  
  
  CONCLUSIONS
  There were no adverse effects of short-term cyclic MPA plus metformin treatment on metabolic parameters or insulin resistance in patients with PCOS over a 3-month treatment period.
