El IR ovárico presentó valores inicialmente altos que descendieron posterior al tratamiento. El ICC presentó correlación directa y significativa sobre el IR ovárico, mientras el peso corporal, IMC y la glicemia 120 min influenciaron sobre las cifras de TAS. Conclusión: Se debe considerar al metformin como una alternativa terapéutica para el manejo integral de la paciente con síndrome de ovario poliquístico.
