La importancia de estos factores puede variar en las mujeres afectadas. Entre los principales factores implicados se describen: Al mismo tiempo hay un aumento en la progestlnas y amplitud de los pulsos secretorios. Por tanto, la mujer con SOP tiende a tener niveles bajos de SHBG y esto enmascara la magnitud del exceso de testosterona cuando se mide ls testosterona total.
