Why the study?
Does ovarian vascular impedance and hormone levels differ between women with normal menstrual cycles and those with PCOS or hypogonadotropic amenorrhea during IVF stimulation?

May signal distinct ovarian responses in anovulatory women undergoing IVF; leaves open whether impedance tracking refines stimulation strategies.
Does ovarian vascular impedance and hormone levels differ between women with normal menstrual cycles and those with PCOS or hypogonadotropic amenorrhea during IVF stimulation?
Women with PCOS or hypogonadotropic amenorrhea lack the normal decrease in ovarian vascular impedance and increase in hormone levels seen in normal women during IVF stimulation.
Schurz et al. (1993) studied this question.
