Serum estradiol correlated with maximum follicle diameter in normal women but not in women with Overt POI. (A) Each point represents the findings in 1 of 10 normal women with regular menses examined during the follicular phase. Two congruent points are noted by (2). (B) Each point represents the findings in a patient with overt POI who had an ovarian follicle detected by sonogram (37 sonograms in 27 patients). There are 8 congruent points (Nelson et al., 1994).
