Longitudinal profiles of follicle number and follicle diameter category in women with PCOS-Anov (n = 12) and controls (n = 12). AFC ≥2 mm (mean ± standard deviation) is shown during an anovulatory interval in women with PCOS-Anov (A) and interovulatory interval in controls (B). Mean follicle number per diameter category, expressed as a proportion of AFC ≥2 mm, is also shown over time for both groups (C and D, respectively). Proportions of 2-5 mm (light gray), 6-9 mm (dark gray), and ≥10 mm (black) follicles are presented, with y-axes truncated for better visibility of changes. Abbreviations: AFC, antral follicle count; IOI, interovulatory interval; FP, follicular phase; LP, luteal phase; M, menses.
