Follicle diameter profiles (■) and serum concentrations of E2-17β (○) and LH (◊) for women randomized to initiate OC use at 10 mm. Follicles that grew to 10–14 mm and then regressed (A) and grew to >14 mm and then regressed (B) are shown separately. Data are centralized to the day of randomization at 10 mm.

3. FIGURE 2
Follicle diameter profiles (■) and serum concentrations of E2-17β (○) and LH (◊) for women randomized to initiate OC at 14 mm. Follicles that grew to 14 ± 1 mm and then regressed (A), grew to >14 mm and then regressed (B), ovulated (C), or developed into anovulatory follicular cysts (D) are shown separately. Data are centralized to the day of randomization at 14 mm.

Follicle diameter profiles (■, ●) and serum concentrations of E2-17β (○) and LH (◊) for women randomized to initiate OC at 18 mm. Follicles that ovulated (A), formed hemorrhagic anovulatory follicles (HAF) (B), ovulated (follicle 1) and ovulated (follicle 2; C), ovulated (follicle 1) and formed HAF (follicle 2; D), and ovulated (follicle 1) and regressed (follicle 2; E) are shown separately. Data are centralized to the day of randomization at 18 mm.
