2. FIGURE 1
Follicular diameter profiles for a woman who exhibited two follicular waves during the interovulatory interval as determined by the (A) Identity Method and (B) Non-Identity Method. Note that only follicles that grew to ≥8 mm could be individually identified from day-to-day using the Identity Method. Follicles that grew to ≥6 mm were identified using the Non-Identity Method. (A), Each follicle is represented by a different symbol. (B) ■ = largest follicle, □ = second largest follicle, and * = third largest follicle.

4. FIGURE 3
Day-to-day profiles (mean ± SEM) of the number of follicles ≥5 mm detected (■) and the diameter of the largest follicle of each wave (Non-Identity Method, ○) for women exhibiting (A) two waves (n = 34) and (B) three waves (n = 16) during one interovulatory interval. Asterisks indicate follicle number data overlap.
