Changes in the number (mean ± SEM) of small antral (200 to 340 μm), medium antral (350 to 500 μm), and large antral (>500 μm) follicles in mice (n = 3). Data were centralized to the day of estrus and analyzed between the morning of estrus and the evening of the following proestrus (i.e., 12 h before next estrus). Data from 24 h before and after the days of analysis are shown for completeness. P: Proestrus, E: Estrus, M: Metestrus, D: Diestrus. Asterisks (*) indicate differences between medium and large antral follicles (P < 0.01), whereas a dot (.) indicates a tendency for a difference (P = 0.06). The number of small antral follicles differed (P < 0.01) from the number of medium and large antral follicles on all days of the estrous cycle.
