Comparative changes in the diameters of the dominant and first subordinate follicles during the process of follicle selection in women, mares/horses and heifers/cows (day 0 = follicle wave emergence). The dotted horizontal line indicates the diameter at which deviation in follicle growth rates between the dominant and first subordinate follicles occurs (Reproduced with permission from Elsevier, Ginther et al., 2001, Biol Reprod, 65:648–647).
