To define ovarian follicular kinetics in the equine ovary during anestrus and the breeding season, the follicular population of pony mares was investigated at mid-anestrus and at the beginning and end of the breeding season. There was a clear effect of season on the exit of reserve (primordial and initiated) follicles since at the beginning of the breeding season we noticed a higher mitotic index for the smaller preantral follicles, leading to an accumulation of small and medium antral follicles. In contrast, the ovaries sampled during anestrus or at the end of the breeding season were very similar; only preovulatory development was lacking in anestrous ovaries. However, atresia was unaffected by season.
为了确定母马在乏情期和繁殖季节卵巢卵泡的动力学变化，研究人员在乏情期中期以及繁殖季节开始和结束时对小母马的卵泡群体进行了调查。季节对储备卵泡（原始卵泡和起始卵泡）的排出有明显影响，因为在繁殖季节开始时，我们注意到较小的腔前卵泡有较高的有丝分裂指数，导致中小腔卵泡的积累。相比之下，在乏情期或繁殖季节结束时采集的卵巢非常相似；乏情期卵巢仅缺乏排卵前的发育。然而，闭锁不受季节影响。
