Ligation of the largest preovulatory follicle (F1) or the second largest preovulatory follicle (F2) delayed terminal oviposition for at least 2 h. Ligation of the fourth or fifth largest preovulatory follicle had no effect on the time of terminal oviposition. The conclusion reached was that some factor produced by the most mature follicles in the ovarian hierarchy influenced the timing of oviposition. Since the terminal oviposition occurs independently of ovulation, the authors concluded that the influence of the F1 and F2 follicles was independent of any preovulatory endocrine changes.
结扎最大的排卵前卵泡（F1）或第二大排卵前卵泡（F2）会使终末产卵延迟至少2小时。结扎第四或第五大排卵前卵泡对终末产卵时间没有影响。得出的结论是，卵巢等级体系中最成熟卵泡产生的某些因素影响了产卵时间。由于终末产卵独立于排卵发生，作者得出结论，F1和F2卵泡的影响独立于任何排卵前的内分泌变化。
