Corey（'30）和Wislocki（'31）分别研究了大鼠和兔子，确定了这些动物第一次对性腺刺激激素产生显著反应的大致年龄。上述工作者的发现与Hargitt（'30）和艾伦（' 04）关于各自物种卵巢出生后发育的研究相关联，表明对stiinulatioii的第一次典型反应的时间与卵巢卵泡中形成良好的窦的出现相一致。在对未成熟母猪进行实验排卵研究之前，认为有必要确定卵泡发育连续阶段发生时动物的大致年龄和体重，以及卵巢在不同阶段对性腺刺激影响的反应能力。
Corey ( '30), working with the rat, and Wislocki ( '31), with the rabbit, determined the approximate age at which these animals first gave marked rcsponses to gonad-stimulating hormones. A correlation of the findings of the above workers with the studies of Hargitt ( '30) and Allen ('04) on the postnatal iievelopnient of the ovary in the respective species indicates that the time of first typical rcsponses to stiinulatioii coincides with the appearance of well-formed antra in the follicles of the ovary. Preliminary to studies o n experimental ovulation in the immature sow, it was deemed necessary to determine the approximate age and weight of the aninials at the time the successive stages of follicular development occur and also the ability of the ovary to respond to gonad-stimulating influences while in the different stages.
