[Effect of choriogonadotropin on the ovaries and uterus of infantile rats following treatment of the amygdaloid nuclei].

Experiments were conducted on female rats. The authors studied the effect of choriogonadotropin on the ovaries and uterus following simulation or destruction of the cortico-medial portion of the amygdaloid nuclei. In rats with an intact hypophysis administration of choriogonadotropin after stimulation or destruction of the amygdaloid nuclei led to increase in the number of the vesicular follicles and corpora lutea. In hypophysectomized rats the action on the amygdaloid nuclei failed to influence the choriogonadotropin effect on the ovaries. Changes in the ovaries depended on the total effect of choriogonadotropin and endogenous gonadotropins released into the blood after the action on the amygdaloid nuclei.
