Different effects of amygdaloid lesions on compensatory ovarian hypertrophy in cyclic and prepubertal female rats.
Cyclic and 28-day-old immature female rats were hemiovariectomized and partly bilaterally lesioned in the cortical amygdaloid nucleus (CAN). The compensatory ovarian hypertrophy (COH) recorded in the adult females on the 8th day after hemicastration was completely prevented by the amygdaloid lesions. In contrast, damage to the CAN did not alter the ovarian weight in prepubertal females, although COH was also induced in these animals by unilateral ovariectomy.
