Abstract
Summary
Electrolytic lesions in pre-optic and anterior hypothalamic areas of the brain induced persistent (frequent) vaginal estrus and uterine hypertrophy in rats examined 25-300 days post-operatively. Gonad weight eventually decreased. Compensatory hypertrophy of ovary after unilateral castration was inhibited in persistent estrous lesioned rat. FSH stores in adenohypophysis were maintained but titers in serum decreased. The results signify that adenohypophysis of persistent estrous lesioned rat loses its capacity to augment secretion of FSH under conditions of enhanced demand (unilateral oophorectomy).
