[The effect of destruction and stimulation of the lateral nucleus of the septum pellucidum on the structure and functions of the ovaries and the mechanism of such influences].
The experiments on the immature female rats were carried out to show the effects of damage or stimulation of the lateral septal nucleus (LSN) on the ovary function and its response to chorionic gonadotrophin. The damage of the LSN decreases the ovary weight, but enlarges mature ovarian follicles and increases the estrogen production. LSN lesions in hypophysectomized rats have no effect on the ovary and uterus weights as compared to hypophysectomized ones, but decrease the size of mature ovarian follicles against a background of hypophysectomy or LSN lesions. Damage of the LSN increases ovary and uterus sensitivity to the chorionic gonadotrophin injections. A conclusion is drawn on the existence of parahypophysial way to transfer the influence of LSN on the rat ovaries. The possible mechanisms of LSN influence on the reproduction system of female rats is under discussion.
