Agelin sponges and serum gonadotropins were used for estrous synchronization and hormone treatment, respectively. The increased amount of PAS positive substances found in the examined hypothalamic nuclei after irradiation and hormone treatment seems to stimulate the function of the hypothalmic structures. The results of caryometric analysis in spring sheep also confirm this view. Administration of hormones in combination with irradiation results in increased number of ependyma cells and desquamation of the surface layers
