This study was undertaken to investigate the morphological changes between normal and atretic follicle after gamma irradiation and treatment of follicle stimulating hormone (FSH). The ovaries of each group of treated immature mice were prepared the paraffin sections after 0,6,12, and 24 hours (hrs) of those treatment. Hematoxylin-eosin (HE) stain, reticulin stain, and terminal deoxynucleotidyl transferase (TdT)-mediated dUIP nick end labeling (TUNEL) immunohistochemical stain were performed on the each paraffin sections. As the results of HE staining, the condensed nuclei of oocytes were observed in the atretic primordial follicles, on the other hand the condensations of granulosa cell nuclei were prominent in the atretic primary, preantral, and antral follicles. Only the granulosa cells of atretic follicle were stained specifically with TUNEL staining but not stained in the theca cells, which suggested granulosa cells degenerated through apoptosis. In the reticulin staining, the basement membranes of atretic follicle which was stained weakly showed irregular structure and detachment from the follicles. The ratio of normal to atretic follicle in control and FSH treated group was about 33% but this ratio increased rapidly over 90% in the 6, 12, and 24 hrs group after the irradiation. It could be suggested that the gamma irradiation is the useful tool for the induction of follicle atresia and immunohistochemical staining methods are essential in the study of follicle atresia.
