Stages of spermatogenic cell cycle were described and classified in Baladi rabbits according to the shape, migration of the spermatid, release of spermatozoa and presence of meiotic figures of spermatocytes. Quanti fication of the cells of the cycles were carried by calculating each type and relating it to the number of Sertoli. The diameter of the seminiferous tubules was measured. The three indecies, stages of the cycle, the Sertoli cell ratio and the diameter of semini ferous tubules were presented for pathophysiological evaluation of the spermatogenesis in rabbit as an ex perimental animal.
