Abstract: Information on dimensions of seminiferous tubules of avian species is inadequate compared to mammalian species. The present study aimed to evaluate some parameters of seminiferous tubules of domestic chicken (Gallus gallus domesticus) as an avian species. A total of 30 birds were used for the study, comprising of 10 birds per each of the four reproductive cycles, namely pre-pubertal, pubertal, adult, and aged. The seminiferous tubule diameter of the aged group had the highest mean diameter (305.974 ± 26.24 ±se) even though there was no significant difference between the age groups (P>0.05). However, a significant difference (P<0.005) for the aged groups was observed for both the seminiferous tubule lumen diameter (116,273 ± 14.47 ±se) and the mean epithelium height (121.017 ± 8.89 ±se) than the pre-pubertal, pubertal, and adult age groups. The present study showed that spermatogenesis gradually declined in aged birds by presenting wider seminiferous tubule lumen which could be due to the high rate of germ cells apoptosis and fall in androgen levels, which are common indicators of aging as seen in both avian and mammalian species studied. The development of stereological research techniques yields quantitative data that is essential for creating associations between physiological and biochemical data.
