Rate of spermatogenic cell apoptosis in the testis of domestic chicken (Gallus gallus domesticus) at different age groups.

In both normal and pathological conditions, excess spermatogenic cells in the testicular tissue are known to be removed by the mechanism of apoptosis. There are a few studies on spermatogenic cell apoptosis in avian species. Therefore, the purpose of this study was to evaluate the rate of spermatogenic cell apoptosis in three different age groups of the local domestic chicken (Gallus gallus domesticus).
