The rabbit spermatogenesis was investigated in dynamics with morphology of testicular tissues being analysed. Allocation
characteristic of spermatogenous epithelium cells in spermatic ductules was examined for 19 age groups of rabbit males aged from 10 days
to 12 months. The availability of three types of spermatogonia A, intermediate and  was analysed. In has been determined that the age
from 10 days to 4 weeks is optimal for isolation of testis stem cells, when rabbit spermatogonia are represented by spermatogonia of
A-type only.
