[Dynamics of spermatogenesis in albino mice of different age groups]

The age dynamics (beginning from the 2nd to the 455th days) of histomorphological indicators of testes in mongrel white mice in the process of postnatal development has been investigated. The age phases of spermatogenesis development in white mice and the transitional periods between them, which correspond to 6-15, 25-30, 175, 335 days are determined. An interrelation of spermatogenesis indicators during the postnatal development of white mice is described.
