[Cytological, morphological and functional changes of Russian sturgeons's (Acipenser guldenshtadti) sperm cells after cryopreservation].

The article presents some experimental results concerning the problem of genetic conservation of valuable and endangered animal species. Biotechnical development of the cryopreservation of spermatic cells for the purpose of their extended storage at low and ultra low temperatures is a priority line of the investigations in the topical area and implies creation of animal genomes cryobanks. It is known that water crystals of plasma and the cell itself often cause the spermatholysis in the course of freezing.
