The way to increase reproducibility of the results of cryopreservation of the mammalian embryos that enables to cut to a minimum influence of the individual properties of both: biological object and features of the concomitant technological operations was offered. Significant influence of a native embryos condition on their viability parameters was established at estimation of the chosen way of cryopreservation. Estimation of efficiency of cryopreservation of the bovine embryos, determined from a parameter of relative acceptability of the deconserved embryos to those for native ones has enabled to lower influence of individual properties of embryos and conditions of carrying out transplantation more than twice (dispersion is 79.92%).

Key words: reproducibility, embryos of mouse and bovine, estimation of efficiency, cryopreservation, individual properties.
