- Abstract
The reproductive system is permanently subjected to the action of a number of factors, which influence it positively or negatively. Therefore, the purpose of the research whose results are presented in this paper was the study of the influence of the oxidative and nociceptive stress on the semen and the reproductive system of breeder bulls and estimating the possibility of diminishing the consequences of the influence of these factors. In order to achieve the proposed purpose, microscopic, physiological, biochemical and statistical methods were used. These research methods enabled to determine that during the technological stages of cryopreservation of the bull sperm, the oxidative stress of spermatozoa causing morphological changes and decreasing the indices which characterize the functional state of reproductive cells takes place. In the case of the animals’ nociceptive stress, a spermatogenesis disorder occurs, which is expressed by the tendency of spermatozoa to develop in a typical or atypical direction. Also, under the stress, the indices which characterize the functional state of spermatozoa (mobility and longevity) are decreased, and antioxidants of natural provenance can be used to reduce the negative consequences of stress. The research results have shown the action of stress at the technological stages of cryopreservation of semen and the fact that oxidative stress is one of the essential deteriorating factors in the process of sperm cryopreservation; the animals’ nociceptive stress negatively influences the spermatogenesis process by conditioning an increased number of gametopathies, predetermined by reproductive cell vulnerability in the spermatogonium division phase, and lowering the functional indices of reproductive cells; the variability of cortisol content in blood plasma and malonic dialdehyde content adequately elucidates the intensity of the organism’s response and cryogenic changes to the action of the stress factor; to diminish the negative consequences of oxidative stress, steroid glycosides can be included in the medium for cryopreservation as antioxidants.
