The importance of sperm diluents of different types of farm animals in the process of the cryopreservation

Purpose: to systematize and analyze scientific information about diluents of sperm of farm animals in the process of its cryopreservation, taking into account specific featuresAssisted reproductive technologies are extremely in demand in animal husbandry at the moment, especially with regard to artificial insemination. However, this technology is of priority importance if the sperm is stored for a long period when the sperm is cryopreserved. At the same time, numerous studies have established that the cryopreservation process causes adverse changes in germ cells, which leads to their damage or death, and partially irreversible damage to the morphological structures of cells occurs. To obtain high results from the use of frozen-thawed sperm, it is necessary to prevent damage to spermatozoa. In this regard, the use of sperm diluents is urgent. Each type of animal sperm has its own distinctive parameters volume, concentration, chemical composition, osmotic pressure, pH, etc. Therefore, it is difficult to develop a universal sperm diluent suitable for each type of animal.
