In the case of sudden death or injury stallion reproductive system or necessary castration preventing the collection of semen can to preserve the genetic potential of exceptional individuals take advantage of epididymal sperm. Virtually the only way, how to preserve fertilizing sperm POTENTIAL for long time IS cryopreservation. However, this process induces irreversible changes that are the cause of the reduced number of sperm capable of fertilization after thawing. Epididymal sperm cells have properties different from the ejaculated, harder to keep. Therefore, they are constantly looking for ways to streamline their cryopreservation.
GENERAL most commonly used cryoprotectants include glycerol and Egg yolk. Despite the positive effects is glycerol toxic to cells and Egg yolk also contains ingredients that act on sperm metabolism negatively. Increasing the efficiency of cryopreservation protocols themselves likely to be achieved by replacing toxic components while leveraging industry-produced active yolk fractions.
Submitted dissertation topic itself will deal with the use of cholesterol-loaded cyclodextrins Along with low density lipoproteins, the cryopreservation of epididymal sperm.
Main method: HPLC, Western blot, electrophoresis, fluorescent labels, computer-assisted sperm analysis (CASA).
