background: human sperm cryopreservation has proven to be very valuable. cryopreservation has effects on function, morphology and percentage of fertilization capacity of human sperm. also, it has been revealed that cryopreservation has a role in sperm dna fragmentation and infertility. in this study, viability, motility, dna fragmentation and for the first time, intracellular nitric oxide asses...
متن کاملAvian semen cryopreservation: what are the biological challenges?
The value of the ability to cryopreserve and store germplasm has long been recognized for indefinite preservation of genetic material, especially for at-risk populations. In contrast to domestic livestock species, cryogenic storage of poultry semen is not reliable enough for germplasm preservation. The relatively low fertilizing ability of frozen/thawed poultry sperm most likely results from ph...
متن کاملThe Effect of Cattle Seminal Plasma Crude Protein on the Cryopreservation of Goat Semen
This study aimed to improve the quality of cryopreserved goat semen for artificial insemination by the addition of cattle seminal plasma crude protein. Semen collected from cattle and centrifuged to obtain seminal plasma. Then it was purified to obtain the crude protein. The diluent used in this study was milk-yolk. There were three groups, control group without crude protein (P0), the addition...
متن کاملStorage of poultry semen.
Methods of semen collection and artificial insemination (AI) in poultry, requirement for diluents, methods of liquid and frozen storage of avian semen and evaluation of spermatozoa after storage for fertilizing ability are reviewed. Frozen storage of semen from non-domestic birds is also briefly discussed.
