Assessment of Ageing-Dependent Effects on Sperm Functions following Semen Cryopreservation
Journal Title: Veterinary Medicine – Open Journal - Year 2017, Vol 2, Issue 2
Abstract
There has been an increased improvement in the cryopreservation protocol of semen, which contributes to the preservation of genetic resources.1,2 Cryo-induced damage to spermatozoa is attributed to membrane deterioration caused mainly by the formation of intracellular ice and increased oxidative stress, resulting in a loss of the sperm fertilizing ability.3 It is noteworthy that ageing-dependent processes in frozen-thawed semen occur in different sperm compartments, and are associated with membrane modifications of specific lipid-protein interactions, activation of an apoptosis-like mechanism and reduced genomic integrity, which consequently compromise sperm cryo-survival.4,5 Moreover, ageing is a natural process occurring in sperm cells during semen preservation, and there is no single sperm test that can effectively predict the fertilizing capacity of semen following the different reproductive technologies.6
