BACKGROUND: The cryopreservation process induces osmotic stress, membrane changes and production of reactive oxygen species resulting in damage to the spermatozoa. Together, the presence of oxygen in the extender aggravates the oxidative stress that further reduces the cryosurvival rate of sperm...

Bulls in Artificial Insemination (AI) Centres are generally trained with false mounting (FM) activity in order to improve the quality of semen. 360 ejaculates were collected via artificial vagina from twelve bulls. The bulls were subjected to each group according to the number of FM activity (FM-...

Objective of this study was to compare cryosurvival of epididymal (EP) and electroejaculated (EE) sperm cryopreserved in liposome- or egg yolk- based extenders. Aliquots of EE sperm (n = 10 bulls) were cryopreserved with a liposome- (Optixcell; EEO) or egg yolk-based extender (Botubov; EEB). Bulls...

The aim of the present study was to evaluate the effect of sperm selection by single-layer centrifugation (SLC) performed before freezing on sperm quality after thawing of Fleckvieh bull semen. Ejaculates from 22 bulls were collected by artificial vagina and divided into two aliquots. One aliquot...
