Variation of existence and location of aquaporin 3 in relation to cryoresistance of ram spermatozoa [PDF]
Frontiers in Veterinary Science, 2023 Introduction and objectiveOsmotic changes during the process of freeze-thawing involve changes in the location of aquaporins (AQPs) in membrane domains of spermatozoa.

Canine Spermatozoa—Predictability of Cryotolerance
Animals, 2022 Markers of freezability allow the selection of ejaculates of good freezability. So far, most investigations were conducted in boars, bulls, rams and horses, with high economic interests triggering the efforts. The progress in dogs is comparably slow.

Influence of Dried Egg Yolk with or without Taurine in Extender on Sperm Characteristic of Cryopreserved Buffalo Semen [PDF]
Journal of Animal and Poultry Production, 2021 The objective of this study is to determine the influence of dried egg yolk (DEY) powder on freezability of semen buffalo as an alternative of fresh egg yolk (FEY) with or without taurine. Semen was collected from five buffalo bulls with total motility (≥

Lyophilized seminal plasma can improve stallion semen freezability
Indian Journal of Animal Sciences, 2020 The aim of this study was to evaluate the effect of lyophilized seminal plasma (LSP) on stallion semen freezability. Seminal plasma from 30 stallions was lyophilized to obtain a pool of LSP. Fifteen ejaculates from five stallions were supplemented before

FREEZABILITY, ACROSOME STATUS AND CONCEPTION RATE OF FROZEN BULL SPERMATOZOA AT DIFFERENT AGES SUPPLEMENTED WITH CAFFEINE [PDF]
Journal of Animal and Poultry Production, 2001 Semen was collected from five of each of young (3-5 years) and old (6-10 years) Friesian bulls and extended with tris-yolk fructose extender (1 semen: 20 extender). The extended semen was cooled to 5ºC over 2 hours, then frozen in straws. After 24 hours,

Proteomic characterization of fresh spermatozoa and supernatant after cryopreservation in relation to freezability of carp (Cyprinus carpio L) semen. [PDF]
PLoS ONE, 2018 Our recent studies suggested that the freezability of carp semen is related to seminal plasma protein profiles. Here, we aimed to compare the spermatozoa proteomes of good (GF) and poor (PF) freezability semen of carp.

Reduced glutathione and cysteine hydrochloride on crossbred bull semen [PDF]
, 2012 Over the last few years, good quality freezable semen was not utilized effectively due to less knowledge about the freezability of semen. One reason is the lack of sufficient antioxidants in the seminal plasma and semen extender.
