Sperm cryopreservation is one of the most important procedures in the development of
biotechnologies for assisted reproduction. In some farm animals, the use of cryopreserved …

Despite the widespread use of frozen or refrigerated mammalian spermatozoa, their quality
remains low as they are highly sensitivity to injuries during preservation and thawing …

Cryopreservation may reduce sperm fertility due to cryodamage including physical-chemical
and oxidative stress damages. As a powerful antioxidant, melatonin has been reported to …

Objectives: This study aimed to examine the impacts of the wide range of concentrations of
glucose and trehalose on the tris-citric acid-egg yolk-fructose (TCEF) extenders for …

Vitrification of sperm by direct contact with liquid nitrogen is increasing in popularity as an
alternative to conventional (slow) freezing. Although slow freezing is very challenging in …

This study investigated whether the activities of the antioxidant components of donkey
seminal plasma (SP)—both enzymatic (superoxide dismutase (SOD), catalase-like (CAT) …

Objective The aim of the study was to explore the possibility of a better sugar suitable for
storage of goat semen at refrigerated temperature. Materials and method For this …

The current study intended to optimize the concentration of Oxyrase in the semen dilutor and
to evaluate its effect on freezability of spermatozoa of Sahiwal bulls. Supplementation of …

Achai is a small size cattle breed, resilient to harsh and cold environment. Cryopreservation
of Achai bull semen may help to improve its genetics and preserve the germplasm. Reactive …

During cryopreservation, spermatozoa may suffer cold and cryo-induced
injuries―associated with alterations in cell defense systems―that are detrimental to their …
