Cryopreservation is the most efficient method for long-term preservation of mammalian
sperm. However, freeze-thawing procedures may strongly impair the sperm function and …

Reactive oxygen species (ROS) have been proposed as one of the main causes of the
impairment of fish spermatozoa integrity and functionality during cryopreservation. The high …

Sperm cells can be damaged during the semen cryopreservation process, decreasing their
fertilizing ability. Physical damage and oxidative stress may occur during the freeze–thawing …

This investigation was carried out to study the correlation of sperm quality parameters with
antioxidant and oxidant status of buffalo bull semen during various stages of …

Owing to its redox properties, copper is a cofactor of enzymes that catalyze reactions in
fundamental metabolic processes. However, copper–oxygen interaction, which is a source …

Rooster semen cryopreservation is a useful method to utilize semen samples for artificial
insemination in commercial flocks, but with use of the freezing-thawing process there is a …

Supplementation of cooling medium with some antioxidants could be a helpful way to
improve sperm quality during chilling process. The current study was aimed to assess the …

While the removal of seminal plasma is a routine practice prior to equine sperm
cryopreservation, this fluid contains the main source of antioxidant enzymes able to …

This study investigated whether the activities of four antioxidant enzymes present in jackass
seminal plasma (SP), superoxide dismutase (SOD), catalase (CAT) and glutathione …

The objective of this study was to determine the relationship of enzymatic (superoxide
dismutase, SOD; glutathione peroxidase, GPX; catalase, CAT; and paraoxonase type 1 …
