Cryopreservation has facilitated advancement of biological research by allowing the storage
of cells over prolonged periods of time. While cryopreservation at extremely low …

Oxidative stress occurs when the levels of reactive oxygen species (ROS) overcome the
antioxidant defenses of the organism, jeopardizing several biological functions, including …

Melatonin has a wide variety of beneficial actions at the level of the gonads and their
adnexa. Some actions are mediated via its classic membrane melatonin receptors while …

The objective was to examine if there are relationships between alterations in sperm
viability, reactive oxygen species (ROS) synthesis, and DNA integrity induced by …

Contents Flow cytometry has become an important technique in sperm evaluation and is
increasingly used both for routine assessment and for research in veterinary science. We …

Cryopreservation harms spermatozoa at different levels and thus impairs their fertilizing
ability. The role of melatonin in protecting spermatozoa from different kind injuries has been …

Redox regulation and oxidative stress have become areas of major interest in spermatology.
Alteration of redox homeostasis is recognized as a significant cause of male factor infertility …

To investigate the hypothesis that oxidative phosphorylation is a major source of ATP to fuel
stallion sperm motility, oxidative phosphorylation was suppressed using the mitochondrial …

We review recent developments in the technology of freezing stallion sperm, paying special
attention to the molecular lesions that spermatozoa suffer during freezing and thawing, such …

Mitochondria have been proposed as the major source of reactive oxygen species in
somatic cells and human spermatozoa. However, no data regarding the role of …
