Effects of water- and lipid-soluble antioxidants on turkey sperm viability, membrane integrity, and motility during liquid storage
TLDR
Addition of the antioxidants vitamin E, BHT, and Tempo to extended turkey semen improves sperm survival, membrane integrity, and reduces the loss of motility after 48 h storage.About:

Viability, susceptibility to peroxidation and fatty acid composition of boar semen during liquid storage.
TL;DR: It is concluded that the alphaT inclusion in the boar semen diluent increased cell viability through its prevention of an oxidative reduction in the levels of the major polyunsaturated fatty acids, namely 22:6n-3.

TL;DR: In the present trial, exogenous Trolox positively affected post-thaw sperm viability (as motility and mitochondrial membrane potential) in both fractions of the ejaculate.

Motility and fertility of bull sperm in whole milk extender containing antioxidants.
TL;DR: Antioxidants generally were not beneficial, except the percentage of motile sperm was improved by 6-11% units when sperm were stored unfrozen or after freezing when 0.5mM of GSH with or without SOD was added, which may have more useful applications in organizations using an egg yolk-based semen extender.

TL;DR: In this article, a multi-channel system for classifying particles in a mixture of particles according to one or more characteristics including a common source of electromagnetic radiation for producing a beam of radiation and a beam splitter for producing multiple beams of radiation for each interrogation location associated with each flow channel of the system.

Effect of antioxidants on preservation of motility,viability and acrosomal integrity of equine spermatozoa during storage at 5°c
TL;DR: Adding the enzyme scavenger, catalase, or a variety of lipid- and water-soluble antioxidants did not significantly improve the maintenance of motility during liquid semen storage at 5 degrees C.

Spontaneous lipid peroxidation and production of hydrogen peroxide and superoxide in human spermatozoa. Superoxide dismutase as major enzyme protectant against oxygen toxicity.
TL;DR: The results suggest that superoxide dismutase plays the major role in protecting human spermatozoa against lipid peroxidation, and the superoxide Dismutase activity of a fresh sperm sample appears to be a good predictor of the lifetime (up to the complete loss of motility) of that particular sample, and so may prove useful in semen analysis.

TL;DR: Assessment of the ability of the antioxidants, butylated hydroxytoluene, and vitamin E, to curtail the peroxidative damage inflicted by cells in response to centrifugation revealed a significant improvement of sperm function in the presence of vitamin E.

TL;DR: There was a linear improvement in survival of spermatozoa with increasing dose of antioxidants except for CAT for which doses higher than 200 U mL-1 were toxic.
