Human sperm motility and lipid peroxidation in different ascorbic acid concentrations: an in vitro analysis.
Human spermatozoal motility, viability and lipid peroxidation (LPO) have been assessed in Ringer-Tyrode supplemented with different concentrations of ascorbic acid (AA) ranging from 50 to 4000 microM. Ascorbic acid in concentrations below 1000 microM protects spermatozoa from free radical damage as evidenced from improvement in their motility and viability. Concomitantly, there is also witnesse...
متن کاملSperm lipid peroxidation and pro-inflammatory cytokines.
AIM To investigate if interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), interferon-gamma (IFN-gamma) or tumor necrosis factor-alpha (TNF-alpha) are able to stimulate the level of lipid peroxidation of sperm membranes, either alone or in the presence of leukocytes. METHODS Semen samples from normozoospermic donors were prepared by density gradient. The sperms were exposed to ...
متن کاملEffect of manganese on bovine sperm motility, viability, and lipid peroxidation in vitro
Manganese (Mn) is a chain-breaking antioxidant in biological systems. The objective of the present study was to determine the optimal dose of Mn to reverse free radical-mediated oxidative damage on motility, viability, and lipid peroxidation (LPO) of sperm from five bulls (local crossbred cattle). Fresh semen was suspended in 2.9% sodium citrate, divided into equal fractions, and subjected to M...
متن کاملLipid Peroxidation and Nitric Oxide Levels in Male Smokers' Spermatozoa and their Relation with Sperm Motility
BACKGROUND Nitric oxide (NO) is synthesized from L-arginine by a family of enzymes known as nitric oxide synthases. Low concentrations of NO is essential in biology and physiology of spermatozoa, but high amounts of NO is toxic and has negative effects on sperm functions. Moreover, sperm membrane contains high concentrations of polyunsaturated fatty acids that are highly susceptible to oxidativ...
متن کاملEffects of Adding Sodium Nitroprusside to Semen Diluents on Motility, Viability and Lipid Peroxidation of Sperm in Holstein Bulls
Background Nitric oxide (NO) that plays important role in all sexual activities of animals is made from the amino acid L-arginine by the enzymatic action of NO synthase (NOS). NO makes a band with sulfur-iron complexes, but due to production of steroid sexual hormones related to the enzymes involved in this complex, NO can change the activity of these enzymes. NO affects many cells including ve...
