Lipid 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 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 کاملP-63: The Effect of Temperatures on Goat Epididymal Sperm Motility in Tissue Culture Media 199
Background: There is a general deterioration in sperm quality depending on time postmortem. Refrigeration of the epididymes down to around 5°C is the best strategy to lower this damage and there are many dissim ilarities between species, possibly due to differences on cold shock endurance of epididymal sperm. Our objective was to determine the effect of 5°C and 37°C on goat epididymal sperms mo...
متن کاملP-70: Effect of Xylose on Epididymal Sperm Motility in Water Buffalo (Bubalus bubalis)
Background: In mammalian spermatozoa, motility is one of the most important parameters for evaluating the quality of the semen. From a functional point of view, motility is strongly related to the spermatozoa’s ability to manage its energy status, Thus, modulation of energy status could be translated into significant changes in motility patterns. The aim of the present study was to evaluate xyl...
متن کاملSperm characteristics in Grass carp, Ctenopharyngodon idella effect of ions on spermatozoa motility and fertilization capacity
In this study, sperm characteristics (motility parameters and ionic composition of seminal plasma) and effect of ions on motility (duration of motility of sperm and percentage of motile spermatozoa) and fertilization capacity (fertilization rate, hatching rate, survival rate and larvae length) were investigated in Ctenopharyngdon idella. The longest duration of motility obtained in solution con...
