Spontaneous lipid peroxidation and production of hydrogen peroxide and superoxide in human spermatozoa. Superoxide dismutase as major enzyme protectant against oxygen toxicity
Human spermatozoa liquid peroxidation superoxide production hydrogen peroxide production
2009/2/23
Spontaneous lipid peroxidation in washed human spermatozoa was induced by aerobic incubation at 32 C and measured by malonaldehyde production; loss of motility during the incubation was determined s...
Lipid peroxidation and human sperm motility: protective role of vitamin E
Asthenospermia lipid peroxidation vitamin E human spermatozoa
2009/2/16
Asthenospermia is the main factor of male infertility among patients consulting the Asir Infertility Center in Abha, Saudi Arabia. Lipid peroxidation occurring in both the seminal plasma and sperm...
Effect of sperm lipid peroxidation on fertilization
Spermatozoa sperm hyperactivation zona pellucida sperm capacitation reactive oxygen species
2009/2/16
This study was aimed at determining, with homologous mouse gametes, whether a level of membrane lipid peroxidation insufficient to affect sperm motility parameters can alter sperm fertilizing pote...
Lipid peroxidation and antioxidant enzyme activities in the rat testis after cigarette smoke inhalation or administration of polychlorinated biphenyls or polychlorinated naphthalenes
Reactive oxygen oxidative stress superoxide dismutase catalase cigarette smoking environmental chemicals
2009/2/12
Lipid peroxidation products and antioxidant enzyme activities were studied in the rat testis following exposures to cigarette smoke, polychlorinated biphenyls (PCBs), or polychlorinated naphthalen...
Correlation between the rate of lipid peroxidation and cellular maturity as measured by creatine kinase activity in human spermatozoa
Spermatogenesis sperm development oligospermia male fertility
2009/2/12
We have demonstrated previously that creatine kinase (CK) activity is a measure of cellular maturity and fertilizing potential in human spermatozoa. In the present work we have examined whether th...
Comparison of effects of 0.5 and 3.0 Gy X-irradiation on lipid peroxidation and antioxidant enzyme function in rat testis and liver
0.5 and 3.0 Gy X-irradiation lipid peroxidation antioxidant enzyme function rat testis
2009/2/12
The prooxidant effect of X-irradiation on rat testis and liver tissue was studied with doses of 0.5 and 3.0 Gy; the latter dose kills the proliferating spermatogonia and causes a maturation-depletio...
Evidence that membrane stress contributes more than lipid peroxidation to sublethal cryodamage in cryopreserved human sperm: glycerol and other polyols as sole cryoprotectant
Human sperm cryopreservation cryoprotectant sublethal cryodamage lipid peroxidation membrane stress
2009/2/12
One effect of cryopreservation on human sperm is sublethal cryodamage, in which cell viability post-thaw is lost more rapidly at later times than in fresh cells. We hypothesized two modes of suble...
The effect of reactive oxygen species on equine sperm motility, viability, acrosomal integrity, mitochondrial membrane potential, and membrane lipid peroxidation
reactive oxygen species equine sperm motility viability
2008/12/25
The objective of this study was to examine the influence of reactive oxygen species (ROS), generated through the use of the xanthine (X)-xanthine oxidase (XO) system, on equine sperm motility, via...
Trisialoganglioside GT1b Prevents Increase in Sperm Membrane Molecular Ordering Induced by In Vitro Lipid Peroxidation
Membrane rigidity gangliosides spermatozoa
2008/12/23
The effect of various types of gangliosides, the sialic acid-containing glycosphingolipids, on human sperm membrane during lipid peroxidation induced by Fe2+/ascorbate ions was investigated. The m...
