Varicocele-associated decrease in antioxidant defenses
Varicocele oxidative stress total reactive antioxidant
2009/2/18
Varicocele is associated with an oxidative stress condition. We have measured the antioxidant defenses of varicocele patients both at the local (seminal plasma) and systemic (blood plasma) levels. T...
Antioxidant potential of human serum albumin：role in the recovery of high quality human spermatozoa for assisted reproductive technology
Percoll Cypridina luciferin analog MCLA superoxide
2009/2/17
Human serum albumin (HSA) is being considered as an alternate media for sperm enrichment in assisted reproductive technology (ART) because of recent concern with the use of Percoll. In this study,...
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...
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...

Developmental profiles of the activity of the antioxidant enzymes superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH-Px), glutathione transferase (GSH-Tr), and hexose monophosphate ...
Impaired seminal antioxidant capacity in human semen with hyperviscosity or oligoasthenozoospermia
Superoxide dismutase catalase total antioxidant status
2008/12/29
Antioxidant capacity of seminal plasma was evaluated in 120 semen samples subdivided into asthenozoospermic and oligoasthenozoospermic specimens with normal consistency and into asthenozoospermic an...
Quantification of the nonenzymatic fast and slow TRAP in a postaddition assay in human seminal plasma and the antioxidant contributions of various seminal compounds
Quantification nonenzymatic fast and slow TRAP postaddition assay human seminal plasma seminal compounds
2008/12/25
Total radical-trapping antioxidant potential (TRAP) measurements of human seminal plasma (N = 25) were performed by using a post-addition assay based on trapping 2,2' Azino-bis(3-ethylbenzthiazoline...
Spermatozoa Have Decreased Antioxidant Enzymatic Capacity and Increased Reactive Oxygen Species Production During Aging in the Brown Norway Rat
Oxidative stress epididymis glutathione peroxidase superoxide dismutase reproduction sperm
2008/12/24
As the proportion of aged males attempting to reproduce continues to rise, so does the concern regarding the quality of spermatozoa from aged men. An imbalance between the generation of reacti...
Effect of Antioxidant Intake on Sperm Chromatin Stability in Healthy Nonsmoking Men

2008/12/23
Oxidative stress is detrimental to sperm function and a significant factor in the etiology of male infertility. This report examines the association between dietary and supplementary intake of the...
Reduction of the Incidence of Sperm DNA Fragmentation by Oral Antioxidant Treatment
Sperm DNA damage ejaculated spermatozoa TUNEL assay in vivo treatment vitamin C
2008/12/23
Sperm DNA fragmentation is known to compromise male fertility. Previous findings have suggested the implication of oxidative stress in the etiology of this pathological condition. The present study wa...
Oxidative Stress and Antioxidant Therapy：Their Impact in Diabetes-Associated Erectile Dysfunction
