background:   objective: the aim of this study was to investigate the harmful effects of sodium arsenite on sperm parameters and the antioxidant effects of vit.e on sperm anomalies in sodium arsenite treated rats.   materials and methods: adult male rats were divided into 4 groups: control, sodium arsenite (8 mg/kg/day), vit.e (100 mg/kg/day) and sodium arsenite+vit.e. oral treatments were perf...

background: sodium arsenite can impair male reproductive function by inducing oxidative stress. silymarin is known as a potent antioxidant.objective: this study was performed to investigate if silymarin can prevent the adverse effect of sodium arsenite on ram sperm viability, motility and mitochondrial membrane potential.materials and methods: epidydimal spermatozoa obtained from ram were divid...

Background: Arsenic as a heavy metal exerts malformation and changes in the reproductive system of men via induction of oxidative stress. We sought to investigate the impact of Vitamin C (Vit C), as a potent antioxidant, on sperm quality and testicular tissue in mice that received sodium arsenite. Methods and materials: NMRI mice were classified into four groups: control, sodium arsenite (7 mg...

Background & Aims: Sodium arsenite causes oxidative stress and endocrine disorders in the reproductive system. The aim was to investigate the protective role of curcumin as an antioxidant on the seminal vesicle tissue in adult mice treated with sodium arsenite. Materials & Methods: Adult male Naval Medical Research Institute (NMRI) mice were randomly divided into 5 groups (six mice per group) ...

Background & Aims: Sodium arsenite, an environmental pollutant, produces free radicals with harmful effects on the reproductive system. The aim of this study was to investigate the effect of curcumin, as a strong antioxidant, on the testis tissue and spermatogenic cell population in mice treated with sodium arsenite. Methods: In this experimental study, A...

background: sodium arsenite and/ or vasectomy may cause variation in sex hormones which affect pathophysiology of reproductive organs. objective: the aim was to investigate the morphological changes in structure of testis and hormonal imbalance in bilateral vasectomised rats treated with sodium arsenite. materials and methods: four groups of rats: bilateral vasectomy + sodium arsenite, bilatera...

Arsenite-induced mitotic abnormalities result in mitotic death in several cancer cell lines. However, how arsenite induces these effects is not known. We have previously shown that arsenite induces mitotic arrest, mitotic abnormalities, and mitotic death in CGL-2 cells. To further delineate the mechanism of action of arsenite, we examined its effect on centrosome duplication and the possible li...

background: exposure to arsenic is associated with impairment of male reproductive function by inducing oxidative stress. silymarin with an antioxidant property scavenges free radicals. objective: the aim of this study was to investigate if silymarin can prevent the adverse effects of sodium arsenite on ram sperm plasma membrane and acrosome integrity. materials and methods: ram epidydimal sper...
