background: para-nonylphenol (p-np) is able to induce malformations in male reproductive system. objective: the aim of this study was to investigate the preventing role of vitamin e (vit.e) on sperm parameters and reproductive hormones in developing rats. materials and methods: pregnant rats were divided into 4 groups: control p-np vit.e and p-np+vit.e. treatments were performed on day 7 of ges...

background: the role of oxidative stress in endosulfan-induced reproductive toxicity has been implicated. this study was performed to evaluate the possible protective effect of vitamins e and c, against endosulfan-induced reproductive toxicity in rats. methods: fifty adult male sprague–dawley rats were randomly divided into five groups (n=10 each). the groups included a control receiving vehicl...

background: para-nonylphenol (p-np) is one of the environmental pollutants which cause reproductive system disorders. objective: the effects of vitamin e on ovary structure during its development in rats treated with p-np. materials and methods: 32 wistar female rats after mating were divided into 4 groups; control vitamin e (100mg/kg/day) p-np (250mg/kg/day) and p-np + vitamin e. the rats were...

Background: This study was undertaken to investigate whether treatment with vitamin E and N acetyl cystein protects rat sperm by inhibiting reactive oxygen species generation induced by lead (Pb) exposure. Materials and Methods: After an acclimatization period of one week, 20 Male rats were divided into 4 groups of 5 rats each. Animals within different treatment groups were maintained on their ...

background: nano-particles are extensively employed in most industries. several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. however, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices. objective: investigation of the effects of silver nano-part...

Background Nonyl phenol (NP) is a degradation product of nonylphenol polyethoxylates, which are widely used in the production of industrial and consumer surfactants. NP a Kind of environmental chemical, is thought to imitate endogenous hormones, inhibit the actions of hormones, and induce reproductive abnormalities. In this study, evaluation of Nonyl phenol toxic effects on reproductive system ...

Background: Formaldehyde (FA) is a suspected reproductive toxicant, which may cause significant adverse effects on human reproductive system. Given to its widespread use in occupational setting, and more recently, in several industries related to construction and household products, everyone may be exposed to FA. This study was designed to determine the effect of FA and to investigate possible ...
