objective: although key roles for dietary vitamin e (vite) and fatty acid (fa) in fertility have been confirmed, limited data are available on the effects of vite alone, or a constant level of vite supplemented by dietary omega-6 and omega-3 fas in combination on male reproduction. consequently in this paper, the effects of vite, sunflower oil, fish oil and their combination on rat sperm were i...

The aims of this study were to investigate the adverse effects of sodium arsenite on the reproductive system of male rats as well as to examine whether vitamin E is able to ameliorate these effects. Adult rats were divided into four groups: 1/ control, 2/ sodium arsenite (8 mg/kg/day), 3/ vitamin E (100 mg/kg/day), and 4/ sodium arsenite +vitamin E group. Treatments were administered orally by ...

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: Spermatogenesis is a necessary process in fertility and reproductive capacity of humans. In view of the relative high prevalence of spermatogenesis disorders in men and the failure of treatments provided in conventional medicine, new therapeutic approaches are being considered. This study will be designed to investigate the effect of Ceratonia siliqua (Carob) syrup and vitamin E on ...

OBJECTIVE To examine the association between low serum vitamin D concentration and estimates of male reproductive function. DESIGN Cross-sectional study. SETTING University hospital. PATIENT(S) From a Danish pregnancy cohort established in 1984-1987, 347 sons were selected for a study conducted in 2005-2006. INTERVENTION(S) Semen parameters and reproductive hormones were related to vita...

Background: Cadmium is a potential pollutant of the environment. It manifests cyto-toxic effects in different organs in animals. In the testis, changes due to disruption of the blood-testis barrier and oxidative stress have been noted. Therefore, the present study was carried out to investigate the potential protective effects of vitamin E and green tea extract in combination against cadmium (C...

Background: Animal models and observational studies have suggested a favorable role of vitamin D in male reproduction. However, randomized clinical trials investigating the effect of vitamin D supplementation on male fertility are limited. Therefore, this study aimed to examine the effect of vitamin D supplementation on semen quality, reproductive hormones, and anthropometric measurements in vi...

Background: Vitamin E is believed to be the primary component of the antioxidant system in spermatozoa. There is a relationship between activity of these antioxidant and function of sperm. Vitamins E and C which are belong to non-enzymatic antioxidant are used as a supplemented drug to improve sperm quality and male fertility. The present study was carried out to investigate the positive effect...
