an important part of male infertility of unknown etiology may be attributed to various environmental and occupational exposures to toxic substances, such as lead. the reproductive effects of lead are complex and appear to involve multiple pathways, not all of which are fully understood. it is still unclear, for example, if male reproductive issues in lead-exposed persons are mostly related to t...

objective(s): the adverse effects of pyridaben on reproductive system in male animals are not well established. this study was designed to elucidate how pyridaben can effects the histomorphometric, hormonal alternations and reproductive functions of balb/c mice .   materials and methods : for this study, 80 adult and apparently healthy male balb/c mice were divided into three groups viz, contro...

background: diminished libido and sexual dysfunction are unusually common among male epileptic patients. the most important etiologic factor may be antiepileptic drugs (aeds)-induced androgen deficiency. we compared reproductive hormone levels among men with epilepsy taking various aeds and normal controls. methods: subjects were 59 male epileptic patients who aged 24 ± 5 years. they had been r...

results genotype frequencies of g/a in fertile and infertile men were significantly different (χ2 = 4.16, df = 1, p = 0.041). genotype frequencies of g/g and a/ain fertile and infertile men were not significantly different (χ2 = 3.32, df = 1, p = 0.068 and χ2 = 0.521, df = 1, p = 0.47, respectively). the risk of infertility was 1.43 folds higher in individuals with the a/a genotype compared to ...
