BACKGROUND Stress is a cause of male infertility. Although sex hormones and sperm quality have been shown to be low in stress, sperm physiology and testicular functional proteins, such as phosphotyrosine proteins, have not been documented. OBJECTIVE To investigate the acrosome status and alterations of testicular proteins involved in spermatogenesis and testosterone synthesis in chronic stres...

PURPOSE The aim of this study was to evaluate the potential genotoxicity induced by chronic oral exposure to depleted uranium (DU). MATERIALS AND METHODS Weanling Wistar rats (F(0)), 50/sex/group, were exposed to DU in food at doses of 0, 4, or 40 mg kg(-1)day(-1) for four months. They were subsequently mated, resulting in the birth of F(1) rats. Fifty F(l) weanlings/sex/group were exposed fo...

objective: to determine bilateral effects of unilateral iatrogenic vas deferens trauma (uit) on epididymal sperm characteristics and in vitro fertilizing capacity in an experimental mouse model. methods: experiments were performed on three equal groups each comprising six adult male mice. following anaesthesia, uit was induced by clamping left vas deferens with a mosquito clamp in fully locked ...

background: stanozolol (st) is a synthetic anabolic-androgenic steroid often abused by athletes. an increasing body of evidence points towards the role of st misuses in the pathogenesis of a wide range of adverse effects including reprotoxicity. objective: the aim of this study was to analyze the possible reproprotective effect of royal jelly (rj) as an efficient antioxidant in st-treated mice....

Background: cyclophosphamide is anticancer agent that has been toxic effects on male reproductive system.The antioxidant agents in imedeen such as lycophence GS and Biomarine complex play important role in preventing the direct and indirect effects of free radicals caused by CP; therefore, the purpose of this study was to evaluate the effects of Imedeen on sperm characteristics of mature male m...

Background: Glyphosate (GPT) is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf and grasses known to compete with commercial crops grown around the globe. According to United States environmental protection agency the chemical has been reported as a third class toxin. Present study was designed in order to evaluate GPT-induced detrimental effects on testicula...

background: the most common chromosomal abnormality due to non-obstructive azoospermia (noa) is klinefelter syndrome (ks) which occurs in 1-1.72 out of 500-1000 male infants. the probability of retrieving sperm as the outcome could be asymmetrically different between patients with and without ks, therefore logistic regression analysis is not a well-qualified test for this type of data. this stu...

Dietary lipids may affect sperm membrane structure, fluidity and its susceptibility to oxidative phenomena which may lead to altered sperm viability and proper binding to eggs. Given the recently demonstrated beneficial effects of fish oil diets on turkey fertility and embryo viability, the aim of this study was to test a caviar-derived marine product on spermatogenesis and sperm quality. Sixty...

Case Report To date, several studies of aneuploidy rate in spermatozoa from infertile men have been published. Most of them found an increase incidence of aneuploid spermatozoa in infertile patients compared with normal donors (Moosani et al, 1995; Finkelstein et al, 1998; McInnes et al, 1998; Pang et al, 1999; Rives et al, 1999; Vegetti et al, 2000). However, in other studies, no differences i...

In this data article, 146 villagers (exposed group) were randomly selected from the workers who involved in the e-wastes recycling directly as a daily job in Tianjin. Control group, including 121 villagers, came from another town without e-waste disposal sites. Chromosomal aberrations (CA) and cytokinesis blocking micronucleus (CBMN) were performed to detect the cytogenetic effect for each subj...
