Ameliorative effect of chitosan nanoparticles in capacitation media on post-thawing in vitro fertilizing ability of bovine spermatozoa.

This study aimed to investigate the effect of supplementation of chitosan nanoparticles (CSNPs) on the capacitation of bovine spermatozoa during the in vitro fertilization process. Hyperactivated motility (HAM) and acrosome reaction (AR) of sperm cells as well as in vitro fertilization and cleavage rates are the main parameters used to estimate the effect of CSNPs on bovine spermatozoa's fertilizing ability. In this study, three different concentrations of CSNPs (10, 20 and 100 μg/mL) were prepared and characterized.

Protective effects of selenium and nano-selenium on bisphenol-induced reproductive toxicity in male rats.

Bisphenol A (BPA) is a widespread compound associated with the manufacture of many consumer products. The BPA-induced reproductive toxicity was reported to be mainly attributed to oxidative stress. However, the role of antioxidants usage to decrease the injurious effects of BPA, on male reproductive functions, remains to unveil.

Protective effect of Chitosan nanoparticles against the inhibitory effect of linoleic acid supplementation on maturation and developmental competence of bovine oocytes.

The current study was conducted to investigate the effect of linoleic acid-treated oocytes during in vitro maturation (IVM) on cumulus cell expansion, oocyte nuclear maturation, blastocyst development and DNA damage of cumulus cells and how its effects were alleviated by supplementation of the maturation medium with Chitosan nanoparticles (CSNPs). Inhibitory effects of LA at a concentration (100 μM/ml) or more significantly decreased the percentage of oocytes reaching metaphase II stage, the rate of fully expanded cumulus cells 24 h after IVM and the percentage of blastocyst rate compared with the control (p < 0.05).

Role of ginger against the reproductive toxicity of aluminium chloride in albino male rats.

The aim of the current study was to evaluate reproductive disorders concomitant with aluminium chloride (AlCl(3) ) toxicity in Albino male rats. Attention was also directed to study the protective influence of ginger against this toxicity. Forty-five mature Albino Wistar male rats were equally divided into three groups; the first group was served as control group while those of the second group (AlCl(3) ) were daily treated with 34 mg/kg bw.
