Background: Oxidative stress occurs when the oxidative homeostasis is damage. Excessive ROS are generated and this reaction has been proposed to produce marked damage to the structure and function of sperm. Materials and Methods: This study was designed to investigate the protective effects of of American Ginseng against cyclophosphamide - induced damage in the rat sperm. For this experiment, t...

The study of chromatin constitutes one of the most active research fields in life sciences, being subject to constant revisions that continuously redefine the state of the art in its knowledge. As every other rapidly changing field, chromatin biology requires clear and straightforward educational strategies able to efficiently translate such a vast body of knowledge to the classroom. With this ...

OBJECTIVE The aim of the present study was to examine the relationship among male age, strict morphology, and sperm chromatin structure and condensation. METHODS Sperm samples from a total of 100 men underwent semen analysis, and sperm chromatin structure and condensation were assessed with toluidine blue (TB) and aniline blue (AB) tests. RESULTS Prevalence of strict morphology of less than...
