Short-term testicular ischemia was induced unilaterally by ligating the testicular artery for 60 or 100 minutes in adult rats. After 7 days, the rats were fixed by vascular perfusion. The effect of ...
The motility and velocity of bovine spermatozoa incubated in TCM-199 are reduced in comparison with those incubated in a simpler media made for sperm, such as modified Tyrode (Sp-Talp). Moreover, ...
Reactive oxygen species (ROS) have been shown to impair sperm function. The actions of ROS are reduced by antioxidant enzymes, including catalase. Although catalase-like activity has been demonstrated...
We have examined in mouse testis the steady-state levels of mRNAs encoding glutathione peroxidase (GSHPx), catalase (CAT), and superoxide dismutase 2 (SOD-2), three enzymes essential for the antio...
Reactive oxygen species, as hydrogen peroxide, can be damaging to sperm. Most species have little protective catalase in their semen, but rabbit semen contains substantial amounts of catalase. The...
In the present study the potential benefit of reactive oxygen species (ROS)-scavenging enzymes superoxide dismutase (SOD) and catalase (CAT) when cryopreserving boar spermatozoa was evaluated. Poole...
