Morphologic changes induced by short-term ischemia in the rat testis are not affected by treatment with superoxide dismutase and catalase
short-term ischemia rat testis superoxide dismutase and catalase
2009/2/23
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 ...
Catalase and oviductal fluid reverse the decreased motility of bovine sperm in culture medium containing specific amino acids
Hydrogen peroxide oviduct secretions toxicity

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, ...
Catalase mRNA expression in the male rat reproductive tract
Catalase mRNA expression male rat
2009/2/16
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...
Developmental expression of glutathione peroxidase, catalase, and manganese superoxide dismutase mRNAs during spermatogenesis in the mouse
Antioxidant enzymes gene expression testis translational regulation
2009/2/16
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...
High catalase content of rabbit semen appears to be inherited
High catalase rabbit semen inherited
2008/12/25
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...
Survival and In Vitro Fertility of Boar Spermatozoa Frozen in the Presence of Superoxide Dismutase and/or Catalase
Antioxidants cryopreservation sperm porcine
2008/12/22
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...
