Catalase and Uric Acid Prevent Morphological Damage to the Sperm Flagella of During 96 Hours at Low Storage Temperatures.

Oxidative stress is one of the main causes of loss of sperm function during chilled storage. The aim of the current study was to evaluate the effects of a fructose-based extender, which was supplemented with catalase or uric acid, on the motility, viability, morphological integrity, and lipid peroxidation (LPO) of spermatozoa. Sperm was diluted in extenders containing catalase (0; 0.
