Evaluation of antioxidant enzymes in the female genital fluid of the bat Corynorhinus mexicanus during sperm storage

Abstract Female Corynorhinus mexicanus bats store sperm for three months. One cause of the death is action reactive oxygen species (ROS). Three antioxidant enzymes – superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) regulate REDOX state environment in which gametes are stored. The aim this study was to evaluate enzymatic activity female genital fluid during period storage (October-December). bats’ determined by spectrophotometry. SOD 20 USOD/ml/min each month. Total GPX 70 UGPX/ml/min October, but increased November and December 145 UGPX/ml/min. Specific CAT 2000 UK/ml/min it 16 000 UK/ml/min, then 32 December. ROS fluorescence indices ranged from 3000 8000 with no significant differences. These data show that participate maintenance viability reproductive tract C. .
