“…Lipid peroxidation of plasma membrane increases after freezing and thawing, which results in metabolic changes as well as loss of motility, membrane integrity and fertilizing capability of spermatozoa (Agarwal and Prabakaran, 2005). As DO was found to be responsible for ROS production and subsequently lipid peroxidation (Kumar et al, 2018), partial deoxygenation of semen extender reduced lipid peroxidation during semen cryopreservation which was indicated by lesser MDA production at the post-thaw stage in the present study (Fig 2). It was more pronounced in 4 ppm group compared to other treatment groups at this stage.…”

“…The lowest TAC value observed in the control group at the post-thaw stage might be due to greater utilisation of available antioxidants to scavenge the free radicals generated. Higher TAC concentrations in treatment groups possibly indicated lesser free-radical formation due to suppressed oxidative metabolism at lower DO concentrations (Kumar et al, 2018).…”

“…Several factors had been proposed to explain the cryo‐damage to human spermatozoa such as cold shock, osmotic stress and oxidative stress (OS; Amidi, Pazhohan, Shabani, Khodarahmian, & Nekoonam, 2016). The post‐thaw sperm quality is critically affected by the OS status that accompanies the cryopreservation process (Bucak et al, 2010; Kumar et al, 2018).…”

“…It is suggested that the cryopreservation procedure carried out under reduced oxygen tension may improve the post‐thaw semen quality. To achieve low O 2 tension, liquid nitrogen flushing, mechanical removal of oxygen by using negative pressure, and vigorous gassing with 100% nitrogen gas have been used to deoxygenate the extended semen (Balamurugan et al, 2018; Kumar et al, 2018; Pande et al, 2015). In the food industry and antibiotic testing, a commercially available Escherichia coli membrane preparation (Oxyrase) is used in creating an artificial anaerobic environment (Jacobson, Thunberg, Johnson, Hammack, & Andrews, 2004; Spangler & Appelbaum, 1993; Spangler, Jacobs, & Appelbaum, 1995).…”
