Effects of astaxanthin supplementation on the sperm quality and antioxidant capacity of ram semen during liquid storage

Effect of astaxanthin on the quality of boar sperm stored at 17°C, incubated at 37°C or under in vitro conditions

“…In our study, ASX addition positively affected total and progressive motility, while the same beneficial effect of ASX on total motility was evident during 1 hr of sperm incubation at 37°C and under in vitro conditions. In accordance with our results, ASX supplementation to bull and ram semen significantly increased the values of total and progressive motility (Fang et al., ; Farzan et al., ). Comhaire et al.…”

“…Many studies reported that ASX is a promising antioxidant providing important biological properties, such as anti‐inflammatory and anticancer actions (Ambati, Phang, Ravi, & Aswathanarayana, ). Also, ASX improved sperm parameters and fertility in human (Comhaire, El Garem, Mahmoud, Eertmans, & Schoonjans, ), ram (Fang et al., ) and bull (Farzan, Chamani, & Varnaseri, ). Nevertheless, the effect of ASX on boar semen has not been investigated, yet.…”

Effect of Astaxanthin Supplementation on Semen (Karan Fries Bulls) Storage at 5 °C

“…The lower level of CAT and SOD concentration in extended semen also indicates the antioxidant activity of AX. Similarly, Fang et al, (2015) and Farzan et al, (2014) also reported the improvement of …”

“…The supplementation of AX @ 2 and 4 µM shown to increase sperm vitality and plasma (Fang et al, 2015). Malondialdehyde (product of lipid peroxidation) and reactive oxygen species (ROS) levels also decreased (p≤0.05) markedly during 72 hrs of storage at 5 °C (Fang et al, 2015). Sperm membrane is prone to free radical attack due to the high content of phospholipids (Almbro et al, 2011).…”

“…AX is more powerful antioxidant than beta-carotene and lutein (O"Connor and O"Brien, 1998) enhancing antibody production (Jyonouchi et al, 1994) as well as boosts mitochondrial activity (Wolf et al, 2010). The supplementation of AX @ 2 and 4 µM shown to increase sperm vitality and plasma (Fang et al, 2015). Malondialdehyde (product of lipid peroxidation) and reactive oxygen species (ROS) levels also decreased (p≤0.05) markedly during 72 hrs of storage at 5 °C (Fang et al, 2015).…”
