Comparative Aspects of Lipid Peroxidation and Antioxidant Protection in Avian Semen

Gallic acid supplementation partially ameliorates reproductive aging in rooster breeders by improving semen quality, sperm kinetics, hormones, and antioxidant status

“…However, improvements took 8 to 10 wk with apple pomace ( Akhlaghi et al, 2014b ) or dried ginger powder ( Akhlaghi et al, 2014a ), potentially reflecting differences in bioactive dosage. While higher sperm lipid content benefits quality ( Surai et al, 2003 ), excess polyunsaturation also increases susceptibility to peroxidative damage from reactive oxygen species ( ROS ) ( Kelso et al, 1997 ). Through mechanisms including induced membrane lipid peroxidation and apoptosis, ROS exposure has been frequently associated with reduced semen concentration, sperm motility, viability and morphology ( Suleiman et al, 1996 ; Surai et al, 2001 ; Agarwal et al, 2014 ).…”

Influence of Climatic Variables on Corporal Attributes of Adult Female Caiman and Their Relationship with Reproductive Success

“…1). This relationship might be due to the fact that females with better (higher) body condition could mobilize and invest quality reserves (such as PUFA) that affect reproduction, mainly by transferring them to eggs, because PUFA is essential for embryonic development (Speake and Thompson, 1999; Speake et al, 2004). Although the muscle is not primarily a reserve tissue, there is evidence that during vitellogenesis in reptiles the inversion of energy may be endogenous, whereby there is mobilization of adipose (fat body) and muscular tissue reserves (Warner et al, 2008); therefore, these values could indicate that these FA have been mobilized from the reserves to be invested in reproduction (Price, 2016).…”

“…To evaluate physiological condition, we select unsaturated FA, mainly essential FA (EFA), because they best reflect the FA composition of the diet and/or food resources of animals and may allow us to assess the possible energy investment in reproduction (Speake et al, 1999; Labaque et al, 2013; Leiva et al, 2021).…”

Germinated Wheat as a Potential Natural Source of Antioxidants to Improve Sperm Quality: A Canary Trial

“…Antioxidant substances play an essential role in preventing oxidative stress [ 70 ]. It was reported that these substances are necessary for sperm membrane integrity, motility, and fertilizing ability [ 71 ].…”
