Study of the membrane lipid composition of Atlantic salmon (Salmo salar ) spermatozoa and its relation with semen quality

Oxidative stress and use of antioxidants in fish semen cryopreservation

“…Fish spermatozoa are characterised by presenting a high content of saturated and unsaturated fatty acids, the latter being either dipolyunsaturated fatty acids (diPUFAs), orespeciallypolyunsaturated fatty acids (PUFAs) (Bell et al 1997;Butts et al 2011;Mansour et al 2011;Díaz et al 2018). In the majority of species, including fish, PUFA profiles are higher in spermatozoa than in somatic cells (Labbé & Maisse 1996;Vernet et al 2004;Klaiwattana et al 2016;Dadras et al 2017).…”

“…ion channels), endocytosis, exocytosis, motility and resistance to osmotic shock (Samaee et al 2019). In this context, fatty acid profiles have been studied in spermatozoa of some fish species in order to establish new biomarkers of sperm quality and cryoresistance (Mansour et al 2011;Horokhovatskyi et al 2016;Klaiwattana et al 2016;Díaz et al 2018). Although those studies have taken different approaches, and not all the parameters were assessed in any single study, their results indicate that there is a tendency for spermatozoa with a high content of PUFAs and low content of saturated and monounsaturated fatty acids to give better results in terms of fresh/post-thaw sperm motility and fertility.…”
