Processing for artificial insemination (AI) stresses boar sperm by osmotic effects; altering cell size, shape and membranes; intracellular ice formation; and production of reactive oxygen species (ROS). Sperm response to ROS is concentration\u2010dependent, with low levels activating the ERK pathway to stimulate tyrosine phosphorylation (Tyr\u2010P) and capacitation, but high concentrations or inappropriately timed onset of ROS pathways can harm sperm. Fresh boar sperm exposed to ROS increased intracellular hydrogen peroxide (H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>) phospholipase and lipid peroxidation, maintained viability but lost motility and underwent acrosome reactions (AR).
