Motility parameters were quantified pre\u2010 and postcryopreservation using computer\u2010assisted semen analysis (CASA) with vapor\u2010phase liquid nitrogen protocols. Data\u2010independent acquisition (DIA) quantitative proteomics, combined with LC\u2013MS\/MS, was used to profile global protein expression changes. Differential protein analysis was performed using multibioinformatics tools for functional annotation and network modeling. Papanicolaou and acridine orange (AO) staining were used to assess sperm morphology and DNA integrity, while reactive oxygen species (ROS) assay and immunofluorescence were employed to validate the proteomic analysis results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We identified 512 differentially expressed proteins (32 upregulated, 480 downregulated), which are predominantly enriched in pathways related to metabolic reprogramming, oxidative stress response, and protein homeostasis. Immunofluorescence staining further confirmed markedly reduced levels of SOD1, PGK2, PKC\u2011alpha, and phospho\u2011tyrosine in sperm after freeze\u2013thaw cycling. These molecular hubs are associated with sperm motility and functional stability and may be essential for regulating energy metabolism, oxidative balance, and proteotoxicity during cryopreservation\u2010induced stress in rhesus macaque sperm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Cryopreservation induces profound proteomic remodeling in rhesus macaque sperm, mitochondrial electron transport, and metabolic homeostasis.
