NAD + is also involved in metabolic switching, or the Warburg effect, in which the main source of energy production is anaerobic glycolysis through fermentation of pyruvate to lactic acid, as opposed to mitochondrial oxidative phosphorylation 340
It is typically studied in longevity and age-related signaling models, where researchers examine endpoints such as gene expression patterns, cellular stress responses, and telomere-related pathways in preclinical or in vitro systems
When extracellular Zinc(II) binds to this receptor, it triggers an intracellular signalling pathway that ultimately results in increased sperm motility and acrosomal exocytosis [16]

Future studies should investigate the mechanisms by which heat stress impairs male fertility, expand the use of human clinical samples, and integrate proteomic and multiomics approaches
