The kinetic changes in FA levels in sperm were detected using gas chromatography\u2010mass spectrometry. The mitochondrial activity of sperm thawed in media containing LM or FAs was analyzed based on the fluorescence intensity of JC\u20101 staining and the oxygen consumption rate. FA transporters were observed using whole\u2010mounted immunofluorescence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Sperm linear motility was significantly (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.05) increased after thawing in media with LM and FA. Moreover, saturated fatty acids were predominant in sperm thawed in media with LM. Notably, our study revealed that frozen bovine sperm possessed FA transporters in the midpiece where the fluorescence signals were detected after treatment with fluorescence\u2010tagged FA. Treatment with FA activated electron transport in mitochondria through \u03b2\u2010oxidation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Sperm linear motility is facilitated by FAs in the thawing media used for frozen bovine sperm.
