The levels of homocysteine and vitamin B\n                    <jats:sub>6<\/jats:sub>\n                    were measured in 108 asthenozoospermic and 64 normozoospermic semen samples. Homocysteine levels in seminal plasma were determined using high\u2010performance liquid chromatography, whereas vitamin B\n                    <jats:sub>6<\/jats:sub>\n                    levels were measured by liquid chromatography\u2010tandem mass spectrometry. The results showed that seminal plasma levels of homocysteine were significantly higher in the asthenozoospermic group than in the normozoospermic group (3.08 \u00b1 0.320 vs. 1.23 \u00b1 0.320\n                    <jats:italic>\u2009\u03bc<\/jats:italic>\n                    mol\/L,\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.0001). Notably, the receiver operating characteristic (ROC) curve analysis demonstrated that the area under the curve was 0.999 (\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.0001), indicating a strong diagnostic performance of seminal plasma homocysteine in distinguishing asthenozoospermic men from normozoospermic men. In addition, the cutoff value was &gt;\u20091.87\u2009\n                    <jats:italic>\u03bc<\/jats:italic>\n                    mol\/L, with a specificity of 100.0% (95% CI: 94.3%\u2013100%) and a sensitivity of 99.1% (95% CI: 94.9%\u201399.9%). In the normozoospermic group, there was no statistically significant association between seminal plasma levels of homocysteine and progressive motility (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.675,\n                    <jats:italic>r<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.00286) or total motility (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.178,\n                    <jats:italic>r<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.0291) of spermatozoa. However, in the asthenozoospermic group, progressive and total motility were inversely correlated with the seminal plasma levels of homocysteine (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.0025,\n                    <jats:italic>r<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.0827,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.0048,\n                    <jats:italic>r<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.0725, respectively). No significant correlation was found between homocysteine levels and sperm concentration, semen volume, age, or seminal plasma vitamin B\n                    <jats:sub>6<\/jats:sub>\n                    levels in either group. These findings suggest that seminal plasma levels of homocysteine are associated with impaired sperm motility and may serve as a potential biomarker for asthenozoospermia. However, further studies are needed to confirm these findings.\n
