Seminal plasma vitamin B6 levels in men with asthenozoospermia and men with normal sperm motility, a measurement using liquid chromatography with tandem mass spectrometry

There is growing evidence that vitamin B-6 has a valuable contribution in maintaining normal sperm parameters; however, this contribution has not yet well-identified. Here, we aimed to measure the level of seminal plasma vitamin B-6 in men with asthenozoospermia compared to men with normal sperm motility. Ninety-seven human males with asthenozoospermia and eighty-eight human males with normal sperm motility (control) were recruited in this study. Collected semen samples were assessed for sperm motility, sperm count and semen volume. Liquid chromatography with tandem mass spectrometry was used to measure seminal plasma vitamin B-6 concentrations. A highly significant difference (p < .0001) in concentrations of seminal plasma vitamin B-6 was found between asthenozoospermic and control groups. Besides, no statistical correlations were found between seminal plasma vitamin B-6 level and sperm motility, sperm count, semen volume and men age in both tested groups. In conclusion, men with asthenozoospermia have lower seminal plasma vitamin B-6 level compared to men with normal sperm motility. Also, seminal plasma vitamin B-6 was found not to be correlated with sperm motility and count, semen volume and men age in both tested groups. These results may provide new contribution in the management of male infertility.
