Men with oligozoospermia had lower level of seminal plasma pyridoxine compared to normozoospermic men

Abstract

The contribution of pyridoxine on various human disorders has been revealed in so many studies; however, this contribution on poor semen quality has yet to be investigated. Here, we intended to measure the level of seminal plasma pyridoxine (SPP) in men with oligozoospermia compared to normozoospermic men. Thirty-three men with oligozoospermia and forty-three normozoospermic men were randomly enrolled in this study. Collected semen were tested for sperm motility, sperm concentration, semen volume, and pyridoxine status. Liquid chromatography with tandem mass spectrometry was used to measure SPP in the collected samples. There was a significant reduction (p 0.05) with sperm motility, sperm concentration, and semen volume in both tested groups, but, independently, it was found to be positively correlated (p = 0.0154) with male age in oligozoospermic group. Men with oligozoospermia had lower level of SPP compared to normozoospermic men. These results may open a new research gate for the use of pyridoxine in the management of male infertility.
