Despite extensive documentation of the negative consequences of smoking on a wide range of diseases and disorders, the direct effect of smoking on seminal plasma vitamin B 6 (vitB 6 ) concentration is not addressed yet. Here, we attempted to examine the influence of smoking on the levels of seminal plasma vitB 6 in fertile and subfertile males. One hundred and ninety-five participants were categorized into two groups: fertile men (smokers ( n = 32), nonsmokers ( n = 43)) and subfertile men (smokers ( n = 65), nonsmokers ( n = 55)). According to the World Health Organization criteria, conventional semen analysis was performed for all subjects involved in the study. The concentration of vitB 6 in semen samples was measured by high-performance liquid chromatography tandem-mass spectrometry. There was no significant difference in the mean seminal plasma concentrations of vitB 6 in smokers versus nonsmokers in both fertile ( p =0.5096) and subfertile ( p =0.5224) groups. Besides, no significant correlations were observed between seminal plasma concentration of vitB 6 , duration of smoking, and men's age in all tested groups. In conclusion, these findings elucidate that smoking has no significant impact on the levels of seminal plasma vitB 6 in both fertile and subfertile men.
