In this prospective clinical study, 892 patients with normal and impaired semen were examined in order to investigate the correlation between the concentration of fibronectin in seminal plasma and the motility of spermatozoa. The fibronectin concentration in seminal plasma, total sperm motility and linear sperm motility were measured. We report here a significant negative correlation between the fibronectin concentration in seminal plasma and total sperm motility (r=-0.3474). There was no link between varicocele and vasectomy, or between varicocele and variation in the concentration of fibronectin. It is concluded that higher concentrations of the acute-phase protein fibronectin may be a cause of severe reduction in sperm motility. The investigation of fibronectin concentrations in seminal fluid could be a new and helpful clinical tool in the assessment of male fertility.
