Subfertile men had higher concentrations of miR-155-5p than controls (p = 0.003) and for miR-200c-3p, the difference was borderline statistically significant (p = 0.05). miR-155-5p and miR-200c-3p were also associated with subfertility in men with no metabolic disturbances (p = 0.008, p = 0.004, respectively).
