Serum zinc concentrations showed a positive correlation with progressive motility (r = 0.577, p = 0.031) and serum copper showed a weak and near-significant correlation with motility (r = 0.115, p = 0.051) ( Figure 2 ).

Some findings, such as the associations for copper and folate with sperm parameters, did not reach statistical significance, also because of the small sample size.
