However, only boron appeared to be equally relevant in both analyzed groups: in the infertile group, it correlated with GPx (r = −0.587) and GR (r = 0.590), and in the healthy control group with SOD (r = −0.467), GPx (r = −0.608) and GR (r = 0.407) (Table 2). The gene discussed is SOD1; the disease is Infertility.
