GSR and Infertility: The activity of GPx was higher in the infertile group (6.559 nmol·min−1·mL−1) compared to the control (4.317 nmol·min−1·mL−1), while the activity of GR was lower in men with fertility disorders (15.97 nmol·min−1·mL−1) compared to controls (17.74 nmol·min−1·mL−1); (Table 1, Figure 1).
