Comparison of embryo recovery results among the four groups based on median values of diacron-reactive oxygen metabolites (d-ROMs) and the biological antioxidant potential (BAP) parameter before superovulation treatment.

${}^{\mathrm{1}}$  The abbreviations used in the table are as follows: LH – low d-ROM and high BAP values; HH – high d-ROM and high BAP values; HL – high d-ROM and low BAP values; and LL – low d-ROM and BAP values. ${}^{\mathrm{2}}$  Data are expressed as the mean  $\pm$  SEM. ${}^{\text{a–b}}$  Values with different superscript letters in the same column differ significantly ( $P<\mathrm{0.05}$ ).
