GSTM3, but not IZUMO1, is a cryotolerance marker of boar sperm

Table 2 Correlation coefficients between relative IZUMO1 abundances in both pre-frozen (P-F) and frozen thawed (F-T) spermatozoa and sperm quality parameters in pre-frozen (P-F) and frozen-thawed spermatozoa, evaluated 30 (F-T-30) and 240 (F-T-240) min post-thaw
