- Abstract
The objective of this study was to investigate the impact of including hydroxytyrosol (HT) antioxidant on the viability of sperm after the processes of cooling and freezing. HT antioxidants were used in the HF-20 extender at concentrations of 1.25, 2.5, 5, and 10 μg/ml. The HF-20 extender was a basic extender and was used for the control group. The post-thawed semen exhibited significantly higher total motility in the 2.5 HT and 10 HT treatment groups than the control group. The straight line velocity (VSL) of the 2.5 HT group exhibited a significantly high value compared with the control group. However, the average path velocity (VAP), linearity (LIN), straightness index (STR), and wobble (WOB) revealed identical findings across all groups. The findings of the analysis of HOST, normal morphology, major abnormalities, and minor abnormalities revealed that there were no significant differences between the HT groups and the control groups. Nevertheless, the use of HT antioxidant for freezing semen led to a notable enhancement (p < 0.05) in both acrosome integrity and vitality tests when compared to the control group. In this case, the lower quantities of HT (1.25 and 2.5 μg/ml; p < 0.05) preserve the DNA fragmentation compared with the 5 HT, 10 HT, and control groups. In conclusion, the HT antioxidant has shown the capacity to enhance the quality of frozen-thawed spermatozoa and positively influence the viability and integrity of DNA inside the frozen-thawed spermatozoa. Additional research should be conducted to assess the fertility potential of cryopreserved stallion semen.
