A mild increase in viscosity of extender using carboxymethyl cellulose improves mitochondrial membrane potential and functional membrane integrity of ram sperm after liquid preservation

Key Points

• Improved mitochondrial membrane potential was observed, enhancing sperm functionality during preservation.
• The viscosity of the extender was selectively increased using carboxymethyl cellulose for this effect, promoting sperm health.
• Assessment using liquid preservation techniques highlighted the importance of viscosity in sperm viability.
• These findings suggest potential advancements in breeding practices, especially in livestock management techniques.
