Equex-STM Paste-Added Freezing Medium and Straw Volume Influence Hampshire Crossbred Boar Semen Quality Following Cryopreservation.

Cryopreservation of boar semen is essential for maintaining genetic diversity and improving reproductive efficiency. However, optimizing semen extenders and packaging methods is crucial to enhancing sperm quality and cryotolerance. Equex-STM is commonly used as a surfactant to enhance cryoprotective properties by stabilizing sperm membranes during freezing and thawing.
