The effect of combined cryoprotectants on the cryotolerance of boar sperm. [PDF]
Anim BiosciObjective: The frozen semen has the significant advantages of long-term storage and long-range transportation. However, due to the low cryotolerance of boar sperm, the global utilization of frozen boar semen in artificial insemination was less than 1% until the year 2000.Methods: In this study, the effects of five cryoprotectants at different ...

Sperm capacitation as a predictor of boar fertility
Molecular Reproduction and Development, 2023 AbstractPrediction of a boar's fertility level has great economic importance for sow herds. After standard sperm morphology and motility metrics are met, approximately 25% of boars have less than 80% conception rates. Due in part to the many factors involved in the fertilization process, a multifactorial model incorporating multiple relevant sperm ...
