Post-thaw addition of autologous seminal plasma improves sperm motion characteristics in fair and poor freezer stallions

During semen processing for cryopreservation, the majority of seminal plasma is usually removed, and components with protective effects on sperm may be missing after thawing and within the female reproductive tract. The present study evaluated the effect of post-thaw addition autologous seminal plasma on motion characteristics of stallion sperm with fair (n = 4) or poor (n = 3) freezability. Therefore, pure seminal plasma (group SP1), seminal plasma combined with fresh semen extender (group SP2), or seminal plasma mixed with freezing extender (group SP3) were used to fill 0.5-ml straws and frozen similar to stallion semen.
