Selected proteins of prostasome-like particles from epididymal cauda fluid are transferred to epididymal caput spermatozoa in bull

During epididymal transit, spermatozoa acquire selected proteins secreted by epithelial cells. We recently showed that P25b, a protein with predictive properties for bull fertility, is transferred from prostasome-like particles present in the cauda epididymal fluid (PLPCd) to the sperm surface. To f...
