Phospholipid and Cholesterol Content of Epididymal and Jaculated Ram Spermatozoa and Seminal Plasma in Elation to Cold Shock

Abstract

The concentration of total phospholipid, phosphatidylcholine, phosphatidylethanolamine, and choline plasmalogen in spermatozoa from the caput epididymis of the ram was higher than in spermatozoa from the cauda. The phospholipid composition of spermatozoa from the latter region of the epididymis more closely resembled ejaculated spermatozoa.
