The lipid content of epididymal spermatozoa of Rattus norvegicus.
1. Seven major lipids of rat spermatozoa from the caput, corpus and cauda epididymidis were separated and quantitated by TLC. 2. Spermatozoa from the caput epididymidis had a significantly greater (P less than 0.05) content of phospholipid, cholesterol, cholesterol ester and free fatty acid than those from the cauda epididymidis. 3. Spermatozoa from the corpus epididymidis had a significantly greater (P less than 0.05) content of monoglyceride than those from the caput epididymidis and a greater content of phospholipid, cholesterol, free fatty acids and monoglyceride than those from the cauda epididymidis.
