Lipid composition of buffalo spermatozoa: a cytochemical and biochemical study

Buffalo spermatozoa have been studied cytochemically and biochemically to investigate their phospholipids, which appear to be phosphatidyl choline, lysolecithin, phosphatidyl ethanolamine, phosphatidyl inositol, phosphatidyl glycerol and monogalactosyl diglyceride. Most of them form lipoprotein complexes in the regions of the plasma membrane, the post-nuclear cap and the mid-piece. The lipid composition of buffalo spermatozoa has been compared to and contrasted with that of bull and ram spermatozoa and species differences are indicated.
