Abstract

The present lectin histochemical comparison of cauda epididymal and ampullary bovine sperm was conducted to investigate whether ampullary secretions are involved in altering the plasma-membrane glycoconjugatesof sperm. A marked redistribution of glycoconjugates between sperm from these two regions was indeed revealed on the basis of changes in binding patterns of the following fluoroscein-isothiocyanate (FITC)-labelled lectins: wheat-germ agglutinin (WGA), Maclura pomifera agglutinin(MPA), Griffonia simplicifolia I agglutinin (GS I) and Bauhinea purpurea agglutinin (BPA). This was evidenced in the first three cases by a relative reversal of staining intensity between the acrosomal and post-acrosomal regions, and by a pronounced increase in the staining of the midpiece. Changes in the distribution of BPA binding sites were limited to the latter phenomenon. The results are compared with previous findings, discussed in the context of the hypermotility characteristic of ampullary sperm and related to previously reported differences in the lectin-binding patterns of the luminal and glandular epithelia.
