Abstract

Glycoconjugates have an important role in prolifration, differentiation and cell interactions as well as in SPERMATOGENESIS and fertilization. Among them, SIALIC ACID has a very important and unique role. Previous studies have shown this terminal sugar necessity in SPERMATOGENESIS, sperm maturation and fertilization.Therefore we decided to determine SIALIC ACID normal distribution in testicular cells by means of LECTIN histochemistry and peroxidase labelled Weat germ agglutinin (WGA) LECTIN, specific for SIALIC ACID.The pathological states due to different agents could be assessed in comparison with a normal staining pattern. Results show an increase in SIALIC ACID contents from spermatogonia to spermatid formation that followed by sudden reduction in early spermatids. Again in later steps of spermiogenesis to sperm maturation it elevates.There is a moderate and strong reaction in sertoli and leydig cells respectively.These results mean that SIALIC ACID may mask the receptors or cell surface antigens and/or play itself such as a specific receptor in spermatogonial differentiation and meiosis. Elevation of SIALIC ACID in spermiogenesis and mature sperm, rather than a receptor, is related' to its role in masking of sperm surface antigens. In leydig cells sialylated GLYCOCONJUGATEs perhaps act such as a testosterone binding structures that transfer it to blood streem and seminiferous tubules.
