Summary The S‐100 and alpha smooth muscle actin (α‐ SMA ) proteins have been localised in epididymal tissue of several mammalian species, but there have been no data for a seasonal work in camel. The aim of this study was to investigate the immunoreactivities of S‐100 and α‐ SMA proteins in the epididymis of dromedary camel during breeding and nonbreeding seasons. The immunopositive signals for both proteins were observed in different regions of camel epididymis. S‐100‐immunopositive signals were noted in both the epididymal epithelium and the intertubular connective tissue, while α‐ SMA signals were confined to the intertubular connective tissue, especially in the peritubular smooth muscle coat and the blood vessels. This study showed an increase in the intensity of S‐100 and α‐ SMA immunoreactions during the breeding season in different regions of camel epididymis than that seen in the nonbreeding season. In conclusion, epididymis might be considered as a source of S‐100 and α‐ SMA proteins in the camel and the secretion of these proteins showed distinct seasonal variations. Further, S‐100 and α‐ SMA may affect the structural and physiological states of the epididymal duct.
