Description
INTRODUCTION Fowl sperm, unlike their mammalian counterparts, after natural mating or AI, are capable of surviving for a long period of time in the blind-ended SST located in the UVJ and infundibulum of the hen oviduct (Bakst, 1998). Study has revealed that sperm undergoing a process of storage maintain a direct contact with the epithelial cells of the SST, as evidenced by electron microscopy (Van Krey et al., 1967), and those remain free in the SST cannot survive longer (Zavaleta and Ogasawara, 1987). Sperm storage in the oviduct involves an intimate association of sperm with the epithelium of the storage tubules and a stabilization of sperm membrane integrity. Several authors have demonstrated that a strong adherence of sperm cells termed as "sperm binding" to the epithelium of the SST prolongs the life span (Ashizawa and Nishiyama, 1983) and maintains the fertilizing capacity of the resident sperm (Waberski et al., 2006). Therefore, the ability to bind to the epithelial cells of the SST is a very important sperm function with respect to their prolonged survival and fertile life in the oviduct. Although there is much early literature describing the mechanisms underlying the storage of fowl sperm in the hen oviduct, no attention has been concentrated on the acquisition of potential by the sperm in the MRT for the binding capacity.
