Carbohydrates mediate the adherence of hamster sperm to oviductal epithelium.


The lower isthmus of the mammalian oviduct appears to serve as a reservoir for sperm that are retained by adherence to the epithelium. By inhibiting sperm binding within excised hamster oviducts and making use of carbohydrate probes, we have characterized the adherence of sperm in the reservoir and established a potential biochemical mechanism for the… (More)
