[Progress in the studies of human epididymal secretive proteins].

There are over 200 secretive proteins in the epididymis. Spermatozoa are generally considered to become mature and full-functional after interacting with secretive proteins in the epididymis. This review is aimed at summarizing some aspects of the biochemical, molecular and functional characterization of some new proteins recently detected in human epididymis, and is expected to contribute to further researches on the mechanism of epididymal reproduction and contraception.
