Evidence suporting the existence of sperm maturation in the human epididymis

Zona-free hamster oocytes were used to evaluate the penetrating capacity of permatozoa recovered from the caput, corpus and cauda segments of 5 human epididymides. The ability of spermatozoa to bind tightly to oocytes increased in spermatozoa from successive segments. However, only spermatozoa recov...
