Acrosome status and morphology of human spermatozoa bound to the zona pellucida and oolemma determined using oocytes that failed to fertilize in vitro

1 Apr 1994

Abstract excerpt

It is known that only acrosome-reacted spermatozoa can fuse with the oolemma during normal fertilization with zona pellucida-intact oocytes. The aim of this study was to determine if the oolemma of human zona pellucida-free oocytes selectively binds spermatozoa with normal morphology and a reacted acrosome. Oocytes that failed to fertilize in vitro because of severe sperm defects were used. The zona pellucida was...
