The anti-mouse sperm monoclonal antibody OBF13 did not react with fresh epididymal
sperm. However, when sperm were incubated in a culture medium capable of inducing
capacitation, the entire head of the sperm began to react with this antibody. This change of
reactivity was not observed when sperm were incubated in a Ca 2+-free medium. The
change of the reactivity to the antibody was studied in relation to the fertilizing ability of
sperm as measured in an in vitro fertilization system; a significant correlation was observed …
