evidence that 0 ca-mtyr effectively inhibited acrosome reactions induced by the zona pellucida was derived from experiments in which sperm were treated with human follicular fluid or control medium and the suspensions were diluted with either 0 ca-mtyr or control medium.4+ human oocytes were added for 1 min ( pulse ) at which time some oocytes were fixed and other oocytes were transferred to sperm-free medium and incubated for 35 min ( chase ) before fixation .
