## Abstract The kinetics of capacitated epididymal sperm penetration into cumulus‐intact and completely cumulus‐free mouse ova were studied. Penetration was complete within two hours of insemination in cumulus‐intact ova incubated with 2 × 10^5^ sperm/ml, as evidenced by the attainment of constant
## Abstract Ovulated ova in cumulus masses were obtained from rabbits following isoimmunization with rabbit sperm. They were inseminated in vitro with capacitated sperm, cultured and examined for cleavage and cumulus dispersion. In five experiments only 11 of the 81 (13.6%) ova from the immunized f
