The presence of sperm-specific surface isoantigens on the egg following fertilization.
Sperm surface isoantigens can be detected on the surface of fertilized eggs by using cytotoxic (complement dependent) sperm-specific isoantisera. These isoantigens cannot be detected on unfertilized eggs. This may indicate their transfer from sperm to egg during fertilization.
