Vaginal Cytology, Induced Ovulation and Gestation in the Squirrel Monkey (Saimiri sciureus)

Abstract

Acrosome extracts obtained by treatment of ejaculated rabbit and human sperm with detergents contain an enzyme which disperses the corona radiata of the rabbit ovum. The enzyme was designated corona penetrating enzyme, CPE. The effects of the extracts on the corona was not due to hyaluronidase or a trypsin-like enzyme (TLE) which are also associated with the sperm acrosome.
