Abstract
First polar body expulsion in the squirrel monkey ovum occurred at an average of 13.1 h after hCG [human chorionic gonadotropin] injection when observed in culture but could occur as early as 5 h after hCG. The mean time for extrusion of the 2nd polar body was 4.7 h after insemination of the culture with freshly ejaculated spermatozoa (16.3 h after hCG). The earliest time, and therefore also that of sperm capacitation, was 2 h after insemination. First cleavage occurred 16.2 h after insemination.This publication has 0 references indexed in Scilit:
