First polar body expulsion in the squirrel monkey ovum occurred at an average of 13.1 h after hCG injection when observed in culture but could occur as early as 5 h after hCG. the mean time for extrusion of the second 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.
在培养条件下观察时，松鼠猴卵子的第一极体排出在注射人绒毛膜促性腺激素（hCG）后平均13.1小时发生，但最早可在hCG注射后5小时出现。用新鲜射出的精子对培养物进行授精后，第二极体排出的平均时间为授精后4.7小时（hCG注射后16.3小时）。最早的时间，也就是精子获能的时间，是授精后2小时。第一次卵裂发生在授精后16.2小时。
