从78只性成熟Wistar大鼠回收的933个活卵中收集数据。从排卵前授精的大鼠中回收的160个卵子中，92%受精，1.4%的受精卵异常。随着排卵后授精时间的延长，受精率下降，从授精9-12小时的大鼠中回收的375个卵子中，受精率为71%。排卵后，43%的受精卵异常。平均有1.2（1.13）个精子穿透了每个受精卵;排卵后不同时间授精的大鼠卵中精子数量无明显差异。描述了卵原核的变化。G. R. R.
Data were collected from 933 viable ova recovered from 78 sexually mature Wistar rats. Of the 160 ova recovered from rats inseminated before ovulation 92% were fertilized; 1.4% of the fertilized ova were abnormal. As the time of insemination increased after ovulation the percentage of ova fertilized decreased to 71% of 375 recovered from rats inseminated 9-12 hrs. after ovulation; 43% of the fertilized ova were abnormal. An average of 1.2 (1.13) spermatozoa had penetrated each fertilized ovum; there was no appreciable difference in the number of spermatozoa in ova from rats inseminated at different times after ovulation. Pronuclear changes in the ova are described. G. R. R.
