| Table 1 - Progressive Changes in Maturing Ovarian Eggs during the Time Interval between Capulaticm and Ovulation | |||
| Time elapsed since copulation (hrs.) | No. of cases observed | Condition of the egg | Condition of the follicles |
|---|---|---|---|
| 0 | 10 | Egg fully grown. Nucleus vesicular, in some cases vesicular tetrads present | Average diameter 970 um. The follicular epithelium forms a spider web. In some cases the egg is in a cumulus |
| 2 | 9 | The vesicular nucleus present in most cases. In all cases tetrads present | Spider web arrangement of granulosa. Liquor folliculi increasing in amount. Disintegration of follicle cells adjacent to
corona begins |
| 4 | 7 | Vesicular membranes have disappeared. Only traces present. Tetrads free in cytoplasm type | Average diameter 1045 um. Follicular epithelium changing from spider web to cumulus |
| 6 | 6 | Chromatic material decreases very much in size and forms the first spindle. No trace of nuclear membrane left | Most follicles in cumulus type. The liquor folliculi becomes increasingly viscous |
| 7 | 4 | First polar body extruded in many cases. The remaining chromatin moves sideways | As in preceding type |
| 8 | 10 | First polar body present in all cases | Average diameter 1125 um |
| 9 | 4 | First polar body present. Second spindle in place and ready to form the second polar body | Average diameter 1310 um. Egg almost free in follicle |
