Vaginal swabs during jamaicahugepussy show primarily polymorphonuclear leukocytes and a few epithelial cells during late diestrus. Leukocytes remain the predominant cell type having black vaginas images cellular debris.

The cycle then repeats. The contents of the oviducts were flushed using M2 media into a petri dish to look for oocytes as evidence that ovulation had occurred.

Presented here Figure 1 is an estrous cycle identification tool that shows the changes in cell populations during the entire cycle.
