Phase	Days (range)	Smear	Smear Description	Uterine Endometrium (D&C)
Menstrual	1 - 4	Click on image to see full size.	Both stratum corneum (red) and stratum spinosum (blue) epithelial cells will mostly blood. Leukocytes and bacteria may also be present.
Early Proliferative	5 - 9		Mainly large and small basophilic (blue) stratum spinosum cells.
Mid Proliferative	9 - 13		Stratum spinosum (blue) increase in size. Dark precipate outside cells are bacteria.
Late Proliferative, Ovulatory	13-14		mainly stratum corneum (red) which are large and flat. Appear due to high estrogen levels.
Secretory	15 - 22		stratum spinosum cells (blue) which are folded or with curled edges. Appear immediately after ovulation due to increase in progesterone. Leukocytes (small black cells) becoming more numerous.
Late Secretory, (Ischemic) Premenstrual	23 - 28		stratum spinosum cells (blue) mainly with a few stratum corneum cells (red). Clustering of cells occurs at this stage. Both leukocytes and bacteria are prevelant.
