Introduction

This page presents images from vaginal smears and uterine endometrium dilatation and curettage[1] samples during different phases of the human menstrual cycle.

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.

Human- menstrual uterine endometrium.jpg
Early Proliferative 5 - 9 Smear- early proliferative.jpg Mainly large and small basophilic (blue) stratum spinosum cells.  
Mid Proliferative 9 - 13 Smear- mid-proliferative.jpg Stratum spinosum (blue) increase in size.

Dark precipate outside cells are bacteria.

Human- mid-proliferative uterine endometrium.jpg
Late Proliferative, Ovulatory 13-14 Smear- late-proliferative.jpg mainly stratum corneum (red) which are large and flat.

Appear due to high estrogen levels.

Human- late proliferative uterine endometrium.jpg
Secretory 15 - 22 Smear- secretory.jpg 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.

Human- secretory uterine endometrium.jpg
Late Secretory, (Ischemic) Premenstrual 23 - 28 Smear- late secretory.jpg 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.
