During the menstrual cycle, the uterus undergoes a series of histologically recognisable cyclic changes under the influence of changing circulating hormonal levels.
This page presents clinical histology images from vaginal smears and uterine endometrium dilatation and curettage samples during different phases of the human menstrual cycle.
Beneath these clinical images are a number of more detailed uterus histology images.

History of the Pap Smear
(Papanicolaou smear, pap test, cervical smear) The text below is from the ABC - Great Moments In Science.
- "Luckily, we have the famous Pap Smear - an excellent way to find cancer of the cervix before it digs in locally and/or spreads throughout the body. The Pap Smear is named after a certain Dr. Papanicolaou - who did a Pap Smear on his wife virtually every day for 20 years.
- George Nikolas Papanicolaou was born in 1883 in Kymi, a small town overlooking the Aegean Sea on the Island of Euboea in Greece. His father, Nikolas Papanicolaou was both the Major of Kymi and a medical doctor. His older brother, Naso, had studied law, so his father convinced George to continue in the family medical tradition. So George studied medicine, and did well, graduating with a degree in honours in 1904............"
Papanicolaou (1933) Hand coloured photomicrographs from the publication showing the human reproductive cycle as revealed by vaginal smears.
This histology technique was originally described in a publication by George Nikolas Papanicolaou in 1942. There are 5 different stains used in the technique and it has been used for many different human bodily fluids (CSF, semen, aspirations). The original protocol has also been modified several ways (Bismarck brown Y deleted).
Dilation and Curettage
Medical procedure where uterine endometrium is collected by Dilation and Curettage (D&C or DnC). This medical procedure is used to diagnose or treat uterine abnormalities or in association with a miscarriage.

- The normal vaginal flora (lactobacillus morphotypes) is replaced by a mixed microbial flora consisting of Gardnerella vaginalis, Mycoplasma hominis and anaerobes.
- Originally described by Gardner and Dukes (1955).
- clinical features - malodorous, thin homogeneous vaginal discharge with elevated vaginal pH above 4.5.
- Nugent's criteria - microbiological diagnosis of bacterial vaginosis, by counting bacterial cell types on Gram stained slides of vaginal smears.
Proposed Gram stain based categorisation
- grade I - when only Lactobacillus cell types (large Gram positive rods) were present.
- grade II (intermediate) when both Lactobacillus and Gardnerella or Bacteroides-Prevotella cell types were present.
- grade III (bacterial vaginosis) when Lactobacillus cell types were absent and only Gardnerella, Bacteroides-Prevotella or Mobiluncus cell types were present.
- grade IV when Gram positive cocci were predominantly present.
