vag·i·nal smear

a smear of debris from the vaginal lumen of mammals, used to determine the stage of their reproductive cycle. It is most useful in subprimate mammals having short estrous cycles; nucleated epithelial cells and leukocytes prevail in the smear during diestrus and proestrus, and cornified cells during estrus.

Determination of estrus cycle stage: Since menstrual disturbance is a typical clinical feature of PCOS women, estrous cycles were examined in all groups of mice by evaluating the cell types in vaginal smears. Cytological examination revealed that both control and vehicle mice had normal estrous cyclicity and showed different stages of the cycle containing proestrus (round, nucleated epithelial cells), estrus (cornified squamous epithelial cells), metestrus (cornified squamous epithelial cells and predominance of leukocytes), and diestrus (predominance of leukocytes) (Table 1).
In addition to the recording and analysis of vaginal smears, we took photographs (Nikon Coolpix l330[R] Camera) to the vaginal opening of every female to observe changes related to the estrous cycle (Byers et al., 2012).

Two questions in the first questionnaire provided an occasion for investigators to discuss dosage as well as the relative merits of clinical judgment and laboratory tests in the practice of medicine: "What dose do you use for each condition?" and "By what means do you judge adequacy of dosage?" In their answers to these questions, many of the physicians discussed the relative merits of the vaginal smear in clinical medicine.
During 3 postpartum months the cell composition of female moose vaginal smears taken from the most extreme section of the vagina shows the early desquamation of 13.7-22.5% of immature superficial cells.
The enrollment criteria included <5% superficial cells on vaginal smear, vaginal pH >5.0, and at least 1 moderate or severe symptom of WA (vaginal dryness, soreness, irritation/itching, pain with intercourse, or bleeding after intercourse).
