    A new, rapid vaginal cytology technique using Lugol solution accurately identifies the rat

    Area of Science:

    • Veterinary Science
    • Animal Reproduction
    • Cytology

    Background:

    • Vaginal cytology is standard for determining rat estrous cycles.
    • Current staining methods are time-consuming and labor-intensive.

    Purpose of the Study:

    • To introduce a simple, fast, and accurate method for identifying the day of the sexual cycle in rats.
    • To provide an alternative to traditional, time-consuming staining techniques.

    Main Methods:

    • A novel technique utilizing Lugol solution for vaginal smear analysis.
    • Smears collected at 8:00 a.m. are mixed with one drop of Lugol solution.
    • Direct microscopic examination of the prepared slides.

    Main Results:

    • The Lugol solution technique allows for precise identification of the rat's sexual cycle day.
