Structural changes in human cervical mucus.

T Pal, A K Bhattacharyya

    The Indian Journal of Medical Research
    |February 1, 1989
    PubMed
    Summary

    Human cervical mucus crystallization differs between normally ovulating women and those using oral contraceptives. Oral contraceptives disrupt the typical ferning patterns and crystalline structures observed during the menstrual cycle.

    Area of Science:

    • Reproductive Biology
    • Gynecology
    • Microscopy

    Background:

    • Human cervical mucus undergoes cyclical changes during the menstrual cycle.
    • These changes are influenced by hormonal fluctuations.
    • Crystallization and ferning patterns are indicators of cervical mucus properties.

    Purpose of the Study:

    • To investigate the crystallization phenomenon of human cervical mucus.
    • To compare ferning patterns and crystal conformation in normally ovulating women versus women using oral contraceptives.
    • To understand the impact of oral contraceptives on cervical mucus structure.

    Main Methods:

    • Scanning electron microscopy was employed to examine cervical mucus.
    • Cervical mucus samples were collected on different days of the menstrual cycle.

  • Microscopic analysis focused on crystal conformation and ferning patterns.

    • Main Results:

    • No crystalline structure was observed in either group on day 5 of the menstrual cycle.
    • Square crystals were identified in normally ovulating women on day 21.
    • Women using oral contraceptives exhibited thick, viscous mucus without typical ferning patterns throughout the cycle.

    Conclusions:

    • Oral contraceptive use significantly alters the normal crystallization and ferning patterns of human cervical mucus.
    • The absence of typical ferning in oral contraceptive users suggests a hormonal impact on mucus composition.
    • Scanning electron microscopy is a valuable tool for characterizing cervical mucus changes.
