    This study explored using vaginal electrical resistance (VER) and salivary electrical resistance (SER) to predict ovulation. Monitoring VER and SER offers a simple method for ovulation prediction and confirmation.

    Area of Science:

    • Reproductive endocrinology
    • Biomedical engineering
    • Gynecology

    Background:

    • Accurate ovulation prediction is crucial for family planning and fertility treatments.
    • Current methods for ovulation detection can be invasive, expensive, or lack precision.
    • Electrical resistance measurements offer a potentially non-invasive and cost-effective alternative.

    Purpose of the Study:

    • To evaluate the efficacy of measuring vaginal electrical resistance (VER) and salivary electrical resistance (SER) for predicting and confirming ovulation.
    • To establish the relationship between VER/SER patterns and the luteinizing hormone (LH) surge.

    Main Methods:

    • Analysis of 18 menstrual cycles from 13 female subjects.
    • Continuous monitoring of vaginal and salivary electrical resistance.

  • Correlation of electrical resistance data with the day of the luteinizing hormone (LH) peak.

    • Main Results:

    • A distinct nadir in VER was observed on day 0 (LH peak day), followed by an increase.
    • SER consistently peaked 5-6 days prior to the LH peak (r=0.94).
    • SER increased 1-2 days before the LH peak after an initial drop.

    Conclusions:

    • Monitoring SER and VER demonstrates potential as a simple, non-invasive method for ovulation prediction.
    • These measurements can aid in both predicting and confirming the timing of ovulation.
    • Further research may validate VER and SER as a practical tool in reproductive health.
