Works with PCOS

PCOS can cause false LH surges that make strips unreliable. OvuScope reads estrogen via saliva ferning — a more consistent signal for irregular cycles, giving you clarity when other methods can't.

Understanding Ferning

  • trending_up
    1. Estrogen Rises

    As you approach ovulation, estrogen levels surge. This changes the salt concentration in your saliva — a natural, measurable biomarker.

  • ac_unit
    2. Crystallization

    When dried, the elevated salt content causes your saliva to crystallize into distinctive fern-shaped patterns visible under 100x magnification.

  • event_available
    3. Fertile Window Detected

    These fern patterns appear 24–72 hours before ovulation, giving you the maximum fertile window to plan conception with confidence.
