Smartphone vs Manual Interpretation of Biomarkers for Ovulation and Luteal Phase Detection (SMOM Study)
Sponsor: Bruyère Health Research Institute.
Summary
This study will compare different combinations of fertility signs (cervical mucus (CM), luteinizing hormone \[LH\], pregnanediol glucuronide \[PDG\], and basal body temperature \[BBT\]) to determine which are most reliable for identifying ovulation and luteal phase length. Thirty existing Premom App users will track daily observations for three menstrual cycles. Participants will record mucus, perform urine tests, upload test strip photos to the Premom App, and measure BBT. Both participant readings and AI-assisted app readings will be analyzed. The main goal is to find which marker pairings give the most accurate picture of ovulation timing and luteal phase length. Secondary goals include understanding ease of use, the number of tests required, and whether the app improves accuracy.

Premom App-Assisted Fertility Tracking
Participants use the Premom smartphone application (Easy Healthcare Corporation) to log daily fertility indicators - cervical mucus (CM), urinary luteinizing hormone (LH) strips, urinary pregnanediol glucuronide (PDG) strips, and basal body temperature (BBT) - over three menstrual cycles. Both participant-read and AI-interpreted app readings are compared to identify ovulation and luteal phase length. \*\*This is an observational study. Participants are not assigned to any intervention; all fertility signs collected are part of their existing self-tracking using the Premom App. The study analyzes these naturally occurring data to compare marker pairings for identifying ovulation and luteal phase length.\*\*
