Complete Cycle Mapping Using a Quantitative At-Home Hormone Monitoring System in Prediction of Fertile Days, Confirmation of Ovulation, and Screening for Ovulation Issues Preventing Conception
Wegrzynowicz et al.
The finding, in our words
The study found that an at-home urine testing system could predict ovarian reserve, identify up to six fertile days and confirm ovulation by measuring four hormones across the menstrual cycle, potentially screening for ovulatory disorders in a decentralised setting.

The Mira fertility monitor's LH surge and urine E1-3G levels correlated strongly with the ClearBlue Fertility Monitor's LH surge and low-to-high shift in both postpartum and perimenopause transitions, supporting at-home urine hormone monitoring for fertility tracking.

All five at-home urine ovulation predictor kits demonstrated high accuracy (92–97%) when compared with blood LH levels, though sensitivity varied widely from 38% to 77% with Clinical Guard the lowest. Patient experience was comparable across kits, though Clinical Guard was slightly less favoured for future use.

This retrospective case series found that a protocol combining home-based urinary hormone testing with a smartphone application supported fertility management and family planning without unintended pregnancies. The findings suggest that integrating self-collected urinary data with digital tools offers a viable decentralised approach for ovulation prediction.

Quantitative at-home urine monitors clearly demarcated luteal phase transitions, luteinisation, progestation, and luteolysis, and identified anovulation across three clinical scenarios. This proof-of-concept suggests self-collected urine hormone measurements could help women target fertility interventions without clinic visits.
Fertility patients commonly use direct-to-consumer ovulation prediction methods, yet reproductive endocrinologists rate the utility of these tests substantially lower than patients do. This discordance highlights the need for better patient education and guidelines to inform self-collection and interpretation of fertility biomarkers in decentralised care.
