Pilot observational prospective cohort study on the use of a novel home-based urinary pregnanediol 3-glucuronide (PDG) test to confirm ovulation when used as adjunct to fertility awareness methods (FAMs) stage 1
Leiva et al.
The finding, in our words
In this pilot study, a home-based urinary PDG test achieved 100% specificity and 85-88% sensitivity for confirming ovulation against serum progesterone. With half of participants finding the test easy to use, the results support further development of decentralised fertility monitoring, though a larger trial is needed for definitive validation.

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.

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.

The study found that the Premom and Easy@Home urine-based luteinizing hormone testing systems provided estimates of peak fertility that were highly correlated with the Clearblue Fertility Monitor, suggesting they are accurate tools for ovulation detection and easy to use at home.
Patients ranked pregnancy chance as the key facilitator for home-based LH urine testing in frozen embryo transfer cycles, while fear of missing ovulation was their main barrier. Healthcare providers agreed on pregnancy rates but cited laboratory capacity as their primary constraint, highlighting that decentralised fertility monitoring must address both patient confidence and system logistics to succeed.
In a randomised trial of 260 women undergoing natural cycle frozen embryo transfer, home-based ovulation monitoring using urine LH tests provided greater feelings of empowerment and treatment discretion compared with hospital monitoring, despite similar increases in anxiety and sadness across both pathways.
