Increased Chance of Live Birth Following Use of Connected Ovulation Test System: Outcome Results from a Randomized Controlled Trial
Johnson et al.
The finding, in our words
Women using a connected urine ovulation test in this home-based randomised trial achieved a live birth rate of 16.4% in the first cycle versus 8.5% in controls (odds ratio 2.12, p=0.001). The result demonstrates that decentralised hormone monitoring improves fertility outcomes, with 78% of all pregnancies ending in live birth.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
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.
Women using a home-based, app-connected urine ovulation test achieved pregnancy in 25.4% of first cycles versus 14.7% for those not using tests (p<0.001), with a cumulative two-cycle rate of 40.8% versus 30.0% (p=0.026). This shows that decentralised hormone self-sampling can significantly improve conception rates while reducing intercourse frequency through better cycle timing.
In a study of 46 perinatal nicotine users, dried blood spots and saliva were used weekly to measure reproductive hormones, finding that lower postpartum estradiol and greater peripartum declines in oxytocin were associated with increased nicotine craving and use. This demonstrates the feasibility of decentralised microsampling and remote surveys for longitudinal hormone tracking in vulnerable populations.
In female shift workers, 0.3 mg melatonin reduced climacteric symptoms by 15.8% compared with placebo and improved sleep quality on days off by 35.33%, with no shift interaction; home blood sampling enabled measurement of LH, FSH, estradiol and progesterone.
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.
