Oova 与 ŌURA 科学家在 ASRM 2026 报告：月经周期激素与睡眠及 Readiness 评分的关系

Presented at ASRM 2026, the pilot study analyzed 375 days of combined hormone and wearable data, finding that Sleep and Readiness scores tended to be lowest around the LH surge.

, /PRNewswire/ -- Oova, the leader in longitudinal hormone intelligence, today announced findings from new pilot research conducted with scientists at ŌURA, maker of Oura Ring. Presented at the American Society for Reproductive Medicine (ASRM) 2026 Scientific Congress, the study examined how daily reproductive hormone patterns align with sleep and Readiness across the menstrual cycle.

Wearable technology has made it easier than ever to track sleep and recovery, yet many women still struggle to understand why their scores fluctuate, even when their routines remain consistent. One missing piece may be the hormonal changes occurring throughout the menstrual cycle.

The research combined daily measurements of luteinizing hormone (LH), estrogen metabolite (E3G), and progesterone metabolite (PdG) from Oova with Sleep and Readiness scores from Oura Ring. Across six participants and 375 days of overlapping data, researchers observed that, on average, Sleep and Readiness scores were lowest around the LH surge, which typically precedes ovulation.

Aligning wearable data with hormone-defined cycle phases revealed patterns that were less apparent when examining Oura scores or hormone data alone.

"Women have more access to information about their health than ever before, but we're still learning how different biological systems influence one another," said Dr. Amy Divaraniya, Founder and CEO of Oova. "By bringing together Oura's comprehensive physiological insights with Oova's longitudinal hormone data, we're beginning to uncover relationships that haven't been well understood before. This research is an exciting first step toward a more connected, personalized understanding of women's health."

Key findings from the pilot study

• Sleep and Readiness scores varied across hormone-defined cycle phases. On average, scores were lowest around the LH surge.
• Longitudinal hormone data provided additional context. Aligning daily wearable measurements with hormone-defined cycle phases helped reveal patterns in sleep and readiness.
• Individual patterns may differ. The findings were descriptive and exploratory, based on six participants and 375 days of overlapping data, and were not tested for statistical significance.

The study highlights an emerging opportunity in women's health: combining biological measurements with wearable data to better understand how physiological patterns change throughout the menstrual cycle.

For women tracking their sleep, recovery, and reproductive health, this approach may eventually support more personalized interpretation of wearable metrics, rather than relying on isolated scores or calendar-based cycle predictions.

"Wearables tell us a great deal about how the body is responding day to day," added Amy. "What we're working toward is helping women put those changes into biological context. Hormone patterns are an important part of that picture."

The findings build on Oova's broader research into the relationship between reproductive hormones and women's health. Previous Oova research presented at the American College of Obstetricians and Gynecologists (ACOG) Annual Clinical & Scientific Meeting and published in Obstetrics & Gynecology examined relationships between estrogen patterns, sleep duration, and anxiety among women navigating perimenopause.

The new research was presented on October 27, 2026, at the ASRM Scientific Congress as poster #32614, "Longitudinal Hormone Measurement Alignment with Sleep and Recovery."

The researchers emphasize that this is an early exploratory study. Larger studies are needed to determine whether the observed relationships are reproducible and how hormone-informed wearable interpretation might be used in clinical or consumer settings.
