Hence, PR monitoring using wearable sensors could be used as one parameter within a multi-parameter fertility awareness-based method.ĭespite years of progress in fertility research, a user-friendly, non-invasive, and affordable method to estimate the female fertile window remains elusive. The aforementioned association was robust to the inter- and intra-person variability of menstrual-cycle length, behavioral, and nutritional profiles. There is a significant increase of the fertile-window PR (collected during sleep) compared to the menstrual phase. PR increase in the ovulatory and mid-luteal phase was robust to adjustment for the collected confounders. ![]() Moreover, PR during the mid-luteal phase was also significantly elevated compared to the fertile window (1.8 beat-per-minute, p < 0.01), and the menstrual phase (3.8 beat-per-minute, p < 0.01). We observed a significant increase in PR during the fertile window compared to the menstrual phase (2.1 beat-per-minute, p < 0.01). 274 ovulatory cycles were recorded from 91 eligible women, with a mean cycle length of 27.3 days (☒.7). Potential behavioral and nutritional confounders were collected daily. Ovulation day was estimated with “Clearblue Digital-Ovulation-urine test”. Participants measured PR during sleep using wrist-worn bracelets with photoplethysmographic sensors. 91 healthy, non-pregnant women, between 22–42 years old, were recruited for a prospective-observational clinical trial. We examine in this study the correlation between pulse rate (PR) and the menstrual phases using wrist-worn PR sensors.
