Research & Evidence

This comprehensive study evaluated the effectiveness of various fertility awareness methods, including the SymptoThermal Method, across 1,876 participants over a 24-month period.

Key findings: The SymptoThermal Method demonstrated a 99.6% effectiveness rate with perfect use and a 98.2% effectiveness rate with typical use, making it one of the most reliable fertility awareness methods studied.

This study examined the relationship between cervical fluid characteristics and the timing of ovulation, as confirmed by ultrasound and hormone measurements.

Key findings: Peak-type cervical fluid was strongly correlated with the fertile window, appearing an average of 3.7 days before ovulation and continuing through the day of ovulation in 89% of cycles studied.

This research investigated the accuracy of basal body temperature shifts in confirming ovulation compared to ultrasound and serum progesterone measurements.

Key findings: A sustained temperature rise of at least 0.2°C correctly identified the post-ovulatory phase in 94.8% of cycles, with the shift occurring within 48 hours of confirmed ovulation.

This study examined the psychological impacts of learning and applying fertility awareness methods on women's relationship with their bodies and reproductive health.

Key findings: Women who practiced fertility awareness methods for at least 6 months reported significantly higher body literacy, reproductive autonomy, and overall satisfaction with their healthcare decisions compared to control groups.
