In 1972, Drs. Evelyn and John Billings and colleagues published a seminal article demonstrating that 22 women, adequately trained, could detect the approach of ovulation in the fertile window of their menstrual cycle...
Subsequently, Dr. Thomas Hilgers and colleagues introduced a standardized system for women to record these symptomsβ¦This developed further the concept of fertility biomarkers, which provide information about normal ovarian cycle conditions or suggest the presence of pathological conditionsβ¦Many other clinicians and researchers have also expanded our knowledge of the medical applications of fertility biomarkers.
These findings established the biological foundations of a tool of fertility awareness tracking that has facilitated the development of restorative reproductive medicine: an approach that can be applied to identify and treat the underlying causes of infertility/subfertilityβ¦
However, the emergence of in vitro fertilization (IVF) in 1978, with the first successful birth of a baby girl, introduced a solution that operates independently of the causes of infertility. As a result, the RRM approach, which focuses on uncovering the underlying biological causes of infertility, has lost priority in clinical practice.
