Fertility-Based Methods of Family Planning: New Horizons

Dr. William Nolan, OB/GYN and minimally invasive surgery fellow, presents a data-driven overview of fertility awareness-based methods (FABMs): their effectiveness, clinical applications, and emerging research.

This lecture equips both patients and providers with the evidence needed to have informed conversations about family planning beyond hormonal contraception, with parallels to NaProTechnology cooperative protocols:

• What FABMs actually are: observable biomarkers (cervical mucus, basal body temperature, urinary hormones) and how they track the fertile window

• Effectiveness data done right: why the CDC's collective 24% failure rate misrepresents individual methods, and what perfect-use and typical-use rates actually show for each category

• The provider knowledge gap: 40-50% of OBGYN trainees lack significant FABM training, and 80-90% cannot explain specific methods to patients

• Method-by-method review: calendar-based, cervical mucus-only (Billings Ovulation Method, Creighton Model), BBT, symptothermal (Sensiplan), and hormonal monitoring methods (including the Marquette Method) with comparative efficacy data

• Why cervical mucus matters most: the physiological basis for why mucus observation outperforms hormone testing in validated FABMs

• Clinical applications beyond family planning: cycle-based approaches to nutrition, exercise, and weight management, with emerging research showing nearly double the weight loss when tailored to cycle phases

• Cooperative hormone therapy and PCOS: how FABMs integrate with NaProTechnology treatment protocols

Includes a rich Q&A with Dr. Whittaker on industry dynamics, clinical collaboration, and making reproductive medicine patient-centric.
