Methodologically rigorous effectiveness data for the CrMS are presented, including method-effectiveness and use-effectiveness rates for pregnancy avoidance drawn from prospective cohort studies, demonstrating rates comparable to or exceeding hormonal contraception. Standardized outcome measurement is necessary to establish the CrMS's scientific credibility and to provide practitioners and patients with accurate, evidence-based counseling on system performance.

This 2004 textbook chapter by Thomas W. Hilgers outlines the structure and content of the formal introductory session used to enroll couples in the Creighton Model FertilityCare System (CrMS). It covers the biological foundation of fertility charting, the role of cervical mucus as a biomarker of the reproductive cycle, and the educational framework designed to train couples in systematic, real-time cycle observation.

The CREIGHTON MODEL FertilityCare System (CrMS) rests on a decades-long body of research demonstrating that cervical mucus functions as a physiologically regulated biological valve, opening predictably at the periovulatory estrogen rise and closing in the post-Peak phase. Chapter 15 of Hilgers (2004) synthesizes hormonal, ultrasound, cytologic, and biophysical evidence to establish that a woman's external observation of her Peak Day reliably identifies the fertile window, and documents the system's effectiveness data for both achieving and avoiding pregnancy across a five-study meta-analysis of nearly 1,900 couples.

PCOS (polycystic ovary syndrome), increasingly designated PMOS (polycystic metabolic ovary syndrome) to reflect its metabolic complexity, is far more prevalent than its classic presentation suggests, affecting roughly six percent of reproductive-age women and carrying systemic consequences well beyond fertility disruption. This chapter from the foundational NaProTECHNOLOGY textbook maps the hormonal architecture of the condition, its ovulatory defect patterns, its frequent co-occurrence with endometriosis, and the restorative surgical and cycle-tracking approaches developed at the Pope Paul VI Institute.

Male infertility plays a clinically significant role in a large share of couples who struggle to conceive, yet standard laboratory criteria for semen analysis were designed primarily to predict success with assisted reproduction, not natural fertility. NaProTECHNOLOGY approaches male factor as a diagnosable condition with identifiable root causes, applying medical and surgical options aimed at restoring sperm function and combining that work with fertility-awareness charting to maximize the couple's chances of natural conception.
