Abstract
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.

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.

Preterm birth remains a leading cause of perinatal mortality, with rates in the United States rising significantly over the latter half of the twentieth century despite decades of awareness. NaProTechnology's integrated prevention approach, developed at the Pope Paul VI Institute, addresses this problem through systematic risk stratification, hormonal support, infection surveillance, and cervical monitoring across the full course of pregnancy.

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.

Medical protocols in NaProTECHNOLOGY are cycle-phase-targeted regimens — covering ovulation induction, luteal phase hormonal support, hyperprolactinemia management, thyroid optimization, and pre-conceptual supplementation — derived from the biomarker-defined diagnosis rather than empirical stimulation. Consolidating these protocols in a single reference enables practitioners to apply evidence-based, individualized treatment sequences that address root hormonal pathology while supporting natural conception.
