Creighton Model FertilityCare System

History of Development

On July 25, 1968, Pope Paul VI issued an encyclical letter Humanae Vitae (of Human Life). At this time, Dr. Thomas Hilgers, MD, Dip. ABOG, CFCE, CFCMC, was a senior medical student. He took Pope Paul VI's encyclical to heart and began to research the natural regulation of fertility. After several years of preparation, research officially began for the Creighton Model FertiltiyCare System on April 1, 1976. On August 6, 1978, Pope Paul VI died. On that same day, Dr. Hilgers and his wife, Susan, made a commitment to fully respond to the appeal that Humanae Vitae made to "men of science" and "physicians and health care professionals." This commitment led to the opening of the Pope Paul VI Institute for the Study of Human Reproduction in September 1985. In 1991, the continued research of the Pope Paul VI Institute for the Study of Human Reproduction led to the development of NaProTECHNOLOGY, which is a new women's reproductive health science.

Creighton Model FertilityCare System

The Creighton Model FertiltityCare System teaches a woman how to chart her reproductive cycle. The woman's practitioner will teach her how to observe and chart "biological markers." These biological markers enable a woman to understand when she is fertile and infertile as well as help her identify health issues.
