Creighton Model FertilityCare™ System

The Creighton Model FertilityCare™ System is a standardized modification of the Billings Ovulation Method. The research for the CrMS began in 1976 and was fully described in 1980. This system relies upon the observation and charting of biological markers that are essential to understanding a woman’s health and fertility. These "biomarkers" tell the couple when they are naturally fertile and infertile, thus allowing the couple to use the system to either achieve or avoid pregnancy. The biomarkers also identify abnormalities in a woman’s health; therefore, the system may be used along with NaProTechnology (Natural Procreative Technology) to assist with infertility and sub-fertility issues in a natural way while still embracing the union of husband, wife and God.

Furthermore, the CrMS links family planning with gynecological and procreative healthcare and health maintenance. The teachers of the CrMS are trained allied health professionals, and specifically-trained physicians have been educated to incorporate the CrMS into their medical practice.

Group introductory sessions are free and are held monthly at rotating locations throughout the diocese. The full program consists of 8 follow-ups spread out over a 12-month timeframe, which are done on an individual basis.
