Creighton Model (CrMS)

Creighton Model FertilityCare System (CrMS)

The Creighton Model FertilityCare™ System (CrMS) relies upon the standardized observation and charting of biological markers that are essential to a woman’s health and fertility. These biomarkers tell the couple when they are naturally fertile and infertile, allowing the couple to use the system either to achieve or to avoid pregnancy, as well as telegraph abnormalities in the woman’s health. The CrMS allows a woman to unravel the mysteries of her menstrual cycle.

The CrMS is also the basis for the new women’s health science, NaProTechnology (natural procreative technology).

CrMS is a standardized modification of the Billings Ovulation Method. It is built on research, education and service (the “triangle of support” for the CrMS user) and is an integrated educational system designed to assure the highest quality service delivery possible for the FertilityCare Practitioner and the client couple.

Practitioners accompany each woman (or couple) privately and personally. Learning the Creighton Model System requires attending an introductory session and a minimum of 4 follow-up sessions within a 3-month period. However, it is strongly recommended clients attend all 8 follow-up sessions, which are completed within a year’s time. The introductory session lasts about 1-hour and costs $30, plus an additional $45 for materials. Each follow-up session is $45. No one is turned away due to lack of funds; please do not hesitate to ask. Postpartum and premenopause sessions are also available.
