Every woman has the right to know how her menstrual and fertility cycles function in order to understand the way her body works. Unfortunately, most women have not been provided with this information. 

The CREIGHTON MODEL FertilityCare System (CrMS) is based upon the knowledge and understanding of the naturally-occurring phases of a woman's fertility and infertility. CrMS relies upon the standardized observation and charting of biological markers that are essential to a woman's gynecolocical and reproductive health. Now, a woman can know her cycles and use this information for the maintenance of her health. Further, couples can use this knowledge to plan their family and build their future together.

In CrMS, fertility is observed as a part of health, not disease.  It is a system that is specifically not a natural contraceptive.  Rather, it is a true method of family planning … a method that can be used in two ways, to achieve, as well as, avoid pregnancy.  These principles make this system distinctly different from contraception, artificial or natural.
